Case Study
Use Case: Content Gap Analysis for SEO / LLMO
Problem: How do you stand out when everyone chases the same keywords?
Everyone uses the same tools and competes for the same keywords. What’s often missing is relational insight and a holistic understanding of the context.
Solution: Target the gaps for maximum informational gain.
Visualize the current informational supply and identify the main topical clusters you should dominate to gain topical authority.
Find the content gaps between those clusters and use built-in AI to generate briefs that bridge them.
What is Content Gap Analysis? Try It Now
Use Case: KeywordGraph inside your LLM
Problem: LLMs write generic SEO without real data.
Ask ChatGPT to write an SEO-friendly article and you’ll get generic output that will be penalized by both search engines and LLMs.
Solution: Plug the KeywordGraph MCP server into your LLM client.
Our SEO MCP server gives your LLM live access to search intent, SERPs, competitor content comparison and detailed SEO reports. It builds a knowledge graph under the hood, so every output is grounded in real relational data.

Use Case: Building a graph of search intent
Problem: Most tools focus on SERPs, not on intent.
Most tools base their advice on existing content and ignore the search intent. They give generic summaries and shallow insights.
Solution: Graph the keywords people actually use.
KeywordGraph extracts Google’s “related search phrases” and builds a graph of the thought patterns behind your query. Target those for best results.

Use Case: Better insights with SEO visualization
Problem: Spreadsheets hide patterns.
Most SEO tools give you spreadsheets that are hard to analyze and lack the visualization to reveal relational patterns.
Solution: Graph your keyword exports from Ahrefs, Semrush and GSC.
Export keywords from your favorite SEO tool as a CSV and import them into KeywordGraph. Build a knowledge graph and discover the topical clusters, keyword combinations, and content gaps that your current tools won’t surface.

Typical Workflow for SEO Keyword Generation
First, add the keyword query that you want to explore. For instance “seo tools”.
Visualize the main topical clusters and patterns in search intent to understand what people search for.
Explore specific keyword relations related to your original query. The “keyword generator” relation looks like an interesting one.
Visualize the search results for the selected query to see what people actually find. Not so much on “keyword generator”.
Compare the graphs to see what’s in search intent but missing in the SERPs. The “keyword generator youtube” combination pops up.
Use the “missing keywords” feature to find gaps in your competitors’ messaging — and target them for maximum informational gain.
How KeywordGraph Works
1. Represent search intent or search results as a knowledge graph
Using our peer-reviewed methodology, we visualize a network of keyword co-occurrences that reveals the most prominent patterns, top keywords and topical clusters.

2. Maximize informational gain by targeting content gaps
Network graph visualization of keywords reveals the main topical clusters and the gaps between them. Content that targets these gaps ranks higher on Google and gets cited more by LLMs because it adds the most informational gain to the discourse.
3. Compare search intent and search results to find what’s missing
Overlap the intent and results graphs to find the difference between them. You will see what people search for but don’t yet find — and exactly which keyword relations fill that gap.
