I'd like to create individual ad campaigns on Adwords pointing to these various homes. As the number of searches for these keywords is very low (less than 20 per day) it is important that the ad has Top-of-Page placement.
I'm not concerned about the quality score of the land page as it will be 100% keyword optimized to match the search query when the user types in the address of the house. As I said, the landing pages will have video, photos, a text blog post, maps and more. They also have no ads.
I've read, though, that Google gives high weight to the CTR when determining if your ad can get boosted to the Top-of-Page. If there isn't enough traffic for the keyword, then will I never be able to meet the CTR threshold?
I mean, I might have a 5% CTR on the right side of the page, but if there are only 10 searches p/day then it will take 10 days to figure that out. Also, might not Google refuse to make a decision on whether to give Top-of-Page boost if there are less than 1,000 impressions? If so, the buzz of a new home on the market may fade and searches drop before Big G can even make a determination on whether to give Top-of-Page rank.
