Google is the behemoth of search engines, the plateau we aspire to, and the chagrin of many a Webmaster and marketer. If they love your website, you will in turn grow to love the masses of traffic they send your way. In contrast, if they deem your site to be of little or no value then you'll struggle to fill the aching void in your Internet marketing. OK, so that might be a little over the top but to the battle hardened SEO a lot of it will probably ring true and they are certainly the biggest and most popular of the current search engines.
