Great question! The difference is (IMO) that a press release should be a "news-worthy" article e.g. XYZ company just released a new gadget, and it will go on sale in selected stores on this date ...Quote:
What is Basic difference press release and article marketing...
This is very different to spamming press release sites with a random article.
Get the idea?
This finally gives me a chance to get this gripe off my chest where I see so many SEO guides recommending press releases as step n in the process (but most of us will not have news-worthy content to post as a press release unless we created something new).
