We've been looking at whether we should continue to enter keywords in the keyword metadata field of our CMS. Apparently, Google is pretty much ignoring that field in search ranking. Below is a quote from Google, and a link to the blog the quote is pulled from.
We also use a Google search appliance for our site search. You'll see from the comments on that Google blog that not everyone agrees that the keyword metadata field should be abandoned and that keyword entry in the field DOES appear to influence page ranking in spite of Google's declaration. I'd be interested in your thoughts and grateful for your insights. Thanks!
Q: Does Google ever use the "keywords" meta tag in its web search ranking?
A: In a word, no. Google does sell a Google Search Appliance, and that product has the ability to match meta tags, which could include the keywords meta tag. But that's an enterprise search appliance that is completely separate from our main web search. Our web search (the well-known search at Google.com that hundreds of millions of people use each day) disregards keyword metatags completely. They simply don't have any effect in our search ranking at present.
