I have seen that most bloggers are using "read more" as link text to posts on their home page that link to the full article or blog post. I understand that it's quite important for navigation of site. But when you see Google's official blog or other blogs of Google, they do not use the "read more" link on home page of blog.
So is "read more" as a link good for SEO or bad because Google itself is not using these links. Can anyone throw lights on this?
