A big round of applause to Rogi , for setting an awesome new run-length record of 70 correct answers in a row! Amazing!

AmK also deserves a round of applause for breaking into the top 5 run-lengths with a cool 45 correct answers in a row!

Amazing job Rogi and AmK!

Happy Deepavali to all of you!

    Heh. Apparently if you order people to download it (“Download now – free”), 3.6% more people actually download it than if you ask junta to “try” it.

    And since you mention a term, I guess you want “call to action”.

    Oh damn, wait. 41 choices. Multivariate optimization. Sorry for triple-answering!

    On a side note, perhaps I could get a special mention for record number of comments on a single post? :P

    Make minor changes in copy, shades, icons and so on and run bucket tests to see if there is change in performance.

    In the Mozilla example above, it is ‘Try’ vs. ‘Download’. Google fiddled around with 41 shades of blue.

    Oh, and it’s called Data-Driven Design

    The statistical/marketing term for this is
    A/B testing ( Split testing), where subtle changes are made to the design [ in this case try firefox / download firefox], and the user response is measured.

    Users are shown webpages in a random fashion out of a pool of design choices.

    This is the infamous thing with google. 41 shades of blue, damn.

    A/B testing.
    Or, more generically… Data driven design.


  8. Multivariate testing?

    Mozilla tired out the two variations of the download button to determine which one is more effective.

    And the guys at google constantly make minor changes to their layout to attain nirvana ;)

    I kind of do this at work, but I don’t know which term you’re referring to, exactly, of the following

    – multivariate testing or a/b testing
    – modular design
    – usability testing
    – discrete choice models
    – (google) website optimizer/optimization

    Dammit I vanish for a couple of days and miss out on two really good ones :(

    Answer to this one: Multivariate testing in landing pages?
