I notice this typical error with new customers and other pinners on Pinterest.
Creating keyword-rich board descriptions can help people locate your pins. Pinterest is akin to a search engine like Google; therefore, you’ll want to optimize your boards and pins to show up when people search for them. Like SEO’ing your blog content, you want to SEO your Pinterest account!
Use Pinterest to study the finest keywords for your boards. Type subjects into the search box and see what comes up. Those are the precise terms pinners are using to locate what they need. You want to utilize those same terms in your board descriptions.
