With e-commerce making up over 18% of all retail sales, the best SEO and GEO agencies have one goal: to make you more money. Who follows through?
Shopify’s built-in SEO tools can only take you so far. They handle basics like sitemaps and alt text, but they can’t build the content depth or structured data that competitive rankings and AI citations require.
Product research increasingly starts with an AI search instead of a scroll through Google results. That shift is why generative engine optimization (GEO) has become just as critical as traditional SEO for e-commerce brands.
GEO means optimizing content so AI platforms surface and cite it. Solo SEO is fine for small operations, but you may need an agency if you’re struggling to grow across both channels.
Not all service providers are equal, and it’s easy to waste money on traffic that never turns into revenue. SEO and GEO for e-commerce require a specific approach. You want a team with experience driving qualified traffic to your money pages, not just your blog.
A good agency will help you acquire users who buy products. Check out our favorites, and read to the end for a buying guide if you’re struggling to make a choice.

1. Siege Media
- Best for: Full-service GEO
- Headquartered in: Austin, San Francisco, New York, and Chicago
- Recognizable clients: Instacart, Angi, Shutterfly
Siege Media is a full-service GEO agency that applies the same rigor to Shopify stores that we bring to our biggest SaaS and e-commerce clients. That’s the rigor that helped Instacart lead its competitors in LLM presence and AI Overview citations, and drove a $7.2M monthly traffic value for Zapier. We treat every Shopify store like the same high-stakes investment.
Here’s what separates Siege Media from other e-commerce SEO agencies:
- Proprietary strategy via BlueprintIQ: We built BlueprintIQ to remove the guesswork from content marketing. This tool allows us to pinpoint the exact content gaps where your brand can outpace competitors and forecast the actual ROI of every piece of content before we even write it.
- DataFlywheel for content freshness: In 2026, Google and AI engines penalize stagnant content. Our DataFlywheel system automates the identification and updating of your best-converting pages, helping your top-performing articles stay fresh and maintain their year-over-year rankings.
- Generative engine optimization (GEO): Ranking on page one is only half the battle. We specialize in GEO to ensure your products are the top recommendations when users ask AI tools like ChatGPT or Gemini for buying advice. We focus on citation-worthy content that LLMs prioritize.
- Digital PR that builds real authority: We don’t deal in low-quality, spammy backlinks. 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.
- Affiliate partnerships that earn LLM visibility, not just commissions: Most affiliate agencies stop at the sale. We recruit publishers and creators who already get cited when AI platforms answer “what’s the best [X]?” — so every partnership pays off twice.
- A full-stack, implementation-heavy team: You get more than just a strategist. Our dedicated team of in-house designers, developers, and editors handles the actual implementation, from custom page templates to complex schema.
- Reddit strategy without gray-hat shortcuts: Reddit is now one of the most-cited sources in AI shopping answers. We help brands earn real influence there through disclosed accounts and genuine community contributions, not fake reviews or vote manipulation.
If you’re looking for a partner that balances technical precision with high-end creative execution, we’re the team that makes it happen.

Why You Should Work With a Shopify SEO & GEO 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. GEO adds another layer of complexity to SEO. GEO is a newer discipline, and most store owners have no framework for approaching it.
It’s tempting to use cheap services through online marketplaces like Fiverr. But relying on cheap or inexperienced help usually costs more in the long run. The wrong tactics can trigger ranking losses that hurt your traffic and sales, and getting cited by AI platforms isn’t something a low-cost freelancer can reliably deliver either.
There’s no substitute for expertise and time. SEO takes years to master, and Google’s algorithm changes constantly. But AI platforms adjust even faster. They’re still refining how they select and cite sources, so what earns a citation on ChatGPT today may not work in three months.
SEO and GEO agencies solve this by splitting the work across dedicated teams for content creation, design, and website development, staffed by people who track algorithm updates and shifting AI citation patterns full-time.
Search engines and AI platforms don’t reward the exact same things, but they overlap more than you’d expect. Both prioritize:
- 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
Optimizing a store to rank in search results and get cited in AI answers is a lot of work across multiple disciplines. That’s exactly why outsourcing SEO and GEO for Shopify often makes sense.
How To Choose a Shopify SEO & GEO Company
SEO can overwhelm store owners, and GEO is a new search tool that’s still evolving. You don’t want to get burned by paying for an expensive service that offers no return on either front.
While agencies can be expensive, the right partner will help you grow your business across both search and AI platforms. SEO and GEO are investments in your future profit, so returns are your guiding light.
Here’s a quick breakdown of what agencies typically offer, split by discipline:
| SEO services | GEO services |
|---|---|
| Keyword strategy | AI citation tracking and reporting |
| Digital PR-driven link earning | Digital PR built for AI source authority |
| Landing page and product page optimization | Brand mention monitoring across AI platforms |
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 in both disciplines:
| What to look for | Why it matters | How it helps you |
|---|---|---|
| Experience with Shopify | Shopify is a proprietary platform that can make it more challenging to customize and set up for SEO and GEO success. | The agency can help you avoid common pitfalls and solve technical issues that impact both rankings and AI visibility. |
| Product-focused SEO and GEO | E-commerce stores have different needs from service businesses or publishers, and AI platforms cite product content differently from blog content. | The agency knows how to target purchase-intent queries and get your products recommended in AI answers, not just ranked on Page One. |
| A GEO methodology built in, not bolted on | Many agencies still treat GEO as an experimental add-on rather than a core part of strategy. | You get content built for AI citation from the start, instead of retrofitted later. |
| A team of specialists | SEO and GEO both require skills in technical, marketing, writing, design, and outreach. | Each team member brings genuine expertise instead of one generalist covering everything. |
| In-house production | Design, development, and editorial work are often outsourced piecemeal by smaller shops. | An in-house team moves faster and keeps quality consistent across a large content library. |
| Branded case studies | Happy clients say “yes” to putting their names on case studies, and they prove the agency gets results. | Case studies in your niche give you confidence that the agency has relevant experience. |
| Proprietary tools or research | Some agencies rely entirely on third-party platforms like Ahrefs or Semrush. | Proprietary tooling can surface opportunities that competitors relying on the same off-the-shelf tools will miss. |
| 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 at once. |
| Clear AI policy | Generative AI can improve efficiency, but it requires humans in the loop to ensure high-quality results. | You can feel confident in the level of work and expertise that goes into each deliverable. |
| A dedicated GEO reporting stack | Most reporting still stops at traffic and rankings. | You can see AI citation share and brand mentions across platforms, not just where you land on Google. |
Expand Your Reach With Shopify SEO & GEO
The right agency depends on your bottleneck. If your technical foundation is solid but you aren’t outranking competitors, you need content-led growth. If you rank well but never show up when someone asks ChatGPT or Perplexity for a recommendation, you need GEO built into the strategy, not bolted on.
At Siege Media, we treat your search and AI presence as a revenue driver.. Our team helps your store earn both page-one rankings and AI citations. If you’re ready to scale your organic performance, check out our e-commerce GEO services to see how we can help your business thrive.
