How LLMO works

LLMO stands for large language model optimisation. Where answer engine work targets a live lookup — the model searches, finds your page, quotes it — LLMO targets the other source a model answers from: what it already holds about you from training, and what everyone except you has written about your business.

That distinction sets the whole approach. You cannot edit a model’s weights, file a correction or push an update. What you can change is the material the next model reads: your own site, but far more importantly the places where other people describe you — directories, publications, forums, supplier and partner pages, reviews, interviews. Consistency across those is the lever, and repetition over time is the mechanism.

Why LLMO matters

Because a model asked to recommend someone in your category will name whoever it can describe with confidence. If the web says little about you, or says contradictory things, you are a risky name for it to offer, and the enquiry goes to a business it knows better. That is a quiet loss: nothing in your reports records the times you were not mentioned.

It matters more for businesses selling across borders. A consultancy in Kathmandu working with clients in Australia or the UK is judged by a model on what the wider web can confirm, not on a local reputation that was never written down anywhere. Getting that reputation into public writing is most of the work.

Where LLMO goes wrong

The first mistake is expecting speed. Anything resting on training data moves on the schedule of the next model, not yours, so results are slow, uneven between systems and impossible to attribute cleanly. Anyone promising a quick change in what a model says about you is describing something they do not control.

The second is trying to game recall with volume: mass-published pages, spun descriptions, paid mentions on sites nobody reads. That output is interchangeable, and interchangeable text is precisely what a model has no reason to remember. The third is neglecting the corrections that are genuinely available — an out-of-date profile, a wrong address, an old service list still sitting on a directory nobody has looked at in years.

What to do about it

Begin with a record. Ask several models the questions a prospect would ask, in the markets you sell to, and write down exactly what each one says about you, including what it gets wrong and who it names instead. Without that baseline you will never know later whether anything moved.

Then fix sources rather than symptoms. Update every profile and listing so the facts agree, get accurate descriptions of your work published where humans genuinely read them, and give the web something specific to repeat — a method, a constraint, a distinct focus — instead of adjectives. The faster-moving, page-level side of this is answer engine optimisation, and the combined discipline is what the site groups under AI search optimisation.

Do and do not

Do

  • Correct wrong descriptions of you at their source
  • Earn mentions on sites models are likely to read
  • Record what each model says about you today

Do not

  • Expect a page edit to change model memory
  • Believe a vendor selling model recall guarantees
  • Publish self-praise instead of checkable specifics

Questions people ask about this

Can I make ChatGPT recommend my business?

Not directly, and nobody can sell you that. A model names businesses it can describe confidently, which comes from how widely and consistently it has seen you described. You influence that by fixing your profiles, earning accurate coverage in places people actually read, and being specific about what you do. It is slow, indirect work.

How is LLMO different from AEO?

AEO concerns a live lookup: the engine searches, retrieves a passage from your page and quotes it, so page structure and clarity decide the outcome. LLMO concerns what a model already holds, absorbed from training and from what others wrote about you. One responds to editing this week; the other responds to reputation built over years.

What if a model says something wrong about my business?

You cannot file a correction with the model itself. Find where the wrong information lives — an old profile, a stale directory entry, an outdated article, a leftover page of your own — and correct it at source, then make the right version easy to find and repeat. Recheck periodically, since change only shows once systems refresh what they read.
