Calculate monthly customer churn and revenue churn, and see what that rate means over a year.

See the Open Graph title, description, and image a link shows when it is shared, and what is missing.

Turn customers and plans into monthly recurring revenue, then break the month into new, expansion, and churned MRR.

Check your robots.txt for syntax problems, rules that block your own pages, and a missing sitemap line.

Check whether a page links to your site, and whether that link is dofollow, nofollow, sponsored, or ugc.
