Hi all I have a website which is ranking in google first page ( 6th position for main keyword) and other secondary keywords in second page. My question is , is it the right time to use PBN ? Should I target both inner pages and main page If I use PBN ? The competition is very low in first page and second page and my domain is 3 year old. I have around 45 backlinks from different source without using PBN.
