What does cf mean in 7 search?

[POLLITO122]

I have noticed that there are many big keywords that begin with cf and they do not have any bid, what does it mean?

cf means "click free". Basically its an expired domain redirect and worthless..... do not bid on them as its trash traffic!

Hope this helps....

People are RARELY successful using cf keywords. I suggest you stay away from them.

Yeah I would stay away if you are targeting stuff! You can get lots of cheap traffic from them but its pretty worthless!

I agree wholly, don't bother wasting your time on click free keywords, they are virtually useless and very unlikely to convert
