In this English Google Webmaster Central office-hours hangout, John Mueller and other experts address various concerns regarding rel=canonical, website ranking, Penguin algorithm, technical foundation, content diversity, moderated comments, hidden content, and social media promotion. The analysts emphasize the importance of having a solid technical foundation, creating a fantastic website, and finding a niche market to rank a new website in an established market. The discussion also covers the impact of hidden content behind tabs on a website's search ranking and the promotion of clients' products or services on different social media sites.
During the English Google Webmaster Central office-hours hangout, John Mueller advises against immediately switching to responsive design if a website already has a separate mobile domain, but acknowledges that having everything on one version of a site helps avoid potential problems. He also recommends differentiating between reversed IP lookup domain names and the main content website for hosting companies with subdomains, redirecting IP addresses to the actual website, and not nofollowing links inside the HTML header since there is no provision for it. In terms of comments, there is no safe number, rather, the overall quality of the page is considered.
