Advertising ROI, Day Eight
Tuesday, June 30th, 2009Well, it’s been a week and a day. I know I promised daily updates, but yeah.
Here’s the good news: the Google AdSense campaign finally kicked it. It started delivering ads on 6/25 and has been running at full tilt since. I can only assume that, since this was an image ad, the Google Robotic Brain had been holding it until a human being could review it and approve it. I didn’t see any kind of note to that effect, though, which is annoying, if that’s what happened. I didn’t do anything else, make any changes to the campaign or any of that, so I can’t imagine what else the problem could have been.
But no matter. The ads are running now. Here’s the data:

Note: click-through ratio and cost-per-click are based on the click numbers provided by the ad platform, not on our internally tracked numbers. Our own internal click-through count has been consistently higher than any of the ad platforms’ numbers. I have a new theory. Some of the extras are caused by the ad server itself (Google’s, or PW’s, or Facebook’s) double-checking the URL to make sure that the page it’s supposed to be linking to is still in existence. I arrive at this theory because, even before Google started showing the ads, there were exactly two “hits” a day to the tracking URL I used when I set this campaign up. That had to have been Google. Our internal tracking simply counts the number of times a particular URL is hit, and I used a different unique URL for each ad. People could also, possibly, be passing the URL’s around to their friends. This is unlikely, but would be a pleasant reason to have your stats screwed up, wouldn’t it? Either way, I am going to stop reporting our internal click-tracking numbers from now on, and just go with the ones provided by the ad networks. If our numbers had been consistently lower, or if they’d been higher for some networks, and lower for others, I would still care about them. But I don’t.
ComicSpace blog reader (and creator of Calamities of Nature) Tony Piro made some helpful suggestions in the comments of the Day Three post. In particular, he reminded me that the people commenting on the blog can be helpful resources, who may be able to point the way to improving the performance of the campaigns, but only if I share more information about the campaigns themselves. So here’s the banner we’re running through Google and PW:

And here’s the ad that’s running on Facebook:

One of Tony’s suggestions was that we might get more clicks if the ads weren’t obviously for merchandise — and that once somebody clicked, he or she might actually poke around and look at stuff and maybe buy something. We considered that before starting this campaign, but decided to be very, very upfront about the t-shirtiness of the thing you’re clicking on, not out of any benevolent goodwill or anything, but just because we wanted to only get clicks from people who were actually honestly interested in buying a t-shirt, maybe. This is a very different prospect from advertising a free webcomic, just to get people to pop over and have a free bit of entertainment. I think those kinds of clicks are a lot easier to get — but it’s also impossible to measure ROI on them, or, at least, very very difficult to.
Speaking of ROI: there is none yet. We still haven’t made any shirt sales as a direct result of these ads. We’re selling shirts here and there, mind you. But none as a direct result of these ads. Yipes.
