![How to Scrape SimilarWeb Website Traffic Analytics](https://scrapfly.io/blog/content/images/2024/03/how-to-scrape-similarweb-banner-light-1.svg)

SimilarWeb is a leading platform specializing in web analytics, acting as a directory for worldwide website traffic. Imagine the insights and SEO impact would scraping SimilarWeb allow for!

In this guide, we'll explain how to scrape SimilarWeb through a step-by-step guide. We'll scrape comprehensive domain traffic insights, websites comparing data, sitemaps, and trending industry domains. Let's get started!

## [Latest SimilarWeb Scraper Code](https://github.com/scrapfly/scrapfly-scrapers/tree/main/similarweb-scraper)

This tutorial covers popular web scraping techniques for education. Interacting with public servers requires diligence and respect and here's a good summary of what not to do:

- Do not scrape at rates that could damage the website.
- Do not scrape data that's not available publicly.
- Do not store <abbr title="Personally Identifiable Information">PII</abbr> of EU citizens who are protected by GDPR.
- Do not repurpose the _entire_ public datasets which can be illegal in some countries.

Scrapfly does not offer legal advice but these are good general rules to follow in web scraping and for more you should consult a lawyer.

## Why Scrape SimilarWeb?

Web scraping SimilarWeb provides us with detailed valuable insights into websites' traffic, which can be valuable across different aspects.

- **Competitor Analysis**  
One of the key features of web analytics is analyzing the industry peers and benchmarking against their traffic. Scraping SimilarWeb enables such data retrieval, allowing business to **fine-tune their strategies to meet their competitors** and gain a competitive edge.  
  
- **SEO and Keyword Analysis**  
Search Engine Optimization (SEO) is crucial for driving traffic into the domains. SimilarWeb data extraction provides **comprehensive insights into the [SEO keywords](https://scrapfly.io/blog/web-scraping-google-seo-keywords/) and search engine rankings**, allowing for better online presence and visibility.  
  
- **Data-Driven Decision Making**  
The search trends are aggressive and fast-changing. Therefore, utilizing scraping SimilarWeb for **data-based insights** is crucial for supporting decision-making and defining strategies.

Have a look at our comprehensive guide on [web scraping use cases](https://scrapfly.io/use-case) for further details.

## Setup

To web scrape SimilarWeb, we'll use Python with a few community packages.

- [httpx](https://pypi.org/project/httpx/): To request SimilarWeb pages and get the data as HTML. Feel free to replace [httpx](https://scrapfly.io/blog/web-scraping-with-python-httpx/) with any other HTTP client, such as [requests](https://pypi.org/project/requests/).
- [parsel](https://pypi.org/project/parsel/): To [parse the HTML](https://scrapfly.io/blog/parsing-html-with-css/) retrieved using web selectors, such as [XPath](https://scrapfly.io/blog/parsing-html-with-xpath/) and [CSS](https://scrapfly.io/blog/parsing-html-with-css/).
- [JMESPath](https://scrapfly.io/blog/parse-json-jmespath-python/): To refine the JSON datasets we get and remove the unnecessary details.
- [asyncio](https://pypi.org/project/asyncio/): To increase our SimilarWeb [scraper speed](https://scrapfly.io/blog/web-scraping-speed/#async-requests) by running it asynchronously.
- [loguru](https://pypi.org/project/loguru/): Optional prerequisite to monitor our code through colored terminal outputs.

Since `asyncio` comes pre-installed in Python, we'll only have to install the other packages using the following `pip` command:

```shell
pip install httpx parsel jmespath loguru
```

## How to Discover SimilarWeb Pages?

[Crawling](https://scrapfly.io/blog/crawling-with-python/) sitemaps is a great way to discover and navigate pages on a website. Since they **direct search engines for organized indexing**, we can use them for scraping, too!

