I can understand and appreciate your enthusiasm if you are new to this but if you read through some of the current threads in the google forum here you might be able to understand that now is not the best of times to be seeking advice for ranking a product -- it strikes a raw nerve.
Other than that if your competition is nil as you say then you shouldn't need to write any blog stuff. Just having the words in your product pages and a short write-up about them there should be enough to send you off to the races *sigh*.
Nobody can predict how successful you will be or how long any success might take. This is because there is so much uncertainty about the various factors involved in your particular case, as well as uncertainty about the details of how Google's ranking algorithm works.
It's certain that the best backlinking strategy these days is to go VERY light in what links you arrange - if in fact you arrange any links at all. Google is all over backlinks that they think were created rather than those that they see as "natural", and at a certain point, you're very likely to trash any rankings you had going.
If you can find a good directory on your topic, that would be one place to try. And possibly just one or two other spots. If the competition is really low, then that should do it.
If those exact match searches are long phrases (it sounds like they might be) you still might be outranked by sites that don't include all the words but have been established longer. And I completely agree that you will need some good quality content. Otherwise, the Panda may well give your new site a big bear hug too.
@lewis1 Yes I understand your point. But I think it depends on the type of website. My main sites are about controversial social issues, and for that reason they do regularly pick up "natural" backlinks without any involvement on my part, because people are interested in the issues they cover. But a site about a common "run of the mill" product, as in your example, probably won't attract many natural backlinks, even if it's an informative high quality website.
I think this is a good example of the types of complicated distinctions that the Google algorithm has to deal with.
It's been a LONG time since I've seen a phrase that has literally no competition. These days Google is very good at mixing in images, youtube, news, irrelevant results etc. whenever they feel they don't have enough results to completely fill up page 1.
If you really are up against literally nothing, then simply having the phrase in the title or an H1 tag or even anywhere on that page for that matter, is usually enough. Just wait for G to crawl it. I've seen blog posts indexed and ranking in less than one hour after they've been posted. So, I don't understand why you are looking for some clever strategy. Sounds like simply writing about the subject and using the keywords somewhere on the page should be enough.
I;ve been looking for the answer to same question for last 2 years,
true story: Found low competion keywords bought keyword domain, almost emd optimised and put a little content spent 1st year been out ranked by 5th level pages on major sites, a couple of parked premium emds, assortment of of other site which barely mentioned the keywords 2nd year , finally got to page 2 :)
okay, I'm not the sharpest knife in the SEO cupboard, but for a while I've been thinking that Google has been enforcing the status quo
new entrants probably need more resources than they used to before 2010
