Melbourne has one of the most competitive digital landscapes in Australia, and for online stores, that makes choosing an SEO partner genuinely hard. Everyone claims to do eCommerce SEO.

Far fewer actually specialise in it.

eCommerce SEO is its own discipline. It is not the same as ranking a blog or a service page. It means optimising product and category pages, fixing the technical issues that slow large catalogs, earning authority in crowded categories, and tying all of it back to revenue rather than vanity metrics.

To make this list useful, I focused on agencies with real eCommerce experience, a Melbourne presence, and a clear track record with online retailers. Below are seven worth shortlisting in 2026, what each is good at, and who each suits best.

Key takeaways

• Spicy Web is my top pick for revenue-focused online stores that want direct access to eCommerce SEO specialists and no lock-in contracts.
• StudioHawk suits retailers that want Australia's largest dedicated SEO team and a fundamentals-first approach.
• Megantic is the pure-play choice, since it works on eCommerce organic search and nothing else.
• Calibre Nine is a strong fit for mid-sized fashion and retail brands that value transparency and local support.
• Sixgun, Impressive, and Optimising round out the list for stores that want boutique service, performance-linked pricing, or SEO run as a senior-led growth function.

How I compared these agencies

eCommerce specialisation. I prioritised teams that work on online stores specifically, not generalists who treat eCommerce as one service among many.

Revenue focus. The best agencies report on sales, conversions, and returns, not just rankings and traffic.

Technical and on-page depth. Product and category pages, site speed, crawlability, schema, and CRO all matter for a store.

Proof and fit. I looked at case studies, clients, and awards, then summarised which agency suits each best, so you can match one to your store.

1. Spicy Web

Based in: Melbourne

Spicy Web is a Melbourne eCommerce SEO agency built around revenue rather than vanity metrics, with a team working from an office by the beach.

The pitch is refreshingly direct. You work with eCommerce SEO specialists rather than generalists, reporting centres on revenue and profit, and there are no lock-in contracts, so you keep full ownership of your campaigns and data.

Their process maps neatly to what a store actually needs. It runs from keyword research and a technical site audit through product and category page optimisation, user experience and CRO, schema markup and rich snippets, and link building. They cover the platforms retailers use, including Shopify, and offer local, international, enterprise and migration SEO for online stores.

The results back it up. Spicy Web's published case studies include a 312 percent increase in organic conversions for Fibonacci, a 240 percent increase in organic revenue for Racer Industries, and a 66 percent increase in organic shopping traffic for Manovella.

On credibility, the agency has more than 100 five-star client reviews and is a Google Partner as well as an Ahrefs and SEMrush partner. eCommerce SEO starts from $2,200 a month, and a free eCommerce SEO audit lets you see where your store stands first.

Best for: Online stores that want hands-on, revenue-focused eCommerce SEO with transparent reporting and no lock-in contracts.

2. StudioHawk

Founded: 2015
Based in: Prahran, Melbourne

StudioHawk is one of Australia's largest dedicated SEO agencies, founded by Harry Sanders and now spread across offices in Melbourne, Sydney, London and Atlanta.

It is SEO-only by design. There are no account managers, so you work directly with the specialists doing the work, and the agency built its reputation on mastering fundamentals rather than chasing quick wins. Its eCommerce page states the team delivers an average 300 percent ROI for clients.

For online retailers, the eCommerce offering covers site architecture, product and category optimisation, technical SEO, link building and content. The agency has worked with major Australian retail brands including Aje, Clarks and Officeworks, and has collected APAC Search and Semrush recognition.

Best for: Established retailers that want a large, specialist SEO team and a fundamentals-first process.

3. Megantic

Based in: Melbourne

Megantic is the most specialised name on this list. It describes itself as the only eCommerce-focused organic search specialist in Australia, and it works on eCommerce SEO alone, with no Google Ads, social or web builds.

That singular focus shows in its scale. Megantic is headquartered in Melbourne with offices in the UK and Canada, and reports working with more than 500 clients across dozens of eCommerce industries, with specialists allocated to each account in dedicated groups. It is certified across Shopify, WooCommerce and Magento.

The trade-off is that it tends to suit retailers ready for a higher minimum spend, with listings on agency directories placing it at the premium end of the market.

Best for: Online retailers that want a pure-play eCommerce SEO specialist and nothing else.

