Hi Recently i got stuck in a wired case.. My site has different country pages like usa, uk, germany, australia Now each country is doing good in google except UK and USA On further research I am quite assured that These pages got some kind of penalty. When i search some unique lines from that page, instead of my website page other websites pages are ranking also the link on the uk page are not indexed. All the content on these pages are unique except the shopping cart each page has the same products and these products pages has dynamic url structure with view id parameter. In google webmaster central, Google shows that it is neglecting this parameter. Also I think the reason for penalty is aggressive do follow blog comment spamming Any suggestions remove this penalty?
