Is your website in need of a fresh look? If it’s powered by WordPress, changing its layout and appearance is as simple as installing a new theme. With over 12,000 themes available in the WordPress repository, you have plenty of options to choose from.
However, while switching to a different theme can revitalize your website’s appearance, it may also impact your site’s search engine rankings. Many websites experience a drop in rankings after a theme change, potentially moving from the top of Google’s first page to the second or third.
Fortunately, by taking some basic precautions, you can change your website’s theme while preserving its hard-earned SEO performance. Let’s learn how.
How to Change WordPress Theme Without Losing SEO
Changing your WordPress theme can impact your site’s SEO, but with proper precautions, you can ensure minimal disruption. Here’s a step-by-step guide to changing your WordPress theme without losing SEO:
Quick Navigation
1. Preserve Custom Code and Content in Theme Files
When switching your WordPress theme, it’s important to safeguard any custom code or content that has been manually added to your theme files. This is often referred to as “hard-coded content,” and losing it can have unintended consequences for your website’s functionality and SEO.
Hard-coded content refers to any HTML, scripts, or other code manually added to your theme files, rather than being managed through the WordPress admin interface.
For example, you might have added custom tracking codes, structured data for SEO, or special text and images that appear site-wide. Unlike regular posts or pages stored in the WordPress database, this content is tied directly to your theme’s code.
If your hard-coded content includes important SEO elements, such as meta tags, structured data, or even keyword-rich footer text, losing this content during a theme change could negatively impact your site’s search engine rankings. Search engines rely on this content to understand and index your site, so it’s vital to ensure it remains intact.
Before installing a new theme, take the time to review your current theme’s files for any custom code or content you’ve added. Common files to check include header.php, footer.php, functions.php, and any other template files where you might have inserted custom elements. Copy this code and store it securely so you can reapply it to the new theme if necessary.
2. Check Plugin Compatibility
Another important consideration before changing the theme is ensuring that your plugins will continue to function properly. Not all themes and plugins are fully compatible with each other. A plugin that works perfectly with your current theme might run into issues with a new one, potentially disrupting your website’s functionality and even affecting your SEO.
Plugins often add critical features to your website, such as SEO tools, caching, or security enhancements. If a plugin is incompatible with your new theme, it might not work as expected—or at all. This could lead to broken features, a poor user experience, or a negative impact on your site’s search engine rankings.
To avoid these issues, take the following steps before switching themes. Start by researching the new theme. Check the documentation or support forums for any known compatibility issues with your key plugins.
Popular themes often have extensive user communities where these issues are discussed. Next, test in a staging environment. Set up a staging version of your website where you can install the new theme and test all of your plugins without affecting your live site. This is the safest way to identify any compatibility problems before making changes to your main site.
If you’re unsure about compatibility, reach out to the developers of the plugins you rely on. They may offer insights or updates that ensure compatibility with your new theme. However, if a critical plugin is incompatible with your new theme and no solution is available, you might need to find an alternative plugin that offers similar functionality.
3. Preserve URL Structure
Keeping your website’s URLs consistent is crucial to preserving your site’s search engine rankings during a theme change. Search engines index and rank content based on URLs, which serve as the unique addresses for your posts and pages. If a URL changes, search engines must rediscover, re-index, and re-rank the content, which can take time and potentially harm your rankings.
While most WordPress themes won’t alter your website’s URLs—since URL structure is typically controlled through the “Permalinks” settings in your dashboard—there are some exceptions. Certain themes may introduce a different URL format by default or give you the option to modify the structure. Accidental changes to your URLs can result in 404 errors and negatively impact your SEO.
To prevent this, verify that your new theme doesn’t override your existing URL structure. After applying the theme, double-check your website’s URLs to ensure they remain unchanged. Additionally, using a broken link checker after the theme change will help identify and fix any 404 errors.
4. Ensure Indexing and Crawlability
Maintaining visibility in search engines requires careful attention to how your site is crawled and indexed, especially after a theme change. Any changes that disrupt this process could lead to a drop in rankings. Start by checking that your new theme doesn’t accidentally set any important pages or posts to “noindex,” which would prevent them from being indexed by search engines.
It’s also a good idea to review your robots.txt file to ensure that no essential parts of your site are inadvertently blocked from being crawled. Additionally, confirm that your XML sitemap is still functioning correctly and includes all relevant pages. A well-maintained sitemap helps search engines discover and index your content efficiently.
After implementing the new theme, use Google Search Console to monitor how your site is being crawled and indexed. Look out for any errors or warnings that could indicate issues. Ensuring that your site remains easily crawlable and properly indexed will help maintain your search engine rankings after the theme change.
5. Test Load Times
After applying the new theme, it’s crucial to test your website’s load times to ensure it continues to perform well in search engine rankings. A new theme can significantly influence how quickly your website loads, as some themes are optimized with cleaner, more efficient code, while others may slow down your site due to poorly optimized or excessive code.
Site speed is a key factor that search engines consider when ranking websites. Faster load times contribute to a better user experience, which in turn can positively affect your SEO. Conversely, switching to a slower theme can result in a drop in rankings as search engines prioritize sites that provide a faster, smoother experience for users.
To assess your website’s speed after a theme change, use a reliable speed testing tool. Google’s PageSpeed Insights is a popular and free tool that not only measures how quickly specific parts of your site load but also provides suggestions for improving load times.
Since most speed testing tools evaluate load times at the page level, focus on testing key pages like your homepage and other high-traffic areas. Testing load times immediately after switching themes allows you to address any performance issues before they negatively impact your site’s SEO.
6. Check User Experience
The design and functionality of your website play a crucial role in how users interact with your content, which can indirectly influence your search engine rankings. A well-structured, intuitive theme helps users navigate your site with ease, reducing bounce rates and improving engagement—both of which are important signals to search engines.
Make sure the new theme maintains a logical and user-friendly navigational structure, allowing visitors to quickly find the content they’re looking for. Pay attention to mobile responsiveness, ensuring the theme adapts seamlessly to various screen sizes and devices, as mobile traffic constitutes a significant portion of web users today.
Readability is another critical aspect. The new theme should use clear fonts, appropriate color contrasts, and a clean layout to ensure content is easily digestible. Poor readability can frustrate users, leading to higher bounce rates, which could negatively impact your rankings.
Finally, after launching the new theme, test the user experience thoroughly. Use tools like heatmaps and session recordings to observe how visitors interact with the new design, and make adjustments if necessary. A positive user experience is key to retaining visitors and maintaining strong search engine rankings.
7. Monitor Traffic Post-Launch
Keeping a close watch on your website’s traffic after implementing a new theme is essential to ensure everything continues to perform smoothly. Significant changes in design or functionality can sometimes lead to unexpected drops in traffic, so monitoring these metrics will help you catch and address any issues early.
Use tools like Google Analytics to track key indicators such as overall traffic, bounce rates, and user behavior. Pay particular attention to any significant declines in organic traffic, as this could signal an issue with how search engines are interacting with your site post-launch.
Consider setting up alerts for sudden drops in traffic or spikes in bounce rates, which could indicate a problem with the new theme or its impact on user experience. By analyzing this data and making necessary adjustments, you can help ensure that your website maintains its search engine rankings and continues to perform well after the theme change.
