Core Web Vitals Fix

Measure, fix, then prove it moved

Core Web Vitals are three measurements of how a page feels to use. Largest Contentful Paint asks how long before the main content appears. Cumulative Layout Shift asks whether things jump around while loading, which is what makes people tap the wrong link. Interaction to Next Paint asks how long the page takes to respond after someone touches it. Google reports all three from real visitors, not from a laboratory test, which is why a site can score well in a synthetic tool and still fail in the field.

The engagement starts with profiling. We work from your field data where it is available and from traced page loads where it is not, and identify the specific causes rather than the symptoms: render-blocking resources, unsized images, fonts loading late and reflowing the text, third-party scripts blocking the main thread, layout shifts caused by advertising or consent banners injected after paint.

You then get a fix plan, prioritised by the size of the improvement against the effort to implement. We carry out the work, including image handling and lazy loading, and check accessibility alongside it, since focus order, contrast and tap target size are part of usable mobile pages and are usually cheap to correct while the templates are already open. Finally we re-measure and hand over a before-and-after report so the improvement is documented rather than asserted.
