A duplicate H1 means several pages use exactly the same main heading. Visitors and search engines then see pages that look alike from the top.
Pages with the same heading compete for the same subject. It often means the heading comes from a template instead of from the page.
Snaglist compares the first H1 of all indexable pages, without regard to capitals, and lists every page whose H1 also appears on another page.
Snaglist runs this check and 43 others on every page of your site, every week. 14 days free, no credit card needed.
