ISOWQ performs a detailed analysis of HTML code, meta tags, graphics and multimedia files, and social network applications. When analysing HTML code it retrieves information about the author from the "author" meta tag, copyright details from the "copyright" meta tag, and the program/system that was used to build the website from the "generator" meta tag. Text and graphic elements also play a part. Text content is one of the most important elements of a page, being often the main purpose for creating a website. ISOWQ searches fo appropriate keywords and determines the most optimal ones.
