So this has happened for the second time for my first site which was an aged domain, the site rankings are still stuck on 15-16 and it won't move anywhere regardless of any link building. this site is page 1 when i search from any country IP other then the USA. The second site is new one and is stuck at position #38 for last 6 days, before that it was bouncing around #11-29, this site is also page 1 when i search from any country IP other then the USA. Are there any google filters which can lead to such thing? i use over 100 anchors with 5 being the main ones and built around 300-400 backlinks to the second site i mentioned above. looking forward to answers.
