Some other ways to get backlinks to your website:

* Get an account on Helpareporter. This is a place where the journalists or reporters are looking for queries for their articles. You can answer them if it falls in your area of expertise. If approved there is a chance of being featured in high domain authority sites like the New York Times, Business Insider, etc.

* If you are into creating youtube videos, podcasts, mini multimedia posts, etc, they are also other excellent ways to create backlinks from them.

* Do not ignore internal links in your post, they are important as well. Link them efficiently. If the internal links point to a certain post or page, many times it signifies as it being important. The search engines crawl and this, in turn, helps improve the navigation and finding of content on your site. It also plays a huge role in page ranking.
