Has this been bringing me in less clicks or more clicks?
Im thinking it is bringing me more clicks because of showing ads with a higher ctr. Thus the ads will recieve more clicks.
Unchecking "optimize adserving for my ads", will that show more ads at one time than before.
Im thinking I should leave this checked. What do you think?
When I'm sure they all have a decent CTR I turn it off and measure which one has the best results. Best results are for me the best combination of CTR and conversion rates.
In the end none of my campaigns end up with optimization on.
We generally leave it off and then review CTR for poor performing creatives to delete. In the majority of cases we only have one ad showing, and A/B test through the backend, at least then your sales results are consistent with the same message.
Gets horribly complicated if you have 20 keywords, 5 ads and 3 landing pages to work out what works best...... and experience of handling campaigns counts a lot for not making mistakes.
The 'Automatically optimize ad serving for my ads' does nothing at all unless an advertiser has more than one ad in the same Ad Group.
It has no affect at all on different ads in different Ad Groups, or different ads in different campaigns.
Pure and simple, it only affects the way multiple ads in the same Ad Group are rotated.

The tons of impressions you can get from AdSense can muddle your ad CTRs for G/Search stats, and those are the ones for most campaigns that you want to do well. Once you understand how the search vs content CTRs play out, then turning ad optimization on can be very useful.
