Mobile-first indexing and how it can affect your rankings
Website designers who use WordPress really have no reason to worry. Unless you’re building sites on a very outdated theme or template, it should be using a responsive design. For the most part, pages built responsively will have most, if not all, of the same content on mobile and desktop. If you’re using two different templates for mobile and desktop, then you might have a problem. When I experience multi-templated sites, usually the mobile is a stripped down version with little content. That could have a huge impact on SEO.
