How to increase clickbank gravity for a product

This ^^^^ exactly.

It may be that 90% of affiliates are attracted to a high/rising gravity, but those are the 90% of affiliates who, between them, will typically bring in 5% - 10% of the affiliate-referred sales. To the other 10% of affiliates (who can collectively produce 90%/95% of the potential sales) a high gravity figure will be either completely irrelevant or (to some of us) even a slight detractor.

It's one of those issues which has two totally different attitudes and consensuses of opinion about it, depending on whether you ask "ClickBank affiliates" or "affiliates who are making a living by selling ClickBank products" - they're two completely different groups of people.

I could tell you, but then I'd have to kill you.

It's one of those questions one can't answer without potentially offending large numbers of people. But look at it this way: if you speak to almost any high-volume vendor, they'll tell you that 95% of their affiliate-referred sales come from 5% of their affiliates. (A less high-volume vendor will tell you 90% and 10%). They'll be far too polite and tactful to comment on their secret skepchick suspicion that 95% of ClickBank affiliates have very, very little idea of what they're doing at all, and of course I'd never dream of implying any such thing, myself.

Another only slightly different way of looking at it is to hypothesize that 95% of ClickBank affiliates imagine that there's some sort of correlation between gravity and sales volumes, and/or between gravity and conversion-rates, and they'll feel more secure promoting high gravity products because their instincts and assumptions tell them something like "Well, at least we know those products are selling well". This is what I started off believing, myself (together with a lot of other nonsense right out of the Urban Myth School of internet marketing - and that was why I earned almost nothing for my first 3/4 months ). Internet marketing can be very counter-intuitive.
