Review : I've got a silver package review copy from OP. I gave him a URL of an article of mine with 3 keywords 1 main + 2 variations. Results : The links from the package itself are very basics and not so great quality : PBN posts on multi-niche pbn with quite off-topic text, no images, and random anchor placement expired tumblr with links put "as-is" so it is replaced by tumblr redirection -> no link juice web 2.0 with only one post, no image except for profile picture some social shares, profile links, article submission, social bookmarks, photo sharing tier 2 urls are on url submit site (Pligg CMS & co.) Conclusion : To be honest I reviewed the links before checking my serp tracker, and I'm quite surprised it did move the needle. From the quality of the links, I would not buy a larger package tough. If you have a discount code, you might give it a try and see how it goes for some of your pages, and hopefully you will be as pleasantly surprised as I am.
