There are so many things to consider when it comes to changing WordPress themes. If you’re working with an established site, you’re probably wondering: will changing your WordPress theme affect your SEO?
Yes, changing your WordPress theme will affect your SEO, potentially to a great extent. Your theme impacts your design, site speed, content formatting, and structured data—all important factors for SEO. However, there are ways to maintain or even improve your rankings after switching themes.
In this article, we’ll cover exactly how changing your WordPress theme can impact your SEO, and what you can do to stay in Google’s good graces after the switch.
Your WordPress theme is the backbone of your site. It literally dictates everything you see on the frontend of your site—not to mention what’s going on under the hood.
With that in mind, let’s take a look at some of the specific ways a new WordPress theme can affect your SEO.
User experience is one of the most important considerations for SEO.
If your website is difficult to read or navigate, many visitors will bounce back to the search results—indicating to Google that your website is not helpful or user-friendly.
A WordPress theme is a lot more than a design, but design is indeed an important consideration.
Is your new theme well-designed? Is it readable? Is it mobile-friendly?
Your WordPress theme can make or break your site’s performance.
Some themes are absurdly complex and bloated. They may look pretty on the surface, but when Google sees that your site takes 8+ seconds to load, your rankings are going to plummet.
On the other hand, if you upgrade to a lightweight theme that reduces your page load times to two seconds or less, you may see a nice boost.
Your WordPress theme doesn’t affect your content itself, but it does determine how it’s formatted.
It’s particularly important that your theme uses the proper heading structure:
Generally, the only Heading 1 (h1) text on your page should be the main title, i.e. the name of your post. Any subheadings should be formatted as h2, with h3 below that, and so on.
Most high-quality premium themes handle this correctly, but it’s always a good idea to check.
Many themes offer built-in SEO features to help you manage your page titles, meta descriptions, and structured data for rich search snippets.
As convenient as this may be, switching themes means you lose all of that custom data—which can really hurt your SEO.
That’s why we recommend using a plugin like Yoast SEO to manage your SEO data, rather than relying on your theme.
Now that we’ve seen some of the ways changing your WordPress theme can affect your SEO, let’s talk about what you can do to maintain your search rankings with a new theme.
Your quest to maintain (or improve) your rankings should begin with your initial theme search.
An SEO-friendly theme formats content correctly with well-organized code, provides a pleasant user experience, and loads quickly.
Here are three specific suggestions:
GeneratePress is an ultra-lightweight, SEO-friendly theme that you can customize for virtually any site. It’s known for its performance, and I’d say it’s one of the fastest WordPress themes in existence.
Because it’s so versatile, it’s hard to encapsulate the visual style of GeneratePress in a single image. Instead, check out their site library here to see a bunch of demos that you can use to start your site.
Astra is another lightweight, SEO-friendly theme that’s highly customizable. Like GeneratePress, it has a gallery of starter sites that you can import into your site with a single click.
StudioPress is a longtime leader in WordPress theme design, and their Genesis framework ensures that all of their themes meet the same high SEO standards.
A key step to help you maintain your search rankings is to simply test your new theme ahead of time.
Specifically, I recommend creating a staging site to make sure your new theme is properly formatted and offers a good user experience. For more details, check out our tutorial on how to change WordPress themes on a live site.
You can use the element inspector on Chrome and other modern browsers to make sure your headings are properly formatted. Just right click one of your headings, then click “Inspect.”
Remember: the title of a post should be formatted as h1. All other headings should be h2 or lower.
You can also test your site speed using a tool like GTmetrix.
If you find that your site takes longer than two seconds to load with your new theme, it’s worth making some optimizations to improve your performance.
Google uses page speed as a ranking signal, meaning that when all other factors are equal, a faster website will rank higher in the search results.
Here are some key steps you should absolutely take to improve your performance:

If your current theme handles your SEO and schema.org structured data, now is the perfect time to future-proof your site by switching to a plugin.
I use the free Yoast SEO plugin on all of my sites, and I never have to worry about losing my SEO titles, meta descriptions, or schema data when I change my WordPress theme.
For a full guide to setting up the Yoast plugin, check out our full WordPress SEO tutorial.
Changing your WordPress theme inherently affects your SEO because it fundamentally alters all of the pages search engines have indexed from your site.
Generally, as long as your new theme is solid and you’ve made the right optimizations, you should be able to avoid any long-term setbacks—but there’s always a risk of short-term problems.
With that in mind, it’s a good idea to stick with your new theme for as long as possible. If you choose an SEO-friendly theme that suits your brand and commit to using it for the long haul, you won’t have to worry about this again for a long time.
So, will changing your WordPress theme affect your SEO? Yes—but you can easily maintain or even improve your rankings by making a few smart decisions in the process.

Does CSS errors and issues also have any impact in terms of ranking? I am specifically asking about the errors shown during CSS Validation report.
I'm done changing WordPress themes. I use generatepress for everything now and if they ever stop updating it I'm just screwed I guess
my theme is divi
so what can id do ?
my code to text ratio is low but my speed test score is fine
is it ok to build a new site and redirect all of my page to that ?
Thank you very much.
Sure thing!
If one had to re-create their entire website using another theme like generatepress. So everything will look identical but the theme platform changes from theme A to generatepress theme backend. Will SEO be effected into the negative?
This is impossible to answer definitively, but theoretically if the content and structure are kept largely the same, you should see minimal impact. It’s normal to see some short-term fluctuations with a theme change, but if you’re moving to a well-optimized and properly coded theme (like GeneratePress), the long-term net effect should only be positive.
Hey I have a question. Does making and activating a child theme affect (drop) SEO ranks of an already ranking website that is live? A big time question for me. Please guide.
(I need to make a child theme to add some custom codes).
Hi Anchal,
Great question. No, creating and activating a child theme should have no impact on your SEO, because the structure and layout of your website will be unchanged. It’s essentially like you didn’t switch themes at all. (Here’s our tutorial on creating a child theme if you or anyone else are interested!)
Thank you so much for replying.. So does this mean, it is the change in designs and layout, that actually affect ranking while switching themes? Please confirm.
That's correct. Because creating a child theme doesn't affect the front end of your site (what Google and your visitors see), there should be no impact on SEO.
I recently, finally, got everything moved to WordPress .org. I feel incredibly silly not completely understanding what the difference was. Anyway, I went with the theme I had before. It worked fine. But now the menu is acting weird. If you are on the phone version you click it and only scroll a little. But nothing of the menu comes up. I went searching for it and had to scroll all the way to the bottom. Well, that's inconvenient. It hadn't done that when I was on WordPress .com. why would it do that? On the dashboard of the theme customizer it's not like that.
I've changed my WordPress theme over 10 times now, It really does affect my traffic, I've been trying to gain my ground again, but it seems it's not working.
great
