Hello...
Please kindly recommend how to fix this issue. Thanks.
After diagnosis by some SEO tools, found that my homepage, other pages and all individual post pages contained 6-7 H1 tags as following examples:
Home page (a static page): 6 H1 tags; sitename, tagline, page title, recent posts, categories, bookmarks
Other individual post: 7 H1 tags; sitename, tagline, post title, post navigation, recent posts, categories, bookmarks
