How far does an engineer get on your website before deciding you're not a fit?
That's the question engineering marketing has to answer, and most firms never find out, because the engineer who rules them out doesn't send an email explaining why. They close the tab. The only visible consequence is a quiet inbox, which gets read as a lead generation problem and gets treated with more traffic.
More traffic doesn't fix a screening problem.
The contact form is the last step, not the first
An engineer evaluating a supplier, a contract manufacturer or a design partner works through a sequence, and contacting you sits near the end of it. Before that they're checking whether you're plausible at all: what you build, to what tolerances, in what materials, against which standards, at what volumes.
That check is deliberately fast. An engineer with a project has a list of candidates and limited time, so the first pass is about elimination rather than selection. Anything they can't confirm counts against you, because the alternative is a phone call to find out, and they have four other tabs open.
This is the shift worth understanding. The research that used to happen in a conversation with a sales engineer now happens before the conversation, unaccompanied, against whatever your website says. Our piece on what B2B buyers do between the referral and the call covers the general pattern. In engineering it's sharper, because the criteria are numeric and either you publish them or you don't.
What gets checked, and what gets you cut
The specifics vary by discipline, but the shape is consistent:
Capability at spec level. Processes, machine list, envelope and capacity, tolerances you hold routinely versus at the edge, materials you work in. "Precision manufacturing" is not a capability statement. A table of processes with real ranges is.
Standards and certifications. ISO 9001, AS9100, ITAR registration, IATF, ISO 13485, whatever governs the work. Our audit of more than 55,000 US B2B websites found certifications shown on just 1 in 5 homepages, which means publishing yours puts you in a minority by default. For an engineer, an unlisted certification usually reads as an absent one.
Evidence of similar work. Not a logo wall. What the part was, what it did, what made it hard. Engineers are pattern-matching against their own problem, and an anonymized description of a comparable job does more than a named customer with no detail.
Data they can take away. Spec sheets, CAD files, material data, tolerance charts, drawing templates. An engineer who downloads something from you has, in a small way, already started working with you.
Someone technical to talk to. Whether the first conversation is with a salesperson or an engineer changes whether they bother having it. Say which.
The format problem that rarely gets flagged
Most engineering firms do have this material. It's in PDFs.
Spec sheets, capability brochures, tolerance charts, all of it sitting behind a downloads page. That solves the human problem and creates two others. The content is much harder for search engines to weigh than page text, so the searches those numbers would match never find you. And it's largely invisible to the AI assistants that increasingly answer the first round of supplier questions. Our audit found 82% of B2B sites aren't structured for AI search to read them, and only 9% use structured data at all.
The fix is not to delete the PDFs. Engineers want the downloadable version and should keep getting it. The fix is that the same information exists as real page text first, with the PDF offered alongside it. That's a content migration, not a rebuild, and it's the highest-return work available to most engineering firms right now. The mechanics are in how to rank in AI search.
A test you can run this afternoon
Pick the three things you most want to be hired for. A process, a material, a class of part.
Open your own website on a phone, not a desktop, because a good share of this checking happens between meetings. Start on the homepage rather than the page you'd send someone. Then time how long it takes to confirm, for each of the three, that you do the work, to what limits, and under which certification.
If any of the three takes more than about thirty seconds, or ends with "you'd have to call us," you've found the leak. Our audit of more than 55,000 US B2B websites found 44% fail Google's mobile-friendly test, and roughly a third of a typical B2B site's traffic arrives on a phone, so the phone version is the one worth testing.
The second half of the test is the first contact. Look at what your enquiry form asks for. The average first-contact form in our audit runs to 12 fields and the longest we found runs to 18. An engineer who's decided you're plausible and wants to send a drawing should be able to do that in about four fields and a file upload. Everything else can be asked in the reply.
Marketing for engineering firms, sequenced
Publish capability at spec level. Put certifications on the page. Convert the PDF library into page text and keep the downloads. Describe three or four real projects with the technical detail intact. Then, and only then, worry about channels.
The order matters because every channel sends people to the same place. Spending on traffic before the screening content exists just means more engineers ruling you out faster.
Our engineering website design page covers what that looks like as a build.
