As the name suggest Pinterest has to do with what interests you. It gives its users an avenue to upload and add what they are interested in. If you are a fan of football, then you can add what interests you there and if someone else has a similar interest, they can do one of these three things; they can like what you have posted, they can comment on it or alternatively they can re-pin it. Re-pinning in the context of Pinterest means that they upload the same thing you had. This means that they get to have friends on their pages get to see what you had pinned.
Marketing in the context of business means getting your target group get to know about what you are offering; it has to do with getting the services of what your business does to the right people. Chances are that if your target group gets to know about the services you are offering then they will get to look for them. When they do, you are guaranteed to make a sale. Essentially, this is what you are looking for when you go out marketing the services you are offering.
Pinterest aids in marketing because of the fact that it gets people to see what you are offering. There are various categories that you can choose to have your services advertised. What Pinterest does is give you an opportunity not only to organize what you are offering, but also share it to the people who want to see it. That is the reason why there are categories so that you can clearly get the target group that you are seeking. People will go the categories that interest them after which they will get to have the information they are seeking. Pinterest gives you the opportunity to have pictures of what you are offering. A well documented picture carries a heavier message than written words. It is also much easier to remember a picture you saw than the message you read. You also have the chance to write anything you want about the services you are giving. Perhaps you may have just launched a new product; you can have the photos taken and upload them in Pinterest.
When it comes to public relations, Pinterest contributes immensely to the way a person who may well be a potential client reacts to your business. Public relations deal with the image that you create to the public. As a business you need to have good public relations in order for clients to not only trust you but want to do with business with you again. Pinterest comes in to convince clients that you can deliver on what you say. This happens through the opportunity to get to comment on your pin, like it or re-pin it. This gives potential clients the confidence that you can be trusted as a result of the number of likes, comments and re-pins that you have.
