Northern Ireland’s Mechanical Engineering Sector Has a Digital Performance Problem. Here’s the Data.

b10 analysed 158 mechanical engineering firms across Northern Ireland. The findings reveal a sector-wide gap between technical excellence and digital performance and a clear opportunity for those willing to act on it.

What We Measured and Why

b10 ran a performance audit across 158 mechanical engineering businesses in Northern Ireland, scoring publicly accessible website. The focus was mobile performance which is the standard that Google uses to determine search visibility and that increasingly determines a business’s ability to make a strong first impression on potential clients.

This isn’t a theoretical exercise. Mobile now accounts for the majority of web traffic. Google’s ranking algorithm weights mobile performance directly. And for B2B businesses where reputation and first impressions matter significantly, the gap between a site that performs and one that doesn’t carries real commercial consequences.

What the Data Shows

The results reveal a significant performance gap across the sector. Only 10 firms (6%), of those analysed achieve what Google classifies as an “Excellent” mobile score of 90 or above. These are the businesses with fast, technically clean websites that load reliably on mobile, rank better in local search, and communicate competence before a conversation has even begun.

The majority of the sector, 109 firms (69%), sits in the “Needs Improvement” band, scoring between 50 and 89. These sites work, but imperfectly. Mobile visitors experience friction. Search visibility is suppressed. The commercial signal is mixed.

Most concerning is the bottom quartile: 39 firms (25%) score below 50 on mobile. At this level, the practical impact is significant as visitors are abandoning before pages load, and mobile search rankings are severely compromised.

Top-performing firms in this cohort average a mobile score of 80. Bottom performers average 36. That 44-point gap represents a measurable difference in search visibility, visitor retention, and the commercial impression a business makes on every prospective client who visits its website.

The Commercial Transformation Index

This analysis forms part of b10’s Commercial Transformation Index (CTI) — a 10-domain, 250-point framework developed to measure commercial readiness across the full range of factors that drive business revenue. The CTI goes beyond financial performance to assess the underlying commercial systems: strategy, sales process, digital infrastructure, content authority, customer experience, and more.

Website performance sits within the Digital Infrastructure domain of the CTI, but it is far from the only area the framework assesses. b10 is making the aggregate findings from its sector analysis available openly to the NI business community, with the aim of giving every business in the region a clearer picture of where they stand commercially and what to do about it.

The full interactive report for the mechanical engineering sector will be available at b10hub.com, including score distributions, sector benchmarks, and prioritised improvement recommendations.

Three Actions Any Engineering Firm Can Take Now

The good news is that mobile performance is one of the most actionable commercial improvements available to any business. Unlike market positioning or talent acquisition, website performance is entirely within a firm’s control and can be improved materially in a short timeframe.

  1. Image optimisation.
    Uncompressed images are the most common cause of poor scores in this cohort. Not the most exotic cause, the most common. Converting to WebP or AVIF format and implementing lazy loading typically delivers a 15–25 point improvement without touching any other aspect of the site.
  2. Render-blocking resources.
    JavaScript and CSS files loaded synchronously in the page head delay the browser from rendering anything visible. Deferring non-critical scripts is often a one-line change with a disproportionate impact on Largest Contentful Paint, Google’s primary mobile performance metric.
  3. Hosting and server response time.
    If your Time to First Byte is above 600ms, no amount of code optimisation fully resolves it. The fix is at the infrastructure level, managed hosting with edge caching. For firms on basic shared hosting, upgrading alone can move the needle significantly.
