One important thing I forgot to mention, but has already been discussed in the PPC forum threads here a couple of times:
A key factor to the CTR numbers is the number of spurious impressions your keywords may be generating. By that, I mean a user may enter something like: "mycommunity mystate pizza, delivery to homes", which might trigger your ad if one of your keyword phrases is: "mycommunity mystate homes" (without the quotes). For a couple of my communities, and for the specific search phrase quoted above, five out of ten of the page one sponsored links are for real estate sites, not pizza delivery stores. Therefore, a large list of negative keywords, mainly at the campaign level, but possibly more at the ad group level as well, is required to keep consumer searches that are NOT really real estate related, from triggering your ads.
You may occasionally see some of these as click-thrus, and if so, your web site stats logs may reveal additional negative keywords that you need to add. But most of the spurious impressions will be for consumer search phrases that you will never see, because AdWords does not track or log every phrase that triggers your ads, and the consumer never clicks your ad, because it is obvious to them that it is not what they are looking for. However, the worst impact of this is that if your ad is not explicit enough, or even if it is, some consumers may still click on your ad, costing you money. They really have no interest in real estate, and may just be curious about why a real estate web site would be listed in Google results for pizza delivery. Maybe they are so bad at selling real estate, they need the extra income!
Be constantly thinking about possible negative key words for all of your search terms, especially as you create new keyword phrases, and you should be able to cut spurious impressions to a minimum, instantly improving your CTR with no significant changes to your ads. My negative keywords list is currently over 1200 words, and growing weekly.
