The Power of Our Reviews

We’ve been doing our Website Reviews for quite some time now, and recently we’ve also added the Conversion Review to that list. There are some of you, the very loyal ones, who we’ve had the pleasure of helping in both these areas. Today I’m highlighting one of our very loyal customers (he has far more…

Our themes don’t have sliders… Because sliders suck.

Last Tuesday we released our first three themes, and this will be the first post in a series that will explain what themes should and should not have. These posts will also explain why we made certain choices regarding our themes. With the release came a storm of reactions, some downright negative, but most of…

Perfecting your goals in Google Analytics

There are quite a few tracking features in Google Analytics for which you have to do a bit more than just implement the UA-code on your pages. One of those features is the ‘goal’. The goal is a feature in which you can track one of the following things: how many people reach a designated…

Conversion Review Giveaway: The Outcome

Two weeks ago, we did a Facebook free giveaway for a Conversion Review. The lucky winner was the webshop Indigobox Jewels. In this post, I’ll highlight a few of the most important things we’ve come across during the review. I’ll first go through the website as if I were a visitor who wants to buy something.…

Shopping Cart Abandonment

Ever since we’ve optimized our checkout page, we’ve been keeping track of our shopping cart abandonment.

And during this digging, I came across a few…

We’ve come to the conclusion we needed to offer these Conversion Reviews as a result of my own activities within Yoast, as well as our experience with the Website…

Demystifying Viewing Patterns

Lately I’ve been intrigued by something called the ‘viewing pattern’ of people. This is a pattern in which people view, in this case, websites. There are really a lot of ideas about this out there. Now I’m wondering: is there one right pattern? In other words: is there one pattern we should follow when designing our product…

How we built a Checkout Page we’re proud of

Our checkout page caught our attention, because it simply looked shit. There was no clarity, no images, not anything to make it look anything close to appealing. It was basically just a bunch of text. So that’s the first thing we wanted to change. We wanted to make it actually look like a cart and…

Why your tests aren’t scientific

I read a lot of articles about A/B tests and I keep being surprised by the differences in testing that I see. I think it’s safe to say: most conversion rate optimization testing is not scientific. It will simply take up too much space to explain what I mean exactly by being scientific, but I’ll publish…

Planning and checking your Conversion Rate Optimization

During my attempts to optimize the conversion rates here on yoast.com, I’ve met with quite some hurdles and roadblocks. That’s why I thought it would be a good idea to write a post; so you won’t have to invent the wheel twice. Define your Intensive Care Pages Although it’s very tempting to start off your…
