who hire me as a JV broker is how many clicks and sales
can they expect.
They want me to take all of the proposed JV partners'
ADVERTISED list sizes, guess at a click through rate
and tell them how many sales they can expect.
The problem with that is that I'm convinced that 90%
of people LIE about their subscriber numbers AND conversion
rates when you ask for them.
On top of that, some who agree to do dedicated mailing
mail to old rarely-used lists, or just post Tweets, or
other social media posts. I think this happens a LOT with
ad swaps too... the partner does see some traffic and can
track it to their partners, but unless they use something
that also tracks the origin of the click, they don't know
where the traffic is coming from.
On top of that, a list of 1000 can generate more sales
than a list of 50,000 IF the bigger list is tired of being
abused, and the smaller list gets a lot of value out of
the newsletters that they get.
What's my point. While it's good to guess at what response
rate you can expect... it is just a WAG!
And the only real answer comes from testing both the
traffic source and your conversion process.
