Supplement Google Ads Case Study: 6.49 ROAS for SolBiome

Last updated: 11 November 2026. Results period: 17 July to 10 November 2026.

SolBiome, a Melbourne probiotic supplement brand selling through a Shopify store, handed its Google Ads account to Hustle Marketers on 17 July 2026. Over the next 117 days, Performance Max, Shopping and Search campaigns returned A$31.3k in tracked purchase value from A$4.82k in ad spend. This supplement Google Ads case study shows how the account was set up, where the return came from, and what supplement brands should check before they advertise.

Quick Answer: What did Google Ads deliver for SolBiome?

Google Ads returned a conversion value to cost ratio of 6.49 for SolBiome from 17 July to 10 November 2026. That is A$6.49 in tracked purchase value for every A$1 spent: A$31,300.59 on A$4,820.19 of spend, across 259 purchases and 2,340 clicks. The return came from a full Google Shopping setup: an optimised Merchant Center feed, free listings, product ratings, dynamic remarketing and Performance Max, Shopping and Search campaigns.

The Client: Who is SolBiome?

SolBiome is an Australian supplement brand that sells a daily probiotic, Multi+, direct to consumers through its own Shopify store. Its Clutch review lists a retail business in Melbourne with 1 to 10 employees, and its director, Emily Carlstrom, found Hustle Marketers on Upwork, where Ishant Sharma is Top Rated Plus.

Supplements are one of the harder ecommerce categories to advertise. Google treats health products as a restricted area, and Australian ads for listed medicines also sit under the TGA advertising rules. A small brand needs campaigns that sell without running into either set of rules.

The Challenge: What did SolBiome need from Google Ads?

SolBiome needed Google Ads and Shopping campaigns set up and then managed, without an in-house media buyer. In the director’s words on Clutch, the brand “needed help setting up our Google Ads and shopping campaigns and managing them.”

• A small daily budget. The whole account runs on A$65 a day, so every dollar has to go where it returns the most.
• One hero product. With a single core product, the campaigns cannot spread spend across a large catalogue. They have to reach different buyers with different reasons to buy the same product.
• A restricted category. Ad text, product data and landing pages all have to stay inside Google’s healthcare policies and Australia’s therapeutic goods advertising rules.

Our Strategy: How was the supplement account built?

The account was built around three jobs: give Google clean product data, reach buyers by the reason they are shopping, and measure only real purchases. Here is how each part works.

How are purchases tracked?

Purchases from the Shopify store are the account’s primary conversion goal, so Smart Bidding only optimises toward sales and their value. Google Analytics 4 was linked to Google Ads on 17 July 2026. For the setup steps, see our guide to Google Ads conversion tracking.

What was done in Google Merchant Center?

Shopping and Performance Max can only be as good as the product data behind them, so Merchant Center was set up and optimised before campaigns were scaled. These are the pieces SolBiome’s store now runs on:

• Feed optimisation. Product titles, descriptions and product data in the Shopify feed were rewritten to match how people search, while staying inside Google’s health claim rules. Our Google Merchant Center requirements guide covers the rules that matter most.
• Free listings. Products also show in Google’s unpaid product listings, which adds visibility at no ad cost. See our free listings setup guide.
• Product ratings. Merchant Center for solbiome.com was enabled for Google Product Ratings on 17 July 2026, so star ratings from the store’s reviews can show on Shopping ads. Our guides to seller ratings vs product ratings and syncing reviews to Merchant Center explain how it works.
• Dynamic remarketing. Shoppers who viewed products on the store can be shown those products again across Google, set up within Google’s rules for health-related advertising. Read more in our Google Ads remarketing guide.

How are the campaigns split?

The account runs three Performance Max campaigns, a Standard Shopping campaign and a Search campaign on a total budget of A$65 a day. Each campaign has one clear job, so budget can be moved to where it returns the most instead of being averaged out inside one large campaign.

