I was told a bunch of my keywords had to be inserted into the creatives before they would be approved recently by Yahoo!

Posted about it over at the Search Engine Watch forums and it seems I am not the only one.

The hardest thing to work out is what determines which words have to be inserted. Is it where the CTR is not as high as the average for the word? Is it where the majority of advertisers for the word are doing it and have high CTRs?

Whatever the criteria it is arbitrary right now and frustrating.