The SimilarWeb sitemaps can be found at [similarweb.com/robots.txt](https://www.similarweb.com/robots.txt), which looks like this:

```html
User-agent: *
Disallow: */search/
Disallow: */adult/*
Disallow: /corp/*.pdf$
Disallow: /corp/solution/
Disallow: /corp/lps/
Disallow: /corp/get-data/
Disallow: /silent-login/
Disallow: /signin-oidc/
Disallow: /signout-oidc/
Sitemap: https://www.similarweb.com/corp/sitemap_index.xml
Sitemap: https://www.similarweb.com/blog/sitemap_index.xml

# MMN- sMd` -NM
# Md:` `sh`` .sMM
# Mdms+-.```-hmMds
# oMMMMMMMMo
#
# OFFICIAL MEASURE OF THE DIGITAL WORLD
#
```

Each of the above sitemap indexes represents a group of related sitemaps. Let's explore the latest sitemap `/sitemaps/sitemap_index.xml.gz`. It's a `gz` compressed file to save bandwidth, which looks like this after extracting:

```xml
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<sitemapindex xmlns="http://www.sitemaps.org/schemas/sitemap/0.9">
    ....
    <sitemap>
        <loc>https://www.similarweb.com/sitemaps/top-websites-trending/part-00000.gz</loc>
        <lastmod>2023-08-17</lastmod>
    </sitemap>

    <sitemap>
        <loc>https://www.similarweb.com/sitemaps/website/part-00000.gz</loc>
        <lastmod>2023-08-17</lastmod>
    </sitemap>

    <sitemap>
        <loc>https://www.similarweb.com/sitemaps/website_competitors/part-00000.gz</loc>
        <lastmod>2023-08-17</lastmod>
    </sitemap>

</sitemapindex>
```

We have reached another sitemap index for several website insight pages. Let's scrape SimilarWeb sitemap for the trending websites.

Python:
```python
import asyncio
import json
from typing import List
from httpx import AsyncClient, Response
from parsel import Selector
from loguru import logger as log

# initialize an async httpx client
client = AsyncClient(
    # enable http2
    http2=True,
    # add basic browser like headers to prevent getting blocked
    headers={
        "Accept-Language": "en-US,en;q=0.9",
        "User-Agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/96.0.4664.110 Safari/537.36",
        "Accept": "text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,image/apng,*/*;q=0.8",
        "Accept-Encoding": "gzip, deflate, br",
    },
)

def parse_sitemaps(response: Response) -> List[str]:
    """parse links for bestbuy sitemaps"""
    # decode the .gz file
    xml = response.content.decode('utf-8')
    selector = Selector(xml)
    data = []
    for url in selector.xpath("//url/loc/text()"):
        data.append(url.get())
    return data

async def scrape_sitemaps(url: str) -> List[str]:
    """scrape link data from bestbuy sitemaps"""
    response = await client.get(url)
    urls = parse_sitemaps(response)
    log.success(f"scraped {len(urls)} urls from sitemaps")    
    return urls
```

ScrapFly
```python
import asyncio
import json
from typing import List
from parsel import Selector
from loguru import logger as log
from scrapfly import ScrapeConfig, ScrapflyClient, ScrapeApiResponse

SCRAPFLY = ScrapflyClient(key="Your ScrapFly API key")

def parse_sitemaps(response: ScrapeApiResponse) -> List[str]:
    """parse links for bestbuy sitemap"""
    bytes_data = response.scrape_result['content'].getvalue()
    # decode the .gz file
    xml = bytes_data.decode('utf-8')
    selector = Selector(xml)
    data = []
    for url in selector.xpath("//url/loc/text()"):
        data.append(url.get())
    return data

async def scrape_sitemaps(url: str) -> List[str]:
    """scrape link data from bestbuy sitemap"""
    response = await SCRAPFLY.async_scrape(ScrapeConfig(url, asp=True, country="US"))
    urls = parse_sitemaps(response)
    log.success(f"scraped {len(urls)} urls from sitemaps")
    return urls
```

