## Scrape Google Search Results With Go

**[GO](https://go.dev/)**, a procedural programming language was launched by three Google developers, Robert Griesemer, Rob Pike, and Ken Thompson, as an **open-source** programming language in 2009. It is a statically-typed language and has excellent support for concurrency, making it a useful tool for **web scraping**.

GO is designed to be simple to learn, and with the support of concurrency, it has become a fast and robust language.

**[Web scraping](https://serpdog.io/blog/web-scraping-a-complete-guide/)**, data scraping, or data extraction can be defined as the process of extracting a specific piece of data from websites. It can be done manually at a small scale, but the term specifically refers to an automated extraction of data using a scraping bot or a crawler.

In this tutorial, we’ll be scraping **Google Search Results using GO**. We will also discuss why GO can be used as a choice for other languages to scrape Google Search Results.

By the end of the article, you will be able to deal with the complex HTML structure of Google Search Results. You can also leverage or use this knowledge for other web scraping tasks.

## Why Scrape Google Search Results?

Scraping Google Search Results can provide you with a variety of benefits:

**SERP Monitoring** — Scraping Google Search Results allows you to monitor your search rankings on Google, and you can also use this data to improve your positions on the search engine.

**Media Monitoring** — With the help of scraped Google data, you can monitor any negative perspectives that are built among the public to malign your company's image.

**Competition Analysis** — With Google Search Data, you can monitor your competitor tactics and engage in various strategic activities to stay ahead in the market.

## Why GO for scraping Google?

GO Lang, has gained great popularity in recent years due to its quality features:

**Concurrency** — One of the great features offered by Go is support for concurrency, which allows multiple threads to run under a single process, making it possible to scrape multiple pages at once.

**Simple Syntax** — GO language is designed to be easy to learn and read, minimalizing any complexity for web scraping tasks.

**Complied Language** — GO is a compiled language with an excellent garbage setup. That is why it can offer such extreme performance.

## Let’s start scraping Google Search Results With Go

In this section, we will focus on preparing a basic script to scrape the initial ten Google search results, including their title, description, link, etc.

## Set-Up:

If you have not already installed PHP, you can watch these videos for the installation.

 1. [How to set up GO on Windows?](https://youtu.be/kxD8p-aPYzM)

 2. [How to set up GO on MacOS?](https://www.youtube.com/watch?v=fPjcp48dpPM)

### Requirements:

For scraping Google search results with GO, we will install a library:

 1. **[GoQuery ](https://pkg.go.dev/github.com/PuerkitoBio/goquery)**—An library in GO Lang that brings a set of features similar to jQuery and is used for parsing HTML.

You can also install this library in your project folder by running the below command.

     go get github.com/PuerkitoBio/goquery

### Process:

So, I assume that you have set up your GO Lang project folder. We will begin with scraping HTML from the web page URL and then parsing it using GoQuery to extract the required data.

This is the URL we are going to target:

    https://www.google.com/search?q=go+tutorial&gl=us&hl=en

So, let us start creating our scraper by importing the libraries we’ll use later.

    import (
     "fmt"
     "log"
     "net/http"
    
     "github.com/PuerkitoBio/goquery"
    )

Then, we will define a function to get the data from Google Search results.

    func getData() {
     url := "https://www.google.com/search?q=go+tutorials&gl=us&hl=en"
     req, err := http.NewRequest("GET", url, nil)
     if err != nil {
      log.Fatal(err)
     }
    
     req.Header.Set("User-Agent", "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/101.0.4951.54 Safari/537.36")

After initializing the URL, we made a request object using `http.NewRequest()` which takes three parameters, the request type, the target URL, and the request body (nil in our case). If any error occurs while creating the object, we print the error in the terminal using the `log.Fatal()` and exit the function without returning anything.

We also set the header as the User Agent so that our scraping bot can mimic an organic user.

     client := &http.Client{}
     res, err := client.Do(req)
     if err != nil {
      log.Fatal(err)
     }
     defer res.Body.Close()
    
     doc, err := goquery.NewDocumentFromReader(res.Body)
     if err != nil {
      log.Fatal(err)
     }

**Step-by-step explanation:**

 1. In the first line, we created an HTTP client object and called `client.Do()` to make an HTTP request on the server using the req object.

 2. Then, we used the defer to close the response body.

 3. Finally, we called `goquery.NewDocumentFromReader()` with `res.Body` as a parameter to create a Document Object Model.

So, we have completed our scraping part of this program. Let us now move to the parsing part by searching for the required elements from the HTML.

![Inspecting Google Search Results](https://cdn-images-1.medium.com/max/3506/1*dfG8-C68n9MpMJiB-SOz9w.png)

If you inspect the HTML, you will find that every organic result is under the **“g”** tag.

So, looping over this **g** tag will help us to get the data it holds inside it.

     c := 0
     doc.Find("div.g").Each(func(i int, result *goquery.Selection) {

That `c` variable is for displaying the position of the result.

Then, we will extract the tags for the title, link, and description from the HTML.

![Finding tags for the Required Element](https://cdn-images-1.medium.com/max/3494/1*F43Vq5wSgtKm8L5GypK-fA.png)

If you look inside the `div.g` container, you will find that the tag for the title is `h3`, and the tag for the link is `.yuRUbf > a`, and the tag for the description is `.VwiC3b`.

This makes our parser looks like this:

      title := result.Find("h3").First().Text()
      link, _ := result.Find("a").First().Attr("href")
      snippet := result.Find(".VwiC3b").First().Text()
    
      fmt.Printf("Title: %s\n", title)
      fmt.Printf("Link: %s\n", link)
      fmt.Printf("Snippet: %s\n", snippet)
      fmt.Printf("Position: %d\n", c+1)
      fmt.Println()
    
      c++
     })
    }

Then, we will call the `getData()` function to execute our scraper.

    func main() {
     getData()
    }

Run this code in your terminal. You will get the results like this:

Congratulations🎉🎉!!! You have successfully created a scraper to extract Google Search Results.

But, this solution can result in an IP block if you use it for scraping large amounts of data from the Google search engine. Instead, you can use several **[Google Scraper APIs](https://serpdog.io/)** available in the market, which uses a large pool of residential and data center proxies to bypass anti-scraping mechanisms implemented by Google.
