Hi
The ads that are showing on my pages are perfectly targeted to the content - but I seem to be getting a high number of UK sites in the results.

I don't have any UK references on the page - like most sites I gear things on the assumption that 80% of my visitors are from the USA.

In my Adsense sign up, my address is given as from the UK - are they using this information to assume that just because I live in the Uk, my website is probably targeted at UK visitors?

This is going to ruin my CTR - most of these UK sites are not going to interest 80% of users.
