One of the most important things you need to consider is page content. The best thing to do is to provide your audience something of value, for instance, offering more than just information about your business.
Variety is key. Start by posting content regarding the various ways your business can benefit them. Build upon that by telling them about how your business stands out from others who offer the same services. Keep your content interesting and different. This will prevent your audience from getting bored with your posts.
Post Pictures Along With Content
Never put out multiple posts at once. Many people do this in an effort to provide variety and a multitude of content. Generally, you should let a few hours pass between your posts to avoid bombarding your audience.
The minimum time after which you should post fresh content is 45 minutes. If it's not urgent, it can wait. Fans are more likely to block your newsfeed when posts show up in feeds constantly because it appears to be spam.
So remember this rule of thumb: post new content, allow AT LEAST 45 minutes to an hour to pass, then post again. You will know you are posting too much when you make more than three consecutive posts in an hour.
