Is there the best time to publish the pins? I always post in my spare time, but I see that there are articles to be published at the right time. Does anyone understand this?
Yes there is 🙂
But it is not the same for everyone - do you have a website with google analytics tracking visitors?
In that case you can check google analytics and see what time of the day people are most active on your website and start pinning around those times 🙂
Another way to see what times are best tailored to your account is tailwind - you can sign up and get 100 pins for free and their smart schedule will show you the times that work best 🙂
