Hello you all,

I asking you guy a short explanation.
I'm planning going in the business too, and I'm actually reading and getting infos a lot.

But, I'm not a native English speaker.
Altough I can usually catch what anything means, I fail to firmly grasp the concept of "conversion".

Could someone explain me exactly what it is ?

My guess would be a valid unique visitor sent to a referral site, who have buyed something, but I'm not completly certain about that.

Thanks for the explainations.
Tripy.
