You'll learn the theory behind Google search and other search engine algorithms; you'll also build practical, real-world skills that you can apply to a career in digital marketing or online content development, including on-page and off-page optimization, optimizing for local and international audiences, conducting search-focused website audits, and aligning SEO with overall business strategies. Each course is intended to build on the skills from the previous course, thus we recommend you take the courses in the order they are listed. The Specialization culminates in a hands-on Capstone Project, in which you will apply your skills to a comprehensive SEO consulting task.
The world is mobile today. Most people are searching on Google using a mobile device. The desktop version of a site might be difficult to view and use on a mobile device. As a result, having a mobile ready site is critical to your online presence. In fact, starting in late 2016, Google has begun experiments to primarily use the mobile version of a site's content42 for ranking, parsing structured data, and generating snippets.

Having a ‘keyword rich’ domain name may lead to closer scrutiny from Google. According to Moz, Google has “de-prioritized sites with keyword-rich domains that aren’t otherwise high-quality. Having a keyword in your domain can still be beneficial, but it can also lead to closer scrutiny and a possible negative ranking effect from search engines—so tread carefully.”

Hey Sharon, great post! Re. dwell time – I’ve read conflicting opinions, some saying that Google DOES consider it an ‘important’ ranking signal, and others saying that it doesn’t, because dwell time can sometimes be a misleading indicator of content quality. For example when a user searches for something specific and finds the answer immediately in the recommended page (meaning that the content on the page is actually spot on) so he returns to the SERPs very quickly. I have been unable to locate any definitive statements (written/spoken) from anyone at Google that suggest that dwell time IS still a factor in ranking considerations, but it makes sense (to me, anyway) that it should be. Do you have any ‘proof’ one way or the other re. whether Google definitely considers dwell time or not?
