One question that people often ask about writing blogs and news for their website is whether they should link their articles to other articles on the website. Does Google follow the links that you put in your own articles, even though you’re linking to other articles on your site?
The answer is of course yes. Google follows links on every page of every website on the Internet. The more pages that link to a specific page, the more important that page is considered. Therefore if you have a post about something that you feel is a particularly good one, the by writing another post and linking back to your original post will really help that first post in the Google rankings.
Each post you write that links to it acts as a vote, so the more posts you write linking to it the better your original post will feature in the SERPs.
