On one of my sites I’ve installed ClickHeat, an open source javascript-based click heatmap script, and appears to work simply and objectively. I noticed this morning that an area that has a giant Large Rectangle block in AdSense has received 50+ clicks this morning (0 of them being from me ). My AWStats records around 1 million pageviews/month and this is a popular section, so that doesn’t seem too unreasonable. AdSense has recorded 0 click for this ad, however, and will probably show no more than 2 for the day as things have been going.
I’ve double-checked the code is right. Numbers haven’t really changed since before I installed ClickHeat (so I wouldn’t say there’s a conflict). Curious if anyone else has seen anything like this? I’ve read that AdSense often “defaults” on an ad if it doesn’t feel like it’s a good impression, but this is all good traffic from real humans so far as I can see (about half is direct from Google, actually), so it’s starting to seem a bit ridiculous.
