Fixing Core Web Vitals on a medical device manufacturer's website in Dublin: 2026 costs

The verdict in three sentences

A site with a 5.8 s mobile LCP loses rankings and contact requests, especially in a sector where hospital buyers check product pages on their phones. A Core Web Vitals audit costs EUR 1,200 to 2,500 excluding VAT and tells you whether EUR 3,000-8,000 of optimisation is enough or whether the theme forces a EUR 12,000-20,000 rebuild. The target is an LCP under 2.5 s and an INP under 200 ms, with an observed organic traffic gain of 15 to 30% within six months.

Diagnosis: where the 5.8 seconds come from

On medical device manufacturer websites, the same culprits appear: 2 to 4 MB JPEG product visuals, homepage carousels, demo videos loaded on arrival, and a pile of third-party scripts (chat, CRM, cookies, analytics, heatmaps). The WordPress or Drupal theme bought six years ago often adds 600 KB of unused CSS.

The audit measures these metrics on field data (CrUX report in Search Console) and in the lab (Lighthouse, WebPageTest), across the 10 to 20 key templates: home, product range, product page, documentation, contact.

Optimise or rebuild: decision grid and 2026 prices

The practical rule: if the audit shows that more than 50% of load time comes from the theme itself (CSS and JavaScript that cannot be removed without breaking the layout), optimisation will plateau around 3 s. In that case, a rebuild is more profitable over three years. A point specific to the medical sector: regulatory documents (IFUs, declarations of conformity) must stay accessible and versioned during the rebuild, which requires a rigorous redirect plan.

Mini case study

Ciara, marketing manager at a medical device manufacturer in Dublin, sees 4,200 organic visits a month and 35 documentation requests. The EUR 1,800 audit reveals a recent theme but 3 MB images and 32 third-party scripts. The optimisation package is priced at EUR 5,500. After six weeks, mobile LCP drops from 5.8 s to 2.2 s and INP from 340 to 160 ms. Over six months, organic traffic grows 22%, about 920 extra monthly visits, and documentation requests reach 43 a month. If one request in ten leads to a hospital group listing worth EUR 15,000 a year on average, 8 extra requests represent around EUR 12,000 of potential monthly revenue for a total investment of EUR 7,300.

FAQ

Do Core Web Vitals really affect Google rankings?

Yes, they are part of the page experience signals. Their weight is moderate compared to content, but at equal relevance a site under 2.5 s LCP ranks ahead, and mobile bounce rate often drops 10 to 20%.

How long before the effect shows in Search Console?

CrUX field data is calculated over a rolling 28 days. Expect 4 to 6 weeks after release for the report to turn green.

Can we keep our chat tool and CRM?

Yes, by loading them after user interaction or after 3 to 5 seconds. That delay often saves 100 to 150 ms of INP without losing data.

Is the audit credited if we go ahead with optimisation?

At Kolonell, 50% of the audit fee is credited against the optimisation package or rebuild if ordered within 60 days.

What annual budget keeps performance on track?

Monthly monitoring with alerts costs EUR 150 to 400 a month. Without it, new scripts and visuals often push LCP back up by 1 s within a year.
