Search engines send spiders to crawl your website. They do this in just a split second....in the time it takes from you to press search to the time it takes your results to show up on the screen. They are looking to find the most relevant websites for the search that was submitted. This is why you must include keywords and other information so they have that information to find. This is a cool link where you can see what the spiders see on your website while they are working! Let us know if we can help you with your SEO.
