The way I use this social networking site will be different from the way you use it. You have to just test things out and find out what works best for you.
You can use Pinterest as a promotional tool and build your brand. You can use it as a research tool because you will be able to get an idea of what your target market is interested in.
This will allow you to take advantage of this information to effectively position your business to the right people.
If you are a blogger, make sure you include captivating images with your most valuable content.
Pin it to a specific board that will lead people back to your blog.
Keep in mind that you are using Pinterest as a way to build relationships with a totally new audience.
It is not about you or constant self promotion.
Create boards that give excellent recommendations to other people in your industry. Re-pin, comment, and like other people’s content on Pinterest.
Follow the pinned boards of the people you admire. This lets your audience know that you are a valuable resource for them and the people you recommend will notice your efforts.
