A Facebook app developer might represent the difference between a successful social media campaign and an outdated fan page over Facebook. The truth is that anyone is free to start a fan page or perhaps a group too. Dealing with an application is harder though. At the same time, even if you only need a page, keep in mind that there are specific marketing strategies to consider. Otherwise, it is less likely to attract your audience in any given way.
The benefits of a social media agency are more diversified though. For example, you gain the possibility to upgrade the service to a more professional one. You may just as well downgrade it if you cannot face the new traffic. For instance, if your social media campaign has been effective in drawing extra traffic and attention, you might need a little more in order to push your limits. Or maybe the traffic stagnates, so you obviously do not need so many Facebook updates and posts. Although it is hard to tell the difference if you are not experienced, the general idea is that you can customize the service according to your personal needs.
The wide variety of connections are just as helpful in a social media campaign. After all, social media is about socialization, so such agencies obviously have plenty of connections across the web. No matter how insignificant they may seem, they will most likely work a very long way. In the end, it feels like your expenses have actually worked out positively.
