Top 10 Questions to Ask an Engineering Web Design Agency

You've been here before. Another agency pitch deck full of slick screenshots from clients who make trainers, or coffee, or skin cream. The agency rep nods sympathetically when you explain that your buyers specify hydraulic seals, or pressure transmitters, or precision-machined components for offshore wind, and then they show you a page from a craft beer brand and say "we can adapt this approach for engineering". Hmmm.

If you're a marketing leader at an engineering or manufacturing company, this is the part of the agency hunt that grinds you down. Generic portfolios, generic case studies, generic claims about lead generation. None of it tells you whether the agency actually understands the way your customers buy, the length of your sales cycle, or the difference between a curious tyre-kicker and a real specification opportunity.

We're Red Evolution, a B2B web design and digital marketing agency that's been working with engineering, oil and gas, technology and industrial manufacturing companies for over 20 years. Yes, we have an obvious bias here, we'd quite like you to talk to us. But this post isn't a sales pitch. It's a list of the 10 questions we'd want you to ask if you were sitting opposite us, or any other agency, looking for engineering lead generation web design that actually pays for itself.

Use it as a checklist. The good agencies will welcome the questions. The ones who go quiet should probably stay quiet.

1. Can you show me real lead generation numbers from engineering or industrial clients?

Not "we increased traffic by 300%". Traffic isn't a result, it's a vanity metric. Ask for actual lead counts, quote requests, opportunities created, pipeline value, and revenue closed. Then ask whether those leads matched the client's ideal customer profile, because a hundred leads from students writing dissertations is worse than two from buyers ready to specify.

A good agency will have at least one or two case studies where the numbers are specific and the buyer profile is described properly. If every example they show you is from a B2C ecommerce brand or a SaaS startup, they probably haven't built many B2B lead generation websites for industrial customers. That doesn't make them dishonest, it just makes them the wrong fit for what you're trying to do.

If you want to know what good looks like, our post on how to build a lead generation website walks through the methodology we use, with the kinds of metrics worth reporting against.

2. How will you get to know our products, customers and sales cycle before designing anything?

This is the test. A web design agency for engineering firms that wants to start sketching wireframes in week one is treating you like every other client they've ever had. That's a problem when your buyers are specifying engineers, plant managers and procurement teams who all want different things from your site, and when a single deal might involve six months of technical conversations before anyone even mentions price.

Look for an agency that wants to spend time with your sales team, your technical team, and ideally a couple of your actual customers. Discovery should feel like an interrogation, not a kick-off. If they're not asking you uncomfortable questions about why deals are won and lost, they're guessing.

3. Who's actually going to write our content?

Engineering content is the part where most agencies fall over. They'll either dumb it down to a level that insults your buyers, or they'll fluff it up with vague nonsense about "innovative solutions" and "trusted partners" that says precisely nothing. Neither version converts.

Ask who'll be writing. Will it be a senior writer with industrial experience, or a 22-year-old fresh out of an English degree who has to Google what an actuator is? Both can produce passable output, but only one can write a page that ranks for "stainless steel pneumatic actuator IP67" and converts the engineer who searches it.

Our view, having done this for two decades and got plenty wrong along the way, is that you can teach a good writer the technical detail. You cannot teach a non-writer to write. Either way, ask the question and ask for samples in your sector.

Our guide to content marketing for engineering companies goes deeper into this if you want a proper read.

4. How will the website connect to our CRM and our sales process?

A B2B lead generation website is only as useful as the system it feeds into. If form fills go to a generic inbox that nobody owns, or if the sales team has no visibility of who downloaded what, you're throwing leads away every week without realising it.

Ask the agency about CRM integration in detail. HubSpot, Salesforce, Microsoft Dynamics, Zoho, whichever platform you use. Ask about lead routing, lifecycle stages, attribution and automation. If the answer is "yeah, we'll embed your forms", they're simply building a brochure with an inbox attached.

We're HubSpot Partners and, although we try to remain unbiased about which CRM we recommend, we definitely have a favourite. We've explained why we almost always recommend HubSpot's CRM in another post if you want to read why. But the question matters whatever platform you've got.

5. What's your CRO process for technical buyers?

Conversion rate optimisation (CRO) for engineering sites is a different beast to CRO for direct-to-consumer brands. Your buyers don't impulse-purchase a £40,000 piece of capital equipment because the call-to-action button was orange instead of blue. 

