do you ever think that google are trying to analyse too much?
i mean, most people can tell within 5 seconds whether a site is good or rubbish, and they don't take into account a tenth of the stuff that google do.
in my mind, a good site is good, and who cares what percentage of words you can see above the fold. if it's good im not going to dump it just because its 15% instead of 10.
sometimes i think of google as a crazy cook. everytime they come across a new vegetable they have to chop it up and add it to the recipe. they cant help themselves. every bit of food gets a pinch or two in the bowl, hoping that it's going to make it taste a little better.
