Hi Brandon,
If the company has something to announce, something interesting (not a website update) then yes this is a good way to build some links. My favorite is charities they are an easy win win. You help by donating time/money to a good cause. Attend a reliable charity event and network with everyone there, get the name of the person who organized the event. Call the event organizer and tell them you had a great time and you are preparing a PR on the event. They are usually extremely happy to hear that.
Once you receive the list contact everyone and offer them to leave a quote with a link to their site on the PR. Also let them know that after the PR goes out to share it with their social media.
Syndicate the PR to your own blog and have the share that link ; )
This is where everyone shared the article from:
