Technical SEO for Manufacturers: The 10 Fixes That Matter
Technical SEO has a bad reputation among manufacturers, and it is mostly deserved — not because it is useless, but because it usually gets sold as something it cannot be. It will not bring you traffic you do not have. It will not outrank a competitor with three times your content.
What it does is narrower and more useful: it makes sure that the pages you have already written can be found, read and indexed correctly. For a manufacturer with a catalogue, a capability page and a set of technical documents, that is where almost all of the waste is.
What technical SEO means for a manufacturer
For a manufacturer, the goal is not rankings. It is that a search engine — and, just as importantly, an AI assistant answering a buyer's question — can work out three things from your site: what you make, who you make it for, and where you are.
Every fix below serves one of those three. If a change does not make those three facts clearer or more accessible, it is not a priority, whatever it costs.
The ten fixes
1. Product pages that contain no text
The classic manufacturer site is a gallery: a grid of product photographs, each one linking to a page with three images, a model number and a "contact us for details" button.
A search engine cannot see the difference between your warehouse frame and a competitor's without words. Neither can a buyer scanning ten tabs at once.
Check: open your main product pages and count the words that describe the product itself — not navigation, not the company boilerplate.
Fix: at least a solid paragraph of description per product covering material, specification range, typical application and the options that vary. Not marketing adjectives; the facts a buyer would ask for on a call.
2. The entire product range on one page
Some sites solve the thin-content problem by putting everything on a single long page — the whole range, all specifications, all models.
The result is one page that is excellent at nothing, competing for no specific search and answering no specific question.
Check: does any single page try to cover more than one distinct product family?
Fix: one product family, one URL. A page for the frame system, a page for the cladding panel, a page for the accessory range. Each of them then has a chance to be the answer to something.
3. URLs that were written by a system
`/p_2231.html`, `/product-detail.aspx?id=88`, `/en/cp/2417/`.
These URLs carry no information, and they break the moment you change a content management system.
Check: look at the address bar on a product page. Could a stranger guess what is on the page from the URL alone?
Fix: readable, stable, hyphenated URLs built from the product name. If the better URL already exists somewhere else on the site, that is a redirect problem, not a reason to keep the bad one.
4. Every page labelled the same
If the browser tab says "Home - [Company Name]" on your home page, your product pages, your about page and your news page, you have told search engines that all of your pages are about the same thing.
Check: open five pages in five tabs and read the tab titles.
Fix: a title that names the page's own subject first, then the company. A product page's title should contain the product, in the words a buyer would use, not the internal model code alone.
5. The same page reachable at more than one address
With and without `www`. With and without `https`. With and without a trailing slash. Your home page may exist at eight addresses, and you will be earning credibility for all of them separately.
Check: `https://yourdomain.com` and `https://www.yourdomain.com` and see whether both load without redirecting.
Fix: choose one form, redirect the others permanently (301), and make sure your internal links and sitemap use only the chosen form.
6. No sitemap, or a stale one
A sitemap is the plainest possible statement of "here are my pages". Many manufacturer sites either do not have one or have one listing pages that were deleted years ago.
Check: open `/sitemap.xml`. Does it list your current products?
Fix: generate it, submit it in the search console for your primary search engines, and make sure it updates when you add a page.
7. Images named `IMG_2231.jpg`
Image file names and alt text are the only words attached to a photograph. Left at camera defaults, they say nothing.
Check: look at the file name of the main image on a product page.
Fix: name files for what they show, hyphenated and in English, and write alt text that describes the image's content — the product and the context. Product photographs taken in your own workshop also have a second use here: they are evidence that the workshop exists.
8. Slow on a phone
Manufacturers' sites are image-heavy, and the images are usually uploaded at camera resolution and left that way. On a phone on a hotel connection, the page can take long enough that the buyer leaves before reading the specification.
Check: open your site on a phone, on mobile data, and watch the product image load. Then check what proportion of your homepage weight is images.
Fix: compress images, serve them at the size they are displayed, and make the first screen load without waiting for the whole page. This is usually the highest-effort item on this list and worth doing properly once.
9. Language versions that do not point at each other
If you have English, Spanish and Russian versions of the same page, and none of them tells a search engine that the others exist, you are running several unrelated sites that happen to share a domain.
Check: view the page source on two language versions of one product page. Look for `hreflang` tags.
Fix: each language version should declare itself and point to the alternatives, including a default. Get this wrong — for example, pointing every language at the English page — and you will suppress the very pages you were trying to serve.
10. Nothing on the site worth linking to
The fixes above make your existing pages readable. None of them makes anyone want to reference you.
Check: list the pages on your site that a technical journalist, an association or another manufacturer would have a reason to point at. Most manufacturer sites have none outside the homepage.
Fix: publish the things that get cited in your industry — a specification table, a loading or compliance explanation, a document that answers a question buyers keep asking. These pages accumulate links without any outreach, because they are genuinely useful and easy to reference.
The pages most likely to earn that kind of reference are the ones that answer the questions buyers actually ask — the six a product page should answer.
The order to do them in
Do not treat this as ten equal tasks. The sequence matters.
First, be readable. Items 1 to 7 decide whether a search engine can work out what you sell at all. If your product pages have no text, no URL and no title, nothing else on this list compensates.
Second, be fast enough. Item 8 costs the most effort and produces the least visible change — until it produces the largest one. Do it after the structural work, when you are not changing URLs any more and can measure properly.
Third, be clean across languages. Item 9 only matters once your main language is in order, and it is easy to make things worse while trying to make them better.
Fourth, earn links. Item 10 is not a technical task at all. It is content work, and it is the only item here that can grow, rather than merely stop losing.
What this will and will not do
It will not increase the amount of interest your market has in what you make. If nobody searches for your product, fixing your hreflang will not create demand.
What it will do is stop the leak. Most manufacturer sites with low traffic do not have a traffic problem at the top of the funnel; they have a value problem at the bottom, where the pages they have already written cannot be read properly by the systems that decide what buyers see. That gap between visitors and enquiries is a different diagnosis, and it is worth doing the technical work first — otherwise you will be measuring the wrong thing when you try to fix it.
The one thing to remember
Technical SEO for a manufacturer is not a growth channel. It is the floor.
Do these ten things and your site will be no more persuasive than it is today. It will simply be evaluated on what it actually says, instead of being hidden by how it is built. And that is the only fair test — of the site, and of the content you are about to put more effort into.
