Free SEO audit tool for any B2B website

Your website is often the first thing a potential customer sees. If it is slow, hard to find on Google, or looks outdated on a phone, you are losing deals before a conversation even starts. This free SEO audit grades every page on your site against 50 plus checks across SEO, accessibility, performance, security, content quality, and business readiness, then returns a 30 page PDF report with prioritized fixes.

No credit card. No paid plan. Just enter your URL above.

What this SEO audit checks: 50+ checks across 6 categories

The audit grades your site against six categories. Together they decide the overall score from 0 to 100. The first five categories are weighted; Business Intelligence is reported separately as supplemental insight.

SEO (30% of score)

Meta titles and descriptions, H1 tags, canonical tags, Open Graph and Twitter Card metadata, schema.org structured data validation, internal and external link analysis, keyword cannibalization detection, content readability score, content word count analysis, keywords in URL check, header tags analysis, and sitewide duplicate title, description, and content detection. This is the SEO audit you would expect from any free tool, run across every page on the site rather than just the homepage.

Accessibility and WCAG 2.1 compliance (25% of score)

WCAG 2.1 Level A and AA criterion-by-criterion grading: Non-text Content, Info and Relationships, Contrast (Minimum), Resize Text, Keyboard, Bypass Blocks, Link Purpose, Focus Visible, Language of Page, Labels or Instructions, Parsing, and Name Role Value. Plus color contrast at WCAG AA, image alt text quality, ARIA validation, focus management, form labels, and link accessibility.

The audit then maps your failing criteria to legal risk under three frameworks: ADA Title II, Section 508, and the European Accessibility Act. Each gets a risk score (none, medium, high) and the applicable deadline. For B2B companies in regulated industries, public-sector contractors, or anyone selling into the EU, this is the most expensive section of the report to ignore.

Performance (25% of score)

Core Web Vitals: Largest Contentful Paint (LCP), Cumulative Layout Shift (CLS), First Contentful Paint (FCP), and Time to First Byte (TTFB). Plus average page load time, average page size, content compression check, caching headers validation, image performance analysis (compression and modern formats), code minification, and HTTP/2 protocol support. Slow sites lose mobile visitors and rank lower; this section tells you exactly where the time goes.

Content Quality (10% of score)

Content readability score (Flesch-Kincaid or similar), content word count analysis, content freshness detection (when each page was last updated), and spelling and grammar check across the site. Thin or stale content is a common reason B2B pages stall in search.

Security (10% of score)

SSL certificate expiration check, security headers (Content-Security-Policy, X-Content-Type-Options, X-Frame-Options, Referrer-Policy, Permissions-Policy), subresource integrity (SRI) on third-party scripts, cookie and privacy compliance (GDPR, CCPA), CORS configuration, PII and exposed-data detection, and a full site cookie inventory. Security gaps damage trust before a prospect even reads the homepage and are increasingly a procurement gate in enterprise sales.

Business Intelligence (supplemental)

Marketing technology stack detection (analytics, CRM, marketing automation), lead capture infrastructure scoring, trust signals and social proof analysis (testimonials, certifications, client logos), business profile signals (team size, industry focus), pricing page analysis (tier structure, transparency, trust elements), content authority and thought leadership, and CTA analysis (variety, placement, primary vs secondary). Not weighted in the overall score, but the section most B2B leadership teams find immediately actionable.

Plus site-level checks

Domain expiration check, robots.txt validation, sitemap detection and validation, HTTPS redirect check, web server info, orphan page detection (pages with no inbound links), a broken-links inventory with the specific URLs that need fixing, URLs not in your sitemap, redirect chain detection, sitewide duplicate content detection, and a worst-performing pages list with per-page scores.

Most free SEO audit tools focus on technical SEO and ignore accessibility. This one treats accessibility as a board-level concern, because for B2B companies it is.

The audit grades your site against WCAG 2.1 Level A and AA criterion by criterion. Pass, partial, or fail status for each, with severity and the on-page test that produced the result. Then the report maps your specific failures to three legal frameworks:

  • ADA Title II (U.S. state and local government websites, WCAG 2.1 AA): risk level, failing criteria, applicable deadline.
  • Section 508 (U.S. federal agency and contractor websites, WCAG 2.0 AA): risk level, failing criteria, currently in effect.
  • European Accessibility Act (products and services sold in the EU, WCAG 2.1 AA): risk level, failing criteria, June 28 2025 deadline.

