As someone who spends a lot of time with the PPCs, there are a few features that would be great for further optimizing campaigns, and these features are mostly about ad control. PPC is one of the few (if not the only) ad place where a publisher is not in complete control - so here's my list of what I'd like to see...
1. Ad CTR rates for Google only as this is what determines ad placement.
2. The ability to show ads on only partner sites and not Google.
With the ability to regional target on Google, and not on partner sites, disabling a national campaign on Google for regional ads, yet keeping the national for partners would give us more control.
3. AdSense Only Campain.
AdSense searches are much different than Google ones. If Google is in doubt, it uses a more common keyword, and not more specific ones. This has led to many terms not being properly advertised for on AdSense, as those common terms people would rack up thousands of impressions a day on Google, and yet less than a thousand on AdSense sites. I would like to make a campaign strictly for AdSense which is not shown anywhere else as it's such a different type of market.
4. Allow advertisers to pay in advance.
Many people use debit cards for PPC so their cards don't get out of control, or so accountants have some control over Ad dollars.
5. Suggestion for the Beta Regional Ads - Allow more than 5 groups per campaign. If you want to target all of NY except NYC, you need to make 2 campaigns as NY has more than 5 areas.
6. Higher cap on max campaigns.
With the regional campaign, I'm also having issues with the max number of campaigns allowed (25). We're in 21 states, and I'd like to see the numbers per state (plus different ads preform completely differently in various states), so I want one regional campaign per state. Combined with my other national ads, I don't have enough campaign space to accomplish this.
I think this is my Google wish list, at least for today...
