Shopify SEO for Australian Supplements: Claims and Copy

Quick answer: If your supplements are therapeutic goods (listed medicines such as vitamin or herbal capsules), your product pages, collection pages, blog posts and customer reviews can all count as advertising under the Therapeutic Goods Administration’s (TGA) definition, so SEO copy has to follow its rules. Rank for what the product is (ingredient, form, dose, brand, where to buy) and use benefit wording only where it has the same meaning as an indication on the product’s Australian Register of Therapeutic Goods (ARTG) entry. If you cannot find a matching indication, do not target that benefit keyword on the page. Foods such as protein powders follow food rules instead, and this is general information, not legal advice.

Shopify’s own help centre tells merchants to work out the keywords their customers use and put them in page titles, meta descriptions, image alt text and body content. For a supplement store in Australia, that advice has a trap in it. Some of the searches your buyers type are really health claims, and when you put a health claim on a product page, you are the one making it.

This post is for Australian Shopify supplement brands and retailers who stock other people’s products. It does not cover sunscreen, skincare ingredient searches or United States rules.

One limit up front. Prism3 does not certify claims, give legal advice or sign off wording, and nothing here declares any sentence compliant. Your product’s sponsor, a regulatory affairs consultant or a lawyer decides that. Everything below was checked against the TGA, Food Standards Australia New Zealand (FSANZ), Google and Shopify pages named in the text, as at 31 October 2026.

First, work out what your product is

The rules depend on what the product legally is, not on how you describe it. The TGA says a product can be a food or a therapeutic good, but not both.

Three details from the primary sources catch founders out:

• Listed does not mean assessed. The TGA says listed medicines are not individually assessed before supply. The sponsor (the product owner) self-certifies that the product meets the requirements.
• Some sport supplements are declared medicines. The TGA’s guidance (updated 2 October 2024) says an oral sport supplement that makes a therapeutic claim about maintaining or improving performance in sports, exercise or recreational activity is declared a therapeutic good if it contains a restricted ingredient or is in the dosage form of a tablet, capsule or pill (the dosage-form test applies from 30 November 2023). You cannot advertise or supply such a product until it is on the ARTG.
• Therapeutic claims do not automatically turn a food into a medicine. The TGA says a product with an applicable food standard (unless the Declared Goods Order captures it) that makes therapeutic claims may be a non-compliant food, dealt with by the state or territory food regulator. FSANZ says health claims about food must rest on food-health relationships substantiated under Standard 1.2.7.

This post concentrates on listed medicines. If you are unsure which group a product is in, use the TGA’s classification tools or ask an adviser before writing any SEO copy.

Your supplement pages are probably advertising

The TGA’s guidance on determining whether content is advertising (updated 7 April 2026) says to advertise includes any statement, picture or design intended, directly or indirectly, to promote the use or supply of the goods, judged on whether the content looks, on its face, designed to promote them. It covers websites, emails, blogs, social posts (including user-generated content), reviews and testimonials.

A product page is the textbook case. The TGA’s worked example is a pharmacy website listing complementary medicines with names, accepted indications and advisory statements. It is an advertisement whether or not it has a buy button.

Retailers carry the responsibility. A person who advertises, or causes the advertising of, therapeutic goods can commit an offence or be liable for a civil penalty if the advertisement does not comply. The TGA names retailers among those who can advertise, and says online retailers are responsible for what they publish even if they copied it from packaging or another website. Pasting your supplier’s description into Shopify does not remove your responsibility for it.

Context counts. The TGA lists features that look promotional: a call to action, price and availability, offers and discounts, emotive adjectives such as “life changing”, superlatives such as “the best”, and favourable comparisons. A page with prices, an add-to-cart button and enthusiastic copy ticks most of them.

Content marketing is the grey area. The TGA’s non-promotional example is a peer-reviewed journal article on omega-3 supplementation with no reference to commercial availability. For medical devices, it says articles on a site that sells the devices would likely form part of the advertising, even without naming products. In my reading, an ingredient guide on a store that sells the ingredient sits in the same position. That is my reading, not a TGA ruling on your page.

The rule that shapes your keyword list: match the ARTG indications

The TGA’s general requirements page (updated 11 March 2025) says advertisements must be accurate, balanced, not misleading, contain only substantiated claims, and be consistent with the product’s ARTG entry. The ARTG summary lists the indications allowed for the product, and advertising must not be inconsistent with them. The TGA’s legal framework page adds that it is an offence to advertise therapeutic goods for an indication or purpose that is not in the ARTG entry.

For listed medicines, the TGA’s permitted indications guidance (published 1 March 2018) says indications must come from a pre-approved list. Each has a therapeutic action and a therapeutic target, and some carry qualifiers such as “mild”.