If you sell to the public sector, do business in the EU, or operate in a regulated industry, this section turns a checklist into a defensible position. If you do not, the WCAG grading is still the fastest way to surface usability problems that frustrate real customers, including the ones using your site on a phone in poor light or with a screen reader.

Automated testing covers approximately 30 to 40 percent of WCAG 2.1 criteria. The report flags this clearly and recommends manual review for full compliance certainty.

What is in your SEO audit report?

The 30-page PDF report is what you actually receive. Designed to be opened by leadership, forwarded to a developer, or attached to an agency brief.

  • Cover page with your domain, audit date, and overall score (0 to 100) plus the six category scores.
  • Executive Summary with category breakdown bar chart, top priority issues, total pages crawled, total errors, total warnings, total passing checks, and average load time.
  • Audit Metrics including pages crawled, errors, warnings, failed pages count, and Core Web Vitals (LCP, CLS, FCP, TTFB).
  • Accessibility and WCAG 2.1 compliance summary with Level A and AA passing counts, legal risk per framework, and the failing criterion table.
  • Priority Fixes section ranked by severity times page traffic, so you can act on the issues that affect the most visitors first.
  • Issues Requiring Attention grouped by category: Technical, Accessibility, On-Page, Security, Performance, Business. Each issue includes error count, affected URLs, and a recommended fix.
  • Business Intelligence section with scores for marketing tech stack detection, lead capture, trust signals, pricing transparency, content authority, and CTA analysis.
  • Site-level checks covering pre-crawl checks (robots.txt, SSL, domain expiration, sitemap) and post-crawl checks (duplicate H1, title, description, content; keyword cannibalization; orphan pages; broken links; non-indexable URLs; site cookie inventory).
  • Worst-Performing Pages list with per-page scores and the specific issues each page needs.
  • Passing Checks so you can see what is already working.

The report is yours to keep. Share it with leadership, archive it as a quarterly benchmark, or send it to your developers as a punch list.

How does the SEO audit work?

  1. Enter your website URL in the form above.

No credit card. No paid tier. No sales call before you see results.

What is a B2B SEO audit and how is it different?

A B2B SEO audit weighs accessibility legal risk, security signals, content authority, and trust signals more heavily than a typical consumer-site audit. The reasons:

  • Long sales cycles: a prospect may visit your site five times across six months before a conversation. Every visit reinforces or erodes trust. A slow, broken, or visibly outdated site loses deals during the research phase, not the close.
  • Regulated industries: life sciences, financial services, government contracting, healthcare, legal, and education face accessibility, privacy, and security requirements with real legal exposure. WCAG legal-risk scoring matters here.
  • Technical decision-makers: B2B prospects often include engineers, IT leads, and operations stakeholders who inspect headers, certificates, page weight, and schema. A site that fails their checks fails their procurement reviews.
  • Smaller marketing teams: most B2B marketing teams are 1 to 5 people and do not have a dedicated technical SEO. They need an audit that prioritizes fixes, not a 500-row CSV that nobody reads.

This audit was built around those constraints. The Business Intelligence section, the WCAG legal-risk mapping, and the priority-fixes ranking exist because most B2B websites are not failing on Google, they are failing on stakeholder confidence.

AI search engines (ChatGPT, Perplexity, Gemini, Claude) are an increasing share of B2B research. They cite content based on similar but not identical signals to classic search.

The audit covers the foundations that AI search depends on:

  • Schema.org structured data validation so AI assistants can parse your entity, services, and content correctly.
  • Content authority and thought leadership scoring since AI assistants prefer content that demonstrates expertise and attribution.
  • Content quality (readability, freshness, word count) which affects how AI systems summarize and cite your pages.
  • Open Graph and Twitter Card metadata which AI systems and modern search results use to render snippets.
  • Mobile experience since most AI search front-ends are mobile-first.
  • Site structure: canonical tags, sitemap presence, orphan pages, internal linking density.

There is no separate AI-only check in the audit. There does not need to be. The same technical and content signals that drive classic search also drive AI search; the audit reports on those signals in one place.

