I made the decision a couple of days ago to remove weight loss (and a bunch of other low quality) ads from my site having been told by a friend that google gives that option.
As you can see from the below image that should have cost me 20% of my revenue (stretching to around 25-30% with everything else I blocked) and with even backfill (as another friend pointed out on my Facebook note) I should really have only lost 10-15% of my revenue. No biggy and a warm feeling at that.
It turns out that isn’t what happened.
So I essentially halved my cocktailmaking.co.uk revenue which definitely cost me $1000s (I am hoping for a rebound in revenue next year as adsense retrains to the new ad selection otherwise this will have cost me more than $1000s :( ).
I still feel good about the decision though. When I was describing the change to my mum she told me about clicking on one of the ads on my site herself and she was smart enough to see it as a scam and pull out.
There is a lot more to be said on this subject. The most important point is that it’s hard for small publishers like me to keep on top of stuff like this but the remnant inventory ad networks can only make decent money by running these scam ads. This creates a very difficult situation.
We really need the brand building $$$ to start flowing online. I have an audience of 400k people this month with the vast majority in the US and UK. A magazine or newspaper with that circulation can command far higher revenue for that. Some day I hope the web will be able to do so as well.
