Why Industrial E-Commerce Is Getting Worse, Not Better
Industrial e-commerce is getting worse, not better. Procurement teams that could quote a dozen parts in an afternoon five years ago now spend a full shift chasing missing specs, outdated product pages, and chatbots that cannot identify a kingpinless caster. The platforms that set the benchmark (Grainger, McMaster, Uline) have raised the floor on consumer-grade UX while the supplier catalog behind the storefront has thinned out. Here is what has actually changed, why it matters to OEM and MRO buyers, and the six signals that tell you a supplier is investing in the catalog or hiding behind the UI.

Quick Answer: UX Up, Catalog Depth Down
Industrial e-commerce storefronts have gotten faster, prettier, and more mobile-friendly. Catalog depth, supplier expertise, and lead time transparency have regressed. Buyers spend more time, not less, verifying specs and building RFQ comparisons. The gap between UX investment and catalog investment is the biggest quiet problem in B2B distribution.
- Average industrial catalog depth dropped 18% from 2020 to 2026 (CasterHQ panel of 32 distributors).
- Pages with full ICWM load ratings declined even faster: 41% of sampled pages in 2020, 23% in 2026.
- Chatbot deflection is up, human expertise coverage is down.
- AI-generated product copy has replaced spec-sheet references on 60%+ of mid-market storefronts.
Procurement tip: If a product page does not show a rated capacity with units, a citation to ICWM / ANSI / ISO, and a real manufacturer part number, assume the spec is AI-generated. Verify before issuing a PO.
What Is Actually Getting Worse
The specific regressions are measurable and repeatable across industrial e-commerce: thinner product descriptions, missing capacity citations, fewer manufacturer tech drawings, absent spec sheets, and lead times hidden behind log-in walls. These are not perception issues. They are quantifiable cuts in catalog investment.
- Median product description word count dropped from 780 in 2020 to 420 in 2026.
- Spec sheet PDFs on product pages declined 32% across sampled catalogs.
- Manufacturer tech drawings and CAD downloads declined 44% over the same period.
- Lead time disclosure moved behind log-in walls on 6 of 32 distributors.
- Static floor-load and velocity ratings disappeared from 58% of caster product pages.
Data point: Of 400+ industrial caster pages sampled across 32 North American distributors in Q1 2026, 77% failed a four-point spec-completeness test (load, dimensions, weight, ICWM citation). That number was 54% in 2020. Source: CasterHQ distributor catalog audit, 2020-2026.
The AI Chatbot Problem
AI chatbots and LLM-generated product copy are the single biggest contributor to the regression. They are fast to deploy, cheap to operate, and terrible at the one thing industrial buyers need: accuracy on specifications, capacity, and compatibility. Chatbots solve a deflection problem for the distributor and create a verification problem for the buyer.
- LLM-generated product copy hallucinates ratings and certifications at measurable rates.
- AI chat deflection hides missing SKU knowledge behind a friendly interface.
- Generic product text optimized for search ranks well but tells the buyer nothing.
- Automated spec-generation tools publish non-verifiable claims at scale.
- A supplier that cannot field a product-specific engineering question by phone is a liability, not a supplier.
The Benchmark: McMaster, Grainger, Uline, Amazon Business
The best industrial B2B storefronts set the expectation for what a specification-driven catalog looks like. McMaster-Carr leads on product-page engineering depth. Grainger leads on supplier coverage. Uline leads on inventory availability and next-day delivery. Amazon Business leads on procurement integrations. The gap between these leaders and mid-market distributors is widening.
- McMaster-Carr: real tech drawings, real load tables, real material specs, real citations.
- Grainger: 1.5 million SKUs, full ICWM citations on most caster pages, engineer-on-call.
- Uline: shallow catalog by SKU depth, deep on availability and logistics.
- Amazon Business: procurement workflow depth, supplier-level catalog quality varies.
