In one of the short #AskGooglebot video responses, Google's John Mueller said that changing a WordPress theme can directly affect a site's search ranking.
Mueller noted that changing a site's theme is often more than just a color update on a site. For example, the theme can often affect:
- the display of content, including headlines, text and images;
- page load time and speed;
- content parameters;
- internal links and site navigation;
- the use of structured data.
A good theme can help Google and other search engines understand your site.
