Hey. Hopefully you don't mind me chiming in here. Here are some of the differences/stats for our software(whatrunswhere):
- We started collecting data in late 2009, so we have a huge amount of archived data from a lot of different ad networks. Most competitors started off Google only, so their archive data for non-Google ad networks is quite limited.
- We have not only mobile web, but mobile android. We scrape ads that are appearing in over 20,000 different Android apps..something no one else can claim at present. The basic package that includes mobile is only $50 more than our normal package.
- We currently have >100 different ad networks classified for Web display, and ~120 classified for mobile...but even then, our technology can recognize banner ads that we don't know the ad network of. So while we have those number classified, we'll show you ones from ad servers before anyone else. If a network appears while we're asleep, it will be in the software by the next day. The total number of adservers we've gotten ads from is well into the thousands. We're also classifying about 10-20 new ad networks every week right now.
- We have a 1 page-load, 1 impression philosophy: we load the pages as the user does and only store the ads that showed up during that page load Some competitors(who I will not name directly) reload iframes over and over again, rendering their data almost completely worthless. If the Javascript on the homepage is splitting up the impressions between different ad sources, reloading an iframe will just show you the same one you saw the first time.
- We have in-house staff that deals with all support, nothing is outsourced. If you're using our software, the live chat will put you on with someone who actually knows the software and is physically present in one of our two offices.
- We've been scraping international much longer than anyone else - we were the first to go international and still have the best spread of international data in both mobile and traditional web.
If you've got any questions, I'd be more than happy to answer. There weren't too many answers in this thread so I figured I'd reply. There's a lot of differences, I could probably tell you more if I knew more about your priorities.
