Crawlers are the behind-the-scenes workers in the world of search engine optimization. But what are they, exactly? And how can they improve your site’s performance in the SERPs?

SEO is the process of increasing visibility in search engine results pages by improving the rank of a website or a web page in the organic search results. Put simply, it’s all about making your content more visible in search engines. And there are many tools that you can use to do this. One way is using crawlers that index your site with new content automatically, which means Google and other sites will be able to find them much faster than they would without this tool.
Web crawler is a program which accesses the World Wide Web (WWW) in a methodical manner. It starts at one specific point on the web and follows every hyperlink, making note of where it’s going. The crawler then revisits each page every few days or weeks. This process is known as crawling because the program is basically moving from site to site like an insect would crawl across the ground. It’s important to know that search engine crawlers do not get all the information they need from links alone. That’s why they also index content found in images, video files, PDFs and other formats.
