When you save a Pin on Pinterest, we distribute it to your followers FIRST. DISTRIBUTING to followers first allows Pinterest to gauge your followers’ interaction and decide which Pins will be popular.
The following tab allows us to get our content in front of our audience much SOONER than before. This helps Pinterest rank our Pins for future DISTRIBUTION.
So, ironically, the first step to SEO (search engine optimization) on Pinterest is to make sure your content will resonate with your followers, because they’ll see it first. Make sure it’s engaging.
The next factor is using APPROPRIATE keywords so the Pin can be identified as relevant to others who would be interested in it.
