[Innovation] Bye Bye Flicker effect
Yes, you read well. No more Flicker effect.
A/B testing and personalization are powerful marketing tools. They help you understand the user journey, your visitors’ needs and create tailored experiences for them. They let you take decisions based on reliable data and implement an optimization strategy with great ROI. Amazing. But these advantages can be reduced to nothing in the blink of an eye.
How: the Flicker effect
Our R&D team has once more outdone itself and has come up with the first Flicker-free technology ever. Don’t go looking elsewhere, there’s just nothing like it!
What exactly is the Flicker effect?
The Flicker effect is like a butterfly effect, a little flash on one of your web pages, but with big consequences for your business. Visitors sometimes see it on A/B tested pages. The reference version appears for a very short time before the variation builds up.
The consequences are clear: The user experience is largely deteriorated. Visitors will ask themselves why elements are changing, they will realize that they are being A/B tested, or worse yet, will see a special discount that is not for them. Evidently that can make them lose trust in your brand and leave your site. In any case, the results of your A/B test will be biased because the users will change their behavior.
You have certainly already been exposed to the Flicker effect while surfing on the Internet. Isn’t it strange that many websites continue not to address this important issue?
Kameleoon has always been a pioneer in this field and has taken its efforts yet a step further to definitively do away with this major problem.
How does that work technically?
Spoiler alert: geeks only 🤓
And that’s how the Flicker effect can appear. While your page is loading, the browser refreshes the display regularly and automatically. It’s not impossible that an element supposed to be changed is identified in between 2 updates. In that case, the reference version will appear during that interval. Knowing that there is no fixed interval between browser updates (there can be 5 within 100 ms, then none for 3 seconds), one can easily understand the negative impact of a Flicker effect lasting several seconds.
Kameleoon’s promise? Make marketing teams’ work ever easier and help them create tailored experiences for their visitors. The Flicker effect has always been known as a potential risk for A/B tested websites. So we gave our very best to solve the problem and find a reliable solution. As of today, we are the first and only A/B testing and personalization platform to guarantee a Flicker-free technology, and we are very proud of this!

A team of overachievers
These optimizations had already significantly reduced the risk of a Flicker effect, but it was still out there… so we continued thinking.
Our new anti-Flicker technology builds upon the latest browsers updates. It is the result of months and months of research, hard work and multiple optimizations. The result is the complete disappearance of the Flicker effect.
So what changed?
The old script asked the browser every 100 ms if there was a new element to be edited on the page. If that was the case, Kameleoon went on editing. If the browser was refreshing the page during this 100 ms interval, Kameleoon was not able to change the element, and the risk of a Flicker effect was there.
The new Flicker-free technology doesn’t work like that. Kameleoon no longer asks the browser, it’s the browser that informs Kameleoon in real-time. Kameleoon’s algorithms are now able to change elements that appear in the HTML code immediately, which means that we can guarantee a Flicker-free display of your A/B tests and personalizations.

And there is more good news: no additional installation is needed if you are already using Kameleoon. For those who don’t, why not ask for a free demo to see how it works?
