How To Improve CTR Instantly By Tweaking This Colour

If you’re a full time SEO then it is likely you track a huge range of metrics on your site and you are not so bothered about how to improve CTR.

Most people tend to focus on:

  • Where they rank
  • The amount of traffic they are getting
  • How much money they are making

SEO’s are usually very busy people managing lots of sites so it’s logical to focus on the core metrics.

But there is another much more important metric you need to focus on which could be costing hundreds/thousands in commissions every day.

Conversion Rate Explained

The conversion rate is the percentage of people that visit your site compared the amount of people that complete a specific goal which you can track with Google Analytics event tracking for example.

A Goal can be anything from a newsletter signup to clicking your affiliate link.

How To Improve CTR

For example if 100 people a day visit your page and only 1 of them finds and clicks your affiliate link you have a 1% click through conversion rate.

There is a case study at the end of this article that shows you how to improve CTR & how I increased revenue of a site by 20% just by changing the colour of a button.

Why Is This Important?

Well let’s assume you have a 1% click through conversion rate which earns £10 per day. 99% of the traffic goes to waste which leaves an awful lot of money on the table.

If you increase it to just 2% you could double the amount of money you earn…

 With the same amount of traffic.
Let’s face it, getting a website ranked in Google is hard work so once you have a steady flow of traffic you need to maximize the earnings per visitor as much as possible.

And the best way to do that is to learn how to improve CTR on your site.

Conversion Rate Optimisation (CRO)

This will vary depending how you push people through your affiliate link. Some people just use straight text links while others will use price comparison tables, buttons or banner advertising.

We can setup tests to measure how effective your affiliate link placement is and then test it against other variations to see which gets the better response from your traffic.

It sounds complicated but here is how it works, let’s assume you have a blue buy now button-

  1. Create a red version of the button
  2. Show half of your traffic the red button and the other half the blue button
  3. Measure which one gets the highest click through rate
  4. Take the winning button and setup another test to improve conversion further

You can literally test anything from link placement to the link text color. Even testing the headline of the page can reduce bounce rate and improve click-through rate.

So now you know how to improve CTR – make sure you test everything!

I would recommend you start by optimising your affiliate links though.

How To Improve CTR Case Study

The best way for me to illustrate this is with one of my own conversion rate optimisation tests.

I have a website and the sole purpose is to get the user to click on a banner with my affiliate link.

The original banner had a 41.5% click-through rate and looked like this (I removed the text)-

Original Banner

I then create 4 variations of the banner which looked like this-

blue banner version

Combination 1 - Blue

red banner version

Combination 2 - Red

purple banner version

Combination 3 - Purple

orange banner version

Combination 4 - Orange

I setup a split test for all of the banners which would rotate them evenly to my visitors. With 5 banners in the test they were each shown 20% of the time.

I use Google Website Optimizer for most of my conversion rate experiments which is free and easy to use.

I let the test run for a week to collect enough data to make a decision on. You might need to run your own tests for longer depending on traffic volume.

The Results

The results are actually quite interesting-

banner colour split test results

As you can see the original banner had a 41.46% click-through rate and was actually the worst performing banner out of all of them.

 The best performing banner was the Combination 2 which had a massive 52.25% click-through rate. That is a massive improvement to the overall click through rate of the page.

In total I ran 7880 visitors through this test, if they were all shown the original banner I would have gotten 3,267 clicks to my affiliate link.

If I had shown them all Combination 2 then I would have gotten 4,117 clicks to my affiliate link.

That’s an extra 850 clicks to earn potential commission from with the same amount of traffic. Just from changing the colour of a button!

So this simple test achieved-

  • An Improved click through rate to 52.25% from 41.46%
  • That is a 20% improvement over the original
  • An extra 850 affiliate link clicks


I hope you can see why you should be paying more attention to how many people actually click on your affiliate link once on your site.

We work hard to get traffic to our pages but many of us don’t pay the same care and attention to converting that traffic into cold hard cash.

So now you know how to improve click-through rate on your website.
