How do you test and experiment with different web design and content elements for SEO?

Well, I have set up my personal portfolio site a couple months back. I experiment with web design and content for SEO through A/B testing to compare variations using analytics tools like Google Analytics. This gives me insights on traffic and user behavior to refine strategies based on direct audience input. Btw, I encourage you all to go to my profile and check out my site - any feedback is welcome (especially critics!) :)

Select design elements to test, such as layout changes, color schemes, navigation menus, or call-to-action buttons. Choose content elements to experiment with, like headlines, meta descriptions, keyword density, or multimedia content. Determine which design or content elements positively or negatively affect SEO and user engagement. Continue to track performance and adjust based on long-term results and user feedback. Testing and experimenting with different web design and content elements for SEO involves a systematic approach to understand how changes impact search engine rankings, user engagement, and overall site performance.

When it comes to testing and experimenting with different web design and content elements for SEO, there are several strategies that can be employed to ensure the best results. A great way to start is by conducting A/B testing, where you can compare two versions of a web page to see which one performs better in terms of search engine rankings and user engagement. This can involve testing different layouts, color schemes, fonts, and calls to action. Another effective method is to utilize heatmaps and scroll maps to analyze user behavior on your website. This can provide valuable insights into how visitors are interacting with different design and content elements, allowing you to make data-driven decisions about what works best for SEO.

SEO as a process is driven through a lot of experimentation and custom implementations. Very often a lot of implementations are driven by notions like 'it's my gut feeling' or 'based on my experience and knowledge'. These notions can guide hypothesis formation through hunches or inclinations which can then be tested through systematic testing and inquiry. Once the objective is clear and a hypothesis is formed, then choosing success metrics is easy. For e.g., the objective is to recirculate users to more revenue generating pages after acquiring them through Search channels. You add a CTA as a related content headline and the hypothesis is to increase recirculation by 15%. The success metrics here can be CTR% and Conversion% or Bounce%.

Crafting a hypothesis is a critical step in the experimentation process, as it sets the direction for your SEO efforts. It's essential to base your hypothesis on data-driven insights and align it with specific, measurable, achievable, relevant, and time-bound (SMART) criteria. When selecting metrics, consider not only their direct relevance to the hypothesis but also their potential to provide deeper insights into user behavior and overall website performance. This thoughtful approach ensures that your tests are both strategic and actionable, leading to more meaningful improvements in SEO performance.

Once objective, hypothesis and metrics are in place, a testing method can be selected. There are mainly three testing methods namely, 1. A/B testing involves comparing two different versions of the page with similar elements with completely different designs. For e.g. testing two versions of the Homepage, one having more left to right aligned content and another having top to bottom aligned content. 2. Multivariate testing involves comparing different arrangement and combinations of elements on the same page. For e.g. comparing headlines, color combinations, widget placements, etc. on the same page. 3. Multifactor testing involves comparing different factors like user demographic mix, usage and behavior related factors, time zones, etc.

We will conduct an A/B testing experiment, where we randomly split our website traffic between two versions: a control group with the existing meta titles and descriptions, and a treatment group with the optimized meta titles and descriptions. The test will run for a minimum of 4 weeks to account for any seasonal or external fluctuations in traffic. We will use a statistical significance test to determine whether the results are due to chance or if the optimized meta titles and descriptions have a significant impact on click-through rate. The test will be conducted using Google Analytics and Google Tag Manager.

We will use Google Optimize to set up and run the A/B testing experiment, allowing us to easily create and manage multiple versions of our meta titles and descriptions. We will create a new experiment in Google Optimize and define the treatment group with the optimized meta titles and descriptions, as well as the control group with the existing meta titles and descriptions. We will then set up Google Analytics to track the click-through rate and conversion rate for each group, and configure Google Tag Manager to fire the correct meta title and description on each page. Finally, we will review and approve the experiment before launching it live on our website.

With Google Optimize out of commission, it leaves two other in my top preferred list of testing tools, namely VWO, Hotjar and Optimizely. There are some tools specific to platform and use case are available in the market like 1. Chartbeat to test multiple Headlines, 2. Firebase, UXCam and Apptimize for testing on Mobile Apps, 3. YouTube Studio has inbuilt feature for A/B testing for Videos. Choose the tool that best suits you depending upon the use case, useability, cost, technicality, support, ease of integration with your Analytics and other related tools.

