People in this forums said: Blend Use blue (same as default link color) Use red (hot?) So which one is the best, say for serious sites.. (BTW I appreciate getting my green rating back, I didn't say an unethical thing).
I try not to rock the boat and stay with blue for all my links, whether they be AdSense links or site links.
I chnage it up quite a bit for my sites -- just whatever looks good. But I will normally leave them underlined so people know they are links.
I would go along with blend. You don't want adverts to stick out. You want them to blend in with the site and not scare people off.
it all depends on your target audience, and what your site is about. different colours will appeal to different people.
