So, now that the Rat is starting to ramp up this blogging thing, it seemed like a good time to try to monetize the thing. So he signed up for a Google AdSense account, and went through the rigamarole of setting up ad boxes.
Imagine his horror when the first advertisement to show on his blog was for “Rat Breeding Services.”
“I am NOT running a prostitution site,” he said, banging his head.
He tweaked his metadata, and futzed with the AdSense configuration a little, and gave it another go.
First ad: “Rat Cages & Housing, Large stock of Rat Supplies. Cages, food, treats, and more.”
Clearly, this was not going as planned.

Heh.
I’ve experienced worse. You have to lock down your AdSense channels fairly tight or you’ll be surprised what shows up. It’s all based on content in and of your pages. If you call someone an expletive or use a perjorative term, you can expect AdSense will cater to that as well (ugh). It pays to be Ad-Aware when writing.
Something to think about.It would be nice if you could target the content better, but it is driven off of the site crawler indexing your content.
