Hi,

Personally I don't use them and have not seen any negative or positive effects of doing so.

The main reason I don't is, considering Google doesn't use them as a ranking influencer, then I just don't waste time filling them in.  I don't think the time it can take warrant's the reward from any search engine that still looks at them. Plus, I don't like the fact a lazy competitor might take a look to see what my main focus is.

Your time would be better invested focusing elsewhere.

If the keywords tab is already on the site, then how many pages would you need to remove it from? How long would it take? And given the only real reason to remove would be to stop competitors seeing them  - info which they can easily find anyway, is it worth the effort? I'd be inclined to say not.

So, in short - if they are NOT present don't bother adding. If they ARE present, don't waste time removing.

Hope this helps.

Yes, they work ok - best to keep an excel sheet to track who you have emailed. If you dont get a response after a couple of weeks resend. If you still dont get a response then move on.

You can pick some links up, but just make sure you don't spam web-masters and that your requests are relevant.
