Can anyone tell me if there is a way that I can filter Adsense to only show ads from the UK on my site as the majority of ads that my site shows are for American ads. As they seem to be for small US companies, they prob wouldn't even ship to the UK I would be really grateful for any help
I would think that would be a natural consequence of your ip, content and URL. Have you tried Google Webmaster Tools? You can set a Geographic Target in 'Settings'... perhaps that will assist.
Yes, use google webmaster tools and try to display your site in UK region only, then i suppose you will get the ads from uk , try it.
You can test your Ads for different regions using the 'Google Ad Preview' tool. Just select the region from the dropDown and it will show you the relevant Ads that will be displayed on your site when a user from that particular country will visit your site. You can also test the ADs by clicking on them while in Google Ad Preview tool so that you can filter out MFA sites or sites that think won't interest your visitors etc.
I think you'd perform better if you let Adsense decide which ads to be shown on your website. After all, the more money you make, the more money they make! Just block out the MFA sites in your Filter feature.
