SMM refers to both organic and paid digital marketing efforts on social media networks like Facebook, Twitter, and LinkedIn. Social media marketing encompasses many different activities and many consider this to be the future of digital marketing. While social media channels become the hub of activity online in the modern age, this is where consumers engage each other in conversation. Furthermore, it’s also the nerve center of business and brand engagement for large subsets of the population.
I would say that it definitely depends on the niche that you’re in. If your niche is quite small, then it’s probably easier for you to rank for your mid-tail keywords and you should definitely give it a go! Otherwise, it might be better to start with your long-tail keywords and work your way up to mid-tail keywords and eventually your head keywords. So, I’d say: analyse your competition, see where you stand and establish your game plan! Good luck Naved :)!
Ask for a technical and search audit for your site to learn what they think needs to be done, why, and what the expected outcome should be. You'll probably have to pay for this. You will probably have to give them read-only access to your site on Search Console. (At this stage, don't grant them write access.) Your prospective SEO should be able to give you realistic estimates of improvement, and an estimate of the work involved. If they guarantee you that their changes will give you first place in search results, find someone else.
