Press Releases
These days most press releases are issued online. These are important in increasing your digital footprint on the web.
You should issue all of your press releases on your own website. This provides you with additional content but also shows your potential customers your recent activity. You should also make this available via an RSS news feed.
You should find out where press releases are issued and consolidated online for your industry, and the leading journals and websites that provides news updates. You should send these organisations copies of your news releases.
You can also issue press releases online through some of the very many news sites. Most news sites have a free submission service. Make sure you include links back to your site, often this is in an About You part of the form submission.
Start with sites such as PR News but search for your competitors and see where they post releases.
