What we fix
The four problems every SaaS marketing team hits
PAIN 02
Programmatic SEO pages aren't indexing
Bulk URL inspection across thousands of programmatic pages. We surface the patterns Google is rejecting (thin content, soft 404s, duplicate clustering) so you can fix at the template level.
PAIN 03
Competitors keep winning ChatGPT recommendations
Track which competitors get recommended for your category queries in ChatGPT, Gemini, Perplexity and Claude. Reverse-engineer why their content gets cited.
PAIN 04
Your blog ranks but doesn't convert
Pair rank tracking with GA4 product analytics. See which keywords drive trials/signups, not just sessions – and double down on what works.
