Webflow currently generates an HTML timestamp that is the same for all pages. From what I've read, this isn't the best SEO practice especially if you have pages that are more "active" than others. The XML sitemap generated by Webflow doesn't include publish date/time.
Although you can paste in your own sitemap with publish date/time it would then possibly contradict the HTML timestamp which probably isn't the best plan.
Could we have the sitemap include publish date/time and not have the HTML timestamp? Or better yet a way to publish just one page at a time:)
