Something you may have been overlooking that helps lots.
I have a lot of listings that are well ranked in the organic SERPS and thought, hey I know I can not measure CTR on organic but it must really suck, and it must have....
I changed up my title tag and description for one of my #1 ranked results. I left in the SEO mandatory stuff but really livened it up with some good copy. And hit it with my pinger last night. It got crawled straight away and my change was indexed.
As a result my traffic has doubled!
If you think about it when you write a PPC add your mission is to get that sucker clicked as often as possible. Organic is no different although for some reason since I was not 'paying' for it I never thought about them in the same way. In reality I paid more because of all of my link building efforts, etc.
Anyway....
Basic stuff that I should have known (well I did but did not implement it) but thought some of you may have been neglecting this as I was...
JUST >>> $1 >>> ONE BUCK >>> ONE DOLLAR
