Non-tech founder here — can I safely change my WordPress blog theme?

I recently took over the blog operations for our SaaS product. The blog was originally built with WordPress by a former tech team member. I’m not a developer, so I’m trying to figure things out as I go.

Now I’d really like to update the look and feel by switching to a new theme. But I’m worried — will changing the theme mess up our existing blog SEO or page structure?

Has anyone here done a theme change on WordPress and kept their traffic/results intact?

Would love to hear any tips or “watch out for this” advice from folks who’ve been through it!

Thanks so much 🙏

It’s currently using the Kratos theme.
