Now I word this question carefully:- Is the META Keyword Tag Worth The Effort in 2010? I know Google discounts the META keyword tag altogether:- http://googlewebmastercentral.blogspot.com/2009/09/google-does-not-use-keywords-meta-tag.html When I've asked this before, most people reply "you might as well use it". But if you're going to use it correctly, then it's quite a bit of effort if you consider large e-commerce sites (largely my market, I'm a web developer). ....so is it worth the effort (and it does require effort to do it right) to properly use the META Keyword tag? Or is that time better spent on other areas of SEO? Think about a website where you're about to add 1000 products. Would it be worth the time and effort to write out individual keywords for each and every product, for each page's META Keyword tag? Personally I think the time is better spent on visual content and backlinks (and of course, TITLE, META description, Headline tags, friendly URLs etc) - but I'm hoping someone can have a compelling argument for META keywords - interested in your reasoning. Remember that time is a finite resource and utilising the META keyword tag properly over hundreds or thousands of pages is quite a job.
for large e-commerce sites, the most work-efficient method is to just include whatever product it's showing in the keywords tag. for instance, say a page drilled down 4-5 pages ends at a DVD movie. you could dynamically have it so the meta keywords content would be: "dvds & videos, movies, action & adventure movies, dvd title, yourbrand.com" or something similar. developers can easily do this.
Well if you are doing large ecommerce site, then you should have a way of dynamically generating the meta keywords tag. Therei s simply no point in trying to write all those meta keywords by hand. So I would suggest you find a way to dynamically generate keywords from page titles. That way, you got the best of both worlds - if a search engine ignores meta keywords, then fine, if it takes into account, then you still have meta keywords to go by.
checkout seopitfall.com. they just did a post about which onsite factors affect search engines and ranked them from highest to lowest. meta keywords ranked for yahoo but not for google.
i'm not more focus on mata keywords each and every time any project i have so i made only title tags and some other SEO techniques
