Facebook only allows application tabs on Facebook pages, not personal profiles, so you can only add your social store to your facebook page.
There are many benefits to having a business Facebook page, here are a few of them:
1. It’s visible to all! While your Facebook profile can only be seen by your Facebook friends, everyone can see your Facebook page, which is great for business (...)
2. No limit! In your Facebook profile you are also limited to 5,000 friends, but in your Facebook page there is no limit on the number of fans you can acquire.
3. Since your Facebook page has no privacy restrictions, it can be indexed by search engines and be visible in search results. This means that potential buyers can find your Facebook page by searching for it, just like a business website.
4. Promote it! You can promote your facebook page in many ways and find new potential customers this way, read this article to find out How to Promote Your Facebook Page and Get More “Likes”.
