Adsense CTR on a site I'd forgotten about

[pdrs]

Hey Warriors,

I've got an old blogger blog that I had totally forgotten about that has some adsense on it.

I don't use adsense at all but I just looked through and I see that this site has made 30 or 40 dollars over the past year and has a CTR of almost 5%.

The clicks aren't worth much 10 - 15 cents per click.

Just wondering if this is something that would be worth investing a little more time into or if a 4-5% CTR is pretty common?

Any of my other adsense stuff is down in the 0.5% CTR so this looks like it may have some potential?

Thanks,

Rob
