About Spiders and Internal Links
Search Engine Visibility provides several options for you to assist search engine spiders and crawlers in navigating your Website with ease. Having working links throughout your Website is essential to successful search engine optimization.
Spiders representing the Internet's search engines regularly crawl the World Wide Web to look for websites and other content to add to the search engines' databases. They follow the hyperlinks that connect websites on the Internet.
Due to their very nature, spiders are crippled when they have no links to follow. If your website has broken or no internal links a spider will likely not go beyond the first link. If your Website contains external links, the spider might follow those and leave the Website behind.
If, however, all the Web pages on your Website are linked to each other with functional hyperlinks, a visiting spider is able to visit every nook and cranny of the Website.
