My company has a competitor that every few months publishes a blog posting "Ways people find us" and then they list what they call "interesting keywords and phrases people used to find them." I'm assuming they are going through their web server logs to pull these keywords and phrases, but who knows? What this appears to be doing is bumping up their search scores for terms that already worked to find their site (assuming they pulled the list from their logs). This part sounds appealing to me but, many of these terms include competitor names which now allows them to ride on the coattails of their competitors.
To me, I don't have an issue with a vendor using a competitors name in legitimate content on their site but I question whether or not reposting search keywords and phrases is "legitimate content." Like the title asks, is this is a legitimate SEO tactic or a slimy trick?
