Web Crawling :

Web Crawling is the process of search engines combing through web pages in order to properly index them. These “web crawlers” systematically crawl pages and look at the keywords contained on the page, the kind of content, all the links on the page, and then returns that information to the search engine’s server for indexing. Then they follow all the hyperlinks on the website to get to other websites. When a search engine user enters a query, the search engine will go to its index and return the most relevant search results based on the keywords in the search term. Web crawling is an automated process and provides quick, up to date data.

Why is Web Crawling important:

Web crawling makes it easier for search engines to return the most relevant results to users after they enter a search query. The “crawlers” will scour a website and index each web page accordingly. Optimizing a web page with strong keywords and great content will help web crawlers index that page in a way that will allow it to be shown to its target audience. Web programmers can instruct a web crawler to ignore and not index a specific page.
