Ad stats, and why people make DLC. November 4, 2010 cliffski Sooo. I managed to keep my grubby paws from editing my ad campaigns for 30 seconds. I blogged a few days ago about how I took the top 25 sites for ROI (return-on-investment) and confined the Gratuitous Space Battles ad campaign to just them. Here is the results. Over almost 6 days the impressions for the banners totalled 678,000. The clicks were 3,636 and the average cost per click was a whopping £0.10 (roughly $0.16). That cost me £366.94. Over the same period the income from gratuitous space battles sales was a total of $1,095.71, or roughly £684. So in a crude sense, I spent 366 and got 684 back. In theory, a pretty good deal. However, I would have got some of those sales anyway, through word-of-mouth, and through reviews and so on. Plus some of them are people buying expansion packs for already bought copies. On the other hand, some of the visitors would have bought the game from impulse or steam or elsewhere, so I get that money too. Plus a bunch of them may buy the game in a week, or even in six months. It’s hard to tell. If you look at it as £318 for 6 days, that’s nothing very exciting at all. Thankfully I have other games on sale, otherwise I’d be scared :D. For comparison, I looked at the month of september too. $9,203 sales. £2,532 ads (roughly $4,051) . That is heavily skewed by the release of the Nomads expansion pack. On the surface, my recent 6 day ad-driven experiment was a ROI of 186% and september gave me a ROI of 227%. So one of two things has happened. Either the new ‘let google pick them’ strategy is not as effective as I thought it would be, or in fact adverts are just not in any way as good at generating income as new expansion packs. I think it’s probably the latter. Don’t forget that the expansion packs will continue to sell for a few more months, and also generate extra income from sites like impulse and steam (if they actually add the nomads :D). I know some people hate games that keep releasing DLC, but programmers have to eat, and if I’m honest, the smart thing to do (from a business POV) is to keep doing them. I don’t think I will though, I think the campaign is the last one. Out of interest, has anyone here ever seen a GSB ad? where did you see it?
