Best ecommerce SEO agencies: my Australian shortlist of 8 (2026)

The best ecommerce SEO agency for an Australian store shows organic revenue from stores like yours and knows the rules your product pages live under. It also tells you the price. For a store that wants new collection and product pages shipped every week on a site it owns, my pick is Searchmaxxed. I'm Brenden House and I run Searchmaxxed. Yes, I put it first. This is my own selection, not an independent award, a survey or a measured ranking of how well any agency delivers for its clients.

The other seven worth calling are Kia Ora Digital, StudioHawk, Impressive, Megantic, Optimising, Spicy Web and Online Marketing Gurus. I read every agency's own ecommerce or Shopify SEO page on 26 October 2026, and each entry uses only what that agency publishes.

Which ecommerce SEO agencies made my shortlist?

Eight agencies made my 2026 shortlist. Every one of them works on Shopify, and most also name WooCommerce, BigCommerce or Magento.

How did I choose them?

I judged every agency on the same five things, using only what it publishes on its own website about its ecommerce work:

• Ecommerce proof they publish: named store case studies with organic revenue, orders or transactions, each quoted as that agency's own claim about its own client work. Traffic alone counts for less.
• Store-rule knowledge: whether the page shows it understands product structured data, Merchant Center and Google Shopping, and Australian consumer law on prices and reviews.
• Platform depth: named work on Shopify, Shopify Plus, BigCommerce, WooCommerce or Magento, including migrations.
• What they ship versus report: pages, templates and fixes that go live on the store count for more than a dashboard or a monthly report of activity.
• AI search capability: a published offer for Google's AI Overviews, ChatGPT, Gemini or Perplexity.

I started from the agencies Google showed on 26 October 2026 for "best ecommerce seo services", "ecommerce seo agency australia" and "shopify seo agency australia". Then I read each agency's own pages that same day, quoting only what each one says about its own ecommerce work. This is my selection, and I run the agency in first place. It can't measure how clients feel.

Why store rules? Because an online store sells under price, review and product data rules that a plumber or a law firm never meets. Google says product markup lets shoppers "see price, availability, review ratings, shipping information, and more right in search results" (Google Search Central). The ACCC is just as plain. It says businesses "must display a total price that includes taxes, duties and all unavoidable or pre-selected extra fees" (ACCC). It also says it's against the law for a business to "create fake or misleading reviews" or "arrange for others to create" them (ACCC). An agency that rewrites your product templates and runs your review requests works inside those rules every week.

1. Searchmaxxed: best for stores that want pages shipped every week on a site they own

Searchmaxxed is an SEO, AI SEO, GEO and AEO agency that builds collection pages, product pages, product schema and filter rules for online stores. It suits a store owner who wants the work live every week, not described in a monthly report. You own the site and the data.

• Where they are: Clients across Australia and beyond. You deal with the people doing the work, with no account managers.
• What they sell: Technical SEO, collection and product pages, product schema, faceted URL rules, internal links, link building and AI answer work on Shopify, BigCommerce, WooCommerce or Magento. Our ecommerce SEO page has the detail. The Managed Search Loop explains how your own Search Console and GA4 data decides which page or fix we build first.
• Proof they publish: Before Searchmaxxed, I built Radiant Roof Repairs from zero to more than A$1 million a year in revenue using SEO as the only marketing channel. That's a roofing business, not a store. Searchmaxxed's work has generated more than A$10 million in revenue through search for its clients.
• Pricing: Let's talk pricing.
• AI search: AEO and GEO come inside every managed package, and the Local Search, Growth System and Agentic Search Engineering packages include AI answer or visibility tracking.
• Store rules: Our ecommerce page covers Product schema that matches the visible price and stock, Merchant Center details and the ACCC's total-price rule.
• Ask them: Open my Search Console and show me the three collection or product pages you'd build or fix first.

2. Kia Ora Digital: best for growing brands that want revenue case studies

Kia Ora Digital suits a growing Shopify or DTC brand that wants case studies that show organic revenue and orders as well as traffic. Its ecommerce page carries one of the longest lists of named store results I read, and most of them quote organic revenue.

• Where they are: Its page takes enquiries on Australian and New Zealand numbers and shows "300+ Clients" and "5+ Global Awards".
• What they sell: Ecommerce SEO in four steps: an audit and growth plan, then strategy, then execution, then reporting "against your KPIs in plain English".
• Proof they publish: Sheila The Label shows "+318% Organic Revenue" and "+88% Organic Sessions", and Springrates shows "+151% Organic Revenue" and "+156% Organic Orders". 99 Bikes shows "29% Organic Revenue" as well.
• Pricing: Not published. The free growth plan comes with "No lock-in contracts, no obligation."
• AI search: The growth plan shows "how your store ranks in Google and ChatGPT".
• Store rules: The ecommerce page I read doesn't cover product schema, Merchant Center or the ACCC's rules on prices and reviews for online stores. Ask.
• Ask them: Over what period did Sheila The Label's revenue growth happen, and from what starting point?

