Our product pages say exactly what every other distributor's say. Should we rewrite them?
Not all of them, and never the specifications. Copying the manufacturers' descriptions won't earn a Google penalty, but when a search matches text many sites share, Google tends to show one of them, and a buyer comparing distributors sees no reason to pick yours. The fix is adding what only you know: which branch stocks it, lead time, the part numbers it replaces, and what it's used with. Start with the few dozen products buyers search for and ask inside sales about most, not the whole catalog.
What it usually means
Hardly anyone decided to do this. A distributor's catalog gets built by loading the manufacturers' data, from a spreadsheet, a data feed or an industry data service, because writing twenty thousand descriptions by hand was never realistic. Part of that is exactly right. A pressure rating, a bore diameter or a temperature range should match the manufacturer's sheet character for character, and a paraphrased spec is a wrong order waiting to happen. So the copied text isn't the mistake. The mistake is that the manufacturer's text is all the page says.
What's missing is the distributor's half of the page. The manufacturer can say what a part is, and its specs should stay word for word. Only you can say which competitor's or older part number it crosses to, what it's usually installed with, and what your counter tells people who call about it. Add whether it's stocked, at which branch, and who picks up the phone, and you have the reasons someone buys a part from one distributor over another selling the identical item. A page built from a catalog load shows none of them. Distributor marketing makes the branch and lead-time case for the whole site, through the line card and the capability page. This is the same gap one product page at a time, where cross-references and application notes carry most of the weight.
Rule out a different problem before anyone rewrites a word. If your product pages get almost no impressions in Search Console, Google may not be indexing them, or the specs may sit in PDFs and filters it can't read, and new copy won't fix either. Sameness looks different: the pages are indexed and do get impressions, but they sit below the manufacturer and the bigger distributors, and the calls about those parts go somewhere else. Steps 1 and 3 below tell the two apart.
What it costs while it stays this way
Not a penalty, by Google's own account. Its 2008 Search Central post on the so-called duplicate content penalty says there's no such thing in the way most people mean it, then explains the real effect: Google tries to filter out duplicate documents, because it wants a results page of different answers rather than ten copies of one. Google's John Mueller said much the same about online-store product descriptions in 2021: no penalty when the rest of the site is different, but when a search matches only the shared description, Google picks one of those pages and shows that one. A search for the part number itself can still turn up several distributors, and what separates them there is everything else on the page. The 2008 post also takes up sites built on someone else's listings, using Amazon affiliates as the example, and asks how they could outrank Amazon with the exact same listing unless they'd added significant value. Swap in the manufacturer, or the largest distributor in your category, and that's the position a copied product page is in.
Google's guidance on helpful content, updated in October 2026, asks a question that reads as if it was written about distributor catalogs: when content draws on other sources, does it avoid simply copying or rewriting them, and instead provide substantial additional value and originality? It also asks whether a page offers substantial value compared with the other pages in the results. Google offers these as questions to judge your own pages by, and says its ranking systems are built to prioritize helpful, reliable information made to benefit people. A product page that's the manufacturer's paragraph plus a request-a-quote button answers no to both.
The buyer's version is faster. A maintenance buyer who opens three distributors' pages for the same part and reads the same paragraph three times has nothing to separate them on except price and whoever answers the phone first. An AI assistant asked to compare suppliers is in the same spot: it can only repeat what it reads, and three identical pages give it nothing to say about any of them.
Copied text also goes out of date on someone else's schedule. When the manufacturer revises a dimension, every page loaded from last year's file now disagrees with the current spec sheet, and the buyer has to call to find out which one is right. Who should own that product data is its own decision, and the copied paragraph is often the first place the drift shows.
How to confirm it yourself
- Search one of your own sentences in quotation marks. Open the product page for a part you sell often and copy one full sentence from its description: prose, not the part number. Paste it into Google inside quotation marks, which Google's search help documents as the operator for an exact match. Every result is a page carrying that sentence word for word. If Google ends the list with a note that it left out entries very similar to the ones shown, click the link to repeat the search with them included, or your count will come out low. Write down how many there are, whose page sits on top, and whether yours appears at all. Repeat with two products from other lines. If the manufacturer and several distributors show your sentence above you, the symptom is confirmed.
