There seems to be a lot of confusion about how to (or whether to) optomize sites currently. I know I am confused and a little scared. I have clients that are doing much worse for their money keywords and I'm not quite sure what to do. I was scared to go get links because that would appear to be a sign of someone optomizing a site. I was scared to optomize because, well, that too would appear to be a sign of someone optomizing a site. All my new pages are now called either welcome or home. Okay, so I'm kidding. There is one thing that will hold steady, whatever happens with G. If you make your sites well for the user, whatever happens with the SE's will be temporary. While things may be cloudy now, all the basics still apply. Make your site's content interesting and unique. Base your inbound links on traffic (I consider added value to SE traffic here) and your outbound links on your visitor. Make your navigation spider friendly as well as user friendly. Now you do everything you can to get traffic, keep traffic, sell, whatever, without damaging the strong base you've created for search engines. It has become very cloudy as to how we should optomize for Google. "Which is the way he wants it. Well, he gets it! 'n I don't like it any more than you men."
I should add that the quote referenced above is from Guns n Roses' Civil War. I found the exact phrasing by searching on Google.
After 220,000 miles my Subaru is definitely broke(n). The stereo still works and it still gets us there so noone really notices. It doesn't mean I wouldn't drive something else if it became available though.
