Adwords Affiliate URL's

Can you link straight through?

[dazz]

If I have an advert and have the display URL as mydomain.com but the link through is affiliate.com=mydomain.com?blahblah is this allowed?

If it is allowed do you have to put "aff." on the advert?

Please confirm this for me!

Thanks

You can link through directly as an affiliate. But, you are required to announce yourself as an affiliate by including 'affiliate' or 'aff' in your ads.
