- Be the Dominator in your Niche
Are you sure you are getting what you paid for and what you have been promised? Have you ever verified your report that you have got assured metrics?
Why can't you be promised that the sites with your required metrics before placing the orders? You are supposed to be get what you've paid for.. So it's better you make sure that every link will be as you expected in prior.
3 Reasons why the little things matter in Link Building
-> Permanency : Backlinks are not just the thing that boosts your site in SERP. It's the source and visible reference of your site. I know, no one would like to lose the reference at all. So its needed to be permanent - And To be Gradually increased. Once again, Every link is not just a link but its the source to decide the life of your rankings. Be careful on choosing them.
-> Quality : Quality doesn't mean not only PR stuffs. It includes a lot metrics - Let me tell you some more important metrics most considered in rankings. Google's Page Rank, Moz's Trust, Rank, Majestic's Trust Flow, Citation Flow, Back link Profile of the Link source, Alexa Rank and so many there... Quality always matters more than Quantity.
-> Content : Imagine how worth a back link is to your site and isn't it needed to be from a super good & informative articles? Article should talk about the topic of your keyword not only about your site, it should talk about generally not like reviews, it should not be written one-sided, should be impressive to the readers and make them enjoy reading.
These are just the little and common things, We(most of us) are missing every time - If everything above is perfect, Can't it rank your site? Can't it keep ranking permanently? Obviously It Can.
So what the Service it actually is?
Authority (not just DA/PA) - Authority of a Link can be calculated by all its important metrics I mentioned above in the first reason. It can make you feel like every single link you build is worth triple than the money you spent!
To be explained simply, I have been collecting the sites of 50+ DA with Legit PR and other important metrics like Majestic, Moz and Etc.. Still I'm collecting the sites and trying to get account or get the contact who have access to the sites. So far, I have come up with the following sites (Though I have 100 more sites in Hand, I'm making sure that I can post on them - I will update that list soon in this thread)

Undoubtedly, you should have been inspired with the sites, metrics and mainly with the price.
Kick a habit of getting ripped off every time you buy links - Let us give it a try once to never be getting disappointed.
MORE THAN 10 EMPLOYEES HAVE BEEN WORKING THESE FOR MONTHS TO COLLECT ALL THEST AT ONE ROOF! EFFORTS FROM US WILL NEVER LET YOU DOWN!
P.S 1 : The sites are not free resources/publicly accessible. The real price of links from these sites are way costlier than you see here!
P.S 2 : I will be updating the list every week as much as the sites I will have been getting access to.
