@Rob I got your point.

But every JV page posted on the "JVNP index wall" claim they have got 4%~6% conversions. So maybe it will boost the conversion more than 1%.

About the traffic, of course we don't need to get it all by ourselves. If I have got high converting salespages, I will test it, prove it. Then I will get more affiliates.

In fact, the first thing come up into my mind that cause me looking for a good copywriter is "I need a good salescopy to attract more JVs."
