Alright so I just spent two months and about two grand testing a link building agency that cold emailed me with some crazy case studies, figured I'd run my own experiment to see if it's worth it or just a total scam, the pitch was 10 guaranteed DR 70+ links for a money site in a finance niche, they sent over their portfolio and everything looked clean. So here's the raw numbers, they delivered 12 links actually, average DR 72, but the traffic on those sites was basically zero, like sub 100 monthly visits according to Ahrefs, after 60 days I'm seeing a grand total of 14 referral visits and my target keyword moved from position 42 to 39, that's a three spot bump for two thousand dollars, anyone giving advice on this stuff without posting a screenshot of their own GSC or rank tracker data is just guessing and wasting everyone's time, correlation isn't causation but I'm pretty sure the links did nothing. My take is if the sites they're placing you on have no real traffic or audience, the DR is just a hollow metric, you're paying for a number in a database not actual authority, I'd rather spend that budget on one legit guest post on a site that people actually read, feels like most of these agencies are just resellers for crappy PBN networks with fancy reports
