SEO for distributors: ranking thousands of product pages
SEO for distributors: how to handle faceted navigation, duplicate manufacturer descriptions, crawl budget and part numbers across thousands of products.
SEO for distributors works when Google spends its time on the pages that sell. Those are categories, brands and products with useful content and clear part numbers. The three biggest obstacles are faceted navigation, copied manufacturer descriptions and crawl time wasted on low-value URLs.
A B2B distributor can list tens of thousands of products from hundreds of manufacturers. Every filter, sort order and variant can create a new URL, and much of the product text is the same text other resellers use.
This post explains how to fix each problem, in the order we would tackle them on an enterprise distributor’s site.
Why SEO for distributors is different
A manufacturer’s site describes its own products. A distributor’s site lists other companies’ products, often the same ones its competitors list.
That creates four problems a typical B2B site does not have.
- Scale. Product counts can run into the tens or hundreds of thousands, so manual fixes do not work. Changes must happen at template level.
- Duplication. Manufacturers often supply the same descriptions to every reseller, so many sites carry identical product text.
- URL growth. Filters for brand, size, voltage, material and stock can combine into millions of URLs.
- Part number searches. Many buyers search for an exact part number. A small formatting difference can decide whether your page appears.
The rest of this post takes each one in turn.
For a benchmark of the manufacturers you sell for, our industrial SEO research compares how the 88 manufacturers in the S&P 500 perform in Google and AI search.
Source: Industrial SEO Report 2026, Ahrefs data, October 2026.
The chart shows the ten industrial companies in the S&P 500 with the most search traffic. W. W. Grainger, the only distributor among them, gets about 655,000 US visits a month, second only to Sherwin-Williams. It also ranks in Google’s top 20 for about 96,000 keywords, more than any other company in our report. A page for each product gives a distributor that reach, as long as search engines can crawl and understand those pages.
Crawl budget: when it matters for a distributor
Crawl budget is the number of URLs Google can and wants to crawl on your site. Google says it depends on two things: crawl capacity limit and crawl demand.
Google’s guide is aimed at sites of a certain size, though it calls its figures a rough estimate. It covers sites with 1 million or more unique pages that change about weekly. It also covers sites with 10,000 or more pages that change daily.
Many distributors can fit the second group, because prices and stock levels change every day. The guide also applies to sites where Search Console marks a large share of URLs as discovered but currently not indexed.
Google’s advice for these sites includes consolidating duplicate content and blocking unimportant URLs with robots.txt. It also recommends returning 404 or 410 for removed pages, keeping sitemaps up to date and avoiding long redirect chains.
Faceted navigation: decide which filters deserve a page
Filters help buyers, but they often create the largest crawl problem on a distributor site. Google says crawlers “will typically access a very large number of faceted navigation URLs”, which leaves less time for new, useful pages.
The fix is to decide, filter by filter, which combinations should be indexable. A small number match real searches. Most do not.
| Filter type | Example | Usual treatment |
|---|---|---|
| Brand within a category | Brand X circuit breakers | Make indexable as a proper landing page if people search for it |
| Key specification within a category | 24V relays | Make indexable if search demand exists, with its own title and text |
| Sort order | Price low to high | Block crawling with robots.txt |
| Stock or availability | In stock only | Block crawling with robots.txt |
| Price ranges | Under $50 | Block crawling with robots.txt |
| Several filters combined | Brand + voltage + colour + pack size | Block crawling, unless the combination has clear search demand |
| Combinations with no products | Any filter set that returns nothing | Return a 404 status, as Google recommends |
For filtered URLs you do want crawled, Google recommends using the standard “&” separator. It also says to keep the filter order fixed so the same combination never appears under two URLs.
Canonical tags pointing filtered URLs to the main category can help over time. Google describes this as a weaker signal than blocking crawl with robots.txt.

