Using Press Release for SEO

One SEO technique I also use is doing a press release. A Press release creates a good quality backlink from the news agency to your website. There is a great deal of link quality from news sites because of the "trust factor".
Apart from the backlink, you also get the much needed exposure. These news agencies has RSS feeds that gets your press release to many websites quickly and you get instant visitors from people who read it.
Here are some ideas when to do Press Releases.
1. When you launch your website
2. When introducing a new product
3. When you get an award
4. When you win a contest
5. When you move location
6. When you close a new contract or a big sale
7. When your sales are above target
8. When you get certified by a government or any 3rd party agency
