A very common scenario: A business runs tens and tens of A/B tests over the course of a year, and many of them “win.” Some tests get you 25% uplift in revenue, or even higher.
Yet when you roll out the change, the revenue doesn’t increase 25%. And 12 months after running all those tests, the conversion rate is still pretty much the same. How come?
Even if your A/B tests are well planned and strategized, when run, they can often lead to non-significant results and erroneous interpretations.
You’re especially prone to errors if incorrect statistical approaches are used.
In this post we’ll illustrate the 10 most important statistical traps to be aware of, and more importantly, how to avoid them.
As a business, your email list is one of the most valuable assets you have. The bigger your list and more engaged your subscribers, the more money you can make.
Having a well-thought-out plan for A/B testing Facebook ad campaigns is essential if you want to improve your performance reliably and consistently.
And the more you test, the better. A study of 37,259 Facebook ads found that “most companies only have one ad, but the best had hundreds.”

When should you use multivariate testing, and when is A/B/n testing best?
The answer is both simple and complex.
Lots of entrepreneurs struggle with pricing. How much to charge? It’s clear that the right price can make all the difference—too low and you miss out on profit; too high and you miss out on sales.

On one hand, having a phone number can increase the trustworthiness of your website, help sell potential customers who aren’t comfortable buying online, and allow customers to contact support easily.
The flip side? Phone support costs money.
Many anecdotes support both strategies, but we should be asking, “Where’s the data?”
Marketers of all stripes are obsessed with tools.
This obsession has bred comprehensive lists of growth tools, SEO tools, and general online marketing tools. It is no different with us in conversion optimization. We nerd out on testing tools.
Though no optimization program has ever hinged on which tool you used, there are important distinctions between A/B testing tools—from the statistics they use, their price, and more.
One thing that is often either overlooked or misunderstood is the difference between client-side and server-side testing tools.
If you run an ecommerce shop, you’re always trying to boost your sales. Here’s how to increase the conversion rate of your ecommerce site.
Read any copywriting manual or article, and it’ll tell you that the headline is the most important part of your sales copy. That’s true.
Unfortunately, the advice that follows is often originates from snail-mail sales letters from the 1950s. I researched 500 headlines of successful online businesses and figured out which formulas work today.
