See image below with our company website being pinned from. I selected our logo (just for this demo) and text, which you can see highlighted on the website itself. The Pinterest window then pops up and you can now see the text included.
NOTE: Hash tags (#) apply in the Pinterest environment. Add a hash tag before key words (no spaces) to increase it's searchability.
