Link text is the visible text inside a link. This text tells users and Google something about the page you're linking to. Links on your page may be internal—pointing to other pages on your site—or external—leading to content on other sites. In either of these cases, the better your anchor text is, the easier it is for users to navigate and for Google to understand what the page you're linking to is about.
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?