Why this matters for B2B companies

For companies in manufacturing, life sciences, construction, financial services, and professional services, your website does more than look nice. It is where prospects validate you after a referral, a LinkedIn message, or a trade show conversation. What we see when we audit B2B websites:

  • Most mid-market B2B sites fail at least one WCAG AA criterion, which is a legal exposure under ADA Title II and the European Accessibility Act.
  • Many regulated-industry sites have security gaps (missing CSP headers, expired or near-expiring SSL, third-party scripts without subresource integrity) that hurt trust before a prospect reads the homepage.
  • Slow page speed is not just a frustration. Google pushes slow sites lower in search results and AI assistants deprioritize them as citation sources.
  • Schema.org is often missing or invalid on B2B sites that need to be cited by AI search.

A single enterprise deal can be worth tens of thousands of dollars or more. If your website turns away even one qualified prospect per quarter, the cost of inaction dwarfs the cost of fixing it.

How often should you run an SEO audit?

Quarterly at minimum. Plus after every significant change: a redesign, rebrand, CMS migration, framework upgrade, major content overhaul, new product launch, or any change to your hosting, DNS, or CDN. During active SEO work, many B2B teams audit monthly; once stabilized, quarterly is the right cadence.

The audit is fast enough to run before every deploy if you want to catch regressions early. A new canonical tag pointing the wrong way, a slipped Core Web Vital after a tag-manager change, a freshly broken sitemap, or an expired certificate all show up immediately.

Free SEO audit vs paid SEO audit

A free SEO audit, including this one, is broad and automated. It surfaces the issues that automated tools can detect: technical signals, on-page elements, performance metrics, accessibility criteria that have machine-checkable answers, security headers, and the like. That covers roughly 70 percent of what an audit should produce.

A paid SEO audit from an agency or consultant adds the parts a tool cannot do alone: manual review of WCAG criteria that require human judgement, content gap analysis against competitor SERPs, backlink profile review, log-file analysis for crawl-budget waste on large sites, internal link audit with intent mapping, and the strategic prioritization that ties findings to revenue.

Most B2B companies should start with this free audit, then engage a paid audit only if the free audit surfaces enough issues to justify the deeper work. If you want help acting on the findings, Axiolo’s SEO team takes audits like this one and turns them into a delivery plan.

What to do after your audit

Found problems? Good. Now you have a prioritized list of what to fix.

Start with the highest-priority issues in your report. These are usually expired or near-expired SSL certificates, accessibility failures that create legal risk, broken pages and broken links, missing or invalid schema markup, and Core Web Vitals failures that search engines actively penalize.

Want help executing? Axiolo works with B2B companies to turn audit findings into a digital presence that generates leads. We fix the technical problems, build the content that attracts your ideal customers, and make sure your website works as hard as your sales team does. Let’s talk about your results.

Frequently Asked Questions

What is an SEO audit and why do B2B companies need one?

An SEO audit grades how well a website is set up to be found, understood, and trusted by search engines and the people they send. For B2B companies, an audit also doubles as a website health check: it surfaces accessibility legal risk, security gaps, performance issues, and trust signals that affect whether a prospect believes your site enough to take the next step. Without one, problems compound silently for months before anyone notices the lead drop.

What does this SEO audit check?

The audit grades your site across six categories: SEO (meta tags, schema, canonical, headers, duplicate detection, keyword cannibalization), Accessibility and WCAG 2.1 compliance (color contrast, alt text, ARIA, focus management, plus legal risk under ADA Title II, Section 508, and the European Accessibility Act), Performance (Core Web Vitals, load time, page size, compression, caching, image optimization), Content Quality (readability, freshness, word count, spelling), Security (SSL, security headers, GDPR/CCPA cookie compliance, PII exposure, CORS), and Business Intelligence (lead capture, trust signals, pricing transparency, CTA diversity, marketing tech stack). 50+ individual checks in total.

Does the audit check WCAG accessibility compliance for ADA, Section 508, or the European Accessibility Act?

Yes. The audit grades your site against WCAG 2.1 Level A and AA criterion by criterion, then maps failures to legal risk under ADA Title II (U.S. state and local government sites), Section 508 (U.S. federal contractors), and the European Accessibility Act (products and services sold in the EU). For each framework you receive a legal-risk score, the failing criteria, and the applicable compliance deadline. Few free audit tools surface this, and it matters most for B2B companies in regulated industries or selling to the public sector.

What is included in the 30-page PDF SEO audit report?