3. StudioHawk: best for large retailers that want a big specialist team

StudioHawk suits an established retailer that wants a large SEO-only team with a deep bench of retail case studies to check against its own category. It publishes its own research, too.

• Where they are: Its SEO services page title reads "SEO Agency Melbourne", and its client logos include Officeworks, Petstock and Ryobi.
• What they sell: Technical SEO for large catalogues, product and category pages, Product schema, migrations and AI search, with a separate Shopify SEO page for Shopify stores.
• Proof they publish: Koala Living shows "535% Growth in organic revenue", plus 524% more transactions and 140% more organic traffic, alongside a site migration. Officeworks shows "60% Increase in organic traffic" and Clarks "101% Increase in organic revenue". It claims an "average 300% ROI".
• Pricing: Not published. Its enquiry form asks for a monthly budget, in brackets from "Below $3000" to "$15,000+", and it offers "No long-term, lock-in contracts".
• AI search: AI SEO for "AI Overviews, chatbots and answer engines", backed by a report for which it "studied 100 Australian eCommerce brands over 21 months". The report is called Chosen, Not Clicked.
• Store rules: Product schema "that helps you stand out in both search results and AI answers".
• Ask them: What did your 21-month study find for stores my size, and what would you change first because of it?

4. Impressive: best for big brands that also run Google Shopping

Impressive suits a large brand that wants ecommerce SEO run beside Google Shopping and paid search, with one agency reporting on organic revenue. It names the most retail brands here.

• Where they are: It says it has "some of Melbourne's best SEO specialists in-house" and works with stores "across Australia".
• What they sell: Ecommerce SEO for Shopify, Magento, BigCommerce and WooCommerce, from crawl and indexation fixes at scale to category and product content, plus PPC and Shopping.
• Proof they publish: Sydney Tools shows "+92% increase in organic revenue" and "+103% increase in completed online transactions", and Mattel Australia "+198% Increase in non-branded traffic year-on-year". Acer shows "+159% increase in online revenue in five months".
• Pricing: Not published. The page says it reports "on organic revenue rather than rankings, with pricing tied to performance".
• AI search: A Kudosity case study shows "+370% Growth in ChatGPT traffic". Kudosity sells software rather than products, so ask Impressive for an AI search result from a store like yours before you lean on it.
• Store rules: Its service list includes "Google Merchant Center optimisation", "Google Organic Shopping SEO" and "Google Customer Reviews optimisation".
• Ask them: How does performance pricing work: what's the baseline, and what counts as SEO revenue?

5. Megantic: best for large catalogues and high-stakes migrations

Megantic suits a retailer with a big catalogue, or one planning a platform move, that can't afford to lose rankings or revenue on the way. Its homepage leads with ecommerce and calls itself "3 Years Running, 'Best eCommerce Agency of the Year'".

• Where they are: Its homepage shows testimonials from The Good Guys, Go Vita and Wahu but no address, so ask where your team sits.
• What they sell: Technical SEO, AEO and GEO "for ambitious online retailers", plus migrations. It claims "+15 years Organic search experience" and offers a 2026 whitepaper made "in partnership with Shopify".
• Proof they publish: The House of Golf, "133% growth in Top 3 rankings, 75% growth in first-page rankings, and a 33% increase in organic sessions" year on year. Nourished Life's CEO credits it with a move "from a 15-year-old custom build to Shopify".
• Pricing: Not published. It links to a "No lock in Contracts" policy.
• AI search: AEO and GEO strategies, with ChatGPT and Gemini named on the homepage.
• Store rules: It shows a Google Partners badge, and one review praises its work on "SEO & Google Shopping campaigns".
• Ask them: On a migration like Nourished Life's, how many legacy URLs did you map? How did organic revenue track in the first 90 days?

6. Optimising: best for Shopify and Shopify Plus stores

Optimising suits a Shopify or Shopify Plus store that wants a technical SEO team that has worked inside the platform for years. No page I read is more Shopify-specific.

• Where they are: "We're based in Richmond, a few tram stops from Melbourne's CBD, and we've been doing SEO from here since 2008."
• What they sell: Shopify audits, technical SEO, migrations and ongoing campaigns with monthly reporting. It names Shopify's URL paths, app bloat and a sitemap indexing issue as problems it fixes.
• Proof they publish: Chemist Warehouse, "75% organic traffic growth during a complex platform migration to Commercetools, with zero ranking loss". Henne, "30% YOY Revenue Growth". Cake Decorating Central, "434% Revenue Growth".
• Pricing: Not published.
• AI search: "AI search visibility for Shopify stores" across Google's AI Overviews, ChatGPT and Gemini.
• Store rules: "From structured data and JSON-LD implementation to diagnosing complex hreflang issues for multi-region Shopify stores." It says it's "One of Australia's first Shopify Plus SEO Partners".
• Ask them: Which apps on my store are costing me crawl budget, and what would you remove first?

