A Search Engine Watch Forums member asks if he's been given solid advice: basically, he was told that he should delete his highest-performing keywords from his current Google AdWords group and put them in a group of its own.
I've never heard of such a thing myself, but AdWordsAdvisor confirms that this is not the way to go about dealing with high-performing keywords. In fact, AdWordsAdvisor says that you shouldn't relocate any high-performing keywords; just delete the poor performers or give them another group dedicated to trying to optimize them and help them perform better.
I would actually suggest the opposite approach - which would be to keep your best performing keywords right where they are, and either:
* get rid of low performing keywords altogether, or
* create new (and very carefully targeted) ad groups for them - to give them their best chance of performing better.
When I say a 'very carefully targeted ad group' I mean a short list of keywords which are all about the same thing and a well written ad which is also about that exact same thing.
This, as opposed to the rumor that's been circulating, is solid advice.
