I have backlinks for my business from really reputable blogs that I sent free products to. However, they aren't showing up! Some links show up in a couple days, but not the ones I want! (high quality ones) How long do they take to appear? Majestic SEO isn't seeing them, neither is webmaster tools. Please halp. These links went up about a week ago! I pinged them and all that jazz. Still nothing. I'm not very good at SEO - I use all paid and social traffic. But I want to increase sales from the search engines.
