Most of the scammed use some of these traffic exchanges and it could possibly ruin you credibility with trying to promote honesty. I 2 as once a member of Plug in profit site and they used this method in the training and I encountered many many scams on the traffic exchanges

I never heard of them.

Never heard of it.

No I have not tried that one

Just my opinion, but I'd be leary of such exchange. I just think it could get complicated and make a mess of my FB page. That's just me though.

I haven't done that. Are you thinking of it?

hmmm, Link exchanges are just that- and if they are not natural I would avoid them.
Facebook Fan Page for classic cars likes ballet school Fan Page, which likes them back- how does that sit?
A like is a like, but if this is done on a large scale it will be one of those things that is penalized in due course by a review...etc.
Better to put efforts into generating content that sings and that gets organic shares and likes in my opinion.
Then there is the matter of time spent-
If you are having to put time aside to do this it will cost- and you will end up with a FB account that looks a right mess.
Just my thoughts, Andy

I have never heard of them but would be interested to see what answers you get

I never heard about it. Sounds interesting. Tell me more!
