what are the right circumstances to ue a press release service?
is it a publicising machine like an article directory?
what are seo features?
There are many circumstances unto which you will want to use a press release:
your business is expanding
a major sale
new product or service
new important staff
community service
or just about anything else newsworthy.
We go out of our way only to publish original press releases. Those submitting your 'press release' to article directories are not really doing a press release and any savvy news person will catch on to that. And besides - duplicate content is useless these days. Don't cheapen your efforts by delving into article directories as a way to make good press.
Use one - maybe two services at most. Members of the press contact us often to be added to the list and once on often remark that they appreciate us filtering out all the duplicates - their time is valuable! By keeping them happy we maximize our service all the way around.
Google news is the biggest online source using our feed. In turn their feed is displayed or otherwise scraped by hundreds of thousands of other websites. Your press release can be accessed on hundreds of websites in just minutes! (depending on niche etc) As well, google on many searches will put news results as the top result - so your press release can be not only on google news - it can be the top result of hard to target keywords!
You can use backlinks (though we do use nofollow) in your press release for general usage and SEO purposes. But more than that, you get positive news on the Internet about your company/product/service etc.
