So, I have a website targeting a weight loss keyword. A few months back I blasted this site with scrapebox, I don't remember how big the list was but Yahoo is currently showing over 4k backlinks. Just a couple weeks ago I noticed it was ranking between #12 - #15 on G, so I took an article and ran that through AMR, ALN, and AR. Now just this morning I ran MS rank tracker as I usually do and my site is sitting at #8 on page 1! Also this site is using WP Robot so NOT 1 piece of unique content on the site.
