What makes you like a website? The colors, photos, look and feel of the site? The motion, the videos, or a fancy opening page? The things that appeal to humans do not appeal to search engine spiders.
SEO spiders refers to the technology behind indexing websites. If the spiders like your site, it will rank well in Google, Yahoo, and other search engines. If the spiders don’t like your site, in competitive markets, it will get buried. To spiders, words are like big, fat flies. SEO spiders’ mouths water at the thought of a website with a ton of content on it.