- Mid-market distributor norm: Shopify storefront plus an AI chatbot and a thinning catalog.
| Benchmark | Catalog Depth | Spec Accuracy | Support Quality |
|---|---|---|---|
| McMaster-Carr | High | Highest | Phone + email |
| Grainger | Highest | High | Branch + phone |
| Uline | Medium | Medium | Phone |
| Amazon Business | Varies by seller | Varies | Seller-level |
| Mid-market norm | Thinning | Declining | Chatbot |
Six Signals of a Real Supplier Catalog
A disciplined procurement team can tell whether a supplier is investing in the catalog or hiding behind the UI in under 90 seconds on any product page. Six signals separate the real suppliers from the AI-generated storefronts.
- Signal 1: Rated capacity with units and a citation (ICWM, ANSI, ISO, ASTM).
- Signal 2: Manufacturer part number and brand, not a generic SKU.
- Signal 3: Spec sheet PDF or tech drawing on the product page.
- Signal 4: Lead time and stock status visible without login.
- Signal 5: A human phone number and direct email route.
- Signal 6: Content that answers spec questions (blog, guides, compatibility charts), not AI-generated filler.
| Signal | Real Catalog | Hollow Catalog |
|---|---|---|
| Rated capacity + citation | Every page | AI-generated |
| Manufacturer part number | Listed | Generic SKU only |
| Spec sheet PDF | Downloadable, dated | Missing / broken |
| Lead time visibility | Public, by SKU | Behind login |
| Phone + engineer email | Named, direct | Chatbot only |
| Supporting content | Guides, charts | AI filler or none |
Procurement heuristic: If the product page answers "Will this work for my application?" without needing to contact the supplier, the catalog is real. If the answer is "Chat with us", the catalog is hollow.
What Buyers Should Do Now
Industrial buyers cannot wait for the mid-market to catch up on catalog investment. The practical response is to build an internal procurement playbook that normalizes supplier quality before RFQ.
- Maintain a shortlist of 3-5 suppliers per category with verified spec depth.
- Reject RFQ responses missing ICWM or equivalent citations.
- Standardize an internal RFQ template with the 12 spec fields every quote must answer.
- Audit supplier spec-page quality annually. The suppliers investing now will pull ahead over the next 2-3 years.
- Prefer suppliers with named engineering contacts, not generic chat.
How CasterHQ Invests Against the Trend
CasterHQ is built on the premise that industrial buyers deserve catalog depth, not UI polish. Every collection page and product page on our site is engineered for spec-accurate procurement, not consumer-style browsing. We publish load ratings with citations. We staff a live engineering desk (844-439-4335). We do not deploy AI chatbots to field caster selection questions.
- Every collection page carries V3.5 Golden Rules compliance (ICWM cites, spec tables, FAQ schema).
- Product pages publish static, dynamic, and velocity ratings with unit-bearing citations.
- Live phone + email engineering support. No deflection to AI.
- Ships from Mansfield, TX. Inventory and lead time visible without login.
- Internal goal: operate like a $20-50M enterprise on catalog depth at our real $5.4M revenue scale.
Operator's note: If catalog depth is a competitive advantage in 2026, it will be a lethal advantage by 2028. The distance between real and hollow suppliers is widening every quarter.

Frequently asked questions
Is industrial e-commerce really getting worse?
On the metrics that matter to procurement (spec accuracy, catalog depth, supplier expertise, lead time transparency) yes. On UX and mobile experience, it is getting better. The gap between the two is the core problem.
Why are AI chatbots a problem for industrial buying?
Chatbots deflect supplier-staffing costs onto the buyer. They hallucinate specs, certifications, and compatibility at measurable rates. A chatbot cannot replace an engineer for caster selection, and a supplier that relies on one is a liability, not a partner.
What are the best industrial B2B e-commerce benchmarks?
McMaster-Carr for product-page engineering depth. Grainger for breadth and ICWM citation coverage. Uline for inventory and next-day delivery. Amazon Business for procurement integrations. Mid-market distributors are mostly regressing.
How do I audit a supplier's catalog quality in under two minutes?
Check six signals on a product page: rated capacity with units, citation to a recognized standard, manufacturer part number, spec sheet PDF, lead time without login, and a phone number to a named engineer. Three or more passes equals a real supplier.
Will the trend reverse?
Not at the mid-market level. The economic pressure on distributors pushes toward lower cost-to-serve, which means more automation, more AI, and thinner catalogs. Buyers should consolidate around suppliers investing against the trend.
