A large national non-profit association evidently linked to one of my blogs at some point yesterday. I checked AdSense a little while ago for the first time today and almost fell out of my chair. So far today, I've made from AdSense what I usually make in a week! Happy, happy, happy!
@RMC -- No kidding. I'm hoping this sticks and isn't just a flash in the pan. Although two years ago, one of the other sites that linked to the same blog gave it a really nice boost, and that's stayed pretty stable. So fingers crossed! Gosh, I might have to actually start updating this blog!
What's really surprising to me is that it's only a PR4, the page that links to me is deep in the site and a PR0 (not the home page, obviously), and yet they're sending me tons of traffic that converts nicely. I may look at PR4 sites in a new light after this!