- Put your page beside three others for the same part. Open the manufacturer's page for the same part number and two competing distributors' pages in tabs next to yours. For each one, note whether it shows stock status, which branch or warehouse holds it, a lead time when it isn't stocked, the part numbers it replaces or crosses to, an application or compatibility note, and a named person or direct number. Count the items only your page has. Zero is the symptom in its plainest form, and the list you just wrote is what belongs on the page.
- Read your product pages' numbers in Search Console. In Search Console, open Performance, then Search results. Average position is off by default, so click the Average position box above the chart to show it next to clicks and impressions. Set the date range to the last 12 months, choose the Pages tab, and add a Page filter for URLs containing the folder your product pages share, such as /products/. Sort by Impressions. Pages with impressions, few clicks and an average position past the first page are being shown and passed over; those are the candidates. Copy is one possible reason among several, including a thin template or a page with no availability on it, and steps 1 and 2 tell you whether it's this one. Click one, then the Queries tab, to see which searches it showed for: part numbers, brand names, brand plus city. Pages with almost no impressions are the other problem from the diagnosis above, so run one through the URL Inspection bar at the top before rewriting it.
- Pull the parts people actually ask about. Export the last 12 months of quotes or order lines by part number from your ERP or quoting system and sort by count. Then ask inside sales two questions: which 20 parts do they get called about most, and which parts do they most often cross to another brand or a newer number. Where those two lists overlap the pages from step 3 is your first rewrite list. Keep it short; a few dozen pages is a sensible first batch. If inside sales needs a day to answer, the rest of the check doesn't wait on them.
- Read the agreements behind your short list for content terms. Only the lines behind the parts on your step-4 list matter for now. For each of those manufacturers, search the distribution agreement, and any brand or co-op marketing guidelines that came with it, for content, marketing materials, trademark, images and product information. Some manufacturers ask that their descriptions and specifications appear unaltered, or supply the data under license. A clause like that governs the manufacturer's text; whether you can add your own stock, cross-reference and application details beside it is a separate question, so find the clause before anyone edits the manufacturer's paragraph.
What you'll hear about it
The advice comes from web vendors, SEO consultants and the manufacturers' own reps. Each of these is partly true.
“Duplicate content will get you penalized by Google.”
Not by Google's account. Its own 2008 post on the subject says the penalty, as most people mean it, doesn't exist, and John Mueller said in 2021 that reused product descriptions don't draw one when the rest of the site differs. The real effect is quieter: for a search that matches the shared text, Google usually shows one version, and the cost is being a version it doesn't show. A rewrite sold on penalty fear is sold for the wrong reason, even when some rewriting is right.
“We can rewrite the whole catalog with AI by next month.”
Rewording the same facts adds nothing a buyer or Google can use, and Google's helpful-content questions name rewriting sources, not just copying them. Its spam policies cut both ways. The scraping examples include republishing other sites' content without adding original content or value, which is close to a bare catalog load, and copying content with only slight changes, such as synonyms or automated techniques, which is close to a bulk reword. Both are defined by the purpose of manipulating search rankings, as is scaled content abuse, whose examples include using generative AI tools to produce many pages without adding value for users. A licensed catalog put up to sell parts is neither, and rewording it doesn't move it anywhere useful. A bulk reword can also change a spec without anyone noticing. What helps is information the manufacturer doesn't have.
“Just add a canonical tag pointing at the manufacturer's page.”
A canonical tag tells Google which URL is the main version of a page. Pointed at the manufacturer, it asks Google to show their page instead of yours, which is the opposite of the goal. The tag is mostly for your own duplicates, like the same product reachable at two addresses on your site. Across domains, it tells Google the other site's page is the original, which is exactly what you don't want here.
“We have to use the manufacturer's approved copy.”
Sometimes true, and step 5 tells you. Read what the clause covers. Approved copy governs what the manufacturer's paragraph says; whether you can add stock, branch and cross-reference details beside it is usually a different sentence in the agreement, and it's the one worth finding.