You do not have to copy an indication word for word. The wording in advertising must have the same meaning, which the TGA defines as an equivalent therapeutic action and target. You can change the order and swap action words that mean the same thing. You cannot give the indication a different, broader or more specific target, change a qualifier the ARTG entry carries, or stretch it to imply treatment of a serious disease or the prevention or cure of any disease.

The TGA’s own example (the regulator’s illustration, not a claim about any product):

The second row is the SEO lesson. A keyword like “[ingredient] for [specific benefit]” can be more specific than the indication on the ARTG entry. The TGA says indications can be specific (naming a non-serious condition) or non-specific (such as general health maintenance), so check each entry rather than assume. Search demand does not license a claim.

Two more points from the same guidance:

• Numbers and timeframes are claims. The TGA gives “Results in 2 weeks” and “improves X by 10%” as claims about effectiveness that are not indications. You must hold evidence, and they must still comply with the Code.
• Describing what an ingredient does can imply a therapeutic use. The TGA’s example is a statement that calcium is a natural component of bone. Where the message suggests a health benefit, an indication of similar intent must be in the ARTG entry.

Build a claims map before you touch the keyword list

1. Get the ARTG entry for every product. The TGA’s ARTG page lets you search by name, ID or sponsor. Retailers can ask the supplier for the ARTG number. Copy each product’s indications and qualifiers into a spreadsheet. If a product makes therapeutic claims and you cannot find an entry, find out why before writing copy: it may be a food, or an unlisted product.

2. Pull your real query list from Search Console, a keyword tool and on-site search, then sort it.

Low risk is not a sign-off: these pages are still advertising, so every statement on them must be accurate and substantiated.

3. Run each benefit query through three questions.

1. Does this product’s ARTG entry hold an indication with the same action and target as my sentence?
2. Does my sentence keep every qualifier that entry carries?
3. Does it avoid naming a serious disease or implying treatment, prevention or cure?

Three yeses means the keyword can go into the plan, subject to sign-off by whoever clears your claims. Anything else, leave it out. Leaving a keyword out costs some search demand. Publishing the wrong claim can cost far more: the TGA’s sport supplement guidance says breaches of TGA laws can bring heavy fines, civil or criminal court action and jail time. The TGA says listed medicines can only make low-level claims, so in my judgement benefit keywords will often be the smallest part of a supplement store’s plan.

4. Give each approved query one page. Product queries go to product pages (see the product page SEO checklist), ingredient and form queries to collections (see Shopify collection page SEO).

5. Keep a claims log: the sentence, the product, the ARTG indication it maps to, who approved it and when.

Where claims hide in a Shopify store

An audit that only reads the product description misses most of the text. Shopify’s product CSV documentation lists the fields: Title, URL handle, Description, Type, Tags, SEO title, SEO description and image alt text, plus product metafields once defined. Add collection text, blog posts, review widgets and banners.

• The SEO fields fall back to the product fields. If the SEO description column is blank, Shopify uses the product Description, and a blank SEO title falls back to the product Title. An unreviewed claim in the body copy can end up in your search snippet.
• Tight length limits tempt people to cram. Shopify’s help centre says a page title can be up to 70 characters (60 avoids shortening) and recommends around 160 for a meta description, in natural phrases rather than keyword lists.
• The URL handle follows the title by default, so a benefit claim in a title is also in the address. If you change a live handle, Shopify’s help centre says you can create a URL redirect so the old address still works.
• Alt text, tags and metafields are text too. Shopify describes tags as keywords that help customers find a product. Any of them can carry a claim.

Names count. The TGA says businesses should consider whether a product, business or service name promotes the use or supply of therapeutic goods, and gives a Tribunal finding that a medicine’s name advertised weight loss because the name referred to that use. Its permitted indications guidance adds that a name implying a therapeutic indication means that indication must be in the ARTG entry. Product titles, collection names and handles are names, so run the three questions on any that describe what a product does for the body.

Reviews, testimonials and user comments

Review apps are an SEO asset (see Shopify product reviews and star ratings) and, for supplements, advertising. The TGA’s testimonials guidance (updated 11 March 2025) says:

• Reviews and user comments are testimonials, and one on or linked to your content becomes part of your advertising. You are responsible for it even if you did not write it or do not agree with it.
• A testimonial must not be inconsistent with the ARTG indications or refer to health benefits that are not typical when the product is used as directed.
• Testimonials given for payment or any valuable consideration cannot be used. The TGA’s examples include free product and discounts on product, and it says this covers brand ambassadors and influencers. A sale or discount offered to all consumers equally, and not tied to leaving a testimonial, is not valuable consideration.
• Testimonials from a current or former health practitioner, or someone who presents themselves as qualified to diagnose, treat or prevent disease, cannot be used.

