With e-commerce making up over 18% of all retail sales, the best SEO agencies have one goal: to make you more money. Who follows through?
Shopify has SEO-friendly features, themes, and plugins, but they aren’t enough to rank in competitive Google search results pages and attract customers. Solo SEO is fine for small operations, but you may need an agency if you’re struggling to grow.
Not all service providers are equal, and it’s easy to waste money on getting traffic without any business impact. Doing SEO for e-commerce requires a specific approach, and you want to find a team with experience driving qualified traffic to money pages.
A good SEO agency won’t just get you website traffic; they’ll help you acquire valuable users who buy products. They should be obsessed with your success. Check out our favorites, and read to the end for a buying guide if you’re struggling to make a choice.

Here’s what separates Siege Media from other e-commerce SEO agencies:

Our team creates data-driven research reports and visual assets that earn mentions from the high-authority publications your customers actually read, building the trust signals necessary to rank in competitive niches.

Why You Should Work With a Shopify SEO Agency
You can DIY some SEO practices with plugins, but it’s a complex discipline, and you’ll quickly find you need help to stay competitive. It’s tempting to use cheap services through online marketplaces like Fiverr.
Unfortunately, relying on cheap or inexperienced services can cost you more money in the long term. The wrong tactics can trigger ranking losses that hurt your traffic and sales.
There’s no substitute for expertise and time; it takes years of experience to master SEO best practices, and the Google algorithm is regularly changing.
SEO agencies have individual departments for the different aspects of SEO, such as content creation, design, and website development. They also employ people who stay up to date with the latest SEO and GEO trends, Google algorithm updates, and best practices.
The Google algorithm looks for a variety of factors to rank websites:
- Content quality, structure, and usefulness
- The site’s technical performance, accessibility, and security
- Links pointing to the website, as well as their quality and relevance
- User experience
- The site’s internal linking structure
Plus many more signals with varying weights. Optimizing websites to rank and convert users is quite a bit of work across multiple disciplines, which is why you may need to outsource SEO services for Shopify.
How To Choose a Shopify SEO Company
SEO can be daunting, but you don’t want to get burned by paying for an expensive service that offers no return.
While agencies can be expensive, the right partner will help you grow your business. SEO is an investment in your future profit, so return on investment is your guiding light.
Here’s a list of services agencies often provide:
- SEO consultation
- Keyword strategy
- Competitor analysis
- Landing and product page optimization
- Consistent, unique content publishing
- Technical performance auditing
- Data-driven reporting
- Shopify site layout optimization
- Link building
But it’s difficult to make decisions from lists of services alone. Dig deeper into your research and look for signals that the agency is trustworthy and experienced:
| Shopify SEO Agency Buying Guide | ||
|---|---|---|
| What to look for | Why | How it helps you |
| Experience with Shopify | Shopify is a proprietary platform that can make it more challenging to customize and set up your store for SEO success. | The agency can help you avoid common pitfalls and solve technical issues that impact SEO. |
| Product-focused SEO | E-commerce stores have different SEO needs to service businesses and publishers, and not all agencies have that experience. | The agency knows how to target competitive, purchase-intent queries and rank your product pages. |
| A team of specialists | SEO is a broad discipline that requires skills in technical, marketing, writing, design, and outreach. | Each team member brings genuine expertise and contributes to SEO rankings. |
| Branded case studies | Happy clients say “yes” to putting their names on case studies, and they prove that the agency can get results. | If you see case studies in your niche, you can be confident that the company has enough experience to help you. |
| Customized strategies and recommendations | SEO is not one-size-fits-all; every website has different needs, and an agency should justify every recommendation. | The agency isn’t just selling services; they know what you need to succeed based on your position in the market. |
| Digital PR strategy | Links are key for SEO, but building them ethically and sustainably is difficult. | DPR is high-impact link building that improves SEO, reputation, and AI discoverability. |
| Clear AI policy | Generative AI can improve efficiency, but it requires humans in the loop to ensure high-quality results. | You can be confident about the level of work and expertise going into each deliverable. |
| A plan for AI search | Modern SEO must account for the impact of AI Overviews and generative AI-based search. | A strong AI search strategy can generate qualified traffic from LLM chats. |