The PDF includes: a cover page with overall score and category breakdown, executive summary with top priority issues, audit metrics (pages crawled, errors, warnings, passing checks, average load time), Core Web Vitals snapshot (LCP, CLS, FCP, TTFB), accessibility and WCAG 2.1 compliance summary, priority fixes ranked by severity times traffic, full issues list grouped by category, site-level checks (SSL, domain, robots.txt, sitemap, orphan pages, broken links), worst-performing pages with per-page scores, and a list of passing checks. Designed to be shared with leadership or used to brief a developer or agency.

Does the audit check schema markup and AI search readiness?

Yes. The audit validates schema.org structured data, Open Graph and Twitter Card metadata, content authority and thought-leadership signals, content quality (readability, freshness, word count), and mobile experience. These are the same signals that AI search engines like ChatGPT, Perplexity, Gemini, and Claude use to evaluate and cite content. There is no separate AI-only check; the audit covers the underlying technical and content signals that drive both classic and AI search visibility.

How is this different from paid tools like Ahrefs, SEMrush, or Screaming Frog?

Ahrefs and SEMrush are excellent at backlink, keyword, and rank tracking, but their site audits are technical-SEO focused. Screaming Frog is a desktop crawler that requires expertise to interpret. This audit is built for B2B decision makers who want one report that combines SEO, accessibility legal risk, performance, security, and business-readiness signals (lead capture, trust signals, CTA quality) without paying a per-seat subscription. Use the paid tools for deep ongoing work and this one for fast, broad assessments and stakeholder-ready PDFs.

Can the audit run on a staging site or password-protected site?

The audit requires a publicly reachable URL. If your site is behind a login, IP allowlist, or basic auth, the crawler cannot complete the analysis. For pre-launch or staging audits, contact the Axiolo team and we can arrange a manual review instead.

How long does the audit take?

Under 60 seconds for most B2B sites. Enter your URL and the audit crawls every reachable page, runs the 50+ checks, and produces the report. For larger sites the crawl may take a few minutes; you will see a live progress indicator while it runs and the PDF download as soon as the audit completes.

Is this really free?

Free, no credit card, no paid plan. We collect your email so we can send the report and contact details so we can follow up if you want help acting on the findings. No surprise upsell, no card-on-file, no usage limit.

How accurate is the data?

The audit uses the same signals that search engines, accessibility tools, and AI assistants use to evaluate sites. WCAG grading covers roughly 30 to 40 percent of criteria automatically; the rest require manual review for full legal certainty. Core Web Vitals are measured against Google's published thresholds. Schema.org validation uses the official vocabulary. Manual review is always recommended for high-stakes compliance, but the automated audit reliably identifies the highest-impact issues.

Can I download the results?

Yes. The audit produces a 30-page PDF report you can download immediately, share with your leadership team, send to your developers, use to justify a website investment, or keep as a benchmark to track quarterly improvement.

What should I do after getting my results?

Start with the priority fixes section of the report, which ranks issues by severity times page traffic. Most B2B sites should triage in this order: critical security and SSL issues, accessibility legal risk if you are subject to ADA or EAA, broken pages and broken links, duplicate titles or meta descriptions, missing schema markup, and Core Web Vitals. If you want help turning the findings into a delivery plan, Axiolo works with B2B companies to fix the technical problems and build a digital presence that generates leads.

Do I need to be technical to understand the report?

No. Each finding includes a plain-language explanation of why it matters to your business and a recommendation for how to fix it. The report is built for business owners and executives as well as IT teams. The priority fixes section is sortable by traffic impact so non-technical readers can see what to fix first.

How often should I run an SEO audit?

Quarterly at minimum, plus after every significant change: a redesign, rebrand, CMS migration, framework upgrade, content overhaul, or new product launch. Regular audits catch silent regressions (a broken canonical tag, a slipped Core Web Vital, an expired certificate, a new accessibility failure) before they cost you visibility or leads. Many B2B teams run the audit monthly during active SEO work and quarterly thereafter as a maintenance check.

Does the audit work for non-English websites?

Yes. The audit checks technical signals (Core Web Vitals, schema, security, accessibility, performance) that are language-agnostic. Content-quality checks (readability, spelling, word count) currently optimize best for English-language content. Multilingual sites with hreflang configured are audited correctly; each language version is treated as part of the crawl.

Can this tool simulate Googlebot behavior?

Yes for crawl-related checks: the audit follows the same rules Googlebot does (robots.txt directives, canonical signals, noindex, hreflang). The accessibility and performance checks use the same Lighthouse-style measurements Google uses to rank Core Web Vitals.
