Website Redesign SEO for Manufacturers

The new website looks great. The launch went smoothly. Then, three weeks later, the RFQs slow down. Someone checks Google and finds that the pages that used to bring in quote requests, like the CNC turning page, the stainless enclosures page and a spec sheet engineers kept downloading, have disappeared from search. In their place are competitors.

This happens to manufacturers all the time, and it’s almost never because the new site is worse. It’s because the move broke the connection between what Google had learned about the old site and the new one. The good news is that it’s preventable. A redesign done carefully can keep your rankings, and often improve them.

The short answer

To redesign a manufacturing website without losing your Google rankings:

  1. Record what the current site ranks for, earns and converts before you start.
  2. List every page, PDF and file, and note which ones bring in traffic and links.
  3. Build the new site on a staging address that’s blocked from Google.
  4. Redirect every old page and PDF to its closest new match with a permanent (301) redirect.
  5. Keep the technical details that ranked: specs, materials, tolerances, certifications.
  6. At launch, remove the block, test the redirects and quote forms, and submit a new sitemap.
  7. Watch Search Console and RFQs closely for the first month, and keep the redirects for at least a year.

The rest of this guide explains each step, and the parts that trip up manufacturers in particular.

Why manufacturing websites are especially at risk

Most redesign advice is written for a small business with twenty pages. A manufacturing site is usually different:

  • Large product catalogs. Hundreds or thousands of part numbers, each with its own page, many of them quietly ranking for very specific searches.
  • PDF spec sheets and CAD files. Google indexes PDFs, and a spec sheet can rank on its own and collect links from engineers, distributors and forums.
  • Links you don’t control. Distributors, Thomasnet profiles, industry associations and customers often link straight to deep pages on your site, not just your homepage.
  • Discontinued products. Old part pages that still get searched long after the product changed.
  • Quote forms and tracking. RFQ forms, file uploads and conversion tracking that quietly break during a rebuild.

Every one of those is a place where years of search value can leak away if nobody plans for it.

Before you start: take an inventory

You can’t protect what you haven’t listed. Before any design work begins, build a record of what the current site has and what it’s worth.

Your best pages. In Google Search Console, open the Performance report, set the date range as long as it goes, and export the pages that get the most clicks. These are the pages that have to survive the move in good shape.

Every URL on the site. A crawler tool, such as Screaming Frog, lists every page, image and file on your current site. Save that list. It becomes your redirect map later.

Your PDFs. Search Google for “site:yourdomain.com filetype:pdf” to see which of your documents are indexed. Spec sheets and catalogs that show up there need a plan of their own.

Pages other sites link to. Search Console’s Links report shows which of your pages get the most links from other websites. Losing those pages, or their links, costs more than losing a page nobody links to.

Your conversion setup. Write down every form, where it sends its emails, and how it’s tracked in Google Analytics. You’ll test all of it at launch.

Your starting numbers. Note your monthly search traffic, the searches your top pages rank for, and how many RFQs and calls the site produced over the last few months. Without a baseline, you won’t know after launch whether something dropped or how far.

Decide how much is really changing

Redesigns come in different sizes, and the risk grows with each thing you change:

  1. Design only. New look, same pages, same addresses. Lowest risk.
  2. New page addresses (URLs). For example, moving from “/products.php?id=482” to “/cnc-turning/”. Needs careful redirects.
  3. New platform. Moving from one website system to another. Usually changes URLs, page structure and how files are stored.
  4. New domain name. The biggest change of all.

If you can, don’t do all four at once. And if your current site’s structure is sound, ask whether you need a full rebuild at all. Our guide to manufacturing website design covers when improving what you have makes more sense than starting over.

Map every old page to a new one

This is the step that saves your rankings. For every page in your inventory, decide where it goes on the new site, and set up a permanent redirect (a 301) from the old address to the new one.

Google’s guidance is clear on a few points:

  • Redirect each old page to its closest match, not everything to the homepage. A visitor, or Google, looking for your stainless enclosures page should land on the new stainless enclosures page.
  • Avoid chains. Old page should go straight to new page, not through two or three stops in between.
  • Use permanent redirects done on the server. Google says permanent redirects pass along the value a page has built up.
  • Keep them in place for at least a year. Google’s John Mueller has said a year is the minimum, and there’s no harm in keeping them longer.

For a manufacturer, a few cases need special care:

Discontinued products. If an old part page still gets searched, don’t just delete it. Redirect it to the replacement part, or to the closest category, or keep a short page that says the part is discontinued and points to what replaced it.

PDF spec sheets. New websites often store files in a new place, which changes every PDF’s address. Redirect each important PDF to its new location. Better still, put the key specs on the product page itself as text, and offer the PDF as a download.

Consolidated pages. If you’re merging five thin product pages into one strong one, redirect all five to the new page.

