Principle of commitment & consistency -- When people commit to something, they're far more likely to purchase from you. That's why getting them to agree to something like a free + shipping offer or by agreeing with something you've said in some way. This is a powerful principle in sales and if you pay attention to some of the best marketers in the world, you'll notice that they work fervently to get your commitment to something, even if it's very small in the beginning. 
A/B testing, or A/B split testing, is a method for testing two versions of a webpage: version "A" and version "B". The goal is to test multiple versions of webpages (e.g., home page vs. product page) or one specific element that changes between variation A and variation B (such as having a lead form on the left hand side or having it placed on the right hand side), FAQ to determine which version is most appealing/effective. This testing method may also be known as A/B/n split testing; the n denoting more than 2 tests being measured and compared. The data for A/B testing is usually measured via click-through rate or an alternative conversion tracking method.[11]

Watch Hubspot’s tutorial to create a thank you page that nurtures leads.

If you want a basic site, you could upload a theme, or use your hosting company’s theme builder and get online but that doesn’t mean you’ll get what you want necessarily. WordPress itself is a basic, open-sourced software tool that really does nothing. It will take a bit of know-how and expertise to learn how to use, but if you are above-average tech savvy (or learn things quickly), you can figure out how to get online.

When I first wrote this article in 2011, I mentioned how the marketing copy for Crazy Egg’s heat-mapping feature could have been stronger by better explaining how the tool helps customers to increase conversions. While this information is clearer now thanks to the detailed visuals and simple copy layout that allows the reader to skim and scan — it could be better by explaining a bit more.
