Run an on-page SEO audit before a B2B site redesign

A redesign can make a B2B website easier to use and maintain. It can also erase useful search signals if the team changes page addresses, removes content or overlooks technical problems. An on-page SEO audit before the redesign gives marketing managers a baseline and a checklist for protecting organic traffic during the site migration.

The aim is not to preserve every page exactly as it is. It is to understand what each important page does, decide what should change and carry the right signals into the new site. Start before design and development are locked in.

1. Record the current baseline

Build a list of current URLs, then identify which pages matter to the business. Include service pages, industry pages, resource content and pages that generate enquiries. Use the search and website performance data available to your team to note organic visits, impressions, enquiries and relevant search queries. Record the date range and source so that later comparisons use the same basis.

Do not use traffic alone to decide what stays. A page with modest visits may attract high-intent buyers or support a sales conversation. Ask sales and subject-matter teams which pages prospects use, and check whether a page has backlinks or a role in the conversion path. Flag pages with unclear value for review rather than deleting them on sight.

The Marketing Specialists offers a free online SEO audit tool. It can be one starting point for an audit, but a tool's output should not replace your own page inventory, business context or review of search performance.

2. Check technical and on-page errors

For each priority URL, review whether the page can be reached, loads the intended content and is eligible to appear in search. Check for accidental blocking, incorrect indexing instructions, broken links, missing or duplicated page titles, weak headings, and canonical signals that point somewhere unexpected. Note errors separately from planned changes. That distinction helps the redesign team avoid carrying a known problem into the new site.

Inspect important templates as well as individual pages. A shared template issue can affect dozens of URLs. Check that headings describe the page, images have useful alternative text where needed, and internal links point to relevant destinations. Review mobile layouts and page speed as user and technical concerns, but do not treat a single audit score as a ranking forecast.

For every finding, write down the URL, the issue, its likely consequence, the recommended action and who owns it. Prioritise errors that make key pages unavailable or confusing before cosmetic improvements.

3. Find content gaps and overlap

Compare the pages on the current site with the questions B2B buyers ask at different stages: what the problem is, how to assess options, and what a solution involves. A content gap may be a missing topic, but it may also be a page that fails to answer a useful question or make the next step clear.

Map each priority page to one primary buyer need and a relevant query theme. Then check for multiple pages competing to serve the same purpose. If two pages overlap, decide whether to combine them, distinguish their intent or keep both with clearer roles. Preserve accurate, useful material; rewrite or remove content only after checking its business and search value.

Keep the user journey in view. A search landing page should make it easy to understand the offer and move to a suitable next step. For broader decisions about how page structure supports a B2B sales path, see how to choose website architecture around the sales path.

4. Map the URL structure before development

Create a URL mapping sheet with one row per current page. Include its current address, purpose, priority, proposed destination and migration action: keep, change, combine or remove. Where an address changes, identify the closest equivalent new page and plan a direct permanent redirect. Avoid sending unrelated old URLs to the homepage; that does not preserve the original page's usefulness for visitors.

Review the proposed structure for clear, consistent paths. Make sure key service and industry pages remain discoverable through navigation and contextual internal links. If a page is intentionally retired without a replacement, document the reason and check its links and search value before removing it. Share the mapping with whoever controls development and migration, not only the content team.

5. Use this migration checklist

• Save the dated URL inventory and performance baseline.
• Assign an owner and action to every priority audit finding.
• Approve the content and URL map before development is complete.
• Test redirects and confirm they lead to relevant, working pages.
• Check that important pages are not blocked from crawling or indexing.
• Review internal links, titles, headings and canonical signals on the new site.
• Compare the live URL list with the map after launch and fix unexpected gaps.
• Monitor organic performance and enquiries after launch against the recorded baseline.

Run these checks on a staging version before launch where possible, then repeat the critical checks on the live site. A redesign can temporarily change how search engines process a site, so evaluate trends over time rather than reacting to one day's movement. Investigate sharp losses by checking whether important pages, redirects or indexing instructions changed.

Make the audit part of the redesign brief

A useful on-page SEO audit is a decision document, not a scorecard. It connects existing page value to the new site's content, URLs and technical requirements. The Marketing Specialists provides SEO and web design services and offers free digital marketing strategy consultations. For a redesign, bring the URL map, audit findings and business priorities to that discussion before the new structure is set.
