Did you know that there are spiders crawling the Internet? Web spiders, also known as ants, bots, and web crawlers, browse Internet sites in an orderly way. As they crawl, they notice things like words and links, and build up a gigantic table of contents for the Internet.
Search engines employ web spiders to find out what’s out there. Web spiders will have an easier time finding your site–and telling Google®, Yahoo!®, Bing®, and other search engines that your site exists–if your site contains relevant, well-regarded links. Incorporating a lot of high-quality links helps web spiders find and identify your site, and therefore helps your site achieve higher rankings in search-engine resolts.