• Performance Max by shopping reason. Separate asset groups for each reason people buy (gut, skin, mood and an all-in-one message) let Google match the message to the searcher.
• A test campaign for new themes. New keyword themes and messages are tried on a small budget before they move into the main campaign.
• Standard Shopping. A focused product listing campaign alongside Performance Max.
• Search. Search campaigns cover high-intent searches on Google.

How do the ads stay inside supplement advertising rules?

Google bans supplement ads that present a product as able to prevent, cure or treat a disease, and it bans supplements with active pharmaceutical or dangerous ingredients (Google Ads healthcare and medicines policy). In Australia, an ad for a listed medicine must not be inconsistent with the indications accepted for it on the Australian Register of Therapeutic Goods (Therapeutic Goods Advertising Code 2021). In practice, the aim for every headline, description and product title is a reason to buy, not a medical claim, and policy status is checked in every monthly review. Our healthcare PPC guide covers these rules in more depth.

What does monthly optimisation cover?

• Moving budget toward the campaigns with the best return, while watching the ones limited by budget.
• Reviewing search terms and asset performance for each asset group, and replacing weak headlines and images.
• Checking product and ad approvals, so policy issues are fixed before they cost impressions.
• Judging every campaign against the store’s break-even ROAS. Our break-even ROAS guide shows the calculation.

The Results: What did 117 days of Google Ads produce?

From 17 July to 10 November 2026, SolBiome’s Google Ads account recorded 259 purchases worth A$31,300.59 from A$4,820.19 of spend, a conversion value to cost ratio of 6.49. The average tracked purchase was worth about A$120.85, and the average cost per purchase was about A$18.61.

What We Learned: What does the data say about supplement ads?

• Fix the feed before buying clicks. For a one-product supplement brand, Shopping and Performance Max depend on clean, policy-safe product data. Merchant Center work came before scaling spend.
• Group buyers by why they buy. One product, several reasons to buy it. Separate asset groups for each reason let Google match the message to the searcher, and show which reasons sell.
• Test on a small budget first. New themes run in their own campaign on a small budget, so weaker ideas are found before they reach the main campaigns.
• Budget is the next constraint. The strongest Performance Max campaigns were limited by budget at the end of the period, so the next gain comes from funding them, not from rebuilding them.
• Policy work never stops. Google’s healthcare rules change; in June 2025, for example, Google removed the global ban on melatonin ads outside the US and Canada (Google Ads policy update). Ads and feeds are rechecked whenever products or rules change.

What should supplement brands check before running Google Ads in Australia?

Supplement brands should check three sets of rules before launch: Google’s healthcare policies, Google’s limits on health audiences, and, in Australia, the TGA advertising code. The table sets them side by side.

FAQs: Google Ads for Supplement Brands

How do you advertise supplements on Google Ads?

Advertise supplements on Google Ads with Performance Max or Shopping campaigns fed by a clean, optimised Merchant Center product feed, plus Search, and keep every ad and product description free of disease or drug claims. Google bans claims that a supplement prevents, cures or treats a disease (healthcare and medicines policy).

Can probiotics be advertised on Google Shopping?

Yes, probiotics can run on Google Shopping and Performance Max if the product contains no restricted ingredients and the feed and landing page make no false or misleading health claims. SolBiome’s account runs Shopping, Performance Max and free listings for a probiotic, with product ratings turned on.

What is a good ROAS for a supplement brand on Google Ads?

A good ROAS is one above your break-even ROAS, which depends on your margins, so there is no single number. SolBiome’s account returned 6.49 over 117 days, and the client describes a consistent 4 to 6 times return.

Do Australian supplement ads have to follow the TGA advertising code?

Yes. Ads for therapeutic goods in Australia, including listed complementary medicines, must follow the Therapeutic Goods Advertising Code, which requires claims to stay within the product’s accepted ARTG indications (TGA).

Can supplement brands use customer lists in Google Ads?

Often not. Google treats health as a sensitive interest category and does not allow Customer Match, your data segments or lookalikes for health-related personalised ads (Google policy). How your ads and pages are positioned decides whether this applies.
