How Split Testing our Banners Increased our Profits 138.46%

A recent study by Hubspot demonstrated the evolution of digital advertising in recent times and how display advertising has had a rough time as of late trying to compete with newer forms of advertising such as native ads and mobile.

However, it proved you can still achieve huge results with display advertising even in 2016.

If you’re not aware of what display advertising is, in the simplest of forms it’s the means of advertising something on a website via a banner ad, video ad, or something visual. The most common of which is the banner ad, a banner or image served as a medium between the site you’re advertising on and the site you’re looking to advertise.

Banner ads come in all shapes, sizes and formats, but the most common ones you see on websites are these:


Obviously revenue and conversions are what’s most important when it comes to serving banners, but often these go hand in hand with the better clickthrough rate. Clickthrough means someone actually clicking your banner and going through to your site.

In this post, I will show you how we utilise banner ads on our platforms to full effect and how we were able to double our monthly revenue from a few simple split tests on one specific banner placement.

First let me start with a fact:

“The average clickthrough rate of display ads across all formats and placements is 0.06%”.

That means that for every person that visits your website, only 0.06% is going to actually take notice and click your banner (on average). This is obviously quite a low percentage; however, if you get enough traffic, it’s still very possible to make some great profits off of even as low a CTR (click through rate) as 0.06%.

Whether you’re doing direct media buys, running banners as an affiliate, or fulfilling your own inventory on your own web properties like we do, there are some easy ways you can get more from your banners.

We like to run our own banner campaigns on our forums from time to time, purely because we can often make MORE money running internal offers than we can selling the banners. Even though we can charge a premium, we see fantastic results painting the spots ourselves.

Recently, we started promoting the amazing new affiliate intelligence tool AdsXposed, which if you’re a mobile affiliate reading this, you need to check out my review here.

We started off by getting some very simple banners made in order to get some results and then putting them up on one of the leaderboard spots on The initial results were very good, but I knew we could get more out of the placement and overall improve our CTR on the banners.

I looked for a suitable tool to split test some new banner concepts and stumbled across the fantastic

For those of you who are unaware of, it basically lets you split test different banners against each other by providing you with a banner and link rotator and all the stats you’d need to calculate results.

Below you will see how we then managed to improve our CTR by over 100%.

Banner Split Tests

Week One

We started out by serving up the following banner:


It was simple but effective and initially yielded some good results, bringing in some good early clicks and revenue in week one with no split tests at all.

Best Banner CTR: 0.25%

Week Two

In week two, we introduced some completely new banner designs. We wanted to make sure no two banners looked alike as we were first testing designs, and then we would split test colours, etc.:


By introducing some more banners, the clicks per banner obviously decreased as they were spread out, but we managed to outperform our original banner by 0.13%.

Best Banner CTR: 0.37%

Week Three

In week three, we removed the two worst performing banners and replaced them with some different colour concepts of the best performing banners:


It was interesting to see that we’d now more than doubled our original banner CTR with one simple test. The numbers and conversions had also doubled on the back end so it was well worth the test.

Best Banner CTR: 0.60%

Week Four

In week four, we again removed the worst performing banner and introduced a few new colours to see if it would have any effect on the CTR:


The main takeaway here was that – no matter which colour combination we tried – we had found a clear winner with an average CTR of over 0.60%, which if you go back to my first statement about the global average being 0.06%, we’re pretty happy with.

Best Banner CTR: 0.61%

Now to put this into perspective, if we had run with banner number one and not split tested, we would have received over 100% LESS clicks and subsequently 100% less revenue. As you can see from this brief snapshot below, the revenue generated over the course of the month compared to the previous month was substantially better:


Now, there are lots more things we’re going to start split testing when it comes to our banners, so this is by no means the end. Here are a few things you may want to try:

  • Colours
  • Copy
  • Call to Action text
  • Headlines
  • Fonts
  • Images
  • Animated Vs Static

and more….

These are just some things we’ve noticed when it comes to improving our banners CTR so far:

  • Green works best
  • Use bold fonts
  • Keep it simple, stupid
  • Less animation is more
  • Small animation over Static
  • Big call to actions
  • Rotating banners work

The last point is one most people actually forget about. When it comes to banner ads, visitors can often experience banner blindness if they’re seeing the same banner over and over. We actually saw better results from constantly rotating several banners at once, as opposed to one banner.

Here’s how you can start split testing your banners and improving your CTR today.

Sign Up For

The best thing about is that they offer a 30-day free trial, so you can even split test your banners for 30 days for free and see if it’s worth your money upgrading to an annual account, as I have just done.

Once you’ve signed up, log in and navigate to Banners in the side menu and click “Add Tracker”.

Next, from the options select: “I want to track views of banners”


On the next step, fill out the following:

  • Tracker Name: The name of the placement of your banner
  • Banner URL: Your first banner image URL
  • Link URL: The link that your banner will click through to

Then, click the option to “Add Another Banner” to add your split test banners in.


Once done, click “Next Step”.

On the next window, you’ll be presented with your:

  • Banner URL: the image link
  • Site URL: the site link

Embed these within platform or using HTML in your site:

“<a href=”Site URL”><img src=”Banner URL”></a> “

Then, you simply need to give it some time and log back in to check your results.

We’ll be split testing other elements of our banners over the coming months and will follow up with this post soon.

I hope it helps!
