No link building required here . This is PANDA (bad low quality content, duplicates or even bounce )
Do a site audit and find the issues my website is currently facing. The website is a bit new but ranked high recently. With Google panda 4 the traffic has dropped to half for some reason.
I have cleaned many duplicate links researched from semrush, ahrefs etc. It would be better if someone could clearly point out the issues for a better fix.
Also when bidding let me know if you have fixed any panda issues in the past or recently.
