I will be implementing Google AdSense very soon as a way to pay the costs for this blog. It's been ad free for over 8 years, but now I'd like to recover some (likely a tiny fraction) of the costs.
A massive percentage of the traffic to my site is coming from search engines and most of that traffic goes to only a few pages. I'm considering only placing AdSense on individual archive pages and not on the home page (and probably not in my RSS feed either). This would effectively only target those random people who arrived here via search and not those who regularly read the site.
