One of our clients had a sudden drop on a high trafic keyword in France since 8 october
After a deep analyse, we are sur that is not due to the site structure or content (no spam).
On Google webmaster tools, several important backlinks that where going to the root now go to an inside page and are so on 404.
eq : www..com is linking to my client site www.example.net but google has changed the backlink to
www.example.net/index.html since 8 october so they are now in 404.
this could explain the sudden drop in Google as the root has no real backlinks...
Anyone already experience such a "bug" ?