Links inside your own site. Redirects catch old addresses, but your new menus, product pages and buttons should link straight to the new addresses, not through a redirect. It’s faster for visitors and clearer for Google.

Don’t throw away what Google liked

Many redesigns cut text to make pages look cleaner. On a manufacturing site, that text is often exactly what ranked: the materials list, the tolerances, the industries served, the paragraph about your certifications.

Before you approve a new page, compare it with the old one. Keep the page title and main heading close to what ranked, unless you have a clear reason to change them. Keep the specific details engineers search for. A cleaner layout is great; a thinner page usually isn’t.

A redesign is also a good moment to add what the old site was missing, like a page for each capability or a few design guides engineers actually use. That’s the kind of manufacturing content marketing that keeps paying off after launch.

Build the new site where Google can’t see it

The new site should be built on a private staging address, blocked from search engines, so Google doesn’t find a half-finished copy of your website. That block is also one of the most common reasons a new site vanishes after launch: someone forgets to remove it. Put “remove the search engine block” at the top of your launch checklist.

Before launch, crawl the staging site with the same tool you used for the inventory. It will flag broken links, missing page titles, duplicate pages and slow-loading pages while they’re still easy to fix. Check the new site on a phone too, and test its loading speed, since large product photos and video headers are the usual culprits on manufacturing sites.

If your product pages use structured data (the behind-the-scenes code that tells Google a page is a product, with a part number, specs or availability), make sure the new templates carry it over. It’s easy to lose in a rebuild, and nobody notices until it’s gone.

Launch day checklist

On the day you switch over:

  1. Remove the block on search engines from the new site, and check that the site’s robots.txt file isn’t blocking important pages. Make sure each page’s canonical tag (which tells Google the page’s main address) points to the new live address, not the staging one.
  2. Turn on the redirects and test your top 50 pages from the inventory. Each old address should land on the right new page in one step.
  3. Test your PDFs the same way.
  4. Submit your new sitemap in Google Search Console.
  5. Test every quote form. Submit a real request with a file attached and confirm the email arrives and the conversion is tracked.
  6. Compare against your starting numbers over the following weeks, so you know quickly if anything has dropped.
  7. If you changed domain names, use the Change of Address tool in Search Console. It’s only for domain moves, and it only works once your redirects are in place.

After launch: watch, then fix fast

Expect some movement in the first weeks while Google works through the changes. Google doesn’t publish a timeline for this, and it varies with the size of the site and how much changed. What matters is catching real problems early:

  • Check Search Console every few days for pages Google can’t find (404 errors) and for pages dropping out of the index. Add redirects for anything you missed.
  • Compare your top pages from the inventory with how they’re doing now.
  • Watch RFQs, not just traffic. If quote requests drop while traffic holds steady, the problem is likely the forms or the new page layouts, not Google.
  • Ask key partners to update their links. Your distributors, your Thomasnet listing and industry associations should point to your new page addresses. Redirects cover you in the meantime, but direct links are better, and those industry links are the core of link building for manufacturers. If you’re reviewing your Thomasnet spend at the same time, see is Thomasnet worth it.

If a page that used to bring in RFQs is still missing after several weeks, look at it closely: is the redirect working, did the content change, is the page blocked or slow?

A simple timeline

  • Two to three months before launch: take the inventory and decide what’s changing.
  • A month before: finish the redirect map and review new pages against the old ones.
  • One to two weeks before: test redirects and forms on the staging site.
  • Launch day: work through the checklist above.
  • The first month after: check Search Console and RFQs every few days and fix anything that’s missing.
  • For the next year: leave the redirects alone.

Mistakes we see most often

  • Redirecting everything to the homepage. Google treats that much like a missing page.
  • Launching with the search engine block still on.
  • Changing every URL for no real reason.
  • Deleting old product and PDF pages that still had search traffic.
  • Cutting the technical details from pages to make them look cleaner.
  • Forgetting the forms. A beautiful site that drops quote requests is a step backward.

Many of these are the same problems we describe in why most manufacturing websites fail at SEO, just triggered by a redesign instead of built in from the start.

Who should handle this

Your web designer builds the new site. Someone also needs to own the search side: the inventory, the redirect map, the content checks and the launch testing. Many design firms don’t do this in depth, so ask them directly who handles redirects and what their plan is for your PDFs and product pages.

It’s the work we do under website optimization and technical SEO for manufacturers, and it’s far cheaper to plan before launch than to repair after. A redesign is also the right time to plan the pages that win new business, which is the heart of industrial SEO and B2B SEO for manufacturers. For the foundations a new site should be built on, see technical SEO for industrial websites.

The same steps apply whether you’re a parts maker in Grand Rapids, a fabricator near Cleveland or an equipment builder in Houston. The risks are always the same: catalogs, PDFs and forms. You can see all the regions we work in.
