BusinessWire is my pick as well, for the same reason.
Can press releases garner more web traffic? Definitely. How?
- You'll need a couple (not a lot) of carefully chosen, targeted keywords interspersed throughout your press release, and these words are the ones to be used to link back to your site.
- However you decide to promote your press release, you need to make sure the sites you are submitting to (a) are already highly ranked, (b) will link back to your site in exactly the way you've specified in your press release and (c) have a large amount of traffic that will expose your press release, company or message to new readers.
- Write about something that is actually newsworthy. Sure, your company may be 25 years old. But the question is (not to seem callous): why do I care? Making the reader care is the goal.
Writing press releases and submitting them to the freebie submission sites and/or creating your own media list is an extremely inexpensive way to get more bang for your online marketing buck.
I've written an article about free press release submission if anyone is interested. Unfortunately I cannot reprint the article here but here's the link:
