How ChatGPT picks agencies in Adelaide

We asked ChatGPT with web search "best digital marketing agencies in Adelaide" on 24 September 2026. It named 10 agencies. These are the websites it cited for them, with the number of times each was cited.

Websites ChatGPT cited, with citation counts
Website ChatGPT citedCitations
ppc4.com4
conquerradigital.com.au2
advantageppc.com.au1
digitalagencynetwork.com1
goodfirms.co1
marketingsweet.com.au1

Most of those citations went to directories and list pages such as ppc4.com, digitalagencynetwork.com and goodfirms.co, not to the agencies' own websites. AI answers lean on third-party pages to decide who to recommend.

Is this your agency?

Correct your details, add an office, or get your clients onto the Starworks directory pages that AI answers read. Starworks works with agencies that sell AI search work, and you keep the client relationship.

Not listed? We add an agency once its own website describes AI search work. Use the claim link and we will check your site.

How this list is made

On 20 October 2026 we read the websites of 9,688 Australian marketing, SEO and web agencies.

  • An agency is listed only when its own website describes AI search work in a full sentence, which we quote on its card with the page it came from. A keyword in a menu is not enough, and neither is an agency that only uses AI to write copy.
  • Each office is placed by the postcode on its Google Business Profile, not by the area it says it serves.
  • The order is the depth of AI search work described on the site first, then Google rating weighted by the number of reviews, so five stars from two reviews does not outrank 4.9 from two hundred.
  • Google ratings are shown as Google reports them. We do not collect reviews of agencies ourselves.
  • A city gets its own page once at least four agencies there qualify. Agencies elsewhere are listed on the Australia page.

Questions about AI SEO agencies in Adelaide

Which agencies in Adelaide offer AI SEO or GEO?

16 Adelaide agencies describe AI search work on their own websites as of 20 October 2026. The first listed are Online Path Digital Marketing, Adelaide SEO Marketing and Outsource SEO Australia. Each card quotes the sentence from the agency's site that qualified it.

What is GEO (generative engine optimisation)?

GEO is the work of getting a business found, described accurately and recommended in AI answers such as ChatGPT, Google AI Overviews, Gemini and Perplexity. It overlaps with SEO, but AI answers lean heavily on third-party pages such as directories, review sites and lists, not only on a business's own website.

How do I choose an AI SEO agency in Adelaide?

Ask for examples where a client is now named in ChatGPT or Google AI Overviews, and what they changed to get there. Ask which third-party sources they work on, because AI answers cite those heavily. Ask how they report results, since AI answers change from week to week and no one can promise a placement.

Can an agency pay to be listed or ranked higher here?

No. Listing and order come only from the agency's own website and its Google Business Profile, using the method on this page. An agency can correct its details or ask to be removed.

Where does ChatGPT get its list of Adelaide agencies?

When we asked ChatGPT with web search "best digital marketing agencies in Adelaide" on 24 September 2026, it named 10 agencies, and Purple Giraffe is on this page.

AI answers lean on third-party pages to decide who to recommend.
