I was lucky enough to get the review copy from Politico and all i can say im impressed with the links i got back from him. Report is clean and professional and everything was done as instructed by me.
As advertised, I was offered powerful contextual links with clean high-TF domains( a total of 10 ). I could tell that the links were coming from good websites. The websites had good links and clean history.
The average TF score was 21
The average DA score was 17
The average RD score was 36
The content used is high quality as advertised. Although the domains were not really relevant to my niche the articles were niche relevant and all sites had different theme and design to them.
In my opinion, the backlink juice that you get from this service is good. It will strengthen your websites.
That said, it's too early for me to comment on the rankings. The report was delivered a few days back. It was delivered on TAT.
