There's one thing that you still see way too much of and that's keywords crammed into websites with no regard for the flow or readability or the content. You might get the search engines to notice you that way, but you'll get people clicking off your site if the content reads badly. Remember that keywords and their phrases need to be carefully placed so that they blend in. A good yardstick that seems to work is once every 100 words. Web copy needs to be written by professionals.