Real CRO for technical buyers is about reducing friction across a long, considered process. Clear technical specifications, downloadable datasheets, easy access to a real human, and trust signals that matter to engineers like accreditations, case studies, past projects and materials traceability.

Ask the agency what they actually test, how they prioritise tests, and how long they expect a test to run before drawing conclusions. If the answer involves heat maps and button colours and not much else, keep looking.

6. How do you handle long, multi-stakeholder sales cycles in your reporting?

In industrial manufacturing website design, the buyer journey can run for six, twelve, even eighteen months. Multiple people get involved over that period: the engineer who specified, the buyer who priced it, the manager who signed off, the QA team who approved the supplier. A simple "we generated X leads this month" report tells you nothing about which of those leads are real opportunities six months out.

Ask whether the agency reports at the account level as well as the lead level. Ask whether they look at multi-touch attribution, not just last-click. Ask how they tie content engagement to pipeline. If they only know how to count form fills, they're not equipped for the complexity of B2B sales cycles, which is most of what engineering marketing actually is.

7. What's your approach to SEO and AI search for our market?

Search has changed a lot in the last couple of years, and engineering search has changed in particular ways. The volumes are low, the queries are technical, the buyers are often specifiers using application-led language that nobody else searches for. On top of that, AI search engines like Google's AI Overviews, ChatGPT and Perplexity are now answering questions before the user clicks anything at all. That changes how content needs to be structured, what it needs to say, and how you measure whether it's working.

Ask the agency how they research engineering keywords (they should know the difference between transactional and informational intent, and they should be perfectly comfortable with technical specifications as search terms). Ask how they think about AI search, and what they're doing differently because of it. We've written about AI search and what it means for engineering companies if you want the longer version. The short version: any agency still selling 2018-style "blog three times a week, stuff in keywords" is selling you yesterday's playbook.

8. What's the plan for the 12 months after launch?

This is where most agency relationships fail. The site goes live, the project team disbands, the developer moves to a new client, and six months later you're staring at a website that hasn't been touched while your competitors quietly improve theirs every week.

Ask what happens post-launch. Is there a retainer model? Is there a structured process for ongoing improvement? We're a strong believer in growth driven design, the principle that a website is never finished, and our post on growth driven design explains why the launch is the start of the work, not the end. Whatever the agency calls their post-launch model, it should be a real, structured thing, not a vague offer to "be there if you need us".

9. What KPIs will you report on every month, and what does the report actually look like?

A monthly report should make sense to your CFO, not just your marketing team. If the report is full of impressions, reach, bounce rate and engagement scores, you're paying for activity reporting, not results reporting.

Ask to see a sample report. The good ones show qualified leads, opportunities, pipeline value, attribution back to source, and a clear narrative about what changed and why. The mediocre ones show traffic graphs and a paragraph of marketing speak. Your finance director will sniff that out in twenty seconds, and so should you.

10. Will you tell us when something we want is a bad idea?

This is the honesty test. Every agency will say yes to this in the meeting, of course they will. The way to know if they actually mean it is to listen for whether they've already pushed back on anything you've said.

Have they questioned your assumptions about your audience? Have they suggested cutting a feature you said you wanted? Have they admitted that something you proposed probably won't work? If everything you've said has been met with enthusiastic agreement, you're in danger of wasting your budget on some wild, wish-list ideas.

Our experience, scaling engineering company marketing programmes for clients across the UK, is that the projects which work best are the ones where the client and the agency disagree productively. The agencies that just say yes to everything are easier to work with for about three weeks, and then it all goes sideways. There's a reason we wrote a post on why client and agency relationships fail, and most of it comes back to this.

Putting the questions to use

Print these out, take them to your next agency meeting, and watch what happens. The agencies who answer with specifics, named clients, real examples and the occasional "actually, we got that one wrong once" are the ones worth a second meeting. The ones who answer with platitudes and case studies from completely different industries can go in the no pile with a clear conscience.

If you'd like to put the questions to us, we're happy to answer them. No deck, no pitch, no hard sell, just a 15-minute call where you ask the awkward ones and we tell you straight whether we think we're the right agency for what you're trying to do. If we're not, we'll usually be able to point you at someone who is.
