Has anyone had any problems signing up with http://sponsoredlistings.ask.com and advertising?
I applied 2 times in the past week and never heard back from them, does anyone know how I can get approved?
Hmmm Ask has only small market share of search results.
But maybe you can look at their statistic, look which people use it so you can optimize whether you will use it or not.
After that, are you sure you want to?
I wouldn't trust them.
There are too many other ad networks.
Ask is certainly a small search player but they are still in business. If you really want in I would email them and ask, it's possible they have a manual process (they did in years past) and simply haven't gotten to you yet.
