Content Gap Analysis
Scan the top 10 SERP results for every cluster keyword. ContentGem scores and prioritises every missing topic so you always know what to write next.
AI-Powered WordPress SEO Plugin
Build topical authority. Systematically.
ContentGem detects content gaps, maps your clusters, generates AI-powered SEO drafts, and fixes your internal links — all inside WordPress. No spreadsheets. No tab-switching. No tool stack.
Core capabilities
Everything topical authority requires
ContentGem replaces your entire SEO tool stack with one plugin. Gap analysis, AI drafts, competitor research, internal linking, cannibalization fixes, GSC insights — all inside your WordPress admin.
AI Draft Generation
Generate structured SEO drafts in one click using ChatGPT 5 or Claude — grounded in your gap data, not generic prompts.
AI Assistant
Chat, rewrite, generate meta descriptions, optimise titles, and surface semantic keywords — all from inside the WordPress editor.
Competitor Analysis
Analyse competitor domains, map their cluster architecture, and turn their gaps into your publishing opportunities.
Cannibalization Detection
Find posts competing for the same keywords. Get merge, redirect, or differentiate recommendations based on GSC data.
Search Console Insights
Near-win reports, CTR leaks, decay tracking, and indexation monitoring — pulled from your real GSC data inside WordPress.
How it works
From install to topical authority — step by step
ContentGem is designed to run as an ongoing system inside WordPress, not a one-off audit tool.
Install & configure
Upload to WordPress, connect your OpenAI or Claude API key, and optionally link Google Search Console.
Define your clusters
Tell ContentGem which topic clusters your site targets. It maps your existing posts and identifies pillar pages automatically.
Detect gaps & competitors
ContentGem scans the SERP for every cluster keyword and runs competitor analysis to surface every missing article — scored by opportunity.
Generate, publish & optimise
Generate AI drafts for priority gaps, fix internal links, resolve cannibalization, and monitor GSC decay — in one continuous workflow.
Why ContentGem
Built for WordPress.
Built for WordPress.
Not bolted onto it.
Most SEO tools live outside WordPress. ContentGem lives inside it — where your content actually gets written and published.
No tab-switching
Content gap analysis, competitor research, AI drafts, internal link management, and GSC monitoring are all in your WP Admin. No external dashboards, no copy-pasting between tools.
Your API key, your cost
ContentGem uses your own OpenAI (ChatGPT 5) or Anthropic Claude API key. You pay your AI provider directly at cost — no markup, no credit system, no surprise bills.
Data-driven, not hallucinated
Every content gap is grounded in real SERP data. ContentGem compares actual top-ranking pages against your content — it does not invent suggestions from thin air.
A system, not a one-off audit
ContentGem tracks your topical coverage percentage per cluster and updates it as you publish. You always know how close you are to comprehensive coverage and what to write next.
