Best way to build backlinks to rank high in Google?

Start from Q&A Sites like Quora to get your site before the world. Post your links on reddit, Pinterest & facebook groups (Do Not Spam. Go Slow on these sites). This will help you get initial boost of traffic, Then start creating Web 2.0 links, Blog Commenting, Press Releases, Forum Profile links, Contextual links (guest posting and PBNs if you have enough budget). But again, Do not build links rapidly. Go Slow and steady. Overtime, You will start seeing results and your keywords will start ranking on google's 1st page
