Increasing sales.

[Harris Smith]

I have a small automobile shop in Toronto and were getting good business for last few years. But suddenly for last three months, the business is going down the drain. I don't know what to do. I am really struggling to make more sales. I think I need to go for some promotions. I would like to run an advertising campaign that can help customers to know about my services and they can buy through online. But I'm not sure how can I make one on my own. While searching online I found few blogs. But apart from this, I need something more practical.

Please help me with few tips. 

Here are those blogs: http://www.socialmediaexaminer.com/create-an-effective-facebook-ad-campaign/
