10 Best SaaS SEO Agencies (2026)

Every list of the best SaaS SEO agencies is written the same way: a paragraph of praise per agency, a logo wall, no numbers. That is not an accident. When we checked the pricing pages of the ten agencies below, five publish no cost information at all, and only one publishes a rate card you could actually build a budget from.

So this list is sorted by something you can verify before a sales call: what each agency discloses, what it costs to start, and which stage it says it serves. Where an agency publishes nothing, we say so rather than filling the gap with a guess.

Disclosure: MentionAgent is our own product. It is software for outreach, not a SaaS SEO agency, so it is not ranked among the ten below. It appears at the end as the option for teams who are not ready for a retainer.

How to judge a SaaS SEO agency

Three questions separate the ones worth paying from the ones selling a logo wall.

1. Ask which stage they actually serve, and believe them when they rule you out. The most useful sentence on any of these sites is Virayo's admission that it is "not the right fit for pre-PMF or seed-stage startups". Kalungi does the same thing structurally, routing companies under $1M ARR into a self-serve program instead of full service. An agency that will take anyone's money is telling you something about how targeted the work will be.

2. Ask for referring pages, not authority scores. Several agencies on this list price link placements in DR bands. That is a tidy way to build a rate card and a poor way to predict results. Domain Rating describes a domain's overall link graph, not whether one specific page sends you readers who convert. A DR 70 page nobody reads is worth less than a DR 25 page whose audience is your buyer. Ask for placements that produced measurable referral traffic or trial signups for a client in your category. We make the fuller argument in relevant backlinks.

3. Work out what you are actually buying. "SaaS SEO" covers three different scopes at three different prices: content production, technical and on-page work, and link acquisition. Some agencies sell all three as one retainer. If your content is already handled and links are the gap, you are overpaying for the bundle, and a link building agency or software is the cheaper fit.

What AI visibility actually looks like right now

Almost every agency on this list now sells generative engine optimisation alongside SEO. Virayo, Omniscient, Skale, SimpleTiger and MADX all lead with it. Very few of them publish what the baseline looks like, so here is ours.

We run automated AI visibility scans for customers and store every answer. Across 4,388 scanned answers covering 1,312 distinct queries for 24 workspaces, measured to 25 August 2026:

Two things worth taking into an agency conversation. Brand mention rates are nearly identical across engines, between 4.4% and 5.0%, which cuts against pitches built around needing a separate strategy per engine. And ChatGPT cites no source at all in over a quarter of its answers, while Gemini and Claude cite something almost every time. Any agency measuring AI visibility on citations alone will systematically understate ChatGPT, which is the engine most of your buyers are actually using.

Method: scans run on the cost-efficient model tiers (gemini-2.5-flash, gpt-4o-mini, claude-haiku-4-5), not the flagship models, so treat these as the behaviour of the cheap tier rather than of ChatGPT at its best. Answers that errored are excluded.

Quick comparison

Entry costs are what each agency publishes on its own site at the time of writing. "Not published" means exactly that: the agency discloses no figure, not that it is cheap. Rate cards move and most of these quote on a call, so confirm before budgeting.

1. MADX Digital: the only public rate card

Published cost: $2,500/mo per pillar on annual billing, or $5,500/mo fully managed. Monthly billing is $3,500 per pillar and $7,500 fully managed. A one-off AI Search and SEO Growth Plan is $4,500, typically three to four weeks.

MADX splits its work into pillars you can buy separately: SEO and AI optimisation, content strategy and production, and link building and off-page. The pillars are the useful part, because you can buy only the piece you are missing instead of a bundle built around what the agency likes selling.

Best for: B2B SaaS teams who want to compare a number against their own budget before spending an hour on a sales call.

Trade-offs: Link placements are priced in DR bands, from $195 for DR20+ up to $965 for DR60+. That is the pricing model we argue against on this site, because the band tells you about the domain's link graph and nothing about whether its readers are your buyers. If you buy placements here, ask what traffic those pages actually get.

2. Virayo: a published floor and an honest exclusion

Published cost: "Engagements start at $7,500 per month with an initial six-month term, then month to month."

Virayo runs SaaS SEO, generative engine optimisation and PPC, with weekly visibility audits across AI systems on its own platform. It goes deepest in software development, healthcare, logistics and fintech, and describes its typical client as a PE-backed SaaS company around $50M in revenue.

Best for: Post-product-market-fit B2B SaaS, particularly vertical category leaders, that want AI search visibility handled alongside conventional SEO.

