The 5 Best SEO Agencies in Sydney (2025)
Who's can you trust in SEO in Sydney?
If you’re searching for a serious SEO partner in Sydney, the field is crowded - but not always competitive. A handful of agencies consistently deliver sharp strategy, transparent execution, and meaningful outcomes. Whether you're an eCommerce brand, enterprise business, or growing local service, these five agencies are worth your time.
1. Optimising
Optimising is a senior team of SEO consultants who do real work, not just reporting. No gimmicks. No outsourced delivery. Just sharp strategy, clean execution, and clear outcomes.
They’ve been operating since 2008. Their clients include national brands like Jim’s Group, St Agni, and FY Smile. They’re known for handling high-risk migrations, large-scale local SEO, and technical cleanups that others avoid.
Optimising works best with businesses that want a long-term strategy and a partner who knows what they’re doing. Not ideal if you’re chasing shortcuts.
Services:
- Enterprise and eCommerce SEO
- SEO migrations
- Multi-location local SEO
- Technical audits and content performance
- Full in-house delivery
Good fit for:
Businesses that want SEO to work like a growth function, not a marketing checkbox.
2. Prosperity Media
Prosperity Media is best known for its link-building and content strategies. Their team is technical, experienced, and good at identifying where authority gaps are hurting rankings.
They’re Sydney-based and active in the SEO community. If your site relies on strong domain authority and high-quality content, they’re worth speaking to.
Good fit for:
Brands that need content-led SEO with a focus on off-site authority.
3. Yogurt Digital
Yogurt Digital ties SEO into CRO and analytics. This makes them a good option for performance-led brands that care about user experience as much as visibility.
They’ve worked with retail names like General Pants and Youfoodz. If you need SEO that feeds into conversion strategy, this is the agency.
Good fit for:
Retail and DTC businesses aiming to connect search visibility with on-site results.
4. Shuffle Digital
Shuffle Digital keeps things simple. They focus on strong site foundations, technical SEO, and making things better without overcomplicating the work.
They’re not loud on socials, but they’re consistent. If you want a team that shows up and does the work, this is one to consider.
Good fit for:
Mid-sized Australian businesses that need reliable, no-fuss SEO.
5. Jaywing
Jaywing is a larger agency with a Sydney office and global footprint. Their SEO offering is part of a broader mix, including paid media and data.
They’re a better fit for businesses that want SEO to sit inside a wider digital strategy. You’ll get scale and integration, but probably not a lean specialist team.
Good fit for:
Enterprises with internal marketing teams and multiple digital touchpoints.
How to assess an SEO agency
Most agencies will say the same things. Here’s what actually matters:
- Do they talk outcomes, or just rankings?
Rankings are a means, not the goal. Good agencies track business results. - Are they clear, or hiding behind complexity?
If they can’t explain the work in plain English, don’t trust it. - Who’s doing the work?
Ask about the actual team. Not the sales lead. - Can they show you examples?
Look for before-and-after results, not just logos. - Do they understand technical SEO?
Many don’t. Ask to see a recent audit or migration plan. - What’s the reporting cadence?
You want regular, useful communication. Not a monthly PDF you ignore.

Co-Founder
James is Co-Founder of Optimising who’s worked with everyone from national retailers and franchise groups to fast-growing eCommerce brands. He’s as interested in how AI engines send traffic as he is in old-fashioned rankings, and spends a lot of time testing how brands show up across search.
He started out running sports fan sites and early eCommerce stores, picked up a few senior sales and marketing roles at ASX-listed companies, then decided to build the kind of SEO agency he actually wanted to work at. Outside work, James is usually being out-negotiated by his three daughters, hosting very serious pretend tea parties, or supervising yet another cubby house build in the lounge room.