Run the code:
```python
async def run():
    urls = await scrape_sitemaps(
        url="https://www.similarweb.com/sitemaps/top-websites-trending/part-00000.gz"
    )
    # save the data to a JSON file
    with open("sitemap_urls.json", "w", encoding="utf-8") as file:
        json.dump(urls, file, indent=2, ensure_ascii=False)

if __name__ == " __main__":
    asyncio.run(run())
```

In the above code, we define an `httpx` client with basic browser [headers](https://scrapfly.io/blog/how-to-avoid-web-scraping-blocking-headers/) to avoid blocking and define two functions. Let's break them down:

- `parse_sitemaps`: For parsing the URLs inside the XML file after extracting it.
- `scrape_sitemaps`: for requesting the sitemap URL while utilizing the parsing logic.

The above code will save more than 10,000 URLs to the `sitemap_urls.json` file. Here's an example output:
```json
[
  "https://www.similarweb.com/top-websites/food-and-drink/groceries/trending/",
  "https://www.similarweb.com/top-websites/gambling/bingo/trending/",
  "https://www.similarweb.com/top-websites/travel-and-tourism/transportation-and-excursions/trending/",
  "https://www.similarweb.com/top-websites/health/health-conditions-and-concerns/trending/",
  "https://www.similarweb.com/top-websites/finance/investing/trending/",
  ....
]
```

The above URLs represent website ranking pages for different industries. Let's scrape them next!

## How to Scrape SimilarWeb Trending Websites?

The trending website pages on SimilarWeb represent two related insights:

- **Trending**: The month's trending websites and their traffic changes.
- **Ranking**: The industry's overall website rankings with essential traffic insights.

Let's scrape the **trending** website section. Go to any industry trending page, such as the one for [software](https://www.similarweb.com/top-websites/computers-electronics-and-technology/programming-and-developer-software/), and you will get a similar web page:

![How to Scrape SimilarWeb Website Traffic Analytics](https://scrapfly.io/blog/content/images/2024/03/similarweb-trending-pages-1.webp)
_Website rankings on SimilarWeb_

We can parse the above SimilarWeb page using selectors to scrape it. However, there is a better approach: [hidden web data](https://scrapfly.io/blog/how-to-scrape-hidden-web-data/).

To locate the website ranking hidden web data, follow the below steps:
- Open the [browser developer tools](https://scrapfly.io/blog/browser-developer-tools-in-web-scraping/) by clicking the `F12` key.
- Search for the XPath selector: `//script[@id='dataset-json-ld']`.

After following the above steps, you will find the below data:

![How to Scrape SimilarWeb Website Traffic Analytics](https://scrapfly.io/blog/content/images/2024/03/similarweb-ranking-websites-source.svg)

The above data is the same on the web page but before getting rendered into the HTML. To scrape it, we'll select its associated `script` tag and then parse it.

Python:
```python
import asyncio
import json
from typing import List, Dict
from httpx import AsyncClient, Response
from parsel import Selector
from loguru import logger as log

# initialize an async httpx client
client = AsyncClient(
    # enable http2
    http2=True,
    # add basic browser like headers to prevent getting blocked
    headers={
        "Accept-Language": "en-US,en;q=0.9",
        "User-Agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/96.0.4664.110 Safari/537.36",
        "Accept": "text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,image/apng,*/*;q=0.8",
        "Accept-Encoding": "gzip, deflate, br"
    },
)

def parse_trending_data(response: Response) -> List[Dict]:
    """parse hidden trending JSON data from script tags"""
    selector = Selector(response.text)
    json_data = json.loads(selector.xpath("//script[@id='dataset-json-ld']/text()").get())["mainEntity"]
    data = {}
    data["name"] = json_data["name"]
    data["url"] = str(response.url)
    data["list"] = json_data["itemListElement"]
    return data

async def scrape_trendings(urls: List[str]) -> List[Dict]:
    """parse trending websites data"""
    to_scrape = [client.get(url) for url in urls]
    data = []
    for response in asyncio.as_completed(to_scrape):
        response = await response    
        category_data = parse_trending_data(response)
        data.append(category_data)
    log.success(f"scraped {len(data)} trneding categories from similarweb")
    return data
```

