As I said, it is too soon to analyze ... so it would be better to stop to speculate about the "new relevancy" of IBL, OBLs, keyword density, age of site, younameitwehavehadit ...Just to keep people up-to-date, Jagger3 is not visible yet. Last week I said that Jagger3 would hopefully be visible this week. Itís possible that it might be visible by Friday or this weekend. Iíll let you know when Iíve got more info.
It IS tempting to speculate, but in this early stage will do more harm.
