Is there a way to find out competition for certain keywords among publishers?
It's a general rule for publishers to find keywords with low competition among publishers. I searched multiple forums and found that many posters recommend using Google's keyword tool to find low competition keywords. It appears to be wrong. Google's keyword tool is an advertiser tool. Low competition among advertisers is not good a sign for a publisher.
Is there information on competition between publishers on certain keywords? I know, there are keyword tools like Wordtracker, Wordstream, Trillium, etc available. They do provide information on competition. How do I know that this is publisher information data? They all probably scoop up Google's information anyway, and Google's competition information is available for advertisers only.
Your help is much appreciated in advance.
