Idea pins is type of content format on Pinterest. They feel similar to Instagram Stories, but they don’t expire and are searchable. That means your idea pins will be discovered months after you’ve created them!
The power of idea pins is that it’s a way for you to create evergreen content on Pinterest without the need for a blog, a website or a YouTube channel.
Sweat, isn’t it? They are a fantastic way to showcase the products and services of your affiliate marketing on Pinterest.
However, idea pins don’t provide the ability to include links in the idea pin. “Oh no!” you might be thinking. Exactly, you and many are thinking exactly the same.
Don’t worry! Pinterest tags are here to help you be successful making money with affiliate marketing on Pinterest!
You can tag idea pins using affiliate links so that you earn a commission when people click through and buy.
Exactly, you can use idea pins to tag affiliate products.
However, this is only possible with specific affiliate programs and not all. So you might find that you can’t tag your product on idea pins. It’s still worth trying and absolutely worth creating idea pins as value content about your affiliate programs.
At the time of writing, affiliate networks and programs like Amazon Associates, ShopStyle Collective, and Rakuten Advertising are supported for affiliate marketing on Pinterest idea pins. However, please remember that not all affiliate programs are supported at this time and that Pinterest is working on expanding that list.
Please note that Pinterest isn’t part of affiliate agreements, so your commission will depend on the terms you’ve set with external merchants or programmes.
Finally, you can also use paid advertising on Pinterest to promote your pins. This can be done through Promoted Pins, ads that look and function just like regular pins but are shown to a broader audience.
