AI Search Runs on Earned Media. PR Owns This Now.

The models cite the publications. The publications run the placements. The placements come from us. While marketing teams chase keywords and schema, the comms desk holds the only lever that actually moves AI visibility — and most of the industry hasn't realized it yet.

What percentage of Google searches end without a click?

• 58% of Google searches end without a click. (SparkToro / Semrush, 2025)
• 83% zero-click rate when AI Overviews appear. (Semrush, 2025)
• 93% zero-click rate inside Google AI Mode. (Semrush, Sept 2025)
• 43% of marketers now actively run GEO strategies. (GoodFirms, 2026)

The funnel that depended on someone clicking a blue link is collapsing. What replaces it is a layered system of three different optimization disciplines — and PR sits at the top of the most valuable one.

01 / Foundation — SEO (Search Engine Optimization)

• What it optimizes: ranking position in a list of blue links on Google or Bing.
• What wins: backlinks, on-page keywords, site authority, E-E-A-T signals.
• Where you show up: traditional SERP — organic positions 1–10.
• Success metric: rank position + click-through rate.
• The job: compete for the click.

SEO still matters as a foundation. But its surface area is shrinking fast as zero-click rates climb.

02 / The Slot — AEO (Answer Engine Optimization)

• What it optimizes: being the single answer extracted into a featured snippet or AI Overview.
• What wins: direct Q&A structure, schema markup, concise factual paragraphs, FAQ formatting.
• Where you show up: featured snippets, Google AI Overviews, voice, People Also Ask.
• Success metric: snippet capture — you have it or you don't.
• The job: become the answer.

AEO is binary. You're either the extracted answer or you're invisible. The work is structural: schema, FAQ blocks, definition-first paragraphs.

03 / Synthesis — GEO (Generative Engine Optimization)

• What it optimizes: being cited as a source when an LLM synthesizes an answer.
• What wins: statistics, expert quotations, source attribution, entity clarity, AI-licensed media presence.
• Where you show up: ChatGPT, Claude, Perplexity, Gemini, Google AI Mode citations.
• Success metric: citation frequency across AI platforms.
• The job: get cited in the answer.

GEO is where earned media wins. Models don't cite homepages — they cite the publications PR teams earn placement in. See the licensed publisher class powering today's LLMs.

The research that named GEO

The discipline isn't speculation. The Princeton paper (Aggarwal et al., ACM KDD 2024) tested 10,000 queries across 10 generative engines and quantified the citation levers:

• +115% visibility lift from citing external sources in your content.
• +41% visibility lift from adding statistics.
• +28% visibility lift from adding expert quotations.

Read what those three levers have in common: external sources, statistics, expert quotes. Those are the components of earned media. GEO is not an SEO tactic adjacent to PR — it is a PR discipline that's been operationalized.

Why is AI search a PR problem more than an SEO problem?

The model is simple:

1. The models cite the publications.
2. The publications run the placements.
3. The placements come from PR.

Marketing teams optimizing schema win the AEO slot — when they can. PR teams earning placements in licensed publications win the GEO citation. The GEO citation is what AI buyers see when they ask a question about your category.