Set up tips: 1. Crazy Egg: Add the tracking script to your site. Set up heatmaps to visualize user clicks and scrolls. Analyze data to adjust design, like button placement. 2. SEMrush: Create a project for your site. Use Site Audit to find SEO issues. Track keyword rankings before and after content changes. 3. Ahrefs: Add your site to the dashboard. Use Site Explorer for competitor analysis. Test different meta descriptions and monitor performance.

We will launch the experiment and allow it to run for the specified duration, collecting data on the click-through rate and conversion rate for both the treatment and control groups. Google Analytics will track the user behavior and send the data to Google Optimize, which will automatically record the results of the experiment. We will also use Google Tag Manager to fire events and track conversions, allowing us to measure the impact of the optimized meta titles and descriptions on our website's performance. After the experiment is complete, we will download the results from Google Optimize and analyze the data to determine if the optimized meta titles and descriptions have a significant impact on our website's metrics.

It can also be very helpful to have collected data ahead of the A/B test to act as a benchmark of the old design vs the new variants.

You would already have the data pre-test that would form the basis of the hypothesis and is important to validate the outcome which proved or rejects hypothesis. The factors that are not being tested should be kept unchanged and the test group (participants in the test) and control group (kept outside the test and serve as baseline for the test) should be carefully chosen. The duration of the test should allow collection of enough data that is statistically significant. Once these steps major steps are taken care of, careful monitoring during the testing period should ensure no errors or changes.

Before your run tests: Set Clear Goals: Define specific objectives like increasing click-through rates or reducing bounce rates. Identify Test Elements: Choose elements like headlines, images, buttons, or page layouts to test. Create Variations: Develop different versions of the chosen elements to compare. Run A/B Tests: Split your audience to show different variations and track which performs better. Then collect data: User Interactions: Use tools to track clicks, scrolls, and time spent on pages. Heatmaps: Visualize where users click and scroll on your pages. Surveys & Feedback: Gather user feedback on new designs or content. Analytics: Monitor metrics like bounce rates, conversion rates, and page views through web analytics tools.

Once the test is completed, the resulting data needs to be analysed and measured based on the success metrics. The statistical methods to ensure the success of the test and validate results include significance testing such as p-values and confidence intervals. Practical significance is also important along with the statistical significance, as SEO is not really an exact science. Many times the Hypothesis may be rejected, but the same test if repeated in a different time may prove the hypothesis right due to change in trends and user preferences.

Compare Metrics: Look at key performance indicators (KPIs) like click-through rates, bounce rates, and conversion rates before and after the test. Look for Statistical Significance: Ensure your results are statistically significant to validate the impact. Identify Patterns: Look for consistent patterns in user behavior across variations. Include User Feedback: Incorporate qualitative feedback from surveys or user comments. Do Segment Analysis: Break down results by user segments (e.g., new vs. returning visitors). Iterate: Use insights to make informed changes, then test again for continuous improvement.

In an SEO project for a healthcare website, I experimented with different types of schema markup, such as FAQ schema, product schema, & article schema, to enhance rich snippet visibility in search results. By implementing FAQ schema on certain pages, the website gained a featured snippet for a highly competitive keyword, which boosted organic traffic by 18%. Testing various schema markups helps search engines better understand your content, improving the chances of earning rich snippets & increasing your site’s visibility in search results.

Be aware that some A/B tools such as Google Optimize work by injecting code to change the design at page load time and this can affect page load time and may also affect the layout shift, so you may for example experience slight page flicker at load time and thus you need to ensure that running the A/B test itself does not affect the page experience itself.

Consider testing new designs and content on landing pages accessible only through paid media traffic (say, paid search). Ensure those landing pages are "no-index'd" so no organic traffic can find them. Once you are convinced the changes have been proven on the paid traffic audience, you can confidently migrate those designs to more public web locations. Even if the new designs cause a temporary disruption in your SEO rankings, it will only happen once, as opposed to every time you tweak your website's design.
