PR earns coverage and reputation with reporters, analysts and audiences, while GEO, short for generative engine optimization, measures and improves whether AI answers name and cite a brand. PR is an input to GEO: Muck Rack's May 2026 study of more than 25 million links found that earned media made up 84 percent of AI citations. The two differ in owner, output and measure, and most brands need both.
Summary
- PR builds third-party coverage, and GEO checks whether that coverage and the brand's own pages show up in AI answers.
- Muck Rack reported that paid or advertorial content made up 0.3 percent of AI citations in May 2026.
- GEO adds work PR does not do: tracking prompts engine by engine and rewriting pages so facts can be quoted.
- A brand with weak coverage should start with PR, and a brand with strong coverage and weak pages should start with GEO.

What Is the Difference Between PR and GEO?
PR and GEO differ in what they aim to produce and how they are measured. PR aims to earn coverage and trust from people, and GEO aims to make a brand appear and be cited inside AI-written answers. The table sets the two side by side.
| PR | GEO |
|---|
| Goal | Earn coverage, quotes and trust from reporters, analysts and audiences | Get a brand named, and its pages cited, in answers from ChatGPT, Claude, Gemini, Perplexity and Google AI Overviews |
| Main output | Placements, interviews, announcements and crisis responses | Retrievable pages, consistent brand facts and a tracked set of prompts |
| Usual owner | Communications or an outside PR agency | Marketing, SEO or a communications team that has added the work |
| Usual measure | Coverage quality, reach and sentiment | Share of tracked AI answers that name the brand, and share that cite its pages |
| Typical failure | Coverage that never reaches the sources AI engines read | Well-built pages with no independent coverage behind them |
EPR's guide to generative engine optimization defines the discipline in full, and the GEO canon lists every GEO asset on the site. For how GEO differs from search optimization, see GEO vs SEO and AEO vs GEO vs SEO.
How Does PR Feed GEO?
PR feeds GEO because AI engines draw most of their cited sources from unpaid third-party pages, which is the material PR produces. Muck Rack's May 2026 edition of What Is AI Reading? reported that earned media made up 84 percent of citations across ChatGPT, Claude and Gemini in a sample of more than 25 million links, and that paid or advertorial content made up 0.3 percent.
Two details change how a PR team should read that figure. Muck Rack counts journalism, academic research, government sources, encyclopedic sites and third-party corporate content as earned media, so 84 percent does not mean 84 percent news stories. In its December 2025 edition, Muck Rack reported that journalism made up 20 to 30 percent of citations. Muck Rack also sells a tracking product, so its reports are vendor research, and EPR treats the percentages as a snapshot, not a fixed rule.
The same Muck Rack series reported only a 2 percent overlap between the journalists brands pitch most and the journalists AI systems cite most, and a fivefold rise in press release citations between July and December 2025. EPR's PR vs SEO guide covers these findings in detail, and its press release retrieval study found that 47 of 250 wire-distributed releases were cited by AI engines within 90 days.
What Does GEO Add That PR Does Not Cover?
GEO adds three tasks that a PR program does not normally include: tracking AI answers by engine, publishing pages written so facts can be quoted, and keeping brand facts consistent across sources.
- Tracking by engine matters because engines behave differently. In a 5WPR measurement of 2,034 fintech answers on September 14, 2026, Airwallex appeared in 24.1 percent of Perplexity answers and 0.7 percent of ChatGPT answers, as reported in EPR's fintech AI visibility findings.
- Quotable pages matter because an engine that cannot find a fact on a brand's own page takes it from an outside source, which the same fintech study showed with Forbes and CNBC.
- Consistent facts matter because an AI answer can only repeat what sources say, so a spokesperson, product name or price that differs between sources produces mixed answers.
PR teams can do all three, but they rarely do so by default, because the usual PR report counts placements, not answers. EPR's GEO for B2B SaaS and GEO for healthcare pages show how the work looks in two specific categories.
A brand should use an AI visibility tool when an in-house team can act on the data, and hire an agency when nobody owns the page changes and the coverage work. A tool records whether AI answers name the brand, and an agency changes what those answers can draw on.
Tool pricing follows the number of prompts tracked. eSEOspace's GEO cost guide reported Otterly.AI list prices on October 13, 2026 of $29 a month for 15 prompts and $489 a month for 400 prompts, and WebFX's GEO cost guide puts AI visibility tracking software at $50 to $1,000+ a month and agency GEO services at $1,500 to $50,000+ a month. EPR estimates mid-sized and larger agency programs at $10,000 to $50,000+ a month. These are provider price lists and Everything-PR estimates, not audited benchmarks.
A tool without an owner for the follow-up work produces reports and no change in AI answers. Budget internal time for reviewing the data, updating pages and re-measuring, and see EPR's PR firm cost guide for retainer ranges.
Should a Brand Buy PR, GEO or Both?
A brand should buy PR first when it has little independent coverage, GEO first when it has coverage but weak pages, and both when it competes in a category where buyers research in AI answers. The table maps common situations to a starting point. This is EPR's judgment, not a finding from a published study.
| Situation | Start with | Reason |
|---|
| Few articles or mentions from independent outlets | PR | Engines have little third-party material to cite, so pages alone will not carry the brand. |
| Strong coverage, but AI answers omit the brand or get facts wrong | GEO | The coverage exists, so the gap is in tracking, page clarity or inconsistent facts. |
| A launch or funding round in the next quarter | PR, with a GEO check on the launch pages | The announcement needs reporters, and the launch pages need to be quotable. |
| A crisis or negative story that ranks and gets summarized | PR, with GEO tracking | The response has to reach the sources answers draw from, and tracking shows whether it did. |
| A category where buyers compare vendors inside AI answers | Both | Coverage earns the mention, and quotable pages earn the citation. |
How Do You Measure PR and GEO Together?
You measure PR and GEO together by tracking one set of buyer questions across every AI engine and recording two results for each, whether the answer names the brand and whether it cites a page the brand earned or owns. EPR recommends the following steps.
- Write 25 to 50 questions that real buyers ask about the category.
- Run each on ChatGPT, Claude, Gemini and Perplexity, more than once, and record the dates.
- Log whether each answer names the brand, and list every domain it cites.
- Sort the cited domains by frequency, and give the top outlets to the PR team as targets.
- Re-run the set each quarter and compare each engine against the baseline.
Run each question more than once, because AI answers vary between runs and a single result is only a sample. EPR's PR and search guide gives the share calculation and a 90-day plan.
What Should You Ask an Agency That Sells Both?
You should ask an agency that sells both PR and GEO to show how it splits the work, what it reports and how it checks AI answers. Five questions separate firms that do both from firms that have renamed one.
- Which outlets did the agency earn coverage in last quarter, and did any of them appear in AI answers on the client's category?
- How many buyer questions does it track, on which engines, and how often?
- What does it change on the client's own pages, and who approves those changes?
- Does the monthly report show answers and citations, or placements only?
- Is GEO inside the retainer or priced separately?
