We rebuild your highest leverage product or landing page and run it as a live split test against the page you have now. Revenue per visitor is the scoreboard.
We rebuild the page where the money is decided, usually the product page, and run it against your current one on your own traffic.
Your visitors are split between the new page and the existing control, with up to five iterations until the result is clear either way.
Two or three tests a month after the first win, so changes keep compounding instead of resetting with every redesign.
A redesign is not a test: without a control you cannot tell a good page from a good month.
