The one Adwords resource no serious online marketer should be without...
I know a thing or two about keyword research and Adwords myself (he said modestly - but I did after all write the Keyword Master's Course). But the collective comments, wisdom and experience of the hundreds of Adwords Professionals in this little corner of the web are a nugget of pure gold.
And something else.
I'm not an affiliate - and I get no reward for recommending them.
So who are they?
It's called Adword Mentor and it is a subscription forum run by Chris Carpenter and Jeremy Wilson. It's well worth it, because the users share genuine insights and experience about their collective experience - and it's always up to date as the forum is a lightning rod for discovering changes at Google.
Highly recommended.
