i'm confused by something. it's reccommended that you not repeat your keywords in the meta tags because search engines penalize you. BUT there's also a reccommendation that you should put different versions of words in Caps, small case and proper case. so my company has a product, called MATLAB. a previous webmaster listed our keywords MATLAB, matlab, etc., etc.... should i remove the duplicate or not?
It's better to limit things to just a few targeted keywords rather than trying to stuff as many as you can in. Stick to 7-8 keywords targeted to the page content and make different pages target different keywords.