4. Calibre Nine

Based in: Collingwood, Melbourne

Calibre Nine is a specialist SEO agency with a strong eCommerce streak. It has won APAC Search Awards for its eCommerce SEO work with fashion brand Ghanda, which is a useful signal in a competitive retail category.

The agency has built a reputation for being transparent, responsive and no-nonsense, and its team has grown quickly. For mid-sized retailers, that combination of local support and a clear eCommerce focus is appealing.

Best for: Mid-sized eCommerce and retail brands that value transparency and a local Melbourne team.

5. Sixgun

Founded: 2017
Based in: Richmond, Melbourne

Sixgun is a boutique Melbourne agency founded by David Pagotto. SEO is its core strength, but it also offers SEM, social, content and CRO for clients that want broader support.

The approach is collaborative and partner-style, with dedicated specialists assigned to each account rather than rotating teams, and a focus on technical foundations and sustainable growth over quick wins. That makes it a good fit for stores that want a closer working relationship.

Best for: Retailers that want a smaller, relationship-driven agency with a solid technical foundation and optional broader channels.

6. Impressive

Founded: 2016
Based in: Melbourne

Impressive is one of Australia's larger full-service agencies, with SEO sitting alongside paid media, social, CRO and email. It is Melbourne-based with a national footprint and a US office.

Its reputation rests on integrating channels rather than running them in silos, and it offers a performance-linked fee structure that ties cost to agreed targets rather than flat retainers. It is also B Corp certified and has earned Deloitte Technology Fast 50 recognition across several years.

Best for: Stores that want eCommerce SEO managed alongside paid channels, with fees tied to outcomes.

7. Optimising

Founded: 2008
Based in: Richmond, Melbourne

Optimising is a long-running, SEO-only agency with an all-senior, in-house team and no account managers. It handles enterprise and eCommerce SEO, platform migrations, multi-location SEO and AI search visibility.

It is B Corp certified and a Shopify Plus Partner, and its client list includes large national brands.

The senior-led model suits businesses that want SEO treated as a growth function rather than a checklist.

Best for: Brands that want senior, in-house SEO talent and experience with complex migrations and enterprise stores.

How to choose the right one for your store

Start with your biggest gap, then match the agency to it.

If you want a hands-on, revenue-focused specialist with flexible terms, start with Spicy Web. If you want scale and a large dedicated SEO team, look at StudioHawk. If you want a pure eCommerce specialist, Megantic fits. If you are a mid-sized retailer that values local support, Calibre Nine is worth a call. For broader channel support, Sixgun and Impressive bring more than SEO, and Optimising suits senior-led enterprise work.

Whichever you shortlist, ask for case studies with real numbers, confirm who will actually work on your account, and check whether you are tied into a lock-in contract or keep ownership of your data.

Frequently asked questions

What is eCommerce SEO?

It is the process of optimising an online store to rank higher in search results, with a focus on product and category pages so the site attracts qualified traffic and converts visitors into customers.

How is eCommerce SEO different from regular SEO?

A store has challenges a blog does not, including large product catalogs, category structure, faceted navigation and product schema. eCommerce SEO is built around converting shoppers, not just attracting readers.

How much does eCommerce SEO cost in Melbourne?

It is usually a monthly retainer that scales with scope and store size. As a reference point, Spicy Web lists eCommerce SEO from $2,200 a month, while some specialist agencies sit higher.

Confirm current pricing and inclusions before committing.

How long does eCommerce SEO take to work?

SEO is a medium-term investment rather than an overnight fix. Most stores see meaningful movement build over several months, with larger gains compounding across the first year as technical fixes, content and authority add up.

Should I choose a specialist or a full-service agency?

If SEO is your priority channel, a specialist usually goes deeper. If you want SEO managed alongside paid media and social, a full-service agency can integrate those channels.

Do I need an agency that knows Shopify?

If you sell on Shopify, platform-specific knowledge helps, since Shopify has common technical SEO quirks that a specialist can resolve quickly.

The bottom line

The best eCommerce SEO agency for your store is the one that specialises in online retail, ties its work to revenue, handles the technical foundations and can show real results with stores like yours.

Define what your store needs, ask the direct questions above, and look for proof rather than promises. For Melbourne retailers who want a specialist team with transparent reporting and no lock-in contracts, Spicy Web is a strong place to start, with StudioHawk, Megantic, Calibre Nine, Sixgun, Impressive and Optimising each making sense depending on your size, budget and goals.
