Keyword Clustering and Topic Research That Builds Topical Authority

Why SDM

A Research Process Built for Search Engines and Language Models

Google and AI assistants both read your site the same way. They look for depth around a subject, not a pile of disconnected phrases. SDM structures your keyword data so both audiences find the same clear answer, your brand.

🧩

Semantic Clustering Method

We group thousands of queries by meaning and search intent instead of volume alone, using cosine similarity and n gram analysis to find the true shape of your niche.

πŸ•ΈοΈ

Entity and Knowledge Graph Mapping

Every cluster is linked to the named entities, people, places, products, and concepts, that Google and large language models associate with your industry.

πŸ€–

Ready for AI Overviews

Our briefs are written so your content can be pulled into AI Overviews, ChatGPT answers, and Gemini responses, not just ranked ten blue links deep.

🎯

ICP Aligned Prioritization

Clusters are scored against your ideal customer profile, so effort goes first to the topics your actual buyers search, not vanity keywords with empty traffic.

🌐

Global Market Coverage

We research in any language and locale your customers use, adjusting for regional phrasing, local competitors, and country specific search behavior.

Common Questions

Frequently Asked Questions About Our Keyword Research Service

What makes topic research different from ordinary keyword research +
Ordinary keyword research produces a list ranked by volume. Topic research groups those keywords into clusters built around search intent and entities, giving your content team a full map of a subject rather than isolated terms to chase one at a time.
Do you research keywords in languages other than English +
Yes. Our worldwide research process covers any language and locale your customers use, including region specific phrasing, local competitor analysis, and multilingual entity mapping for global brands.
How long does a full topic research project take +
A Starter package is usually delivered within 7 business days. Growth and Enterprise projects, which cover larger niches and multiple markets, typically take 2 to 4 weeks depending on scope.
Will this help my content appear in AI Overviews and chat assistants +
Our briefs are written with answer engine optimization in mind, including the entities, structured data, and information depth that generative search tools look for when selecting a source to cite.
Do you also write the content or only deliver research +
This service focuses on research, clustering, and briefs. If you need the content written as well, our SEO content strategy team can take the same briefs straight into production for you.
Can this service work alongside an existing content team +
Yes. Most clients keep their own writers and simply plug our topical maps and briefs into their existing workflow, so nothing about your current publishing process needs to change.
What data sources do you use for clustering +
We combine search volume tools, SERP analysis, competitor crawling, and natural language processing models to identify semantic relationships that simple keyword tools miss on their own.
