The Technical SEO Audit Checklist for B2B Sites

Most B2B technical SEO audits produce a 60-page report that nobody acts on. The findings are real, but they arrive unprioritised, drowned in severity labels, and disconnected from the pages that actually drive revenue. The result is a document that gets filed and a site that stays broken.

This is a working checklist, not a report template. It runs in sequence, starts with the issues most likely to be costing you rankings, and focuses on the commercial pages that matter in B2B. Work through it in order. Each step tells you what to check, why it matters, and what good looks like. It pairs with our wider B2B SEO guide , which covers the strategy this audit supports.

Before you start

You need three things: Google Search Console access, a crawler (Screaming Frog or similar), and PageSpeed Insights. You also need a clear list of your commercial pages — service pages, high-intent landing pages, and your best-converting content. Technical issues on those pages cost more than issues on a forgotten blog post, so weight your effort accordingly.

The technical SEO audit checklist

Complete these eight steps in order. Earlier steps surface the issues that most directly affect whether your pages can rank at all; later steps refine performance once the foundations are sound.

Step 1: Confirm your pages are indexable

Open the Pages report in Google Search Console and review what is and is not indexed. Look for two failure modes. First, commercial pages that should rank but are excluded — blocked by robots.txt, carrying a noindex tag, or missing from the sitemap. Second, low-value pages that should not be indexed but are — thank-you pages, internal search results, parameter URLs, staging pages.

Good looks like: every revenue page indexed, every junk page excluded, and the indexed count roughly matching your real page count. A bloated index dilutes authority.

Step 2: Check your robots.txt and sitemap

Read your robots.txt line by line. A single overzealous disallow rule can block an entire section. Then open your XML sitemap and confirm it lists only canonical, indexable, 200-status URLs — no redirects, no 404s, no noindex pages. Submit it in Search Console and check for errors.

Good looks like: robots.txt blocks only what it should, and the sitemap is a clean list of pages you actually want ranked.

Step 3: Crawl the site and find broken links and redirects

Run a full crawl. Hunt for 404 errors on internal links, redirect chains (one redirect pointing to another), and redirect loops. Broken internal links waste crawl budget and leak authority; long redirect chains slow pages and dilute link equity.

Good looks like: no internal 404s, every redirect resolves in a single hop to a 200 page, and no loops.

Step 4: Audit canonical tags and duplicate content

For each important page, confirm the canonical tag points to itself unless it deliberately consolidates duplicates. Look for unintended duplication — HTTP and HTTPS versions, trailing-slash variants, www and non-www, parameter URLs serving the same content. Each duplicate splits ranking signals.

Good looks like: one canonical version of every page, with all variants redirecting or canonicalising to it.

Step 5: Review titles, meta descriptions and headings

Crawl for missing, duplicated or truncated title tags and meta descriptions, focusing first on commercial pages. Confirm each page has one H1 that reflects its primary query and a logical H2 to H3 hierarchy beneath it. Titles and descriptions are both a ranking signal and your click-through pitch in the results page.

Good looks like: unique, intent-matched titles and descriptions on every commercial page, and a single clear H1 per page.

Step 6: Test Core Web Vitals on your money pages

Run PageSpeed Insights on your service and high-intent landing pages, not just the homepage. Check Largest Contentful Paint, Cumulative Layout Shift and Interaction to Next Paint against Google's thresholds. Heavy CMS templates and unoptimised hero images are the usual culprits on B2B sites.

Good looks like: all three Core Web Vitals in the green band on the pages that drive pipeline. Slow commercial pages cost both rankings and conversions, a link explored in our piece on the conversion rate maths B2B marketers ignore .

Step 7: Validate structured data and mobile rendering

Use Google's Rich Results Test on pages where schema applies — articles, FAQs, services. Confirm the markup is valid and matches the visible content. Then check mobile rendering: Google indexes mobile-first, so a page that breaks or hides content on a phone is the page Google judges. Test real devices, not just a resized browser.

Good looks like: valid, accurate structured data and a mobile experience equal to desktop in content and usability.

Step 8: Map and strengthen internal linking

Crawl your internal link structure and check that high-intent commercial pages receive links from related content, using descriptive anchor text. B2B sites routinely orphan their best pages, leaving authority stranded on the homepage. Internal links are also how topical clusters signal relevance to search engines.

Good looks like: every commercial page linked from relevant content, sensible anchor text throughout, and clusters interlinked. The cluster method itself is covered in building B2B topic clusters that rank .

Turn findings into a prioritised plan

An audit is worthless until it becomes a sequenced list of fixes. Sort everything you found by two axes: impact on commercial pages and effort to fix. Tackle high-impact, low-effort items first — broken links on service pages, missing titles, an over-broad robots rule. Schedule high-impact, high-effort work — a page-speed overhaul, a site migration cleanup — as projects. Park low-impact items unless they are trivial.

Make it a routine, not an event

Technical health degrades. New pages ship with errors, plugins change, redirects accumulate, and Search Console flags new issues. Run a light version of this checklist monthly on your commercial pages and a full audit quarterly. The compounding value of B2B SEO depends on a technically sound foundation, which is why this audit underpins the strategy in our B2B SEO strategy guide .
