Whilst this is not something that will interest most people, I have started noticing that Google is currently testing the colour of the sponsored links sections.
Update: Google have now confirmed this is not a test and is rolling out to everyone http://atelier-seo.com/2010/07/confirmed-google-changing-sponsored-links-colour/
Over the last couple of days, I have noticed the colours changing from the usual yellow colour to a rather pale purple (pink in my eyes) that you can see below.
Obviously we know that Google is always testing its SERPS and this is not even the first time that the colour has changed, anyone remember the old blue one?
Anyway, who knows if it is going to stay, but what do you think; Pink or Yellow?
Noticed that myself the other day. But then i guess that is the point. Perhaps people got so used to the yellow bar at the top of any given search that they started to automatically skip past it. Changing the colour has certainly made me aware of it anyway.
