I launched a new website 3 weeks ago (05/01/16) a product review site with supporting niche blog articles. I've published 6 reviews articles (8000 words total) and 7 blog posts (7000 words total). This is my 2nd website, my other site is a travel blog. I'm using my travel blog social media channels, renaned and added my niche site url to them. I've added Tumblr and Hubpages, posted some content there and done some blog commenting. I'm getting some Google traffic and 1 sale so far, Google traffic is about 10 unique hits per day. I've been using Webmaster tools and checking rankings by looking at the search analytics, my main two keywords for 2 of the review posts are position 173, but long tail keywords are from 10 to 50. I haven't done much link building, should I use something GSA SER or white hat SEO link building? I think I done the keyword research ok, been using Long Tail Pro.
