Are you running a SEO or Google Ads campaign? If yes, figure out how to improve them with Google Analytics insights. Understand your website metrics value and boost to sales, leads and revenue.
Best choice is create a subdomain, because each trainer Will have a different content and layout. But for Google each subdomain is a new website, no share relevance between them. If you can use a page model for each trainer, you can use directory structure such as domain.com/trainers/name, so you will distribue link juice across pages, improving website architecture.
Metrics that you are analyzing are percentage, It means if integers values decreased probably percentages will increase. So, you need to understand what are website long-terms top ranking. If you provided information contents without a call-to-action or your blog user experience is no good, probably your blog wil keep a low performance.
