De ce să nu îl folosești pentru Google?
Recently we received some questions about how Google uses (or more accurately, doesn’t use) the “keywords” meta tag in ranking web search results. Suppose you have two website owners, Alice and Bob. Alice runs a company called AliceCo and Bob runs BobCo. One day while looking at Bob’s site, Alice notices that Bob has copied some of the words that she uses in her “keywords” meta tag. Even more interesting, Bob has added the words “AliceCo” to his “keywords” meta tag. Should Alice be concerned?
At least for Google’s web search results currently (September 2009), the answer is no. Google doesn’t use the “keywords” meta tag in our web search ranking.

De ce să nu îl folosești pentru Bing?
SEO for Bing – a discussion with Bing’s Duane Forrester – Bing Search Engine News forum at WebmasterWorld – WebmasterWorld: I’ll make this statement: meta keywords is a signal. One of roughly a thousand we analyze.
Getting it right is a nice perk for us, but won’t rock your world. Abusing meta keywords can hurt you.
Here’s the other problem – Meta keywords has been used as a negative ranking signal, and probably still is to some degree. In other words, you might not gain much or anything from using it, but if you spam it, you could get devalued. My gut feeling is that the negative signal is much, much stronger than the positive one, and even Google may still use it as a negative signal. I’m certain that Yahoo/Bing has used it as a negative signal (not sure if they still do).
