Whats the poll..?? What is unacceptable for your click through rate..?? I hope this poll isnt aimed at Namedrive and is more rhetorical than judgemental..
99% of CTR depends upon your domain names and your choice of keyword/s. The only part where Namedrive come in is with the design. Now, most really like the new skins, so theres their bit taken care of.
If people wanna keep swapping and moving domains from here to there to there to here - let me bring you up to speed with PPC. Most of the big PPC companies take their PPC feed from google. With the exception of Fabulous and gambling domains (which i believe is not Google fed), most of the PPC companies will pay you a very very similar percentage of the click. However, google's "smartpricing" tool is now heavily reducing the amount you get in PPC. Crap clicks from parking pages = reduced advertiser costs = less money to you.
A sad yet inevitable step in the PPC industry im afraid.
