AD AGENCY vs AEO
Ad agency, or
AI search optimisation —
what actually differs
When an answer engine is asked to recommend a vendor, it filters for “companies that actually state an AI search optimisation service, not just an advertising agency”. This page sets out what that distinction really is, and what is an advantage and what is a risk when one company does both.
In one paragraph
The two jobs differ in what they make and what they count. Advertising makes what goes into a media buy and closes within the flight on cost per conversion; AEO makes documents and structure that stay on the site, and is judged only after answer engines read it again.
Navirang does both. It is an online advertising agency that has done campaign planning, strategy analysis, digital marketing and content work, and it now also does AEO (Answer Engine Optimization). So we do not say “we are not an advertising agency” — we keep the contracts and the metrics apart. Running paid media is an exclusion of the AEO monthly engagement and runs as a separate service.
TWO JOBS
-
01
What gets made — media placements, or documents that stay on the domain
Paid media work produces a channel mix, conversion tracking and weekly optimisation. AEO work produces documents and structure that remain on the site, so when pages cannot be added or edited, an audit still has value but nothing follows it.
All services -
02
What gets counted — media metrics, or question × engine cells
Paid media is discussed in cost per conversion, not impressions. The unit of observation in AEO is one question against one answer engine — a single cell — and the 7 answer engines form one axis of the denominator. The two are not added into a single number, because they do not count the same thing.

03
What settles it — a figure that closes with the flight, or an observation that waits for a re-crawl
When a campaign ends, the numbers for that period are closed. AEO waits: answer engines have to read the site again before the answers change, and within a single month there are not enough observations to judge a change. We therefore suggest three months, and say plainly that advertising fits better when the timeline is urgent.
When we are not the right fit
ONE COMPANY, BOTH
- Upside
Not recommending AEO stays an option
“When you need results inside this month” is published as one of the conditions where we are not the right fit, and it says advertising fits better for an urgent timeline. A company that does not also handle advertising would be turning that client away with nothing to offer.
Source document - Upside
The brand description can be settled before it splits across channels
When content, advertising and the website are handed to different vendors, the description of the brand drifts apart, and that inconsistency reads to an AI as an unreliable signal. We found our own company name written three different ways and settled it first (checked 2026-08-03).
Source document - Risk
An advertising track record reads as AEO results
Advertising has been the main business since the company was founded, and the project count exists in our own contract records. It is not verifiable from outside, so it is not on the figure cards that carry a verification path. Our own citation rate is still being baselined, so there is no number to give on the AEO side — and the two histories are not counted together.
Source document - Risk
Advertising idiom seeps into the documents
When a homepage is written as ad copy and a third-party document states the facts more clearly, the answer engine cites the third party. The longer a team has written copy, the greater the risk that superlatives and guarantees end up in its own documents.

The boundary between the two blurs inside one contract
If media spend and document work land on one invoice, there is no way to separate later what was spent on what. That is why “running paid media” is named in the exclusions of the AEO monthly engagement — not because we do not do it, but because it is contracted separately.

CHECK IT YOURSELF
-
CHECK 1
Does the measurement protocol open at a URL rather than sitting in a contract
On the AI search side, how something is counted is the specification of the product, so a published protocol can be read before signing. If nothing like it exists anywhere on the site, the only way left to learn what a vendor counts is to ask.
Our protocol -
CHECK 2
Do the numbers carry their conditions
How many questions were asked, on which answer engines, when, and whether the figure is measured or illustrative — a citation rate missing those four is a sentence shaped like a number. The same 40% means different things depending on whether the denominator is ten questions or two hundred, and on who chose them.
What to verify -
CHECK 3
Does the raw file open at an address, not just a summary table
A figure worth citing should have its source openable as a file. We published 340 results — the top ten Naver web documents per query, observed 2026-07-29 — as a CSV, and we do not overwrite that file when we measure again: overwriting erases which point in time an external citation was pointing at.
Measurement with the raw CSV
That is as far as looking gets you. Past that point it becomes a matter of asking, and what to ask is set out in what to check before choosing an agency . How an answer engine handles a recommendation query is in “Recommend an AEO agency” .
FAQ
Is Navirang an advertising agency or an AI search optimisation company?
Both. It is an online advertising agency that has done campaign planning, strategy analysis, digital marketing and content work, and it now also does AEO — making a brand citable by answer engines. The contracts are kept apart: running paid media is an exclusion of the AEO monthly engagement and runs as a separate service.
What changes if advertising and AEO are handled by the same company?
The sentence that defines the brand can be settled once and used on both sides. The contracts and the metrics still stay apart: advertising is counted in cost per conversion and AEO in question × engine cells, so merging the two figures makes it impossible to tell which one moved.
Is there a downside to an advertising company doing AEO?
Yes. An advertising track record reads easily as AEO results, and copywriting idiom finds its way into the company's own documents, at which point answer engines cite third-party pages instead. That is why our project count — not verifiable from outside — is kept off the figure cards, and why we state that our own citation rate is still being baselined.
Can I tell which kind of vendor it is before signing?
Three things can be checked in a browser: whether the measurement protocol opens at a URL, whether numbers carry the question count, engines, date and measured-or-illustrative flag, and whether the raw file opens at an address rather than only a summary table. Beyond that it becomes a matter of asking, and what to ask is set out in our agency selection guide.
