Spend some time working out what those long tail keywords are.
Try and come up with a list of 30-50 using Google Adword Planner, YouTube keyword tool and whatever else you consider relevant (Quora, Yahoo answers, forums, kindle books)
Once you’ve gathered a list of 30+ – begin creating natural content around those keywords.
Write quality content.
Find other people/blogs/influencer’s to reach out to to see if you’ll get a share or a mention.
Repeat this SEO strategy with each long tail keyword – one of them will work for you at building quality traffic to your blog
