Why your beautiful new website lost its rankings (a Melbourne case pattern)

Every month a Melbourne business owner asks us the same question in different words: should we fix the Google listing, or start on the AI stuff? The honest answer is that one of them will pay you back in three weeks and the other in six months, and which is which depends entirely on how your customers phrase their problem.
They answer different questions
A Google Business Profile competes for proximity queries. Someone types “emergency plumber Coburg” or opens Maps, and Google ranks the nearby options by relevance, distance and prominence. The listing is the product: your categories, service list, hours, photos, review count and rating decide whether you appear in the three-result map pack and whether anyone taps through.
Answer engine optimisation competes for consideration queries. Someone asks ChatGPT which accounting firms in Melbourne handle crypto, or asks Google a question and reads the AI Overview instead of the results. There is no map pack and no ten blue links — there is one synthesised answer citing between two and six sources. AEO is the work of becoming one of those sources.
So the first question is not which channel is better. It is which sentence your customer types. “Near me” and “open now” go to the map. “Best”, “how much”, “which one should I use”, “is X worth it” go to the answer engines.
The three-week test
Here is the split we use when a business has one budget and has to choose.
Fix the Google Business Profile first if: customers come to you because you are close; the job is urgent or low-consideration; you serve a suburb or a radius rather than a city; or your profile is visibly incomplete. Trades, clinics, restaurants, mechanics, gyms, childcare, massage, takeaway. A profile that is missing its secondary categories and has 11 reviews will usually gain calls within a fortnight of being tidied up, and it costs you time rather than money.
Start with AEO first if: the purchase involves research; the buyer compares three or four providers over days or weeks; the fee is in the thousands; or your customers are asking questions your website does not answer. Law, accounting, migration, cosmetic procedures, B2B services, software, anything where a person asks an assistant “who should I talk to about…” before they ever open Maps.
Most businesses are somewhere in the middle, which is where the sequencing matters. If you are unsure, look at your enquiries from the last twenty customers and count how many mentioned distance. If more than half did, the map wins the first round.
One more signal that settles the argument for a lot of businesses: check what happens when you search your own service term without a suburb attached. If the screen fills with a map pack and little else, your customers never scroll far enough to read anything you wrote, and content work will feel like shouting into a cupboard until the listing is right. If instead you get an AI Overview and a row of comparison articles from directories you have never heard of, the map is not where the decision is being made, and no amount of listing polish will put you in that answer.
Google Business Profile work feeds AEO anyway
The false part of the Google Business Profile vs AEO framing is that they are separate systems. They are not. When an AI assistant answers a local question, it usually reaches for structured local data and aggregated reviews — the same places your listing feeds. Ask ChatGPT for the best Vietnamese restaurant in Footscray and the names that come back are the ones with many recent reviews, consistent addresses and a web presence that confirms what the listing claims.
Which means a neglected profile quietly caps your AEO ceiling. Three concrete overlaps:
- Name, address and phone consistency. If your listing says Suite 4 and your website footer says Level 1, and your Facebook page says something else again, a model has no confident answer and will pick a competitor it can state cleanly.
- Review volume and recency. Models describe businesses using the language of their reviews. Twelve reviews from 2023 produce nothing to say. Eighty reviews mentioning “same-day” and “bilingual” produce a sentence that reads like a recommendation.
- Categories and service names. The exact phrasing in your listing’s service list often becomes the phrasing used about you elsewhere. Write it the way a customer would say it, not the way your industry body does.
So the practical order for almost everyone: two weeks of listing hygiene, then AEO as the ongoing programme. Not one instead of the other.
What each one actually costs you
The Google Business Profile side is mostly unpaid labour. Complete every field, add the secondary categories you legitimately qualify for, list services with real names and prices, upload photos monthly, answer the Q&A yourself before a stranger does, and build a review habit — one request per completed job, sent by SMS with the link, is worth more than any clever tactic. Budget a morning to set up and half an hour a week after that.
AEO costs money because it is content and code. In practice: pages that answer complete questions instead of listing services, comparison and pricing pages that state numbers, schema markup so machines can parse what the page claims, and third-party presence so your name appears somewhere other than your own site. We run that as an ongoing programme from $1,000 a month; a full site build with the structure already in place runs $1,588–$3,588 depending on scope. If you only want to know where you stand first, the $199 audit tells you which of the two conversations you should be having.
The distinction worth keeping: listing work is maintenance that stops paying the moment you stop, while AEO work compounds — a page that earns citations keeps earning them while you sleep, and keeps doing it in Google, ChatGPT and Perplexity at once. That is why we rarely recommend choosing. We recommend ordering.
Frequently asked questions
If I fix my Google Business Profile, do I still need AEO?
Yes, but not immediately. The profile wins queries where distance decides the outcome. It does nothing for a customer who asks an assistant “which Melbourne firm should I use for X” — that answer is assembled from web content and citations, not from Maps. Businesses with a considered, higher-fee service lose those customers silently, because there is no impression count for an answer you were left out of.
Does having a Google Business Profile help ChatGPT recommend me?
Indirectly, and more than people expect. Assistants lean on aggregated local data and review text when they answer local questions. A complete listing with a consistent address and a steady flow of recent reviews gives a model something specific to say about you. An incomplete listing with a handful of old reviews gives it nothing, so it names somebody else.
How long before either one shows results?
Profile work often shows movement in calls and direction requests inside two to four weeks, because the ranking inputs are the fields you just filled in. AEO is slower — typically six to twelve weeks before you see your name appearing in AI answers for your own service terms, and longer for competitive comparison queries. Anyone promising AI citations in a fortnight is guessing.
We have no physical address customers visit. Is a listing still worth it?
Set it up as a service-area business, with the suburbs you actually serve rather than all of Victoria. You will rank less strongly than a business with a genuine shopfront in the searcher’s suburb, which is exactly why service-area businesses should move to AEO sooner than retailers do. Their customers are more likely to be asking a question than opening a map.
Can I do the Google Business Profile work myself and pay for AEO?
That is the split we suggest most often. The listing rewards someone with direct knowledge of the business — you know your real services, your hours and which photos are current — and the review habit only works if it belongs to whoever finishes the job. AEO needs content and technical work most owners have no time for. Keep the first, outsource the second.
