My marketing team is on me to fix Site Audit errors reported by Semrush and Ahrefs.
The error is: "218 pages have no hreflang and lang attributes"
This is a single language site - all in US English. I realize I can go into 218 pages and change < html > to < html lang="en" >. However, my full site is more than 2000 pages so I think the 218 count is just that site audit stopped there.
I'd like to just put a default in the page header for all pages. I see the syntax for hreflang alternate, but I don't think it's right for a single language site.
Is there a way for me to add a blanket default that makes semrush site audit know that all my pages are lang="en" ?
