A web crawleralso known as a spider or web bot, is a software program that systematically searches the World Wide Web to index websites and collect information. This process is the first step in the functioning of search engines such as Google, Bing or alternatives to these.
Crawlers follow links on web pages, read the content and save a copy on the servers of the respective search engine. The created copy of the scanned content is stored in an index. This is ultimately a huge database whose contents are used by search engine algorithms to generate search results from all the recorded URLs of all websites.
A deep understanding of crawlers is essential for search engine optimization. Whether a URL is shown at number 1 in the SERPs depends on indexing management. This involves deliberately guiding the web crawler to new and relevant content. Or strategically used indexing management can ensure that content remains hidden from search engines. There is a cross-domain option here es : the Robots.txt file. This es is a file that defines exclusion criteria for search engines. This definition covers the entire domain.
A second solution for indexing management is the robots meta tag. Here, the web crawler is instructed at URL level to crawl and index URLs and their registered links. Accessibility can just as easily be denied. Well-managed crawling management and indexing management makes it easier for es bots to find relevant pages, improves website performance and helps to increase the ranking in search results.
In addition, pages that are difficult for crawlers to access, for example due to poor internal linking or deep page hierarchies, may not perform well in search engines. Therefore, the structure and navigation of the website is crucial to ensure that web bots can reach and index all important pages. Optimizations in this area help to improve the visibility and findability of a website in search engines, which in turn can lead to increased traffic and ultimately higher conversions.
