When we review websites for medical device and life sciences companies, one problem comes up almost every time: the mobile site is poorly optimised.

And it's more important than you might think. In an era where we (and our target customers) are increasingly finding solutions through generative AI tools like ChatGPT, Perplexity, and Google Gemini, a slow or unstable mobile site can mean your product never appears as part of the answer.

Why Mobile Sites Matter to AI Tools

Generative AI tools only index the mobile version of your site. That means your mobile site IS your website when content is discovered, indexed, and evaluated. Even if your desktop site is flawless, AI may be working with an incomplete or poorly performing version of your product information — making it far less likely to recommend you.

Checking if Your Mobile Site Is Hurting AI Visibility

You can quickly see how your mobile site performs using free tools:

• Google PageSpeed Insights (pagespeed.web.dev) - just pop in your website address. You can check competitors, too.
• Core Web Vitals Guide (web.dev/vitals) - this explains the insights well
• Google Search Console – Mobile Usability Report - Google Search Console is a great source of information for many aspects of website health
  

Why Fixing Mobile First Is Critical for Product Visibility

Too many medtech companies launch a site that looks perfect on desktop but is awkward or sluggish on mobile. In the GenAI context, this means:

• AI tools may never surface your product because your mobile site sends poor usability signals.
• Competitors with faster, cleaner mobile experiences become the default “trusted” sources.
• In time-sensitive product categories, missing those first impressions means losing market share.

If you want your product to be the one AI tools recommend, mobile performance is critical. Because if your mobile site is underperforming, the real risk isn’t that your site goes unseen, it’s that your product becomes invisible.
