Google Adsense Now Shows Earnings in Pounds
For all the British Adsense clients out there, there is some good news. You can now switch your reporting from USD to GBP. Finally daily revenue can be seen immediately, without having to look up the current FX rate and grabbing the calculator. I am not sure at the moment if the GBP figure is just a guideline and then adjusted daily / monthly, or if Google is using daily spot FX rates. Hopefully the latter, that we know for sure how much money we are making in the month.
To update your account from dollars into pounds just look out for the prompt when you next sign in to your Google Adsense account, or click on your account and change preferences.

I also noticed this – well google has a big market share in the uk
It’s optional, shall I update to pounds? Is there any defects, such as VAT?
If you are a UK business, then sensible to convert to pounds, if only to make tracking revenue easier. Not sure about VAT, but the UK tax system works differently to the US, so they probably will not / cannot deduct tax at source as most people will have accountants to sort the tax out for them.