ScrapFly
```python
import asyncio
import json
from typing import List, Dict
from loguru import logger as log
from scrapfly import ScrapeConfig, ScrapflyClient, ScrapeApiResponse

SCRAPFLY = ScrapflyClient(key="Your ScrapFly API key")

def parse_trending_data(response: ScrapeApiResponse) -> List[Dict]:
    """parse hidden trending JSON data from script tags"""
    selector = response.selector
    json_data = json.loads(selector.xpath("//script[@id='dataset-json-ld']/text()").get())["mainEntity"]
    data = {}
    data["name"] = json_data["name"]
    data["url"] = response.scrape_result["url"]
    data["list"] = json_data["itemListElement"]
    return data

async def scrape_trendings(urls: List[str]) -> List[Dict]:
    """parse trending websites data"""
    to_scrape = [ScrapeConfig(url, asp=True, country="US") for url in urls]
    data = []
    async for response in SCRAPFLY.concurrent_scrape(to_scrape):
        category_data = parse_trending_data(response)
        data.append(category_data)
    log.success(f"scraped {len(data)} trneding categories from similarweb")
    return data    
```

Run the code:
```python
async def run():
    data = await scrape_trendings(
        urls=[
            "https://www.similarweb.com/top-websites/computers-electronics-and-technology/programming-and-developer-software/",
            "https://www.similarweb.com/top-websites/computers-electronics-and-technology/social-networks-and-online-communities/",
            "https://www.similarweb.com/top-websites/finance/investing/"
        ]
    )
    # save the data to a JSON file
    with open("trendings.json", "w", encoding="utf-8") as file:
        json.dump(data, file, indent=2, ensure_ascii=False)

if __name__ == " __main__":
    asyncio.run(run())
```

We use the previously defined `httpx` client and define additional functions:

- `parse_trending_data`: For extracting the page JSON data from the hidden `script` tag, organizing the data by removing the JSON schema details and adding the URL.
- `scrape_trendings`: For adding the page URLs to a list and requesting them concurrently.

Here is a sample output of the above SimilarWeb scraping code:

```json
[
  {
    "name": "Most Visited Social Media Networks Websites",
    "url": "https://www.similarweb.com/top-websites/computers-electronics-and-technology/social-networks-and-online-communities/",
    "list": [
      {
        "@type": "ListItem",
        "position": 1,
        "item": {
          "@type": "WebSite",
          "name": "facebook.com",
          "url": "https://www.similarweb.com/website/facebook.com/"
        }
      },
      ....
    ]
  },
  ....
]
```

Next, let's explore the exciting part of our SimilarWeb scraper: **website analytics**! But before this, we must solve a SimilarWeb scraping blocking issue: **validation challenge**.

## How to Avoid SimilarWeb Validation Challenge?

The SimilarWeb validation challenge is a [web scraping blocking](https://scrapfly.io/blog/how-to-scrape-without-getting-blocked-tutorial/) mechanism that blocks HTTP requests from clients without JavaScript support. It's a JavaScript challenge that's automatically bypassed after 5 seconds when requesting the domain for the first time:

![How to Scrape SimilarWeb Website Traffic Analytics](https://scrapfly.io/blog/content/images/2024/03/similarweb-request-processing.webp)
_SimilarWeb scraping blocking: request processing_

