In this blog post, we will explain how to use SEO A/B testing to increase organic traffic and share some best practices and tips to make your tests successful.


What is SEO A/B Testing?

SEO A/B testing involves creating two versions of a webpage, the original (A) and the variant (B), to compare their performance. By measuring the impact of specific changes on search engine ranking and organic traffic, you can make data-informed decisions to optimize your website.


How does SEO A/B testing work?

SEO A/B testing works by creating two or more variants of a web page or an element on a web page and showing them to different segments of your audience. You can use tools like Google Optimize, Optimizely, or VWO to create and run SEO A/B tests on your site.


The tools will randomly assign each visitor to one of the variants and track their behavior and interactions on your site. You can then analyze the data and compare the results of each variant to determine which one is the winner.


The winner is the variant that has the highest score for the metric you are optimizing for. For example, if you are testing different headlines for your blog post, the winner is the headline that has the highest click-through rate from search engines.


Identify your goal and hypothesis

The first step of SEO A/B testing is to identify your goal and hypothesis. Your goal is what you want to achieve with your test, such as increasing organic traffic, reducing bounce rate, or boosting conversions. Your hypothesis is what you think will help you achieve your goal, such as changing the title tag, adding a video, or using a different color for the button.


For example, your goal could be to increase organic traffic to a specific landing page by 10% in 30 days. Your hypothesis could be that adding a keyword-rich title tag and meta description will improve your click-through rate from the search results and drive more visitors to your page.


Choose your test page and variants (Selecting Testable Elements)

The next step is to choose your test page and variants. Your test page is the web page that you want to optimize for your goal. Your variants are the different versions of your test page or an element of your test page that you want to compare.


For example, if you want to test the impact of title tags and meta descriptions on organic traffic, your test page could be any landing page on your website that has a low click-through rate. Your variants could be:

  1. Variant A: The original title tag and meta description
  2. Variant B: A new title tag and meta description with the main keyword
  3. Variant C: A new title tag and meta description with the main keyword and a benefit
  4. Variant D: A new title tag and meta description with the main keyword and a call to action
