Four practical metrics to measure Generative Engine Optimization — AI citation rate, share of voice, referral traffic from AI engines, and Bing/Google AI performance reports.

2026-08-28T00:00:00Z https://geohandbook.io/articles/earned-media-89-percent/

89% of LLM citations come from earned sources, not owned websites. Here's what that means for how marketers and webmasters should allocate GEO effort.

A pragmatic 2026 take on llms.txt — what it is, what the evidence says, and why the file is still worth shipping even after Google's dismissal.

AI bots are 51%+ of global internet traffic. Two-thirds of AI-driven sessions never reach Google Analytics. Here's a measurement framework that survives those blind spots.

LLMs organize knowledge as graphs of entities. If your brand isn't a clean node in that graph, you compete with better-defined sources like Wikipedia and Wikidata — and lose.

A pragmatic take on structured data for GEO in 2026 — which schema types actually move citation rates, and how to validate them in CI.

40% of ChatGPT answers use live retrieval. The other 60% come from training-data patterns you can't influence overnight. Here's the realistic playbook.

2026-09-13T00:00:00Z https://geohandbook.io/articles/google-may-2026-ai-update/

The biggest update since AI Overviews launched. Inline citations, expanded coverage, deeper reasoning — and a shift from rank to citation-worthiness that finally makes GEO measurable.

2026-09-15T00:00:00Z https://geohandbook.io/articles/answer-first-writing/

Why "answer-first" paragraph structure is the highest-leverage change you can make for GEO — and how to rewrite an existing page in ten minutes.

2026-09-16T00:00:00Z https://geohandbook.io/articles/reddit-hidden-influence/

Two 2026 studies quantify Reddit's outsized role in AI answers. The visible-citation number is the smallest number that matters.

2026-09-17T00:00:00Z https://geohandbook.io/articles/perplexity-source-selection/

Perplexity visits ~10 pages per query, reads them in full via a URL-fetcher, and applies a three-layer reranker. Here's what actually gets a page cited.

2026-09-18T00:00:00Z https://geohandbook.io/articles/search-console-verification/

Two verifications drive the entire AI search visibility loop: Bing for ChatGPT Search, Google for AI Overviews and AI Mode. Both take one DNS TXT record and 15 minutes. Here's the exact playbook.

2026-09-18T00:00:00Z https://geohandbook.io/articles/perplexity-reddit-playbook/

Perplexity cites Reddit in 46.7% of B2B SaaS responses — but the mechanics of getting cited by Perplexity from Reddit differ meaningfully from getting cited by ChatGPT. Here is the engine-specific playbook.

2026-09-18T00:00:00Z https://geohandbook.io/articles/perplexity-model-tiers-and-modes/

Sonar, Sonar Pro, Sonar Reasoning Pro, and Sonar Deep Research each pull sources differently. The 2-3x citation-density gap between tiers changes what pages get cited — and how you should test.

2026-09-18T00:00:00Z https://geohandbook.io/articles/google-ai-structured-data/

Not all schema is equal for AI Overviews. Product+Offer+AggregateRating dominates commercial queries; FAQPage and Article schema dominate informational. Here's the JSON-LD that moves citation share, with real markup.

2026-09-18T00:00:00Z https://geohandbook.io/articles/google-ai-mode-optimization/

AI Mode passed one billion monthly users a year after debut, with queries doubling every quarter. It's a different surface from AI Overviews — and it rewards different content.

2026-09-18T00:00:00Z https://geohandbook.io/articles/digital-pr-for-geo/

Earned media drives 25% of all LLM citations across ChatGPT, Claude, Gemini, and Perplexity. Only 6% of GEO practitioners use it as a primary tactic. Here's the widest arbitrage opportunity in AI search.

2026-09-18T00:00:00Z https://geohandbook.io/articles/content-freshness-ai-search/

About half of Perplexity's citations resolve to content under 13 weeks old. Recently updated pages average 6 AI citations vs 3.6 for stale ones. Here's the refresh cadence that keeps you in the citation pool.

Before you buy a $499/month citation tracker, do the manual audit yourself. Here's the exact eight-step process, the eight gap types, and when the paid tools actually earn their keep.

2026-09-18T00:00:00Z https://geohandbook.io/articles/chatgpt-citation-signals/

Bing indexation is table stakes, not the finish line. ChatGPT decides citations across three separate stages, and each one filters out most candidate pages.
