GEO Strategy for Multi-Authority Sites

If you’re running a content site that spans multiple topics—whether it’s a media publication, a niche authority hub, or an enterprise blog—you already know how hard it is to keep search performance consistent across the board.

But what happens when search isn’t the goal anymore?

Welcome to Generative Engine Optimization (GEO), where your objective isn’t just traditional rankings—it’s getting quoted, summarized, and used by AI.

In this post, we’ll break down how to structure and optimize multi-authority or multi-topic sites for better visibility in AI-generated answers across tools like ChatGPT, Perplexity, Claude, and Gemini.

Why Multi-Authority Sites Struggle in GEO

The challenge with large content networks is context dilution.

AI models—especially when summarizing or quoting—don’t always know what your site specializes in. If your content covers 12 different verticals, it’s hard for an LLM to pin down what you're authoritative on.

That’s why even massive publishers get out-ranked in AI summaries by smaller niche blogs.

To solve this, you need GEO clarity per vertical, and a structure that makes your site parseable by models.

Step 1: Create Topical Hubs with Structured Content

Divide your site’s GEO presence into clear topical silos. Each should have:

  • A cornerstone hub page
  • 5–10 subpages with strong internal links
  • A clear tone and prompt style (testable via Prompt Simulator)

Tip: Each hub should be designed to answer a specific cluster of prompts, not just cover a keyword.

For example:

  • If you have a section on “AI tools,” make sure it can answer prompts like:
    “What are the top AI tools for video editing?”
    “Best free AI tools for content creators in 2025”

  • If you have a section on “Freelancing,” build content that answers:
    “How to invoice international clients as a freelancer”
    “Best platforms for freelance developers”

Step 2: Structure Content for Machine Parsing

It’s not just about writing—it’s about how you structure that writing.

Use:

  • Semantic headings (<h2>, <h3>)
  • FAQ schema (see full guide)
  • Bullet points and bolded facts
  • Short, skimmable paragraphs

Avoid long, meandering intros or unrelated tangents. AI will skip over these entirely.

You can test which sections of your page are actually used by running prompts in the Mention Extractor and reviewing mention context.

Step 3: Assign Model-Friendly Author Personas

One major advantage of large sites is access to multiple authors. Use this to your benefit—create clear author identities that align with topical expertise.

For example:

  • Lisa – AI and Automation
  • Mike – Ecommerce Strategy
  • Raj – SEO + Web Analytics

Not only does this help users, but AI models are trained to associate names with trust signals. In fact, persona-anchored content often performs better in LLM citations.

Use the GEO Content Strategy Guide to build a per-author AEO plan.

Step 4: Deploy Internal Linking Like an Answer Engine

Traditional SEO links for authority. GEO links for explainability.

Use internal links as a way to build a narrative structure across your site. Think of your content as nodes in a knowledge graph.

Example:

You’re giving LLMs a roadmap.

Step 5: Use Prompt Testing to Discover Weak Spots

The best thing about GEO? You don’t have to guess what works.

Test prompts using PromptSeed’s tools:

  • Does your article get paraphrased in the answer?
  • Does your brand or site name get mentioned?
  • Are competitors showing up instead?

If not, rewrite your summaries, meta sections, and headers to more clearly reflect the answer a user would want.

Run tests weekly to monitor how visibility shifts over time—especially after publishing new content clusters.

Step 6: Run Section-Based Audits with the Page Auditor

The upcoming GEO Page Auditor lets you scan specific URLs and identify:

  • Which sections are likely to be used in AI answers
  • Which schema types you’re missing (FAQ, HowTo, Product)
  • Where clarity or scannability is lacking
  • Suggested schema snippets for inclusion

This is a critical tool for large sites, where not every article can be manually reviewed.

Final Thoughts: Clarity Beats Coverage

In traditional SEO, the bigger the site, the better. More coverage, more topical authority.

But in GEO?

Clarity wins.

A small, tightly optimized site focused on one thing will often beat a large one with scattered coverage. But if you structure your content and link it wisely, multi-topic sites can dominate the AI answer space.

The key is to stop optimizing for “pages” and start optimizing for answers.
