It's possible to earn positive recognition for your brand without the help of an agency, but it is a difficult and time-consuming task. Especially if you consider how frequently social media platforms release new tools and features. It's best to let an agency with trained professionals handle this work for you.
Targeting Multiple Networks
It's very likely that you are part of the large percentage of people that already has a social media account. If you can manage your own account, then couldn't you manage a business account? What if you had an account on Google+, Twitter, LinkedIn, Facebook, Instagram, Twitter, Flickr, and Pinterest. And then what if you were expected to post on them every day and actively engage with your followers.
How much time would that consume? The answer is, " a lot". One of the biggest benefits of working with a social media marketing agency is that they can tackle all of the major social media platforms at one time. That's saving you hundreds of hours of work. They can manage this seemingly impossible task because they put the work on a full team of people rather than just one person.
