While most of the links to your site will be added gradually, as people discover your content through search or other ways and link to it, Google understands that you'd like to let others know about the hard work you've put into your content. Effectively promoting your new content will lead to faster discovery by those who are interested in the same subject. As with most points covered in this document, taking these recommendations to an extreme could actually harm the reputation of your site.
Sending out regular newsletters and promoting offers through email is a great way to stay in touch with your customers and can also help to get traffic to your website. Provide useful information and links to pages on your website where they can learn more, such as through blog posts and landing pages for particular offers. Just make sure that you don`t continually bombard your readers with emails or your customers will either disengage with, delete, or unsubscribe from your emails.
