I have collected the top popular job offers that go to SMMs - and they, as a rule, do not do this kind of work. Most often they offer the following tasks:

- Email newsletter
- Articles on the site, work with SEO
- Website development
- Contextual advertising
- Working with review sites

All of the above falls into a larger category - internet marketing. And there are comprehensive services that internet marketers do. In this case, they can combine both SMM and other functionality from this list.
