SarahG has been incorporating link units into her site and has had some awesome results:

In the past week our AdSense has increased by around 50%. The link unit now accounts for almost 33% of the total income for that site for the month so far.

That was SarahG’s initial results. A week later she writes in Our first $10+ AdSense Day

The link unit I added contributed to almost $4 of this. I can’t believe we’ve been missing on this extra revenue from a link unit all this time!!

Congrats SarahG, I love hearing good news from my blogging peers.

Adsense is a bumpy roller coaster ride but I find keeping multiple link units keeps my average up a bit as apposed to not having them.