Trade-offs: The six-month initial term means the real commitment is $45,000, not $7,500. Virayo also states plainly that it is not the right fit for pre-PMF or seed-stage startups, which is worth taking at face value rather than trying to talk your way in.

3. Omniscient Digital: five figures a month, stated up front

Published cost: "Full-service engagements start at $10,000 a month."

Omniscient sells SEO strategy, GEO, programmatic and technical SEO, content production, digital PR, link building and CRO to B2B software companies. The positioning is that SEO and content should drive business growth rather than traffic, which is a common claim, though publishing the floor is not.

Best for: Funded B2B software companies building organic into a primary acquisition channel with a budget already approved.

Trade-offs: $10,000 a month is $120,000 a year, so this only makes sense when a single customer is worth a meaningful fraction of that. Third-party roundups report Omniscient engagements running higher than the published floor, so treat $10,000 as the entrance rather than the expectation.

4. SimpleTiger: priced as a percentage of your size

Published cost: No dollar figures. SimpleTiger states that "the SaaS industry average spend on SEO is a minimum of 8% of revenue or funding" and that "each of our SEO packages starts at 5% of revenue or funding at the respective growth stage".

Packages are tiered by stage, from Pipeline Startup through to Pipeline Enterprise, with a separate SEO and GEO/AEO ladder running Kickstart, Scale, Accelerate and Dominate. Everything is customised around content production, link building and consulting.

Best for: SaaS teams who would rather index spend to revenue or funding than negotiate a flat retainer.

Trade-offs: A percentage-of-funding model means the bill grows with your raise regardless of whether the channel has proven itself. You still cannot budget without a call, because 5% of revenue is only a number once you tell them your revenue.

5. Kalungi: a marketing function, not an SEO retainer

Published cost: No figures. Offers are banded by ARR: T2D3 for $0 to $1M ARR ("you do it with our systems"), Syntropy for $1M to $5M ARR ("we do it with you"), and Full-Service for $5M to $10M ARR ("we do it for you"). Kalungi notes pay-per-performance is available on full service.

Kalungi is a B2B SaaS marketing agency with CMO-as-a-service at the centre, and content and SEO as one workstream among branding, paid media, ABM and RevOps. It says it has worked with more than 150 SaaS companies.

Best for: SaaS companies that need a marketing function stood up, not a specialist pointed at organic search.

Trade-offs: If you already have a marketing team and want SEO specifically, you are buying a wider scope than you need. The ARR banding is genuinely useful for self-selection, and the honest read of the $0 to $1M tier is that they will sell you systems rather than do the work.

6. Skale: organic growth measured on pipeline

Published cost: Not published.

Skale covers SaaS SEO, generative engine optimisation, AI brand mentions, link building and outreach, content production and site migrations. It describes itself as an AI-search-first organic growth agency and frames its reporting around SQLs, pipeline and revenue rather than traffic and rankings.

Best for: Growth teams whose board asks about pipeline contribution rather than keyword positions, and who want AI mentions tracked alongside rankings.

Trade-offs: Nothing is published, so the first real number arrives on a call. Third-party roundups place Skale in the same five-figure territory as the rest of this tier, which is worth knowing before you book.

7. Animalz: content depth at enterprise scale

Published cost: Not published.

Animalz sells brand and authority work, SEO and answer engine optimisation, and content production and distribution to B2B SaaS. Its client roster includes Airtable, Amplitude, Atlassian and Google, which tells you where the price sits without anyone printing it.

Best for: Established B2B SaaS running a serious content programme where quality and editorial judgement matter more than cost per article.

Trade-offs: This is a content agency that earns search visibility, not a link acquisition service. If your gap is authority rather than content, you would be buying the wrong end of the problem.

8. TripleDart: one vendor across organic and paid

Published cost: Not published. TripleDart says it manages between $10K and $500K in monthly spend for clients, which sets the scale of engagement.

TripleDart runs organic growth, paid media and ABM, and GTM engineering covering data pipelines and attribution. It positions as an AI-native B2B marketing agency and says it has worked with more than 300 companies across SaaS, fintech and enterprise tech.

Best for: SaaS teams who want organic, paid and attribution owned by one vendor instead of stitched together across three.

Trade-offs: Breadth cuts both ways. If SEO is the only thing you need, a multi-channel agency is a wider contract than the problem calls for.

9. Grow and Convert: conversions over traffic

Published cost: Not published.

Grow and Convert sells content SEO and AI search, link building, AI citation outreach and paid search, and says it has worked with more than 100 clients over ten-plus years across B2B, self-serve and demo-led SaaS, services and ecommerce. The house argument is that content should be measured on conversions rather than traffic volume, which shows up in how they pick topics.

