Hi, so I'm looking in the marketplace and I'm so overwhelmed by all of the services (that looks great and professional) offering PBN link building service... My website is very important for me, and I have money to invest - I just don't know how I can make sure what I'm getting is worth it. I just don't know what I can trust. Is the simple answer is "you just can't know" ? There is a way to make sure the service I'm getting is actually worth it? What results did you guys had with these services? Did you website really ranked higher for long time? Important to say I have an established website 3 years old and I have around 40k organic visitors from google every month... But it's going down every month....So I just need to boost up my SEO.... HOW? I just afraid from to be penalized... Any offers?
