Does low traffic affect relevancy of ads?

I'm seeing some weird ads on low-traffic pages.

On pages that get pretty low traffic (in the order of ten unique views per week) I'm seeing totally irrelevant ads when I first view the page.

A refresh of the page seems to cause very relevant ads to appear, but I doubt the visitors are going to refresh pages just to see if the ads change.

Has anyone else seen this on their low-traffic pages?

Google decides which ads to put based on historic values on how much this ad generates on your page.

So if a page is new or has no solid history (low traffic) the Google will most likely keep swapping ads around till the formula factors are determined.

As for relevance, that takes a passenger seat to earnings.

Refreshing does seem to make a difference; I'm not sure why. I have some high traffic pages that when you first come to them from Google, they don't show terribly relevant ads, but as soon as you refresh them, they do. The site is database driven, and I always thought that might have something to do with it.

Nope. My pages are static.

And in terms of irrelevancy, I was seeing ads for cosy rural cottages appearing on a page about a small form factor PC.
