3 Reasons Why You Need to Develop a Web Scraper/Crawler?

 



If you have somewhat relevancy to the web development, you must have listened about the term ‘Web Crawler’. There are several other names like web spider or search engine bot that people use to define it. Today we’ll discover a bit further about web crawlers and their significance that can help your business cause to gain its motive.

Before making any further progress on this topic, there are some basics that we should need to understand. The first point is to understand what is a web crawler and how it works. Apart from all the critical points to address while developing a web app, we should also know the importance of web crawlers in specifically web development.

What is a Web Crawler?

You must be thinking that how web crawlers relate to web development when there is nothing similar to its development process. For example, the majority of web scrapers lack UI/UX and human interaction. The value and ranking of a web app depend a lot on its content optimization apart from its interface. A web crawler, in the case of a search engine, crawls through the World Wide Web and index pages, hence ranking the pages as per the target site’s SEO.

 

A Web crawler/scraper is an automated software program designed to perform a predefined set of tasks without human intervention. Powered with a multi-threading approach, it speeds up the execution while ensuring 0 errors. Common examples of Web scrapers are Search engine indexing bots, website information scrappers, automated content posting software in the form of chatbots, and product information scraper. 

How it Works?

SEO has an important role to rank any website higher and mostly WordPress websites are dependent on it. Now, to make your website optimized, you just need to understand the working structure of a web crawler. Continuing with the example of a search engine sites ranking crawler:

 

●     There are chances that the web crawler might have gone through a site. If it hasn’t crawled it during the search, then it will reach it by following the link from another page. In some cases, the website’s owner submits a sitemap to crawl its URL by the web bot.

●     Now the search engine provides the list of web addresses to its web crawler for checking as seeds. Through these URLs, the web bots explore every URL on the list and their linked pages by using different site maps.

●     After visiting all the seeds on their list, the web crawlers render the content and include it in the index. The index is the space where a search engine stores all the data on the internet.

●     In some cases, you can also block a web crawler from rendering your website by robots.txt file with specific rules or your HTTP can contain a status that shows that the page doesn't exist.

●     Meanwhile, the robot.txt file is a pathway of communication with a web crawler. A web bot always checks for this specific file before crawling any web page.
