12 High-Value GEO Content Topics for 2025: Full Research Briefs
Generative Engine Optimization (GEO) is the discipline of structuring content so it gets cited by AI answer engines -- Perplexity, ChatGPT with browsing, Google Gemini, and Bing Copilot. Unlike traditional SEO, which optimises for ranked links, GEO optimises for the single authoritative excerpt an LLM surfaces from dozens of crawled sources.
The stakes are high. A 2024 SparkToro analysis found that over 60% of Google searches now end with no click. As AI answer boxes erode click-through rates, brands that get cited will win. This report identifies 12 high-value GEO content topics for 2025, each with a full research brief.
Topic 1: How to Optimize Content for AI Search
Monthly Volume: ~3,200 | Competition: Medium | Opportunity Score: 8/10
Target AI Platforms: Perplexity, ChatGPT Browse, Google Gemini
SERP Winner Examples:
- Search Engine Journal -- "GEO: Generative Engine Optimization Explained"
- Moz -- "How to Optimise for AI Overviews"
- HubSpot -- "AI Search Optimisation: Complete Guide"
Content Gap: Most existing content defines GEO but stops short of implementation. A step-by-step tactical guide with before/after content rewrite examples would dominate the cluster. No guide currently shows how to restructure an existing article to win AI citations.
Topic 2: GEO vs SEO: Core Differences
Monthly Volume: ~2,800 | Competition: Low | Opportunity Score: 7/10
Target AI Platforms: Perplexity, Bing Copilot, Gemini
SERP Winner Examples:
- Backlinko -- "GEO vs SEO: Complete Comparison"
- Neil Patel -- "Is GEO Replacing SEO?"
- Ahrefs -- "Search in the Age of AI"
Content Gap: Comparisons exist but none show concrete examples of content that wins traditional SERPs yet fails GEO, and vice versa. Side-by-side real specimens with before/after analysis would be uniquely valuable.
Topic 3: Prompt-Friendly Content Structure
Monthly Volume: ~1,400 | Competition: Low | Opportunity Score: 9/10
Target AI Platforms: Perplexity, ChatGPT, Claude
SERP Winner Examples:
- Content Marketing Institute -- "Writing Content AI Systems Love"
- Animalz -- "How to Write for LLMs"
- Clearscope -- "AI-Friendly Content Checklist"
Content Gap: No practical style guide specifies optimal header depth, paragraph length (researchers suggest 40-80 words), definition format, and list structure for AI extraction. A prescriptive, downloadable style guide would establish immediate authority.
Topic 4: Structured Data for AI Citations
Monthly Volume: ~1,900 | Competition: Medium | Opportunity Score: 8/10
Target AI Platforms: Google Gemini, Perplexity, Bing
SERP Winner Examples:
- Google Developers -- "Structured Data Intro"
- Yoast -- "Schema Markup Ultimate Guide"
- Schema.org -- "HowTo Schema"
Content Gap: Schema documentation is thorough, but no content correlates specific schema types with AI citation frequency. A study linking HowTo, FAQ, Article, and Dataset schemas to citation rates would be groundbreaking research.
Topic 5: FAQ Sections for AI Answers
Monthly Volume: ~2,200 | Competition: Low | Opportunity Score: 8/10
Target AI Platforms: All major platforms
SERP Winner Examples:
- Semrush -- "FAQ Schema: The Complete Guide"
- Ahrefs -- "FAQ Pages for Featured Snippets"
- Conductor -- "How to Structure FAQ Content"
Content Gap: FAQ advice targets featured snippets, not AI answers. The gap: how should FAQ answers be phrased -- direct answer first, elaboration second, caveats last -- to maximise AI extraction? Language-pattern research is entirely missing.
Topic 6: E-E-A-T Signals in the AI Era
Monthly Volume: ~4,100 | Competition: High | Opportunity Score: 6/10
Target AI Platforms: Google Gemini (primarily)
SERP Winner Examples:
- Search Engine Land -- "E-E-A-T and AI Overviews"
- Marie Haynes Consulting -- "E-E-A-T Deep Dive"
- Lily Ray -- "Expertise in the AI Search Era"
Content Gap: E-E-A-T content focuses on Google's traditional algorithm. The specific trust signals that influence Perplexity's and Claude's source selection have not been studied. Model-specific analysis would differentiate from generic guides.
