Core Web Vitals in telecommunications: 105 domains measured
By Christian Schreiber · Updated
Providers who sell speed are judged on the speed of their own website, and visitors draw that conclusion immediately. At the same time these sites carry extensive tariff and availability logic.
For Core Web Vitals, telecommunications ranks last of 18 industries, behind travel and hospitality. Its weakest metric is INP: the industry median of 234 ms is above Google's threshold of 200 ms.

What usually slows telecommunications down
Availability checks and tariff configurators are substantial applications that often load on every page. Device imagery at high resolution on tariff overviews adds to it. Deferring the availability flow and serving responsive sizes for the device imagery resolves the larger part.
Which telecommunications pages to test first
Tariff overviews, device pages and the availability check carry the commercial traffic. Test a tariff overview with device images, a single device page and the address check with an address entered. Shop and self-service areas often run on separate platforms, so test them on their own instead of assuming the home page values apply.
Which metric is at risk in telecommunications
INP is the metric most at risk, because availability checks and configurators react to every input and bring large scripts. LCP suffers from high-resolution device renderings at the top of tariff pages. Layout shifts appear when promotional banners and price badges are inserted after the tariff grid.