Duplicate manufacturer descriptions
If your product page uses the same description as many other resellers, Google has little reason to choose yours. The answer is not to rewrite every product, which is rarely possible at distributor scale.
Instead, add what only you can offer, starting with the products that matter most. We usually sort products into three tiers.
| Tier | Which products | What to add |
|---|---|---|
| 1 | Top products by revenue and search demand | Original descriptions, application notes, compatible parts, questions buyers ask your sales team |
| 2 | Steady sellers | Structured specification tables, cross-references, stock and lead time, downloadable datasheets |
| 3 | Long tail | Clean templates: correct part numbers, specifications, brand and category links |
Distributors hold information manufacturers do not publish. That includes live stock, lead times, minimum order quantities, local delivery options and the alternatives your team recommends.
Putting that information on the page makes it different from every other copy. It also answers the questions a buyer needs answered before they place an order.
Part numbers: get the details exactly right
For many B2B buyers, the search is the part number. A page that shows the number in a different format can miss the search.
- Put the part number in the title, heading and URL. Use the manufacturer’s exact format, including hyphens and letters.
- Cover common variations. Buyers may type a number with or without hyphens or spaces. Include the main variant in the page text where it is natural.
- List superseded and alternative numbers. When a part is replaced, show the old number on the new product’s page.
- Add product identifiers to structured data. Google lists gtin, mpn, sku and brand as recommended properties for merchant listings. It describes mpn as “The manufacturer part number”.
Structured data helps Google read the page. It does not guarantee any special display in search results.
Category and brand pages: where broader searches land
Product pages capture exact part number searches. Category and brand pages capture broader searches, such as a product type plus a brand or a specification.
Treat these pages as landing pages, not lists. Give each one a short introduction that explains the range, the main specifications and how to choose.
Link to them from the main navigation and from related product pages. Authority building should point mostly here too, because these pages usually compete for broader, higher-volume searches.
Internal links and sitemaps at scale
On a large catalogue, internal links decide which pages Google finds first and visits most often. Deep product pages that sit five or six clicks from the home page may be crawled rarely.
Use category pages, brand pages and “related products” blocks to shorten those paths. Link from high-traffic pages to the categories that matter most commercially.
Split XML sitemaps by type, such as categories, brands and products. Google recommends keeping sitemaps up to date and using the lastmod tag for changed content. Separate files also make it easier to see in Search Console which page types are not being indexed.
Discontinued products and old URLs
Distributors remove products often. How you handle those URLs affects both crawling and rankings.
If a product has a direct replacement, use a 301 redirect to the new product. If it has none, Google’s crawl guidance says a 404 or 410 status is a strong signal for Google to stop crawling the URL.
Avoid redirecting every discontinued product to the home page. It sends buyers somewhere unhelpful, and Google’s site move guidance warns against sending many old URLs to one unrelated page.
What this looks like in practice
The principles above match what we do on other large technical sites. Two of our campaigns show the pattern.
For a US B2B heating and insulation manufacturer, we analysed 71 URLs before merging three websites into one. We removed outdated URLs, set up 301 redirects and ran a technical audit until 99% of URLs were error-free. The client reports more than 50 qualifying leads a month from organic search, up from none.
For a business data provider, we sent links directly to the product pages that needed to rank, rather than the home page. Its domain rating rose from 0 to 38 between March and December 2025 (Ahrefs). Organic traffic rose from none to 4,537 visits a month.

Where to start
If your distributor site has thousands of product pages, this order of work usually gives the clearest early gains.
- Check indexing. In Google Search Console, compare the pages you want indexed with the pages Google has indexed.
- Control faceted URLs. Decide which filters deserve a page and block crawling of the rest.
- Fix templates. Make sure titles, headings, URLs and structured data carry the exact part number and brand.
- Improve category and brand pages. Add useful introductions and strengthen internal links to them.
- Add your own content to top products. Start with tier 1 and work down as resources allow.
- Build authority to category pages. Earn links and mentions that point to the pages with the most commercial demand.
Measure progress by page type, not only for the site as a whole. Track indexed pages, clicks and queries for categories, brands and products separately in Google Search Console. This shows which part of the catalogue is improving and where the next round of work should go.

Frequently asked questions
How is SEO for distributors different from SEO for manufacturers?
Distributors list other companies’ products, often with the same descriptions as other resellers. They also tend to have far more URLs, so crawl control and template work matter more.
Should every filter combination be indexed?
No. Index only combinations that match real searches, such as a brand within a category. Block crawling of sort orders, price ranges and most multi-filter combinations.
Do I need to rewrite every manufacturer description?
No. Start with your top products by revenue and search demand. For the rest, add structured specifications, stock data and cross-references.
What should happen to discontinued product pages?
Redirect them to a direct replacement if one exists. If not, Google says a 404 or 410 status is a strong signal for it to stop crawling the URL.
Does product structured data help a distributor?
It helps Google read product details. Google lists gtin, mpn, sku and brand as recommended properties for merchant listings, but no display in results is guaranteed.
When does crawl budget become a concern?
Google’s guide is aimed at sites with about 1 million or more pages, or 10,000 or more pages that change daily. Many distributors with daily price and stock updates fit the second group.
