I'm giving Adsense's "matched content" a fair trial near the bottom of my pages. These are my results after a few days.

- My server logs indicate 15% of visitors are clicking through, roughly the same as with other similar links I've used
- My pageviews, as reported by adsense, are nearly 40% higher but my server logs say it's less than half that
- My CTR, as reported by adsense, has fallen by nearly 40%, but again my server logs say it's less than half that
- Overall I am serving more pages for slightly less in total earnings

More importantly:
Am I making my visitors happier with this? That depends, are they finding what they want on the page matched content is sending them to?

Am I making search engines happier with this? That depends, are visitors finding what they want on the page matched content is sending them to?

I am watching which pages are being considered "matched" closely and so far it's OK. I plan on using this as a tool too to find candidate pages to merge and consolidate if they aren't significantly different enough for my liking and/or continually take a visitor off my best page onto a lesser page with a more tempting title.
