Descriptions and Titles
Pinterest is a SEO machine, between hash-tagging and appropriate descriptions of what you are pinning, can make a huge difference in who is going to be viewing them.
Be sure to include as much description as possible and about the pin itself.
If the image contains text, make sure to write word for word what that pin is saying as it will show a lot of workmanship behind your boards in the long run.
If you are using hashtags, be mindful of the content and always keep them in close relation, do not overload your descriptions because it can look spammy to some pin collecters.
In the case above, 5-6 Hashtags could prove to be sufficient but during tests I wanted to gauge activity of what was working so testing and finding what works for you is also important.
Getting a feel for these pieces of social media and thier capabilities wont only save you time and effort but it will also increase how fast and how many posts or pins you can achieve daily to keep your insights ramping up, without over doing it.
I signed up after reading your post this is going to be very helpful I will keep you updated on how it goes.