7. Spicy Web: best for stores that want a starting price upfront

Spicy Web suits a mid-size store that wants to know the entry price for ecommerce SEO before it books the first call. No other agency here publishes one.

• Where they are: "Melbourne-based", working "From our office by the beach in Melbourne". It names five of its SEO people on the page, led by Head of SEO Jase Porter, who brings "over 20 years of experience".
• What they sell: Ecommerce SEO across Shopify, WooCommerce, Magento, BigCommerce and custom stores: technical SEO, product and category pages and content strategy.
• Proof they publish: Racer Industries shows a "240% Increase in Organic Revenue", Manovella a "66% Increase in Organic Shopping Traffic" and Fibonacci "a 312% increase in organic conversions".
• Pricing: "from $2200 Per Month", and the page doesn't say whether GST is included.
• AI search: It says site structure, "accurate product schema, and genuine content give AI tools like ChatGPT and Google's AI Overviews something real to reference".
• Store rules: Product schema, as above. The page I read doesn't cover Merchant Center or the ACCC.
• Ask them: What does the $2,200 month include, in pages and fixes shipped?

8. Online Marketing Gurus: best for SEO, paid media and revenue reporting together

Online Marketing Gurus suits a store that wants SEO run beside Google Shopping and Meta ads, with one dashboard for organic revenue. It says "Every case study we publish has a named client, a real timeframe, and a specific number."

• Where they are: Its page shows its team in "the Sydney office".
• What they sell: Category and product architecture, technical SEO for large catalogues, content, links "from real Australian publications" and platform SEO. Its own tool, Gurulytics, reports organic revenue "channel-by-channel, in real time" rather than in a PDF at the end of the month.
• Proof they publish: Calvin Klein, "142% Increase in Organic Revenue" and "52% Increase in Organic Traffic". It claims "$170M+ tracked revenue" for SEO clients.
• Pricing: Not published. It offers a free review "valued at $4,000" and lays out a six-month roadmap.
• AI search: Wamada Jewellery, a "762% Increase in ChatGPT-Attributed Revenue" from AI SEO and GEO work.
• Store rules: Its FAQ covers running SEO beside Google Shopping and Meta ads, and product schema appears in its technical foundation step.
• Ask them: How does Gurulytics decide which sales count as ChatGPT-attributed?

How do these agencies compare on proof and store rules?

Most publish strong store results. Fewer show their working on the rules a store sells under, from product schema to the ACCC's price and review rules. Here's what each page shows.

"Ask" means the page I read didn't cover it. The agency may still do the work well, so put the question to them on the call and listen to how they answer.

How should you choose an ecommerce SEO agency?

Choose the agency that shows organic revenue from a store like yours, names the first pages it would build and proves its numbers. Use these five checks on every call.

1. Ask for a store like yours. A 300% result on a fashion label tells a hardware store little, so ask for the category, catalogue size, platform and time period behind it.
2. Ask which pages they'll build first. Collection pages carry product-type searches, and product pages carry model searches. A good agency names the collections it would build or rebuild from your own Search Console data, before you sign anything.
3. Ask how they handle filters. Every colour, size and sort option can create its own URL. Ask which filter pages they'd let Google index, and how they'd stop thousands of near-duplicate filter URLs eating Googlebot's visits to your store.
4. Ask about the rules. Product schema has to match the price and stock a shopper sees. Ask how they handle sold-out products, sale prices and review requests under the ACCC's rules.
5. Ask them to prove the tracking. Revenue claims are only as good as the analytics behind them.

That last check matters. A client's four enquiry types never counted as conversions. Their event names ran 41 to 50 characters; GA4 cuts at 40. The 40-character "career" event counted every time. Nobody had noticed, because the events still showed up. A store with an over-long purchase or add-to-cart event name has exactly the same blind spot, and its reports would undercount sales.

AI traffic needs the same care. A client's GA4 showed AI-assistant visits jump from 354 to 6,050 in a month. Almost none of it was real. About 5,700 came in three one-hour bursts: same 1920x1080 desktop Chrome, all new users, no referrer, about 20 seconds each, landing on two pages. Real AI traffic was 385 sessions against 354 the month before, roughly flat. So when an agency shows you ChatGPT growth, ask how it filtered out bots before it counted a single visit as real.

What do ecommerce SEO services cost in Australia?

Published Australian ecommerce SEO prices start at about $1,000 to $2,200 a month, and larger retail campaigns run well past $5,000. Most agencies quote after a call. Here's what the pages I read publish.

These are offers from the providers in the table, not a national average. The HyperSpace figures come from a third-party directory (HyperSpace), not from the agencies' own pages, so confirm them with each agency.

What moves the price is the work. A small Shopify store that needs collection pages and schema fixes sits near the bottom of that range, close to the published starting prices. A catalogue of tens of thousands of products, a platform migration, or digital PR for links pushes it up. Ask each agency what a month buys in pages and fixes shipped. Compare that, not the fee alone.
