About a year ago Google started sending me emails for mobility and breadcrumb errors, like viewport not set, text too small to read, data-vocablulary.org deprecated, etc.
Over the summer I fixed the entire site of about 400+ pages by updating a few templates (isn’t MODx grand). Now every couple of months Google will email out another group of pages pointing out the old errors that don’t exist anymore. Google actually shows a last crawled date for these pages at over a year ago.
Could there be a problem with my sitemap which is generated by the default GoogleSiteMap snippet? It seems like the <lastmod>
tag doesn’t seem to update when a template is edited. Or is there some way to tell Google SearchConsole that the whole site has been updated and needs to be re-indexed before they look for more errors.
