CBEngine.com does a lot of what you are asking about.

Just go to the CB marketplace, click on the Health & Fitness category and then use the filters to sort the products (by gravity, rebill amount, date...etc). Here's the link:

Hi Frank,

You can't get this information for the simple explanation that sales figures are not disclosed by ClickBank. Not to you, not to me, not to affiliates, and not to the owners of sites like "CB Engine" either.

There are some strange websites which try to "estimate" what's selling well according to their own so-called "secret proprietary algorithms" ( ) but the reality is that they have no information at all to which you and I don't also have access, through ClickBank's Marketplace statistics.

What they commonly do have is a deeply misguided and erroneous assumption that high gravity products are necessarily selling well. That's nonsense, of course, because contrary to what some people assume, there's actually no correlation between gravity figures and numbers of sales.

No, this information is also not available. An affiliate buying one copy of a product through his own hoplink (as many do) and an affiliate selling 5,000 copies of the product through his hoplink both add exactly the same 1.0 points to the product's gravity figure.

That's one of the reasons why there are so many products with single-figure gravities steadily outselling products with three-figure gravities. "Popularity" is all that gives any indication of sales numbers, but the precise inputs to its algorithm are undisclosed, and so (of course) are their relative weightings: that one really is a secret formula".

You cam sort by gravity which is derived from the number of unique affiliates who made recent sales, and by commission amounts, but there is no way to compare vendor's total sales, or their conversion rates.

The default ranking of "Popularity" is showing you who is making the most sales. Per ClickBank... "Popularity is determined by a publisher’s net sales over a recent time frame and also rewards vendors who have many affiliates promoting them."

So although there is some weight given in the Popularity equation that's factoring in affiliates also, you can get a very clear idea what products are selling the most. For example the products in the top 3 positions are doing better than people ranking well below them.