What actually fixes it
A healthy product page has two halves. The manufacturer's half stays exactly as published: specifications as separate fields rather than a paragraph, the part number, the spec sheet linked, and their description if the agreement calls for it. The distributor's half is yours: whether it's stocked and at which branches, a lead time when it isn't on the shelf, the part numbers it replaces or crosses to as plain text, a short note on what it's used for or installed with, and the name or direct line of whoever answers questions about that line. Most of it comes from data you already hold, though not all of it is a simple field. Stock and lead time live in the ERP, so getting them onto the site is a data sync, not a template change, and a stale "in stock" is worse than none. A workable answer is a stocked or non-stocked flag per branch from a nightly export rather than a live count; if even that flag won't be kept current, leave it off and let the page say which branch to call. If your pages show a price and take orders, Google's merchant listing structured data has an availability property (in stock, out of stock, backorder) that carries the same flag in a form Google reads; quote-only pages aren't eligible for merchant listings. Cross-references come from inside sales' own lookup sheets, and the notes from what the counter says when someone calls.
Write by family, not by part. One application note written for a family of ball valves or a bearing series covers every size in it, and the per-part fields fill from data. So the work runs in this order: the template fields first, because they change every product page at once, with the stock flag switched on once the export behind it runs reliably; then hand-written notes for the short list from step 4; then the category pages those parts sit in, which a buyer often reaches before any single part. When a manufacturer retires a part, the old number goes on the replacement's page as text, the same move discontinued product pages describes from the manufacturer's side. The long tail of slow-moving parts can keep the manufacturer's text with the data fields added, and that's a reasonable place to stop.
Measure it on the pages you changed. Run the same Search Console filter on the rewritten pages for the months before and after, and ask inside sales whether calls about those lines have changed. Give it time, because Google has to recrawl a page before a change can show. If the current product template can't hold the new fields, that's a rebuild question, covered on industrial website design. Photos are a separate question: a real photo of your stock or kitting adds information, and the manufacturer's photo still does the job of identifying the part.
The message to send
To whoever maintains your website, with your inside sales lead copied. It asks for the data and the template change in one go, and it carries a date.
Hi [name],
We're changing how our product pages work. Right now they carry the manufacturers' descriptions and nothing else, so they read the same as every other distributor's. We want to keep the manufacturers' specifications exactly as they are and add our own information beside them.
Could you send us, by [date two weeks out]: a Search Console export of every page under [/products/] for the last 12 months, with impressions, clicks and average position; and what it would take to add five fields to the product template: a stocked or non-stocked flag by branch from a nightly ERP export, lead time when not stocked, cross-reference part numbers as text, an application note per product family, and a contact for the line. Please also confirm whether the specifications are stored as separate fields or as one block of text.
[Inside sales lead], by the same date, could you list the 20 parts you're called about most and the parts you most often cross to another brand? We'll write the first batch from those two lists.
Common questions
How to check for duplicate content?
For copied product text, the quickest check is Google itself: paste a full sentence from your page into the search box inside quotation marks, and every result is a page using the same words. For duplicates inside your own site, Search Console's Page indexing report lists pages Google treated as duplicates, and the URL Inspection tool shows which URL Google selected as the canonical.
Why is having duplicate content an issue for SEO?
Not because of a penalty. For a search that matches the shared text, Google usually shows one of the pages carrying it, so the rest compete for that slot and most don't get it. A search for the part number can show several distributors, and then what separates them is everything else on the page: stock, cross-references, application notes, a person to call. A page that's only the manufacturer's paragraph has none of that to offer.
Should we change the manufacturer's specifications when we rewrite?
No. Specifications should match the manufacturer's spec sheet exactly, because a reworded figure is how wrong parts get ordered. Keep them as separate fields so they can drive filters, and put the effort into the information around them.
Can we use AI to rewrite our product descriptions?
As a drafting aid for notes your own people supply, yes. As a way to reword the manufacturer's paragraph across the catalog, it produces new words with the same information, which helps neither the buyer nor Google, and it can quietly alter a specification. Whatever writes it, the test is whether the page now says something the manufacturer's page doesn't.
How many product pages should a distributor rewrite?
Fewer than most expect. Add the data fields to every page through the template, then hand-write notes only for the products buyers search for and ask about most, plus the category pages above them. The rest of the catalog can keep the manufacturer's text.