So avoid “review for a discount” programs without advice, and moderate reviews so outcome and condition claims do not sit unchecked on your page. The TGA’s social media page (updated 12 November 2025) says the same about your own social pages: owners are responsible for third-party comments.

Blog posts and ingredient guides

Ingredient content can still earn its place. A workable pattern:

• Product pages are advertising. Write them to the ARTG indications and the label.
• Ingredient and format guides that link to your products: treat as advertising too. Keep them to what the ingredient is, where it comes from, the forms it comes in, how to read a supplement label, and serving and storage facts on your label. Leave out outcome claims.

If you quote research, the Code treats it as a scientific or clinical representation with its own citation rules (the TGA’s general requirements guidance, updated 3 October 2024). In my reading, that is a reason to keep outcome studies off a store page unless an adviser has cleared them.

AI tools quote page text, and a quoted sentence loses its context. Write each sentence so you would be comfortable seeing it repeated alone, and keep structured data to what the page says (see schema markup and AI citations).

Words to audit for

Search your exported text for these and review every hit. Sources are TGA pages read on 31 October 2026.

The Code also bars ads that discourage seeking medical attention or suggest a product is better than treatment prescribed by a health professional, so check testimonials and FAQ answers too.

A claims audit you can run in an afternoon

1. Export products as a CSV, and copy out collection and blog text.
2. Build a word list from the table above plus every benefit and condition word in your keyword research, then flag every text cell that contains one.
3. Test each hit against the ARTG entry with the three questions: keep, reword to the same meaning, or remove.
4. Fix source fields first: description before SEO description, title before SEO title, because of the fallback.
5. Check the live output: the title tag, meta description and structured data your theme or apps generate.
6. Fix reviews and widgets, and set a moderation rule.
7. Log it and diarise a review. The TGA published an update to listed medicine ingredients on 16 October 2026, so the requirements behind these products do change.

Make edits in the admin, or by a bulk import you have tested on a few products first. Shopify’s CSV documentation warns that when you overwrite products with matching handles, a blank non-required cell overwrites the existing value.

What SEO can and cannot do here

Staying inside your ARTG indications narrows your benefit keywords, but plenty stays open: product, ingredient, form, brand and label-fact queries, collection structure that matches how people shop, clean titles and descriptions, and fast, crawlable pages. Nobody can promise where those will rank, and I will not.

Prism3’s Shopify SEO work for a supplement store is a keyword map filtered through your claims map, on-page work on titles, headings and descriptions, collection structure and technical checks, tied to revenue. We do not certify claims, write legal wording, or run ads or email. More guides are in the Shopify SEO and CRO resource hub, and products for babies or children are covered in Shopify SEO for Australian baby and kids brands.

Get qualified help if you are unsure whether a product is a food or a medicine, want to mention a named disease, or hold supplier claims with no ARTG entry behind them. The TGA lets you make an advertising enquiry and publishes the checklist “Is your advertising for therapeutic goods compliant?”.

Key takeaways

• A product is a food or a therapeutic good, not both. Settle which before you write copy.
• The TGA treats websites, blogs, reviews and product names as potential advertising, and retailers answer for what they publish.
• Benefit keywords must have the same meaning as an indication on the ARTG entry. Search demand does not change that: no matching indication, no keyword on that page.
• Build a claims map and log, and audit every text field, not just the description.
• Reviews are testimonials. Do not run incentivised review programs without advice.
• The lowest-risk ground is product, ingredient, form, brand and label-fact queries, plus good collection structure. This is general information, not legal advice.

FAQs

Can I target health benefit keywords on a Shopify supplement store in Australia?

Only where the wording has the same meaning as an indication on the product’s ARTG entry and you can substantiate it. The TGA says advertising for an indication not in the entry is an offence, and a benefit phrase with a narrower target than the entry has a different meaning. This is general information, not legal advice.

Do my blog posts count as advertising?

They can. The TGA assesses content case by case, looking at context, links and promotional features. Treat ingredient guides that link to your products as advertising.

Can I say my supplement is “TGA approved”?

No. The TGA’s legal framework page says advertising must not suggest approval or endorsement by a government authority, and allows a reference to the Act only in a statement of the registration or listing number. Its sport supplement guidance says an ARTG entry does not make a product “TGA approved” or “certified”.

Can I offer a discount if customers leave a review?

Be careful. The TGA says testimonials given for valuable consideration cannot be used, and its examples include discounts and free product. A discount offered to everyone equally, and not tied to a testimonial, is not valuable consideration. Get advice first.

Are protein powders covered by the same rules?

Not necessarily. The TGA lists protein powders, bars and energy drinks as products generally considered foods, which fall under the Food Standards Code. Declared sport supplements are different, so check which regime your product sits under.
