idea which change affected the conversion rate. Let's suppose you're testing a
pre-sell pitch. If you change the headline AND the P.S. on your pitch and
then experience a significant boost in your conversion rate, you won't know if
it was the headline or the P.S. that caused the change. That's why you need to
test just one element at a time while holding all other variables (including
traffic sources) constant.
Use tools. Fortunately, you don't have to track and test your campaigns
manually or crunch the numbers with your abacus. Instead, you can use tools
like Google Website Optimizer, split-testing scripts, and multivariate testing
software. All you have to do is make the changes and let the tools do all the
work.
Bonus Tip: If Google Website Optimizer isn't the tool for you, then run a
search in Google for "split testing script" or similar to uncover plenty of
solutions, both free and paid.
Don't judge too soon. You send one hundred visitors to an offer and make
two sales. Does that mean you have a 2% conversion rate? Maybe. But it's
too early to say for sure. And that's because you generally need anywhere
from 30 to 50 "actions" (in this case, purchases) to generate significant
results. Point is, be patient. Plenty of affiliate marketers just skip the whole
testing and tracking thing. But those who do are leaving money on the table.
That's why I strongly recommend you start tracking and testing if you're not
already doing so.
