Do You Need a GEO Agency Alongside SEO?
Compare extending your SEO agency, adding a GEO specialist, or combining the work. Define ownership and AI visibility evidence before hiring.

Define the Gap Before Adding Another Agency
If you already work with an SEO agency, first ask whether your next problem is conventional search discovery, inaccurate product information, or visibility in AI-generated answers. A buyer asking ChatGPT or Perplexity for a shortlist may need evidence that differs from a visitor reading your own product page.
For this guide, GEO means generative engine optimization: improving the materials and evidence that can help a brand be discovered, described, cited, or recommended in AI answers. An agency using AI to write ordinary SEO content may be offering a different service. Ask both providers to define their scope.
This is Meridian's proposed procurement framework. It does not assume that adding a provider will increase AI recommendations.
SEO vs GEO vs AEO: define the work behind the label
Use the following working definitions when comparing proposals. AEO means answer engine optimization; suppliers may use it for direct answers, generative answers, or both. Ask which products and surfaces their proposal covers rather than assuming the acronym settles the scope.
Swipe horizontally to compare the complete scope.
| Label | Scope to clarify | Evidence to request |
|---|---|---|
| SEO | Search discovery, useful landing pages and relevant organic visits | Search queries and pages, technical findings, completed changes and business events |
| AEO | The particular answer surfaces the supplier intends to address | Named platforms, example answers and source links, with observation conditions |
| GEO | How generative answers describe, cite or recommend the business | Accurate business facts, supporting sources, observed gaps and a plan to review them |
These scopes can share the same page and people. For example, Google's guidance for AI features, checked September 29, 2026, says its existing SEO fundamentals apply to AI Overviews and AI Mode, with no additional technical requirements. That is guidance for Google's features; it does not establish how every other assistant selects sources.
The buying decision is therefore which work is missing and who can perform it. If a proposal uses “AEO” for the same research, pages and reporting another calls “GEO,” compare the deliverables directly before paying for two programs.
Compare Three Collaboration Options
| Option | When to evaluate it | What to verify |
|---|---|---|
| Extend the existing SEO agency's scope | The team can show a clear AI-search research and measurement process | A repeatable question set, evidence records, relevant deliverables, and staff capacity |
| Add a GEO specialist | The SEO program works, but the AI-search evidence or distribution work is missing | A single shared content queue, clear handoffs, and separate reporting definitions |
| Combine SEO and GEO with one partner | You are already reconsidering ownership or coordination | Migration of access and records, implementation responsibility, and the cost of changing providers |
Compare the work required before choosing an organizational model. Ask your current team to show an example first; an unfamiliar service label alone is not evidence of a capability gap.
Keep Website Ownership Clear
Two agencies should not independently edit the same page or publish competing articles for the same buyer question. Keep one owner for the website backlog and one approval route for product facts.
| Workstream | Responsibility to agree |
|---|---|
| Technical SEO and indexing | Who diagnoses, who implements, and who checks the live change |
| Buyer questions and page priorities | Who maintains the shared map and resolves overlapping briefs |
| AI answer research | Who records the prompt, platform, date, answer, and cited URLs |
| Content production | Who writes, checks product claims, publishes, and maintains each asset |
| Third-party evidence and distribution | Who supplies sources, checks attribution, and coordinates authorized participation |
| Reporting | Who separates search data, AI answer observations, referrals, and sales-confirmed outcomes |
Meridian's GEO service scope supports collaboration with an existing SEO agency or internal team. Its current six-month program requires client approvals, website publishing, technical implementation, and finished video assets. Confirm those dependencies before buying a recurring production schedule.
Check for overlapping charges before splitting the budget
Consider an illustrative situation: both an SEO agency and a GEO specialist propose rewriting the same product page because its integration limits are unclear. Assign one owner to the page, one product reviewer and one acceptance decision for the copy. The specialist may still contribute a separate review of observed AI answers, but that extra work should be named and scoped separately.
Compare each quoted item by affected URL or asset, required change, deliverable, reviewer and recurring responsibility. Two labels do not justify counting the same rewrite twice. Equally, separate research, editorial review and implementation can be legitimate work when each has a distinct output. Ask suppliers to show that division; do not assume every apparent overlap is a duplicate charge.
There is no fixed SEO/GEO budget split in this example. Fund the confirmed gap and the team's capacity to implement it. If the immediate concern is a missing citation or inaccurate recommendation, use the ChatGPT visibility troubleshooting guide to clarify the problem before expanding the engagement.
Ask for a Baseline You Can Inspect
A baseline should save the exact buyer questions, target market, platforms, collection dates, and answer evidence. Record the comparison conditions and any changes to the question set.
For each observation, distinguish:
- Mention: the brand is named.
- Citation: a source URL is cited; record which domain and page it belongs to.
- Recommendation: the answer positions the brand as an option for the stated need.
- Referral: a visit is attributed to an observable source in analytics.
- Qualified enquiry: a prospect states a relevant need and your team confirms fit.
These are different events. A cited article may not recommend your brand, and an AI referral does not automatically become a customer. Answer variation and changing retrieval sources make repeated, documented observations more useful than a single favorable screenshot.
Review the Evidence Gap, Then Choose the Deliverable
An illustrative review might identify a product fact missing from your website, a weak answer to a buyer objection, or too little independent information for someone comparing providers. The corresponding work could be a corrected product page, a substantive comparison, or an authorized customer story.
Ask the agency to connect each proposed deliverable to the observed gap. A monthly article quota alone does not explain why those articles are needed. An owned social post, a paid placement, and an independent editorial recommendation should also be labeled separately in the record.
See Meridian's GEO method and the sample evidence framework for the proposed record structure. These examples explain the work; they do not present client outcomes.
Start with an Agreed Review Gate
Before recurring production, agree the buyer questions, baseline, shared page map, evidence sources, and task owners. At the review, check whether the proposed work addresses gaps and whether the team can implement it.
If the product positioning is still changing or nobody owns publishing, resolve that dependency first. If the current SEO agency already performs the work with usable evidence, extending its scope may be enough. If a specialist fills a documented gap, agree what it owns and how its work will enter the existing process.
