Advertising disguised as content always works best. Advertorial it's called. You're not tricking people into working with you, you're educating them.

Always use a problem then discuss solutions to this problem and make sure you're one of the solutions. Make sure you have more than one solution or you will come off as spam and make sure that it's a well thought out piece of content.

Content just for content sake is noise. I would rather see you produce one blog post, video, image message a month that is great then 1 a week that is mediocre.

Editorial Calendar is crucial to this process, it will help you plan out exactly what message you want to get across (the problem you're addressing), what medium to use to best demonstrate this message (blog post, image, video), the solution and of course where and when it should be posted.

Good luck.
