One User Sina L.A asked to John Mueller about using the popular WordPress theme which is already used by many users, will it affect the site ranking in google in any way?
John Mueller responded on Twitter, no, he said “popularity of a theme has no effect on SEO at all.”
Popularity of a theme has no effect on SEO at all.
If you hear such generalizations, ask them “why”.

But just one month back in september 2021, when a user from India https://twitter.com/imnidhin3 asked about changing the wordpress theme :
Does changing the theme of a wordpress website doing good ( not the best in the industry, but not a bad one either) affect the ranking ?
If it does, at what degree ?
