This tutorial will teach the differences between web crawling and web scraping. We will also explore web scraping and web crawling in detail so that you can understand the distinctions between them.

## What is Web Scraping?

Web Scraping is the process of extraction of data from websites. It can be done manually or using any automated tool to collect the data quickly. It is generally helpful when a desired website does not offer any official API or is expensive to be used by developers.

The gathered data can be used for various purposes such as monitoring, research, and analysis according to the specific demands of the businesses. This helps companies to make data-driven decisions to remain competitive in the market.

## Uses of web scraping

Web Scraping helps developers and businesses in a variety of ways:

**Market Research:** Web Scraping allows businesses to identify future trends and patterns, understand customer sentiments, and gain a more profound knowledge of market demand, enabling them to align their products or services according to consumer interest.

**Competitor Analysis:** In a world of fierce competition, web scraping allows businesses to gather important insights into the strategies followed by their competitors, allowing them to identify the strengths and weaknesses of their competitors and gain a competitive edge in the market.

**Product Research:** Product Research is essential when launching a new product. Web Scraping enables businesses to get a sneak peek into the products offered by their competitors. By analyzing the pricing model, ratings, and customer reviews they can gather insights into customer preferences and identify gaps in the market to develop competitive product strategies.

## What is Web Crawling?

Web Crawling can be defined as the process of systematically analyzing the gathered URLs and checking their website content, commonly used in applications such as search engines, price comparison, business intelligence, and more.

This technique is widely used on a large scale by search engines like Google, Bing, Yandex, etc. Additionally, it is instrumental for SEO analysis as it enables businesses to collect data about their backlinks, website rankings, and much more.

## Uses of Web Crawling

Web Crawling helps developers and businesses in a variety of ways:

**Enormous Data** — Web Crawlers can collect large amounts of information from the internet, making them powerful tools for data gathering and analysis.

**SEO** — Search Engines like Google use this data to index web pages and understand the website structure, content, and keywords.

**Tracking** — To track anything, such as product pricing or website ranking, you can use a web crawling technique for faster access to information.

## What is the difference?

From the above information, we can conclude that both entities deal with a specific type of data collection but with some major differences.

Web Crawling mainly deals with the indexing of web pages. You don’t have any idea about the URLs and domains you are trying to crawl. And that’s why you crawl them to understand these webpages.

On the other hand, web scraping’s only purpose is to gather a specific set of data from the target website. The scraped data is then cleaned and processed into a structured format, making it easy to access. It finds its use cases in a variety of purposes like price monitoring, rank tracking, media monitoring, etc.

## Best Practices

**Use Proxy Servers —** It is essential to use proxy servers so that they can act as an intermediate between you and the target website, which also protects your identity. Proxy Servers usually have access to large amounts of IPs which you can rotate and extract information from a target website at scale.

**Rate Limit** — Respect the website server. Apply the rate limit so that your target website doesn’t overload and causes disruption to its performance and services.

**User-Agents as headers** — User-Agents can be utilized to make your bot mimic an organic user, reducing the risk of getting blocked while extracting data from target websites.

**Crawl delays** — Avoid overloading the website server with frequent requests. Add delays in your crawler and respect the website terms of service, robots.txt, and privacy regulations.

## Conclusion

In a nutshell, web crawling can be defined as the indexing of URLs, which is a lot simpler as you only have to deal with the URLs. On the other hand, web scraping involves extracting a specific set of data or information to help businesses in their data-driven decisions.
