How to Get Quality Back link in 2015?

[BrettUK]

While building backlinks, quality is requisite but you should not overlook relevancy. Google gives more weightage to links which comes from a high authority and relevant website. I would advise you to monitor your competitor backlinks. You will certainly get some good ones.

You should also keep in mind that keyword rankings does not solely depend on backlinks.

I agree with above, it's also good to search your brand name and see which websites have mentioned you but haven't linked your site.
Good chance to get in touch with the webmaster to see if you can get a link.

If you want to boost your ranking in SERPs you need to get good quality links from other authority sites. Review top companies & products and they might link back to you.
