Cross-promotions

An ideal scenario

Meet Joe and Kate. They run similar newsletters and have a similar number of subscribers, so they decide to work together. Joe promotes Kate in his newsletter, Kate promotes Joe in hers, and some of their subscribers decide that they like both. Joe and Kate gain new readers from each other, and those readers find a new newsletter to enjoy.

Number crunching

Mathematical reality

But what if Kate has a lot more subscribers to begin with? Then she'll be sending more readers to Joe than Joe can send back to her. This is a fundamental obstacle to cross-promotion: newsletters of different sizes are effectively blocked from working together, no matter how much their readers might like them to. Because of this, there are far more newsletters you can't cross-promote with than newsletters you can.

Pooled efforts

Our solution

CrossPromo Club's automated cross-promotions are designed to fix that. Instead of only promoting one other newsletter, each creator can use a single link to promote a list of several, all at once. This enables them to pool their cross-promotion efforts, and we make sure they all get rewarded with new readers.

Mathematics

Making it all work out

Suppose Andrew includes his automated cross-promotion link in one of his newsletter's issues. Every time one of his subscribers clicks it, we'll generate a list of appropriate cross-promotion partners. We do this by combining two factors:

  1. How similar partners are to Andrew's newsletter.
  2. How many of their subscribers they've previously sent to others.

Kate's newsletter is pretty similar to Andrew's, and she sent lots of new readers to others the last time she used her automated cross-promotion link. Because of that she shows up in Andrew's list very frequently and receives the most new readers from him.

We'll remember how many readers Andrew sends to others, and we'll make sure he shows up in their lists often enough to receive the same number back.

What about click-fraud?

We smash bots and fraudsters

Bots exist! So do people who think they can click their own links to inflate their totals. Neither are tolerated at CrossPromo club.
