Lately I have been looking at many different categories in a search to see what people are using as there meta keywords and find many of the top sites have no meta keywords listed. They are pretty easy to look for since yahoo lets you see the page source where you can see the html code and can look for the meta data keywords.
I am wondering why, is this something fairly new and does it still mater and should we still do it on our sites. At least for the sites I looked at it doesn't seem to mater as they were all in the top 5 of page one on yahoo and when checking the same sites on google they were in just about the same positions there as well. Any thoughts.
