    How to do efficient optimization

    Wednesday, July 2nd, 2008

    A beginner’s mistake is to test every idea with every test. This is the most obvious way of being efficient. If I can test 50 things in a week, why not?
    In my experience, efficiency has more to do with careful test design and doing things right the first time, than trying to test [...]

    Monday, March 17th, 2008

     

    Every test teaches something. Almost every campaign test has the goal of raising conversion rates, but really the power of testing is in answering questions. It is just a happy coincidence that it raises your conversions at the same time.
    Here are a few of the questions that can be answered with testing:

    3 ways to maximize PPC and Landing Page Optimization

    Thursday, February 7th, 2008

    Quality PPC and LPO campaigns are key to great conversion rates. If either of them are optimized, you might get good results, but with both of them optimized, your gains are exponential. There are a few pitfalls in optimizing them both though, even with good intentions you may end up confusing your results [...]

    Test nothing and get results

    Friday, January 18th, 2008

    Now this is a blog about testing right? So why test nothing? Because nothing is powerful.
    I don’t mean don’t test at all, I mean test having less on your page. Those awesome sub headlines your copywriter created? Or those testimonials? Your audience might not care or even look at them.
