Pinterest will get into the advertising bandwagon in a big way and in time, don’t expect your promoted pins to appear without first paying them. Now Pinterest is a good spot to start curating interesting bits of photos and graphics for your business. People who follow you currently have to follow you to get an update on all your boards so that’s not a bad thing.
How the future will translate will depend on your budget. Integrating Pinterest to your online business is a good idea but only if you have set aside the required number of hours in a day to curate or create new pins for people to see.