Best for: Teams tired of traffic reports that never map to signups, and who want bottom-of-funnel topics prioritised over volume.

Trade-offs: Not SaaS-exclusive, so the category depth is broader and shallower than a dedicated SaaS shop. No published pricing.

10. Directive Consulting: SEO inside a performance mix

Published cost: Not published.

Directive runs performance marketing across content, paid media, creative and RevOps, with separate commerce and communications divisions. It works with B2B technology, industrial and professional services companies and says it has served more than 420 brands including Calendly, Adobe and Cisco.

Best for: Larger B2B organisations buying the whole channel mix, where SEO is one line in a bigger performance contract.

Trade-offs: SEO is not the headline product here. For a SaaS team whose single question is organic growth, a specialist will give the channel more attention.

What this actually costs

Strip out the positioning and the numbers land in three tiers.

A single pillar starts around $2,500 a month. That is $30,000 a year for one workstream, and MADX is the only agency here that will tell you so before a call.

Full service starts between $7,500 and $10,000 a month. Virayo and Omniscient both publish floors in that band. With Virayo's six-month initial term, the smallest real commitment on this page is $45,000.

Everything else is quoted to your size. SimpleTiger indexes to revenue or funding, Kalungi to ARR, and five agencies publish nothing. Third-party roundups report ranges above the published floors, which is worth remembering: a listicle is not a quote, including this one.

The pattern worth noticing is that none of these get cheaper per unit as you scale. Retainers are priced to your size, so growing the company grows the bill whether or not the channel is the thing that grew it. Our guide to what backlinks cost breaks down the link side of that maths.

If you are not ready for a retainer

Every agency above is someone else running your organic channel at five figures a year and up. Several of them will tell you directly that early-stage companies are not their client. That leaves a real gap, because the companies that most need backlinks are usually the ones that cannot sign a $45,000 commitment.

MentionAgent is $99/mo flat. The agent finds blog posts in your niche, looks up the author's verified email, writes a pitch tied to that specific post, and sends it once you approve it in Telegram. Follow-ups run until someone replies. There are no credits, no per-contact fees and no per-link pricing, so the bill does not move when the volume does.

It is a narrower product than anything on this list. It does outreach: it does not write your pillar pages, fix your site speed or build a keyword strategy. If links are the gap, that narrowness is the point. If you need the whole channel run, hire one of the ten above. We wrote the honest version of that comparison in AI link building vs hiring an agency, including where the agency wins.

How to pick

Frequently asked questions

What is the best SaaS SEO agency in 2026?

There is no single best one, because they split by the stage they serve and how much they disclose. Virayo publishes a $7,500 per month floor with a six-month initial term and says outright it is not a fit for pre-PMF or seed-stage companies. Omniscient Digital starts full-service engagements at $10,000 a month. MADX Digital publishes a full rate card from $2,500 per month per pillar. Kalungi bands its offers by ARR. SimpleTiger prices as a percentage of revenue or funding. The other five quote only on a call.

How much does a SaaS SEO agency cost?

Where agencies publish a figure, entry points run from roughly $2,500 per month for a single service pillar to $10,000 per month for full service. Most publish nothing. Third-party roundups report ranges above the published floors, which is a reason to get a quote rather than budget from a listicle. Either way a dedicated SaaS SEO retainer is a five-figure annual commitment before you have measured a single conversion.

Should I judge a SaaS SEO agency by the DR of the links it builds?

No. Domain Rating describes a domain's overall link graph, not whether a specific page sends you anything. Several agencies price placements in DR bands because it makes a clean rate card, not because it predicts results. Ask for referring pages that produced measurable referral traffic or signups for a client in your category.

What is the difference between a SaaS SEO agency and a link building agency?

A SaaS SEO agency owns the whole organic channel: keyword strategy, content, technical work and increasingly AI search visibility, with links as one input. A link building agency sells placements and leaves the rest to you. The SaaS agencies cost more because the scope is larger. If content and technical work are already handled and links are the gap, a link building service is the cheaper fit.

Is a SaaS SEO agency worth it for an early-stage startup?

Usually not at the retainer tier, and several of these agencies say so themselves. Virayo states it is not the right fit for pre-PMF or seed-stage startups, and Kalungi routes companies under $1M ARR into a self-serve program. Before product-market fit the constraint is rarely organic search. Early teams tend to do better running outreach themselves or buying a few placements to test the channel.
