Our client is wondering whether their ads are getting a better CTR than those of their competitors. Is there a way to infer this, even vaguely?
Who has the best CTR depends who has the best targeted keywords and best ad copy. If you are confident you have done this for your client then they will have the best CTR.
Also worth pointing out that it is converions that count not CTR. You can buy clicks with high max bids and misleading copy but it won't get you sales and will lose you money.
What exactly is that interest bar? I'm assuming it's proportional to CTR.
Correct!
The 'Interest Bar' was originally meant to me a graphic representation of the CTR of the keyword that was searched on. A full 'Interest Bar' meant the CTR was @ 1% CTR or above.
Interestingly, it was removed due to advertiser feedback, some of which was collected on this very forum, as I recall. :)
It is fascinating to see that at least some may be wishing for it's return!
