What are Search Engine Crawlers?
an end-user types in a keyword or phrase in a search engine, the search engine will deploy an automated script or program that will scan or crawl through a large database of Internet pages. When the crawler finds the data that it is seeking, the search engine will create an index and display the most relevant results to the end-user. Crawlers are also alternatively known as automatic indexers, bots, web robots, and spiders.
A search engine crawlers will read the visible text, hyperlinks, and tags and metadata that are facilitated in the HTML (HyperText Markup Language) framework of a webpage. As search engines increase in sophistication, search engines have the capabilities to determine what the site is and whether it is relevant to what the end-user is seeking.
