Imagine, you’re selling your eBook or downloadable product using ClickBank. You think you can improve your sales letter (and thus convert more of your visitors into customers), but you’re not really sure whether your changes will be improvements or not. So you need to test. Now you can find all sorts of complicated software for split testing, but if your web host supports PHP, I can show you a dead easy way to do it, that doesn’t cost a penny.
- Imagine your existing sales letter is called index.html, first rename it to index1.html
- Next make the variants of your sales letter. called index2.html, index3.html, etc. (at least one, but as many as you want)
- In each of these variants, include a sales link to sell a different ClickBank product. For example, index1.html sells ClickBank product 1, index2.html sells ClickBank product 2, etc.
- In your account, you can set the thankyou pages for each of your ClickBank products to the exact same URL (after all the customer will get the same product regardless of which particular sales letter they see). You can set the price of the products to all be the same, or if you’re split testing different prices, vary the prices between the products.
- And now the clever bit…. you create a PHP script that displays each of the different sales pages at random.
Start Notepad, and enter the following:
<?php
$npages = 2 ; // change 2 to the number of sales pages you have
$n = ( time() % $npages ) ;
include ( ‘index’ . ($n+1) . ‘.html’ ) ;
?>
Now save the file as index.php (if you are using a version of Windows prior to Windows XP, you will need to type the name in the Save As dialog as “index.php” including the quotes, or else your file will be named index.php.txt).
Now upload your index.php to your site.
If you visit your site’s main URL, you should now see one of your sales pages loaded at random. If you click Refresh in your browser, different pages, should randomly rotate in (sometimes you’ll get the same page, sometimes you’ll get a different page). But the chance of any of the page being loaded is the equal.
And the result? As you run it, you’ll be able to see which version of the sales letter performs better, because its corresponding product number will occur more often in your ClickBank stats.
What should/could you test?
- Different headlines
- Different colors
- Different sales letters
- Different prices
- Different guarantees
Vary one thing at a time, and eventually you’ll find the sales letter which converts best, and therefore makes the most money for you.
