There are many variations that you can try while creating a link baiting blog article, but if you want to concentrate only on time-tested methods, I would recommend that you simply include something controversial in your blog article.
Everyone loves a bit of controversy in their lives and if you manage to include something controversial in your blog without ruffling too many feathers, you can rest assured that your blog will be a big hit amongst online users and you will get the desired number of back links for your website.
