Common questions from Programmatic SEO users
What's the page-count limit?
Free tier: 100 pages. Starter: 1,500 per site. Pro: 15,000 per site. Above that, contact us — we work with programmatic SEO sites at 100k+ scale on custom plans.
Do you handle the duplicate-content / template patterns common in programmatic SEO?
Yes. We embed the semantic content of each page, not the template chrome. Pages with the same template but different topics are correctly distinguished.
Can this run in a build pipeline that ships nightly?
Yes — our JSON API + webhook push is purpose-built for it. Pro tier includes daily auto-rescans with content-hash diffing so you only re-process pages that actually changed.
