What do you think of the baclinking strategy?

Forget all that. Write some good well-written content targeting the low competition keywords. Make sure your site layout is good in terms of internal SEO. Add silo style posts (look up Yukon's strategy) to the site and bookmark them. Get a few good high pagerank links to all pages. Honestly, I'd forget about linkwheels, directories, .edus, .govs and profile links.

For the higher PR links try BMR, Press Releases, Extremely Selective Blog posts/ Edu/Gov comments (here, I'm talking about manual ones that you'd do yourself because you have some knowledge of the subject), contextual hp links.

If you're going to use fiverr - well, what can I say. It comes through experience. Don't let the vendors "add extras" where they'll blast your pages on some ****ty software. The best gigs I've found that actually work at Fiverr are manual bookmarking gigs. There's a girl team that will do great manual submissions for BMarking, Videos and Articles and they are to limited services that work and have shown results. It's all alearning game and I wish you luck!

Hmmm this strategy is good but seems not much satisfying.I watched out that you haven't mention about contents anywhere.You should keep in mind that "content is king". First fill you site with quality contents then only do SEO stuffs.

What do you think of your title?
New website ? I think you should focus seo onpage first.

You'll need hundred of pages. Google is about content - and good content. Focus on that...

Pagerank all matters for quality. But with that it is also matters for the high conversion rate & less bounce rate, more inbound links & less outbound links, and quality content. Though you do not have more backlinks but yet due to the quality content you can get high pagerank for your site. So you can use article and blog method to display on your site and also make use of social media with these methods to get more engagement of people to your site.
