Most SEO and content-audit tools share one uncomfortable habit: they hand your content to someone else's server, or send a crawler loose on your site — even before a page goes live. For public bodies, healthcare providers, or universities, that means a new data processing agreement, an external vendor to vet, and content leaving the building before it's even published. Often that's a procurement blocker before it's a technical one.

Migrating a classic Plone site to Plone 6 with Volto means more than moving records from one database to another. Free RichText HTML has to become structured Volto blocks, and that conversion is easy to get wrong quietly.
