Just as visuals are important; keywords also play a huge role in pushing your Pins and showing them to relevant searches. Here’s where you should place your keywords
To attract the right audience, you really need to have a strong bio with all the keywords you’re targeting to rank for
1. Profile
2. Pin description. Pinterest allows 500 characters for Pin description and this is your space to play around and embed the best keywords. However, make sure that you just don’t stuff your keywords without any sense. Your Pin descriptions are read by people so make it seem natural
So yes, Pinterest can actually read your Pin image, and having a keyword on beautifully curated Pin can definitely attract more readers. Hence, be sure to use keywords while creating the Pins.
Now instead of saving the file name as image.jpg, save it using a keyword like journaling.jpg or whatever your keyword is. This will make Pinterest understand what the image is all about.
