Yes, we’ve added Google ads (o’er on the right side). We generate a decent amount of traffic here, especially off searches relating to trademark law, and especially one very special phrase. Yes, some of the ads are for law firms offering cut-rate trademark registrations (especially on permalink pages about trademark developments, etc.) which I could filter out — Google ads allow you to filter out your competitors. But I don’t offer cut-rate trademark registrations (or anything else), so they aren’t my competitors. So I’m happy to charge them for the privilege of riding on Likelihood of Confusion’s popularity (and search-engine friendliness).
So, yeah, I’m looking forward to cashing in and paying for one day’s electricity… as long as I keep the a/c on low. Just call it the new austerity.
