Agency Comparison
Top B2B SEO Agencies for SaaS Companies (2026)
Why this list is different
If you're a Series A+ SaaS founder or VP Marketing evaluating SEO for B2B SaaS companies, you've probably noticed something: every agency claims to “specialize in SaaS.” Most don't. They slap a SaaS label on the same playbook they run for ecommerce and local businesses.
We built this list differently. Instead of collecting logos and self-reported claims, we used Ahrefs data (pulled February 2026) to analyze what each agency's content actually does — their organic traffic, the keywords they rank for, their content strategy, and whether they have any AI search (AEO) capability. The result is a more honest picture of the B2B SaaS SEO landscape.
A note on transparency: we include XEO on this list. XEO is a focused consulting practice, not an agency. We're not ranking ourselves #1 — we're listed alongside these agencies so you can evaluate all your options in one place. The difference between an agency and a consultant is covered in the “How to Choose” section below.

How We Evaluated These Agencies
We used four criteria. Each one is designed to cut through marketing claims and measure actual capability — because when it comes to SEO agencies, their own organic performance is the best proof of competence.
| Criterion | What We Measured | Why It Matters |
|---|---|---|
| SaaS Specialization | % of content targeting SaaS/B2B keywords vs. generic terms | A real SaaS SEO agency has content focused on SaaS problems, not just generic SEO advice |
| Organic Performance | Estimated monthly traffic, page 1 keywords, traffic value (Ahrefs data) | An SEO agency that can't rank its own site is a red flag — their own performance is the best case study |
| Content Strategy | URL patterns, content types (glossary, listicle, service), topical depth | The content strategy an agency uses for itself reveals the strategy they'll use for you |
| AEO Capability | AI search optimization pages, schema implementation, structured content patterns | AI search is the next frontier — agencies without AEO capability are already behind |
Data source: Ahrefs, pulled February 11, 2026. Traffic estimates are Ahrefs projections and may differ from actual analytics. Services, pricing, and client information marked [UNVERIFIED] require independent verification before relying on them for decisions.

XEO
xeo.works
Best for: Series A+ B2B SaaS companies that want a senior strategist (not an agency) with integrated SEO + AEO
Full transparency: this is our practice. XEO is a focused consultancy, not a full-service agency. What we offer is different from the agencies above — one senior strategist who builds your entire content engine, including both traditional SEO and AEO (AI Engine Optimization). If you need a team of 10 executing across paid, organic, and creative, we're not the right fit. If you want one experienced person who handles strategy and execution for organic growth, that's what we do. Our AEO methodology is designed to get your content cited by ChatGPT, Perplexity, and Claude — a capability most agencies on this list don't offer yet.

How to Choose: Agency vs. Consultant
The right choice depends on what stage you're at and what you need. Here's how we think about it:
Choose an agency when...
- You need multiple channels executed simultaneously (SEO + paid + design)
- You have budget for a larger team and want to move fast across channels
- You want established processes and playbooks from day one
- You need geographic-specific campaigns (multiple markets)
Choose a consultant when...
- You want direct access to a senior strategist, not a junior account manager
- Your focus is organic growth (SEO + AEO + content), not multi-channel
- You value depth of attention over breadth of services
- You want strategy and execution from the same person
Neither model is inherently better. The worst outcome is hiring a big agency when you need deep attention, or hiring a solo consultant when you need a team of 10. Match the engagement model to your actual needs.
The AEO Factor: Why It Matters When Choosing an Agency
Here's the uncomfortable truth about most agencies on this list: they don't have a formal AEO optimization offering. As of early 2026, AI Engine Optimization is still an emerging discipline — the keyword “aeo services” has 600 monthly searches with zero keyword difficulty. Nobody owns this category yet.
That will change. As AI search adoption grows, the agencies that build AEO capability now will have a significant advantage — and so will their clients. When you're evaluating agencies, ask them specifically: “What is your approach to AI search optimization? How do you ensure my content gets cited by ChatGPT, Perplexity, and Claude?” If the answer is blank stares, that tells you something.
AEO isn't a separate project from SEO — it's an additional optimization layer. The same content that ranks in Google can be structured for AI citation. The question is whether your agency knows how to do both. For a deeper look at the methodology, see how the XEO Content Engine integrates SEO and AEO in a single workflow.
