Voici un site qui mesure la qualité des sites web à partir de différents critères. Sitescore est assez intéressant car il ne se contente pas seulement de parser et valider le HTML, il mesure aussi le référencement, les temps de chargements, l'accessibilité, ...

Marketing How well marketed, and popular the website is. Is the website well linked to? Does it feature highly in key search engines, for relevant terms? Design How well designed and built the website is. We test for various industry standard practices, and whether they were used correctly on the website (for example: use of frames, style sheets, redirections etc) Accessibility How accessible the website is, particularly to those with disabilities. Recent UK and US government legislation makes this a legal requirement in many countries, which we test against. Experience How satisfying the website is likely to be. We test various things, such as the speed of your website, the amount of variation between webpages, the number of clicks required to navigate between one page and another. User Average user feedback, gathered from people rating the websites in our list. Users are asked to rate how a website looks, on a scale of 1-10. This is the only non-automatic test, and as a result it can take some time for a website to gather enough votes to score here.

Le service semble être mis à jour régulièrement mais est malheureusement uniquement en anglais ce qui perturbe le résultat pour les sites français.
