What is the Indexing / Spider Process?
Search engine spiders are used to automate the indexing of websites
The spider locates home page and reads the header page content and finds and follows links
Data is returned to search engine database and a list made of the words found and web pages they where found on. The search engine then indexes the web pages.
When you search for something the search engine looks through this index and returns the websites found on its list
The indexing system consists of key words and links to websites furthermore search engines make use of the meta tags developers implement into their websites (info we cannot see)
The act of spider-crawling changes over the years. Previously a spider would crawl the whole web before the pages were indexed by google, it could take over a month to crawl the whole web before the indexing would start.
