If you’re running a website, it’s important to understand how crawlers work and what you can do to make the most of them. In this article, we’ll discuss everything you need to know about website crawlers and how SEO PowerSuite’s SEO Reporting Software ensures that the engine “likes” your website. So whether you’re just getting started with websites or looking for ways to stay ahead of the competition, this article is for you!

What Exactly Is A Website Crawler?

A web crawler, also known as a web spider, is a program that crawls through a list of websites to collect information about each site. They are mainly used by search engines to index web pages. A web crawler begins its work with the assigned list of URLs or the seed list. As the crawler visits these websites, it identifies all the hyperlinks in them and adds them to its list of URLs, called the queue. The crawler continues visiting new websites and extracting their content until it has visited all the URLs on its list. 

There are two major types of web crawlers:

  • Depth-first web crawlers follow links depth-first, meaning they will crawl all the links on the first page they visit before moving on to the next page. 
  • Breadth-first web crawlers crawl links breadth-first, meaning they will crawl all the links on every page before moving on to the next page. 

Technology Web crawlers can be further customized by adding rules that tell them which pages to index and which ones to ignore. For example, a web crawler might be configured to index only pages that contain the word “crawler” in them. 

More On How It Works: Principles And Use Cases

Very often, a web crawler works in tandem with a web scraper. The latter is similar to a web crawler, but it focuses on specific data instead of indexing the entire website. Typically, web scrapers are used to extract data from online databases or forums. For example, a web scraper could be used to gather contact information from an online directory. Web scrapers are also sometimes used to bypass paywalls or other types of content restrictions.

Web crawlers are used across multiple industries and for different purposes. Here are a few examples of their typical use cases:

  • E-commerce: E-commerce websites use web crawlers to gather product information from other websites and create a central database. This allows e-commerce websites to provide up-to-date product information to their users.
  • Social media: Social media platforms use web crawlers to keep track of new content and ensure that their users have the most relevant information. 
  • Real estate: Real estate websites use web crawlers to collect data on prices, square footage, and other features of properties. This allows potential home buyers to easily compare different properties and make an informed decision.
