What is W3C HTML Validator

Due to the unceasing growth of web sites and applications, developers and evaluators have interesting challenges not only from the development but also from the quality assurance point of view. The quality assurance was and is one of the challenging processes in software engineering as well as for the web engineering, as a new discipline. Although there exist many design guidelines, and metrics for the evaluation of web sites and applications, most of them lack a well-defined specification framework and even worse a strategy for consultation and reuse. The main theme of the research paper is to provide optimization techniques to improve the correctness of the website.
