You need to provide me real blogs with decent Trust flow/ref domain metrics with traffic.
Good looking PBNs are NOT guest [login to view URL] blog must have some traffic (can be verified in SEMrush).
You need to provide me samples of your published blogs and pricing for each. It is a long-term work for multiple websites.
Mention "I know the difference between guest posts and PBN posts" in your response to stand out from spam automated bids.