Since we scrape SimilarWeb with an HTTP client that doesn't support JavaScript (httpx), requests sent to pages with this challenge will be blocked due to not evaluating it:

```python
from httpx import Client

client = Client(
    # enable http2
    http2=True,
    # add basic browser like headers to prevent getting blocked
    headers={
        "Accept-Language": "en-US,en;q=0.9",
        "User-Agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/96.0.4664.110 Safari/537.36",
        "Accept": "text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,image/apng,*/*;q=0.8",
        "Accept-Encoding": "gzip, deflate, br",
    },
)

response = client.get("https://www.similarweb.com/website/google.com/")
print(response.text)
"""
<!DOCTYPE html><html><head><meta charset="utf-8">
<title>Challenge Validation</title>
<script type="text/javascript">function cp_clge_done(){location.reload(true);}</script>
<script src="/_sec/cp_challenge/sec-cpt-int-4-3.js" async defer></script>
<script type="text/javascript">sessionStorage.setItem('data-duration', 5);</script>
</html>
"""
```

To avoid the SimilarWeb validation challenge, we can use a [headless browser](https://scrapfly.io/blog/scraping-using-browsers/) to complete the challenge automatically using JavaScript. However, there's a trick we can use to bypass the challenge without JavaScript: **cookies**!

When the validation challenge is solved, the website cookies are updated with the challenge state, so it's not triggered again.

We can make use of [cookies for web scraping](https://scrapfly.io/blog/how-to-handle-cookies-in-web-scraping/) to bypass the validation challenge automatically! To do this, we have to get the cookie value:

- Go to any protected SimilarWeb page with the challenge.
- Open the browser developer tools by pressing the `F12` key.
- Select the `Application` tab and choose cookies.
- Copy the `_abck` cookie value, which is responsible for the challenge.

After following the above steps, you will find the SimilarWeb saved cookies:

![How to Scrape SimilarWeb Website Traffic Analytics](https://scrapfly.io/blog/content/images/2024/03/similarweb-cookies-1.webp)
_SimilarWeb cookies_

Adding the `_abck` cookie to the requests will authorize them against the challenge:

```python
from httpx import Client

client = Client(
    # enable http2
    http2=True,
    # add basic browser like headers to prevent getting blocked
    headers={
        "Accept-Language": "en-US,en;q=0.9",
        "User-Agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/96.0.4664.110 Safari/537.36",
        "Accept": "text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,image/apng,*/*;q=0.8",
        "Accept-Encoding": "gzip, deflate, br",
        "Cookie": "_abck=85E72C5791B36ED327B311F1DC7461A6~0~YAAQHPR6XIavCzyOAQAANeDuYgs83VF+IZs6MdB2WGsdsp5d89AWqe1hI+IskJ6V24OYvokUZSIn2Om9PATl5rqminoOTHQYZAMWO5Om8bcXlT3q2D9axmG+YQkS/77h/7O98vFFDrFX8Jns/upO+RbomHm7SxQ0IGk0yS80GGbWBQoSkxN+770ltBb9vdyT/7ShUBl3eKz/iLfyMSe4SyOxymE0pQL0pch0FJhvCiC2CD4asMBXGBNMQv2qvA553uO9bwz4Yr1X/7zLPOm6Vn2bz242O7rephGPmVud25Yc3Khs0oEqiQ4pgMvCy/NGIXTlVKN8anBc5QlnqGw7dq8kLqDrID9HqzbqusS9p5gkNUd4A2QJXDj80pjB9k4SWitpn1zRhsUNUYzrfvHMeGiDZhNuTYSq3sMcYg==~-1~-1~-1"
    },
)

response = client.get("https://www.similarweb.com/website/google.com/")
print(response.text) # full HTML response
```

We can successfully bypass the validation challenge. However, the **cookie value has to be rotated** as it can expire. The rotation logic can also be automated with a **headless browser** for better rotation efficiency.

## How to Scrape SimilarWeb Website Analytics?

The SimilarWeb website analytics pages is a powerful feature that includes comprehensive insights about the domain, including:

- **Ranking**: The domain's category, country, and global rank.
- **Traffic**: Engagement analysis including total visits, bounce rate, and visit duration.
- **Geography**: The domain's traffic by top countries.
- **Demographics**: The visitors' composition distribution by age and gender.
- **Interests**: The visitors' interests by categories and topics.
- **Competitors**: The domain's competitors and alternatives and their similarities.
- **Traffic sources**: The domain's traffic by its source, such as search, direct, or [emails](https://scrapfly.io/blog/how-to-scrape-emails-using-python/).
- **Keywords**: Top keywords visitors use to search the domain.

