Technical SEO Audit: A 200-Factor Checklist for B2B Websites

A technical SEO audit is not a list of things to fix. It’s a diagnostic that establishes what Google can and cannot understand about your website — and why your organic performance is what it is. For B2B companies, where the difference between ranking #3 and #8 for a commercial term can mean hundreds of thousands of dollars in pipeline, getting this right is not optional.

This guide covers the key areas of a technical SEO audit, organized by priority. Not every issue is equal — a crawlability problem blocks everything downstream, while a missing meta description is cosmetic.

Priority 1: Crawlability and Indexation

Before anything else, Google must be able to discover and crawl your pages. Common crawlability failures in B2B websites:

• Robots.txt blocking key sections — Check that no important directories or URL patterns are blocked. This is more common than expected, especially after migrations or CMS changes.
• Noindex tags on live pages — Service pages, landing pages, or blog posts accidentally set to noindex. Always verify in Google Search Console.
• Orphan pages — Pages with no internal links pointing to them. Google may discover these through sitemaps but will assign them minimal authority.
• Sitemap accuracy — Sitemaps should only include indexable, canonical URLs. Including redirected, noindexed, or 404 URLs signals poor site hygiene.

Priority 2: Core Web Vitals

Google’s Page Experience signals are now direct ranking factors. The three Core Web Vitals thresholds:

• Largest Contentful Paint (LCP) — Under 2.5s is “Good.” Over 4s is “Poor.” For B2B sites, the LCP element is typically a hero image or H1. Optimize by preloading the LCP element, serving images in WebP format, and eliminating render-blocking resources.
• Interaction to Next Paint (INP) — Under 200ms is “Good.” This replaced First Input Delay in March 2024. Long JavaScript tasks during scroll and click events are the primary cause of INP failures.
• Cumulative Layout Shift (CLS) — Under 0.1 is “Good.” Common B2B site CLS causes: lazy-loaded images without explicit dimensions, injected chat widgets, and font swap without size-adjust.

Measure CWV using PageSpeed Insights (field data from the CrUX dataset, not just lab scores) and verify against Google Search Console’s Core Web Vitals report, which shows real-user data segmented by page group.

Priority 3: Site Architecture

For B2B sites, architecture failures are usually about crawl depth and internal link equity distribution:

• Click depth over 3 — Pages more than 3 clicks from the homepage receive proportionally less crawl equity. If your core service pages are buried in navigation, they’ll rank below their true potential.
• Flat architecture for key pages — Homepage → Service category → Individual service is the correct depth for commercial pages. Blog posts can be deeper.
• Internal link anchor text — Links to commercial pages should use keyword-rich anchor text, not generic “click here” or “learn more.” This is how you pass topical relevance through the site.
• Orphaned content clusters — Blog posts in a cluster should link to each other and to the relevant commercial page. If your “B2B content marketing” article doesn’t link to your content marketing service page, you’re leaving commercial signal on the table.

Priority 4: Schema Markup

Schema markup tells Google what your content means, not just what it says. For B2B websites, the minimum viable schema set is:

• Organization — Name, URL, logo, contact info, social profiles, and sameAs links to all brand properties
• WebSite — With SearchAction for sitelinks search box
• Service — On each service page: service name, description, provider (Organization), area served, service type
• Article — On blog posts: headline, author (with Person schema), datePublished, dateModified, image
• Person — For founders and authors: name, jobTitle, affiliation, sameAs links to LinkedIn and other authority profiles
• FAQPage — On pages with FAQ sections, to qualify for FAQ rich results
• BreadcrumbList — On all pages except the homepage

Priority 5: Duplicate Content and Canonicalization

B2B CMS platforms (WordPress, HubSpot, Webflow) all produce duplicate content by default if not configured correctly:

• Category and tag archive pages — These often duplicate blog post content. Either noindex them or ensure they have unique editorial value.
• Paginated archives — /page/2/, /page/3/ etc. should be self-referencing canonicals, not rel=next/prev (Google dropped support for pagination signals in 2019).
• Parameter URLs — Sort, filter, and session parameters generate near-duplicate pages. Canonicalize or disallow in robots.txt.
• HTTP vs HTTPS, www vs non-www — All variants should 301-redirect to a single canonical URL. A 200 response on http://yourdomain.com is a duplicate content signal.

Priority 6: Mobile Usability and Structured Data Errors

Google uses mobile-first indexing for all sites. Mobile usability issues that affect B2B sites:

• Text too small to read (below 12px base font)
• Clickable elements too close together (minimum 48px touch target recommended)
• Viewport not configured (meta viewport tag missing)
• Content wider than screen (horizontal scroll on mobile)

Structured data errors — invalid @type values, missing required properties, or malformed JSON-LD — suppress rich results and can trigger manual actions in extreme cases. Validate all schema using Google’s Rich Results Test.

The Audit Deliverable

A proper technical SEO audit is not a spreadsheet of Screaming Frog errors. It’s a prioritized action plan that distinguishes between issues that block performance and issues that are cosmetic. For most B2B websites, the top 10 prioritized issues will account for 80% of the organic performance gap versus competitors.
