ChatGPT Ads Now Connects to Shopify and HubSpot. Should You Move Budget?

ChatGPT now runs ads. That’s been true since early 2026. What changed on 16 September was something more specific: OpenAI added Shopify and HubSpot as the first native integrations into its ad platform. If you’re a Shopify merchant or you run your sales pipeline through HubSpot, you can now set up ChatGPT campaigns without ever logging into a separate ad manager.

The question for Australian small businesses isn’t whether this is interesting, it is. The question is whether it’s interesting enough to move budget away from Google and Meta. Short answer: probably not yet. Longer answer below.

What actually launched

OpenAI announced three things at once, and it’s worth separating them because they’re not all equally available.

Sponsored Agents, the headline feature, let users opt into a labeled conversation with a business’s AI agent after seeing an ad in ChatGPT. So a customer asks ChatGPT about finding a good accountant for their e-commerce store, sees your ad, taps it, and gets dropped into a separate, clearly-marked chat with your agent. The agent can answer questions, explain your services, and hand them a link to book when they’re ready. This is still a limited US-only test with selected advertisers. Most businesses can’t run one yet.

AI creative tools in Ads Manager, live now. You can use natural-language prompts in ChatGPT to build a campaign, generate copy suggestions from your landing page, and let the platform auto-translate ads into the user’s language. These tools are available to anyone with a ChatGPT Ads account.

Shopify and HubSpot integrations, live. This is the part that actually changes day-to-day workflow for small business owners. Shopify merchants connect the ChatGPT Ads app from the Shopify App Store, and your product catalog is automatically pulled in. HubSpot users can create campaigns, track performance, and follow up on leads without leaving HubSpot. OpenAI said international availability for the Shopify integration started 23 September.

Australia’s situation right now

Australian advertisers have been able to buy ChatGPT Ads through the self-serve Ads Manager since May 2026, this isn’t a fresh launch for us. The Shopify app rolling out internationally from 23 September means Australian Shopify merchants should now be able to access it, though the HubSpot integration status for non-US accounts is still unclear based on current reporting.

On pricing: OpenAI recommends an opening CPC bid of USD$3–5, which works out to roughly AUD$4.65–7.75 per click at current exchange rates. CPM (cost per thousand impressions) runs around AUD$38–70 in practice, with the platform maximum set at AUD$93. There’s no minimum spend, OpenAI dropped the original US$200,000 floor back in May.

Those numbers look reasonable until you hit the targeting constraint that barely gets discussed: outside the United States, geographic targeting is country-level only. Australian advertisers can target Australia. That’s it. No state, no metro, no suburb, no postcode.

If you’re a plumber in Adelaide or a physio in Brisbane, you’re paying for clicks from across the entire country. Most of those visitors can’t become your customers. This single limitation disqualifies ChatGPT Ads for the majority of Australian small businesses right now.

Who’s actually a good fit

The businesses where ChatGPT Ads currently make sense in Australia share a few things in common: they sell or service nationally, they have a clear offer that can be expressed in a short sentence, and they have product or service data that’s already clean.

National e-commerce on Shopify is the clearest match. If you’re already shipping to customers across Australia, country-level targeting isn’t a handicap, it’s fine. The Shopify integration means your catalog is already connected. The thing to check is whether your product descriptions were written for humans or for SEO keyword density, because conversational ad surfaces quote your copy differently than a search result snippet does.

Considered-purchase categories where customers genuinely research before buying, travel, home improvement, software, education, also fit well. These are the conversations already happening in ChatGPT, and an ad appearing alongside a real research conversation is a different context from an ad interrupting a Facebook scroll.

HubSpot users in B2B sales are a trickier case. The integration is convenient, but there’s a structural problem: ChatGPT ads only serve to users on the free and Go tiers. Anyone on Plus, Pro, Business or Enterprise sees nothing. The people most likely to be paying for a ChatGPT subscription are consultants, developers, and decision-makers, the exact buyers many B2B businesses want. If your target customer is a professional who uses AI heavily for work, the ad-eligible half of the audience might be the wrong half.

What the early numbers look like

The honest picture: thin data, with a couple of genuinely useful signals.

Two published advertiser tests found click-through rates of 0.65% and 1.30%, with almost no completed conversions between them. One test recorded 8,940 impressions, 58 clicks, and zero leads submitted. OpenAI has said it doesn’t yet have vertical performance benchmarks to share.

The counterweight is a finding from Criteo across 500 US retailers: traffic referred from large language models converted at about 1.5 times the rate of other referral channels. That’s consistent with what several agencies have noted anecdotally, AI-referred sessions are smaller in volume but the visitors arrive more informed. They’ve already done some comparison work before clicking.

So the early picture is high intent per click, low volume, costs above Meta but below LinkedIn, and no proven path to scale yet. That’s a normal profile for a six-month-old platform. It’s not a normal profile for a channel you fund from your primary budget.

Should you move budget from Google or Meta?

No, at least not meaningfully, and not yet.

Google Search still captures people at the moment they’re ready to act. Meta still reaches broad audiences cheaply for awareness and retargeting. ChatGPT Ads sits in a third category, call it conversational intent, where the user is mid-research, explaining their problem in natural language. That’s a real surface worth being present on. It’s not a replacement for the other two.

A reasonable starting point if you’re already spending on paid media: keep your existing budget where it’s performing, and carve out a capped test, say $2,000–3,000 AUD over six weeks, through the Shopify or HubSpot integration. Set a kill criterion before you start. If you don’t hit a minimum number of tracked conversions at a CPA you can live with, stop and reallocate. Decide this in advance, not after the platform has quietly become a permanent line item.

The businesses that will benefit most from the Shopify and HubSpot integrations aren’t necessarily those with the biggest budgets. They’re the ones with clean data. Accurate product descriptions, up-to-date pricing, a defined offer. The integration just removes the manual work of setting up a campaign, the quality of what you put in still determines what comes out.
