Sources and method

This page states where every figure shown on web-consulting.fr comes from. Performance measurements are taken with Lighthouse 13.4.1 on the homepage, mobile profile then desktop, on 26 August 2026. The exact commands are given below: anyone can repeat the measurement and get the same result, network variability aside. The published page count is the number of loc tags in the XML sitemap, checked automatically on every publication — if the displayed figure diverges from the real sitemap, the release fails.

What we quote from third parties

What we do not claim

For symmetry, here is what these figures do not say.

  • Lighthouse scores are lab measurements on a simulated connection. They do not replace CrUX field data, which web-consulting.fr does not yet have enough traffic to feed.
  • The accessibility score is automated: it covers only part of the RGAA criteria. See the accessibility statement.
  • The portfolio count includes demonstrations, labelled as such on each page. They are not client commissions.
  • No traffic, conversion or average-position figure is displayed on this site: we do not yet have a long enough series for them to mean anything.
