Build a good social network, use IFTTT, SNAP, Massplanner, hootsuite, what or a combination, but build good social engagement.
Also use SNAP and/or IFTTT to post to some branded web2.0s, build a strong brand through syndication.
Do a blast of single page web 2.0s, GSA, cheapy PBNs, etc... To your branded web2.0s.
Find relevant things you can post out there, PDfs, slideshows, videos, audio files. Make an account on a platform, build up that account with 2-6 quality uploads, then move onto the next platform. Aim for 5 channels minimum, and share the content on your site.
Do a blast of single page web2s.0s to those channels, maybe a GSA blast.
Now, build up(or buy) 10 web2.0s(different platforms) and make them quality, multi-page, all the standard pages, strong inter-linking.
Buy some blog comments to those, maybe a blast of single page web2.0s, perhaps even a blast of cheapy PBN posts. Point those web2.0s to your $ite.
Make some niche relevant blog comments, get active on some niche relevant forums and offer helpful advice(meathead method).
Now guage where you fall on the serps, and readjust your building.
Maybe make some good web2.0s, and give them a blast of quality PBNs(buffer), make a few guest posts on real sites, and keep working.
