Most SEOs assume Link building to be the sole off page SEO work, but it involves more than links.
As of 2015 the most vibrant SEO strategies define Offpage as a process of building reputation, improving Brand Name, and creating external contents. Although the traditional process of link building is still alive it is no longer the most (at least not the only) important off-page SEO task.
To me a company (Business) should make sensible steps towards establishing, improving and maintaining its online reputation and branding efforts. Although links are still relevant and are crucial in SEO rankings, SEs are changing and the demand for online reputation is getting ever more important these days.
Top 5 off Page SEO Tasks:
1. Social Media
2. Reputation Management
3. Link Building
4. Branding
5. PR (Press Release)
