Technical SEO: from HTML Tags to URL

The technical aspect of SEO takes place in several steps and consists of the crawl of the site, indexing of web pages, the loading time of the pages, the internal linking and the structure of the site. In this chapter, the authors focus on the technical part and they concern the tagging of HTML pages. The authors explain how many URLs comply with the rules of search engines of all types (Google, Baidu, Yandex, Naver, Yahoo! Japan, etc.). At this stage of the audit, the authors investigate why these URLs do not comply with Google, Baidu, Yandex and guidelines. To optimize page loading times, the authors also audit page types to ensure that all pages on the site are fast enough on the Web.