First, let's look at what the website analysis page on our target website looks like by targeting a specific domain: [Google.com](https://scrapfly.io/blog/how-to-scrape-google/). Go to the [domain page SimilarWeb](https://www.similarweb.com/website/google.com/), and you will get a page similar to this:

![How to Scrape SimilarWeb Website Traffic Analytics](https://scrapfly.io/blog/content/images/2024/03/similarweb-analytics-page.webp)
_Google analytics page on SimilarWeb_

The above page data are **challenging to scrape using selectors**, as they are mostly located in charts and graphs. Therefore, we'll use the **hidden web data** approach.

Search through the HTML using the following XPath selector:  
`//script[contains(text(), 'window. __APP_DATA__')]`. The `script` tag found contains a comprehensive JSON dataset with the domain analysis data:

![How to Scrape SimilarWeb Website Traffic Analytics](https://scrapfly.io/blog/content/images/2024/03/similarweb-website-analytics-source.svg)

To scrape SimilarWeb traffic analytics pages, we'll select this `script` tag and parse the inside JOSN data.

Python:
```python

from httpx import AsyncClient, Response
from parsel import Selector

Let's break down the above SimilarWeb scraping code:
- `parse_hidden_data`: For selecting the `script` tag that contains the domain analysis data and then parsing the JSON data using regex to execute the HTML tags.
- `scrape_website`: For creating the domain analytics page URLs on SimilarWeb and then requesting them concurrently while utilizing the parsing logic.

Here's an example output of the results we got:

The above web scraping SimilarWeb results are the **raw analytics data**. We can use it for further analysis ourselves!

## How to Scrape SimilarWeb Website Comparing Pages?
The SimilarWeb comparing pages are similar to the dedicated pages for website analytics. They include **traffic insights for two compared domains**.

For example, let's compare [Twitter](https://scrapfly.io/blog/how-to-scrape-twitter/) and [Instagram](https://scrapfly.io/blog/how-to-scrape-instagram/) using our target website. Go to the [compare page on SimilarWeb](https://www.similarweb.com/website/twitter.com/vs/instagram.com/), and you will get a similar page:

![How to Scrape SimilarWeb Website Traffic Analytics](https://scrapfly.io/blog/content/images/2024/03/similarweb-compare-pages.webp)
_SimilarWeb compare pages_

To scrape the above data, we'll use the hidden data approach again using the previously used selector `//script[contains(text(), 'window. __APP_DATA__')]`. The data inside the `script` tag looks like the following:

![How to Scrape SimilarWeb Website Traffic Analytics](https://scrapfly.io/blog/content/images/2024/03/similarweb-website-compare-source.svg)

Similar to our previous SimilarWeb scraping code, we'll select the `script` tag and parse the inside data.

Run the code:
```python
async def run():
    comparing_data = await scrape_website_compare(
        first_domain="twitter.com",
        second_domain="instagram.com"
    )
    # save the data to a JSON file
    with open("websites_compare.json", "w", encoding="utf-8") as file:
        json.dump(comparing_data, file, indent=2, ensure_ascii=False)

