Did you ever wonder how google or yahoo finds your site content well the idea is pretty simple lets take google as an example now Mr google have something called googlebot which is a software used by google to crawl the world wide web and collect information it’s also known as spider, this spider can find your site from link to your site if you have no inlinks you kinda have to let google know “hey i’m here’ and you do this by submitting your to url to google indexing service of course every search engine got it’s own url adder the only catch is google crawlers can read only text not images not flash (however you can add metadata to your images ) that’s why most of the pages rank high on search engines includes more text content so lets make it simple if you can’t read it google can’t, that is why i recommend adding erotic stories or daily diary to your blog not only some sexy images
