Different Products for Different Scales

This comparison is between a focused accessibility tool and a comprehensive website quality platform. That distinction matters because it explains both the price gap and the feature gap.

A11yProof does one thing: scan your site for WCAG violations and generate AI-powered code fix suggestions. It is built for SMBs and agencies that need accessibility compliance without paying for a full analytics suite.

Siteimprove does many things: accessibility scanning, SEO analysis, content quality scoring, broken link detection, and policy compliance monitoring. It is built for mid-market and enterprise organizations that want a single platform for website quality management.

The Price Difference

A11yProof starts at $29/month. Siteimprove starts at $500+/month with annual contracts. That is a 17x price difference at the entry level.

For 25 sites, A11yProof’s Agency plan costs $199/month. Siteimprove’s equivalent would be custom-priced but typically runs $2,000+/month. At scale, the difference grows.

The question is whether the extra $470+/month buys capabilities you need. If you use Siteimprove for SEO analysis, content quality scoring, and accessibility together, the bundled pricing may make sense. If you only need accessibility, you are paying enterprise prices for a single module.

Fix Generation vs Issue Reporting

This is where A11yProof adds value that Siteimprove does not offer. Both tools scan for WCAG violations. Both generate reports showing what is wrong. But A11yProof goes further by generating AI-powered code fix suggestions for each violation.

Instead of a report that says “Image missing alt text on line 47,” A11yProof shows you the specific HTML change to make. This reduces the time between identifying an issue and resolving it, especially for teams without deep accessibility expertise.

Siteimprove provides documentation about the relevant WCAG criteria and general guidance on remediation, but the actual fix implementation is left entirely to your development team.

Who Should Choose What

Choose A11yProof if: you need accessibility scanning and fix suggestions without paying for a full website quality suite, you want month-to-month pricing, and you have developer resources to apply code fixes.

Choose Siteimprove if: your organization needs a comprehensive website quality platform, you have the budget for $500+/month, and you want SEO, content quality, and accessibility analysis in a single tool.

Neither option feel right?

Most small businesses pay for accessibility features they don't need. A11yProof starts at from $29/month.

Verdict

A11yProof wins on price and AI-powered fix generation. Siteimprove is a comprehensive website quality platform but costs 5-10x more and bundles features many SMBs do not need. For organizations that only need accessibility scanning and remediation, A11yProof delivers the core value at a fraction of the price.

Q&A

Is Siteimprove overkill for a small business?

For most SMBs, yes. Siteimprove bundles accessibility, SEO, content quality, and policy compliance into a single platform starting at $500+/month. If you only need accessibility scanning and fix guidance, you are paying 5-10x what a focused tool like A11yProof costs for capabilities you will not use.

Q&A

Does A11yProof match Siteimprove on accessibility scanning?

For WCAG 2.1 AA automated testing, A11yProof's AI scanner covers the same criteria Siteimprove tests. Siteimprove offers AAA-level scanning and more detailed organizational reporting. Where A11yProof exceeds Siteimprove is in AI-generated code fix suggestions. Siteimprove identifies issues but leaves the fix implementation entirely to your team.

Q&A

Which tool is better for an agency managing multiple client sites?

A11yProof's Agency plan covers 25 sites for $199/month. Siteimprove's multi-site pricing is custom but typically runs $2,000+/month. For agencies, A11yProof is 10x more cost-effective with comparable automated accessibility scanning.

What does Siteimprove include that A11yProof does not?
Siteimprove is a full website quality platform that includes accessibility testing, SEO analysis, content quality scoring, policy compliance, and broken link monitoring. A11yProof focuses specifically on accessibility scanning and code-level fix generation. If you need the broader website quality features, Siteimprove covers more ground. If you only need accessibility compliance, you are paying for capabilities you will not use.
Is Siteimprove worth 5-10x the price of A11yProof?
It depends on what you need. If your organization requires a comprehensive website quality platform with accessibility as one component, Siteimprove's bundled approach may justify the price. If you need accessibility scanning and fix suggestions specifically, A11yProof delivers that at $29-$199/month versus $500+/month.
Does Siteimprove generate code fixes like A11yProof?
Siteimprove identifies accessibility issues and provides remediation guidance, but it does not generate AI-powered code fix suggestions. You get reports showing what is wrong and documentation about the relevant WCAG criteria. A11yProof goes a step further by generating specific code changes you can apply to resolve each issue.
Can a small business justify Siteimprove's pricing?
Siteimprove is designed for mid-market to enterprise organizations. At $500+/month with annual contracts, it is priced for teams with dedicated web quality budgets. Most SMBs with 1-5 sites would be better served by a focused accessibility tool at a lower price point.
