Content Rule: 80 Percent Value, 20 Percent Advertising
If your content is 100% advertising, you will lose your page's fans. In this case, you may reach 20% of your goals at best, and your page won't be followed more than that amount.
Follow the Pareto principle; that is, 80% of the content you provide must be dedicated to the topics pertinent to the business, and 20% must be advertisement. For instance, it is not cool for a restauranter to keep complimenting his/her restaurant and advertise it.
If you own a large company, you should avoid publishing gossips and tabloids. However, small companies can try this method on a temporarily basis.
Content must be appealing and creative but pertinent to your business.
Assume that your business is running a restaurant. If your restaurant has an interesting kitchen, use that place for your benefit and report what happens behind the scenes. Report what happens there constantly and provide contents by shooting videos and taking photos.
We had a cooking show and instead of shooting the show in a studio kitchen, we would go to big and famous restaurants.
This content was much more interesting than bringing the kitchen to the studio and shoot the show there.
