I would like to add one more to the "7 Steps To Choose A Niche For Your Blog".
I would include
"how newsworthy is the topic"?. I say this because if you can find a topic that has ongoing media appeal, it can really help you with the overall promotion of your site for a relatively low cost.
For example, if you were marketing (I.e. turkey fryers), you may want to develop a
great article with photos on your website about the safe use of a turkey fryer. (You may want to get your local fire department involved in this for a demonstration. Be sure to bring your video camera to capture your own (
YouTube moment).
Once the article was done,
every year, a week before Thanksgiving and Christmas, I would distribute the press release letting the media know to caution people to the possible dangers and offering safety tips, photos and a video demonstration at your site.
It's a great way to get the media working on your behalf, get some great backlinks to the site and all of the resulting traffic.
And hey, you never know, CNN just might come calling.
