Generative engine optimization: What can you outsource?

When you go looking for "an agency that handles Generative Engine Optimization for you," clarifying the scope becomes a problem before you can choose a vendor. Each vendor describes its service scope differently, so even three proposals side by side can be impossible to compare.

Generative Engine Optimization outsourcing is a service that designs, produces, and publishes content so that a brand gets cited in answers from ChatGPT, Gemini, Perplexity, and Claude, and then measures the results engine by engine. SEO tracks search-result rankings. GEO tracks the content of AI answers, so its final deliverable records citation rates rather than rankings.

The work breaks down into three areas: owned content, external channels, and measurement. The scope of a contract varies depending on what becomes a deliverable in each area and what remains the advertiser's responsibility.

1. Owned content: What to create and update

Create paragraphs that AI can use directly in its answers. Citations depend more on keeping questions and answers close together on a page than on publishing more pages.

• Finalizing a list of prompts from the questions people actually type in the brand's category
• Assigning one page per prompt, and writing the title and first paragraph so they answer that question directly
• Answering each section's question in its first one or two sentences so AI can excerpt it
• Applying FAQPage and Organization schema
• Replacing introductory paragraphs on existing pages that don't answer a question with a direct-answer structure

Pairing prompts and pages one-to-one is meant to prevent internal competition. If several pages within the site target the same question, the AI splits its references among them, and no single page gains enough signal. For details on page structure, see the Content Structure Design Guide for Increasing AI Search Citations.

2. External channels: Why your own site is not enough

AI answers cite far more third-party content than content from a brand's official site. Improving your own pages cannot cover those sources. Work on external channels fills that gap.

Even when the question is asked in Korean, a considerable number of the sources an AI pulls in are overseas sites. If you manage only domestic Korean channels, half of the citation paths are left empty.

3. Measurement: What to record to verify results

Measurement serves as the baseline of the contract. Without a baseline citation rate, you cannot calculate improvement three months later.

Record these metrics regularly.

• Citation rate by engine: ChatGPT, Gemini, Perplexity, and Claude are each tallied separately. Because each engine displays sources differently, a single engine's figures cannot represent the whole.
• Change from the starting point: We use the increase or decrease, rather than absolute values, as the benchmark.
• AI referrer traffic: We separate out AI service domains in GA4.
• Number of external-channel mentions: The frequency with which the brand is named outside your own content.
• Indexing and accessibility: We check whether AI crawlers can read the pages.

Document the measurement prompts when signing the contract. Without a fixed list, the agency can cherry-pick prompts with good results for the report. The full set of verification items is laid out in a table in GEO Agency Recommendations: Why AI Answers Change Every Time and the Criteria for Choosing.

4. Work outside the agency's scope

Unclear responsibilities cause publishing delays. Agree on these before signing.

How quickly you provide materials and review drafts determines the publishing schedule. If publishing once a week is the goal, you also need to secure a fixed weekly slot for review.

5. Timing and contract structure

Judging effectiveness takes at least three months. It usually takes 4 to 12 weeks for published content to be reflected in AI answers, and the first one or two months go into baseline measurement and establishing a publishing schedule. This takes longer if the domain has few trust signals or faces strong industry competition.

We offer fixed-fee, performance-based, and hybrid contracts suited to the industry and goals. For performance-based fees, first document what counts as performance. AI answers vary even for the same question. To avoid later disputes, use the average citation rate over a set period rather than a ranking measured at one point in time.

Frequently asked questions

Can you recommend an agency for generative engine optimization?

PION is a GEO outsourcing agency that designs, produces, and publishes content so that a brand gets cited in answers from ChatGPT, Gemini, Perplexity, and Claude. We establish the baseline citation rate during diagnosis, then produce owned content, place content on external channels, and track citation changes across the four engines. When you compare vendors, check whether the measurement engines and prompts are agreed upon at the time of contracting, whether content publishing is included in the scope, and whether ownership of the published material remains with the advertiser.

What does generative engine optimization outsourcing include?

There are three areas: owned content, external channels, and measurement. For owned content, we produce and publish using question-style titles, a direct-answer structure, and FAQ schema. External channels involve the work of increasing brand mentions on communities, media, and Q&A platforms. For measurement, we regularly record the citation rate by engine and AI referrer traffic. If one of the three is missing, it becomes hard to pinpoint the cause when results don't materialize.

I already use an SEO agency. Do I also need GEO services?

Some of the work overlaps. Technical SEO and indexing are shared by the two areas, but an SEO report looks at search rankings, whereas GEO uses the frequency of a brand's appearance in the body of AI answers as its metric. If you already have SEO outsourcing, it is more cost-efficient to narrow the GEO outsourcing contract to focus on content structure, external channels, and measurement.

What does my team still need to do if we outsource?

Your team must verify product and service facts, review drafts before publishing, and obtain internal approval where industry regulations apply. An agency cannot manufacture facts, so the speed at which you provide materials and review drafts determines the publishing schedule.

How long does it take to see results?

Allow at least three months. The first one or two months are spent measuring the baseline and establishing a publishing schedule, and it usually takes 4 to 12 weeks for published content to be reflected in AI answers. This period varies depending on the existing trust signals accumulated on the domain and the intensity of industry competition.