if __name__ == " __main__":
    asyncio.run(run())
```

In the above code, we use the previously defined `parse_hidden_data` to parse data from the page and define two additional functions:

- `parse_website_compare`: For organizing the JSON data and parsing it to exclude unnecessary details with JMESPath.
- `scrape_website_compare`: For defining the SimilarWeb comparing URL and requesting it, while utilizing the parsing logic.

Here is a sample output of the results we got:

With this last feature, our SimilarWeb scraper is complete. It can scrape tons of website traffic data from sitemaps, **trending**, **domain**, and **comparing pages**. However, our scraper will soon encounter a major challenge: **scraping blocking**!

## Bypass SimilarWeb Web Scraping Blocking

We can successfully scrape SimilarWeb for a limited amount of requests. However, attempting to scale our scraper will lead SimilarWeb to [block the IP address](https://scrapfly.io/blog/how-to-avoid-web-scraping-blocking-ip-addresses/) or request us to log in:

![How to Scrape SimilarWeb Website Traffic Analytics](https://scrapfly.io/blog/content/images/2024/03/similarweb-requesting-login.webp)
_SimilarWeb scraping blocking_

To scrape SimilarWeb without getting blocked, we'll use ScrapFly - a web scraping API that allows for scraping at scale by providing:

- [Anti-scraping protection bypass](https://scrapfly.io/docs/scrape-api/anti-scraping-protection) - For scraping any website without getting blocked.
- [Residential proxies](https://scrapfly.io/docs/scrape-api/proxy) in over 50 countries - For scraping from almost any geographical location while also preventing IP address throttling and blocking.
- [JavaScript rendering](https://scrapfly.io/docs/scrape-api/javascript-rendering) - For scraping dynamic web pages through cloud headless browsers wihtout running them yourself.
- Easy to use [Python](https://scrapfly.io/docs/sdk/python) and [Typescript](https://scrapfly.io/docs/sdk/typescript) SDKs, as well as [Scrapy integration](https://scrapfly.io/docs/sdk/scrapy).
- [And much more!](https://scrapfly.io/docs/scrape-api/getting-started)

![How to Scrape SimilarWeb Website Traffic Analytics](https://scrapfly.io/blog/content/images/common_scrapfly-api.svg)
_ScrapFly service does the heavy lifting for you!_

To use the ScrapFly scraping API to avoid blocking, all we have to do is enable the `asp` parameter and select a proxy country:

```python
# standard web scraping code
import httpx
from parsel import Selector

response = httpx.get("some similarweb.com URL")
selector = Selector(response.text)

# in ScrapFly becomes this 👇
from scrapfly import ScrapeConfig, ScrapflyClient

# replaces your HTTP client (httpx in this case)
scrapfly = ScrapflyClient(key="Your ScrapFly API key")

response = scrapfly.scrape(ScrapeConfig(
    url="website URL",
    asp=True, # enable the anti scraping protection to bypass blocking
    proxy_pool="public_residential_pool", # select the residential proxy pool
    country="US", # set the proxy location to a specfic country
    render_js=True # enable rendering JavaScript (like headless browsers) to scrape dynamic content if needed
))

# use the built in Parsel selector
selector = response.selector
# access the HTML content
html = response.scrape_result['content']
```

## FAQ
To wrap up this guide on SimilarWeb web scraping, let's have a look at some frequently asked questions.

#### Are there public APIs for SimilarWeb?
SimilarWeb offers a [subscription-based API](https://developers.similarweb.com/docs/similarweb-web-traffic-api). However, extracting data from SimilarWeb is straightforward, and you can use it to [create your own scraper API](https://scrapfly.io/blog/how-to-turn-web-scrapers-into-data-apis/).

#### Are there alternatives for scraping SimilarWeb?
Yes, you can scrape [Google Trends](https://scrapfly.io/blog/how-to-scrape-google-trends/) and [SEO keywords](https://scrapfly.io/blog/web-scraping-google-seo-keywords/) for similar web traffic insights. For more website scraping tutorials, refer to our [#scrapeguide](https://scrapfly.io/blog/tag/scrapeguide/) blog tag.

## Summary

In this guide, we explained how to scrape SimilarWeb with Python. We started by exploring and navigating the website by **scraping sitemaps**. Then, we went through a step-by-step guide on scraping several SimilarWeb pages for **traffic**, **rankings**, **trending**, and **comparing data**.

We have also explored bypassing web scraping SimilarWeb without getting blocked using ScrapFly and avoiding its validation challenges.
