Verify What Crawlers Actually Render
SPA frameworks can serve crawlers empty shells while users see full pages. The audit checks the rendered output externally — titles, content, links — exactly as a search engine receives it.
SEO for SaaS
Your product is technical. Your SEO debt should not be.
SaaS sites accumulate a particular kind of SEO debt: marketing pages on one framework, docs on another, a blog on a third — plus JavaScript rendering that hides content from crawlers and programmatic pages that index as thin duplicates. An external audit shows what Google actually receives across all of it.
SEO Focus: JS rendering, docs and feature page indexing, programmatic page quality

Docs and Feature Pages Are Acquisition Channels
Developers search error messages and how-tos; buyers search feature comparisons. Index coverage and content analysis confirm these high-intent pages are indexed, deep, and internally linked from your main structure.
Programmatic Pages: Scale Without Thin-Content Penalties
Template-generated landing pages multiply fast and duplicate faster. Duplicate metadata detection and content depth checks show which programmatic pages add value and which dilute the domain.

Frequently Asked Questions
Our site is a React/Next.js app. Does that hurt SEO?
Only if crawlers receive unrendered or incomplete output. The audit shows what an external crawler actually gets, so you know whether your rendering strategy works before rankings tell you.
Should docs be on the main domain or a subdomain?
On balance, a path on the main domain consolidates authority. Either way, the audit verifies docs pages are indexable and linked from your primary structure.
Why did our programmatic pages stop ranking?
Usually thin or near-duplicate content across the template. The audit identifies which pages cross that line so you can consolidate or deepen them.
