Hi. I checked my site with Nibbler, and found the same alert "empty text links" on all pages, because of the social icons in the footer. When I asked squarespace about this they said:
SEO marketing tool reports about site errors are intended for use with custom-coded sites, not sites built on content management systems (CMS), like Squarespace, so they can return reports that don't apply to your site. We can provide some insight into understanding Google SEO emails and console errors, but we can’t investigate results from other third-party tools.
Is this right?
