Color Coding for Clicks / Impressions (CTR)

I'm trying to figure out the three different color codes for the Clicks  / Impressions (CTR) in our Analytics. 

I see Green, Red and Black

Can someone please explain what the difference is with the three colors?

Thanks

I'm sure you'll get an official answer but I *think* it's just green for links that have been clicked and red for links that have not.

The only black I have are the dates in the Created column. Do you have more black?

That is correct, Christene.

Green = has received clicks

Black = has received few clicks (approx. < 2% CTR)

Red = has not received clicks

Always for the specified time frame (90/60/7 days).

If a module is consistently red it may be time to experiment with a different position, or try other products.

If red has received no clicks, then why am I seeing numbers for Clicks / Impressions?

It looks like they might be changing over time?

It could be that the CTR is very low. We'll have to ask Hans/Simon for the exact limits, but I'm thinking it's probably under 1%.

In any case, the color on your stats is just for your own personal use, to quickly enable you to see what works well and what might need improvements. It has no effect on anything else.
