I am often asked why press releases are important. In my experience, they are a fantastic (and affordable) opportunity to shout your business news to the world. There's no guarantee that the news will get picked up by the media - that's a blog post for another day - nonetheless, you can increase your exposure online and with your customers.
Some reasons for a press release:
Business launch or anniversary
New product or service launch
Nonprofit work or donations
Remodeling or expansion
Significant earnings or growth announcements
Have you issued a press release lately? If not, add this to your marketing plan for 2009.
