Siteimprove Pricing in 2026: Reported Ranges, Modules, and Questions to Ask

Last updated: October 7, 2026

Siteimprove does not publish its pricing; as of August 2026, procurement marketplace data reports an average contract of roughly $15,600 per year, with deployments reported from about $15,000 for a single-module program to $150,000 or more annually for multi-module enterprise portfolios (Vendr). This page aggregates what the public record shows — reported contract ranges, module-level pricing, and directory listings — plus what drives a Siteimprove quote and the questions worth asking before you sign.

Key numbers: The average reported Siteimprove contract is roughly $15,600 per year, with deployments ranging from about $15,000 for smaller single-module programs to $150,000+ for multi-module enterprise portfolios (Vendr, procurement data as of August 2026). Buyer-reported figures put the Accessibility module alone at $12,000–$70,000 per year depending on page volume, with SEO or Quality Assurance modules adding another $8,000–$25,000 annually (Vendr, as of August 2026). Renewal escalators of 3–7% per year and multi-year discounts of 10–25% are typical in reported contracts (Vendr, as of August 2026). 94.8% of the top one million home pages had detectable WCAG failures in 2025, averaging 51 errors per page (WebAIM Million). Ecommerce and retail account for 69–77% of digital accessibility lawsuits (Seyfarth Shaw).

How much does Siteimprove cost in 2026?

Public procurement data as of August 2026 puts the average Siteimprove contract at roughly $15,600 per year, ranging from about $12,000 for single-module programs to $150,000+ for multi-module enterprise deployments (Vendr).

These are buyer-reported and directory-listed figures from Vendr's Siteimprove marketplace page, not numbers Siteimprove has confirmed. Treat them as calibration for your own negotiation, not a rate card.

Why doesn't Siteimprove publish its pricing?

Siteimprove prices by private quote, standard at the enterprise digital-governance tier: as of August 2026, Capterra and TrustRadius list no published plans and direct buyers to request a quote, though a free trial is listed on some directories.

There is a defensible reason for this. A five-page nonprofit site and a 20,000-page university portfolio spanning multiple modules are different projects, so vendors at this tier scope each deal individually rather than publish a rate card. The trade-off lands on the buyer: without a price list, you can only benchmark a quote against other quotes — which is exactly what the reported ranges above are for. In our assessment, the spread between the $15,600 average and the $150,000+ ceiling reflects module count and page volume more than anything else.

What drives a Siteimprove quote up or down?

Per public buyer reporting, four variables move a Siteimprove quote most: which modules are licensed, the number of pages and domains monitored, user seats, and contract term length (Vendr, as of August 2026).

Module bundling is the biggest lever. Buyers who license Accessibility, SEO, and Quality Assurance together reportedly receive 10–25% per-module discounts versus buying each standalone (Vendr) — a discount that only pays off if you'll actually use all three. Add-ons compound the base license: onboarding runs $2,000–$10,000+ one-time and professional services $5,000–$20,000+, while renewals carry escalators of 3–7% a year unless capped in writing. Page volume drives the rest: reported Accessibility-only pricing roughly doubles or triples between the 1,000–5,000-page and 10,000–25,000-page tiers (Vendr).

What do Siteimprove's modules actually include?

Siteimprove sells separable modules on a shared monitoring core: Accessibility (WCAG conformance scanning, guided remediation workflows, documentation support), SEO (technical SEO monitoring and keyword tracking), and Quality Assurance (broken links, spelling, and brand or legal language consistency), with analytics and governance reporting tying them together for legal, marketing, and IT stakeholders.

That breadth is the platform's genuine differentiator. Siteimprove has built its customer base substantially in higher education, government, and large multi-domain enterprises — organizations that want one governance layer, one login, and one set of reports, rather than three tools reporting to three teams. In TestParty's audits of ecommerce storefronts, we've seen the opposite problem just as often: a general-purpose governance suite frames a WCAG failure as one line item among thousands of content-quality flags, a fundamentally different job from rewriting the underlying markup. Which job you need determines whether the full suite or a single module is the right purchase — see our criteria-first comparison of 12 web accessibility tools.

What should you ask in a Siteimprove sales process?

Six questions expose the true cost and fit of a Siteimprove quote: module unbundling, page-count headroom, renewal escalators, services hours, exit terms, and detection-vs.-remediation scope.

1. Module unbundling — can we license Accessibility alone, and what do we lose by skipping SEO and Quality Assurance?
2. Page-count headroom — how many pages and domains does the contract cover, and what triggers an upgrade?
3. Renewal escalators — is the annual increase capped in writing?
4. Services hours — how many onboarding and training hours are bundled, and what do overages cost?
5. Detection vs. remediation — does the module find issues, or does someone fix them, and where do fixes land?
6. Exit terms — if we leave, do we keep our conformance reports and audit trail, or does that history live only inside the platform?

Question 5 is the one buyers most often skip. In our experience, teams that assume "accessibility platform" means "accessibility fixed" are the ones surprised that a monitoring dashboard and a remediated codebase are not the same deliverable.

Who is Siteimprove a good fit for — and who evaluates alternatives?

Siteimprove is a credible fit for large, multi-domain organizations — universities, government agencies, and enterprises running dozens of properties — that want accessibility, content quality, and SEO governed from a single platform with unified reporting. Public-sector buyers face a real compliance clock: state and local government sites fall under Title II of the ADA, and a platform documenting conformance across an entire portfolio genuinely simplifies that burden.

Evaluators look elsewhere in two situations. First, accessibility-only buyers: a team monitoring one or two domains gains little from a platform priced partly around SEO and QA modules it won't touch — the reported $8,000–$25,000 per-module add-on is real money for capability you don't need. Second, teams that want fixes landed in their own codebase, not findings in a dashboard: as of August 2026, TestParty has remediated 35 million-plus accessibility issues directly in customer source code across 100+ brands. See our seven-dimension guide to evaluating enterprise accessibility platforms and our fifteen RFP questions that expose vendor differences for the broader framework.

How does Siteimprove's pricing compare with other accessibility investment models?

Siteimprove occupies the enterprise governance-platform tier; the main alternatives are manual audit firms, overlay widgets, and source-code remediation platforms — each pricing a different unit of work.

In our assessment, the decisive question mirrors Siteimprove's own modules: are you buying detection, governance, or a fixed codebase? A governance platform coordinates reporting; an audit firm delivers a point-in-time assessment; an overlay changes what assistive technology encounters without touching the markup; source-code remediation ships the fix into your repository.

Frequently Asked Questions

How much does Siteimprove cost per year? Siteimprove does not publish pricing. Buyer-reported data as of August 2026 shows an average contract around $15,600 per year, with small single-module deployments at $15,000–$40,000, mid-sized programs at $40,000–$75,000, and large enterprise portfolios at $75,000–$150,000+ (Vendr).

What's the cost difference between the Accessibility module alone and the full suite? Reported figures put Accessibility alone at $12,000–$70,000 per year by page volume, with SEO or Quality Assurance adding $8,000–$25,000 each (Vendr, as of August 2026). Bundling all three reportedly earns a 10–25% discount — but only if you'll actually use each module.

What renewal terms do Siteimprove buyers report? Procurement data as of August 2026 reports escalators of 3–7% on renewals and discounts of 10–25% for multi-year commitments (Vendr). Cap the escalator before signing, and price professional-services hours separately — those add-ons run $5,000–$20,000+.

Is quote-based pricing a red flag? No. Custom quotes are standard at this tier because scope genuinely varies by module count and page volume. The risk is information asymmetry — without a rate card, buyers can only benchmark a quote against other quotes. Use the ranges above as calibration and ask every vendor to itemize modules and escalators separately.

How does Siteimprove's pricing model compare with source-code remediation? They price different outcomes. Siteimprove's reported contracts price a governance platform — monitoring, reporting, and workflow tools across accessibility, SEO, and content quality (Vendr, as of August 2026). Source-code remediation prices fixing the underlying code itself; published one-time ecommerce projects list at $15,000–$50,000+ (Connect Media Agency, 2026), while TestParty offers a free scanner app with remediation scoped per store.
