The Manufacturing SEO Audit: 40 Buyer-Visibility Checks

This is the same structure we use when auditing a manufacturer's site before recommending any content or keyword strategy. Work through it in order; the early sections (technical, indexation) can block or undermine everything after them.

Technical SEO (1-4)

1. Confirm the site serves HTTPS on every page with no mixed-content warnings.
2. Check that there is one canonical version of every URL (no duplicate http/https or www/non-www variants both live).
3. Verify robots.txt isn't accidentally blocking capability pages or important directories.
4. Confirm XML sitemap exists, is submitted in Search Console, and only lists indexable, canonical URLs.

Indexation (5-8)

1. In Search Console's Page Indexing report, check how many capability pages are marked "Discovered, not indexed" or "Crawled, not indexed."
2. Confirm your most important capability pages are indexed and appear when searched by exact URL.
3. Check for accidental noindex tags on live pages, especially after CMS migrations.
4. Review crawl stats for spikes in 404s or server errors that could be limiting crawl budget on a large site.

Architecture (9-12)

1. Confirm the site has a clear hub-and-spoke structure connecting a core capability hub to industry, material, and certification-specific pages (see how to build a manufacturing topic cluster that wins RFQs).
2. Check that no important page is more than 3-4 clicks from the homepage.
3. Confirm URL structure is logical and readable (e.g. /capabilities/cnc-machining/aerospace), not parameter-heavy or auto-generated.
4. Look for orphaned pages with no internal links pointing to them at all.

Internal links (13-16)

1. Confirm every capability page is linked from the homepage or a top-level navigation menu.
2. Check that blog posts link into relevant capability pages with varied anchor text, not repeated exact phrases.
3. Confirm high-value pages receive more internal links than low-priority ones (link equity should roughly match business priority).
4. Review for broken internal links using a crawler tool.

Capability pages (17-19)

1. Confirm each capability page names specific processes, materials, part types, and certifications rather than describing services abstractly.
2. Check that capability pages include a clear RFQ or quote request path, not just a general contact form.
3. Confirm capability pages are updated when equipment, materials, or certifications change; stale capability lists undermine buyer trust as much as search visibility.

Metadata (20-22)

1. Check that every indexable page has a unique title tag under roughly 60 characters that reflects the specific page content.
2. Confirm meta descriptions are unique, under roughly 155 characters, and describe the actual page rather than generic boilerplate.
3. Verify heading structure uses one H1 per page with a logical H2/H3 hierarchy beneath it.

Structured data (23-25)

1. Implement Organization schema with accurate name, logo, and certifications where applicable.
2. Add Product or Service schema on capability pages where appropriate, following Google's structured data guidelines.
3. Validate all structured data with Google's Rich Results Test to confirm no errors block eligibility for enhanced search appearance.

Images (26-27)

1. Confirm every meaningful image (shop floor, parts, certifications) has descriptive, non-keyword-stuffed alt text.
2. Check that images are compressed and served in modern formats to avoid unnecessary page weight.

Core Web Vitals (28-30)

1. Check Largest Contentful Paint, Interaction to Next Paint, and Cumulative Layout Shift scores in PageSpeed Insights or Search Console's Core Web Vitals report.
2. Identify whether failing scores concentrate on specific templates (e.g. capability pages with heavy image galleries) versus site-wide.
3. Confirm fixes target the actual bottleneck (render-blocking scripts, unoptimized images, server response time) rather than guessing.

Mobile UX (31-32)

1. Test capability pages and RFQ forms on an actual mobile device, not just a browser resize, checking tap target size and form usability.
2. Confirm Google is indexing the mobile version of your pages correctly, consistent with Google's mobile-first indexing documentation.

Content quality (33-34)

1. Review whether capability page content matches the depth and specificity a buyer with a real spec would need, rather than restating generic service descriptions (see why generic manufacturing keywords bring traffic, not RFQs).
2. Check for outdated statistics, discontinued certifications, or old equipment lists still referenced on live pages.

Authorship (35)

1. Confirm technical and process-heavy content is attributed to a named person with relevant operational experience where possible, supporting the kind of expertise signals described in Google's guidance on E-E-A-T.

Citations (36)

1. Check that any factual or regulatory claim (certifications, standards, government program references) links to the issuing body or an authoritative source rather than an unsupported statistic.

Local relevance (37-38)

1. Confirm location-specific pages (if any) reflect a genuinely served area, with accurate address and service radius information, not a generic city name inserted for search volume.
2. Verify Google Business Profile details (address, categories, hours) match the website exactly.

Conversion (39-40)

1. Confirm every capability and industry page has a clear, specific call to action, not a generic "Contact Us" link.
2. Check that RFQ form submissions are tracked back to the landing page and query that generated them, so future SEO and keyword decisions can be based on real conversion data rather than traffic volume alone.

How to use this list

Don't try to fix all 40 items in one pass. Work top to bottom: technical and indexation issues first, since they can suppress everything below them regardless of how good your content is. Architecture and internal linking come next, since they determine whether Google's crawlers and your buyers can actually find your best pages. Content, structured data, and conversion checks matter most once the structural foundation is sound.
