Indexer Monitor · case study

The context

Indexer Monitor is an in-house SaaS SEO suite. The principle: plug the SEO practitioner directly into their own Google data, in a single interface, rather than into third-party estimates, and keep that data inside the user browser through bring-your-own API keys, never stored on a server.

The approach

• 13 tools in one interface: SEO audit (40+ criteria per page), multi-page crawler, Search Console, GA4 Analytics, PageSpeed and Core Web Vitals history, SERP tracker, index checker, force indexing, IndexNow, Safe Browsing, opportunities and multi-domain management.
• Plugged directly into 8 Google services over OAuth2: Search Console, GA4, Indexing API, URL Inspection, Custom Search, Safe Browsing, PageSpeed and more.
• Natural-language AI assistant: the user plugs in their own Gemini key, so data and key both stay with them and are never stored server side.
• Automatic quick-win detection: keywords sitting on page 2, pages with high CTR potential, cannibalisation, ranking drops, all prioritised by potential traffic.
• Professional audit reports exportable to PDF, multi-client management, and a free instant public SEO audit with no sign-up.
