An email showed up in my inbox a week or two ago, saying that Google would give me a $100 AdWords credit for spending $25. Since that’s basically a free $75, I could hardly say no.
It’s been interesting watching traffic stats and ad campaign stats—they drove a good bit of traffic here, but didn’t really yield anybody engaged. (A bounce rate of almost 100% is no good.) I probably could correct that with better ads and better landing pages, but I’m not going to put the effort in just yet. When I release my first ebook later this year, I’ll set up an ad campaign for it specifically, and use up some of the rest of my free ad money.
