Launching a new website for a building product manufacturer should feel like progress. But too often, the pressure to go live leads to rushed launches, and the consequences follow quickly: broken product selector tools that frustrate specifiers, missing technical downloads that lose trust, or mobile layouts that fall apart when an M&E engineer tries to check a datasheet from site. For a construction marketing agency UK working across the supply chain, we see these issues repeatedly. The solution is not more time or bigger budgets. It is a systematic pre-launch checklist that catches problems before they reach your audience.
This is that checklist.
Start with what should work, but often does not.
Test every link. Internal navigation, footer links, product category pages, case study references. Click them all. Broken links do not just frustrate users. They signal a lack of care, and in a sector where specifiers rely on technical precision, that impression sticks.
Check every form. Contact forms, technical enquiry forms, sample request forms, CPD booking forms. Submit test entries and confirm they reach the right inbox. Check the autoresponder. If a specifier requests a datasheet and hears nothing, you have lost them.
Verify file downloads. Every PDF, CAD file, BIM object, NBS specification clause, installation guide, and product brochure. Open each one. Confirm the file name makes sense when saved. A file called "final_v3_updated_FINAL.pdf" does not inspire confidence.
Test site search. If your website includes search, use it the way your audience will. Search for product codes, application types, British Standards references, material types. If it returns nothing useful, it is worse than not having search at all.
Your audience judges you on the precision of your product information. A marketing site for a consumer brand might survive a typo. A building products marketing agency knows your audience will not be as forgiving.
Audit technical specifications. Check dimensions, weights, loadings, thermal values, fire ratings, acoustic performance. Cross-reference against your latest product data. If the website contradicts the datasheet, the datasheet wins, and the website loses credibility.
Confirm certifications and compliance. Check that CE marks, UKCA marks, British Standards references, BBA certificates, and third-party accreditations are current and correctly stated. Out-of-date certification information is not just embarrassing. It can create legal and commercial risk.
Review NBS references. If your products appear in NBS specifications, make sure the clauses, codes, and section references on your website match the current NBS year. Specifiers notice when they do not.
Check imagery and captions. Confirm that project photography shows the correct product, and that captions accurately describe the application. If an image is labelled as a healthcare project but shows a retail fit-out, someone will notice.
A slow website does not just frustrate users. It actively costs you enquiries. Specifiers and contractors will not wait for a product page to load. They will move to your competitor instead.
Test page load speed. Use a tool like Google PageSpeed Insights or GTmetrix. Focus especially on product pages and technical resource libraries, where image-heavy content often drags performance down. Aim for load times under three seconds on a standard connection.
Optimise images. Large, uncompressed images are one of the most common culprits. Resize and compress product photography, technical diagrams, and project case study images before upload. Your Webflow agency UK should handle this during build, but it is worth a final check.
Check mobile performance separately. A site that loads quickly on desktop can still struggle on mobile, especially if it is serving full-resolution images to a 4G connection on site. Test on real devices where possible, not just browser emulators.
Your audience is not always at a desk. M&E engineers check datasheets in plant rooms. Contractors compare products on site. Fit-out specifiers review options on tablets during client meetings. If your website does not work in those contexts, you are excluding a significant portion of your audience.
Navigate the site on a phone. Try finding a product, downloading a datasheet, and submitting an enquiry. If any of those tasks feel awkward or slow, they need fixing.
Test form usability on mobile. Long forms with small input fields are painful on a phone. Check field sizes, button tap targets, and whether autofill works as expected.
Check PDF readability on small screens. Technical PDFs that are readable on a desktop monitor can become illegible on a phone. If your datasheets rely on small text or detailed tables, consider offering mobile-friendly alternatives or HTML versions for key content.
Even the best website is useless if no one can find it.
Review page titles and meta descriptions. Every product page, category page, and key landing page should have a unique, descriptive title tag and meta description. Avoid duplication. Avoid generic placeholders like "Home" or "Products."
Check heading structure. Confirm that each page uses a single H1 heading, and that subheadings follow a logical hierarchy. This helps both search engines and screen readers understand your content structure.
Set up Google Search Console and Analytics. If they are not already configured, do it before launch. You need baseline data from day one to measure performance and identify issues early.
Submit an XML sitemap. Ensure your sitemap is generated, accurate, and submitted to Google Search Console. This helps search engines index your site efficiently.
Proofread everything. Twice. Typos, grammatical errors, and inconsistent terminology undermine trust. Read your content aloud if it helps you catch mistakes.
Check contact details. Phone numbers, email addresses, office addresses, social media links. Confirm they are correct and up to date across every page where they appear.
Review legal and compliance pages. Privacy policy, cookie notice, terms and conditions. These are not exciting, but they matter. Make sure they reflect current legislation and your actual practices.
Test in multiple browsers. Chrome, Safari, Firefox, Edge. Your site should work in all of them. Do not assume.
A proper pre-launch checklist does not add weeks to your timeline. It adds a day or two of focused attention that prevents months of credibility damage. For construction supply chain businesses, where trust is built slowly and lost quickly, that time is worth it.