Topic 7: Conversational Content Optimisation
Monthly Volume: ~1,600 | Competition: Low | Opportunity Score: 8/10
Target AI Platforms: ChatGPT Browse, Perplexity, Claude
SERP Winner Examples:
- WordStream -- "Conversational Marketing Guide"
- Drift -- "Conversational Content Strategy"
- Content Harmony -- "NLP-Optimised Content"
Content Gap: What reading level (Flesch-Kincaid ~60), sentence length (15-20 words), and vocabulary complexity maximise AI citation? NLP-backed, quantified research on this topic is entirely absent.
Topic 8: AI Answer Box Ranking Factors
Monthly Volume: ~2,600 | Competition: Medium | Opportunity Score: 9/10
Target AI Platforms: Google Gemini, Bing Copilot
SERP Winner Examples:
- Brodie Clark -- "AI Overview Trigger Analysis"
- Kevin Indig -- "Google AI Mode Deep Dive"
- iPullRank -- "AI Search Ranking Signals"
Content Gap: Research exists on AI Overview triggers, but not a ranked evidence-based list of factors determining which sources get cited within those boxes. A correlation study between content attributes and citation frequency would be the definitive resource.
Topic 9: Topical Authority for LLM Training Data
Monthly Volume: ~1,200 | Competition: Low | Opportunity Score: 10/10
Target AI Platforms: Claude, ChatGPT, Perplexity
SERP Winner Examples:
- Moz -- "Topical Authority: The Complete Guide"
- Holistic SEO -- "Topical Maps for Semantic SEO"
- PureLinq -- "Training Data and Search Rankings"
Content Gap: Almost no content explores how to structure a content hub specifically to influence LLM training corpora -- a fundamentally different goal from traditional topical authority with a longer time horizon. Lowest competition in this entire list.
Topic 10: Multi-Modal Content GEO
Monthly Volume: ~900 | Competition: Low | Opportunity Score: 8/10
Target AI Platforms: Gemini, GPT-4V, Claude with vision
SERP Winner Examples:
- Google Blog -- "Multimodal AI Search and Gemini"
- Smashing Magazine -- "Images in AI Search Results"
- Search Engine Journal -- "Visual Content in AI Answers"
Content Gap: GEO content is almost entirely text-focused. How do image alt text, caption quality, diagram labels, and surrounding paragraph text affect multi-modal AI citation rates? No empirical research exists on this question.
Topic 11: Local Business GEO
Monthly Volume: ~2,800 | Competition: Medium | Opportunity Score: 9/10
Target AI Platforms: Perplexity (local queries), Gemini, Bing
SERP Winner Examples:
- BrightLocal -- "Local SEO for AI Search Era"
- Sterling Sky -- "AI Local Pack Optimisation"
- Greg Gifford -- "Local GEO Signals"
Content Gap: Local GEO does not yet exist as a distinct optimisation category. Which Google Business Profile elements, NAP citation patterns, and review phrases get extracted by AI for local queries? High commercial value for agency services.
Topic 12: B2B GEO Strategy
Monthly Volume: ~1,800 | Competition: Low | Opportunity Score: 8/10
Target AI Platforms: Perplexity (business queries), Gemini, Bing Copilot
SERP Winner Examples:
- Forrester -- "B2B Buyers and AI Search 2024"
- Demand Gen Report -- "AI in B2B Buying Journeys"
- Gartner -- "AI Tools for B2B Research"
Content Gap: B2B buyers use Perplexity and ChatGPT to research vendors, but which content formats (case studies, comparison pages, ROI calculators) actually get cited by AI? A B2B-specific GEO framework is the missing resource in this space.

Strategic Recommendation
Start with Topics 9, 3, and 8 -- Topical Authority for LLMs, Prompt-Friendly Structure, and AI Answer Box Factors. These three offer the highest opportunity with manageable competition. Create a hub page titled "The Complete GEO Playbook" and publish each brief as an individual deep-dive. The internal linking will itself serve as a topical authority signal for AI systems.
Avoid Topic 6 (E-E-A-T) unless your domain has established authority. Moz, Search Engine Land, and Marie Haynes have too much of a head start on that keyword cluster. The window for GEO first-mover advantage is roughly 12-18 months. Move now.
