If you plan to do a lot of email marketing, you’ve got to be good at building landing pages for your campaigns. Landing pages are very simple web pages that are
built for one thing: conversions. Either a conversion to download
something, sign up for something, or best of all, buy something.
Here’s a nice post from the Vertster website with a list of 25 things you can test on your website. It’s written for websites in general, but you can use these tips to test the performance of all your landing pages too (more on landing pages here). If you want a way to track conversions from click-to-buy, try Google Analytics or ConversionRuler.com. And if you really want to get all scientific on your landing pages, bookmark marketingexperiments.com and buy this hideous-but-tremendously-useful book: Call to Action.
