In this video Matt Cutts, of the Google anti-spam team, talks about why Google actually talks about SEO. It is an interesting question. Why does Google actually help webmasters and SEO resellers with SEO. It does seem like a cat-and-mouse situation. But as Matt / Google explains. The better the real Internet is, the people will use Google to find things. So there is really a love-love-hate-hate relationship between Google and the SEO reseller community. Give this a watch and decide for yourself. Interesting stuff.
