Necessity
If you are just starting out, a weekly upload or pin will not be enough at all. You need to work overtime during the first few days and get your Pinterest page bursting in the seams and appear jam packed with relevant and interesting information and stories to share through your pins and repins.
Ultimately, it’s about necessity. Be extra aware of what’s going around you and pin or repin more photos if the situation calls for it.
Take the holidays for example. Christmas typically demands a higher output because this is the time where people are in the mood to buy. You need to take advantage of that and increased activity in Pinterest will surely increase your chances of capturing your market’s attention.
