The ranking whichever way we chose to do it must be robust and stable to small random changes;

Impact of Bridges for A/H: If there is random link connecting the disconnected components; now even the lower cluster`s authority and hubs will be taken into consideration hence there can be a considerable amount of change in the ranking pattern and it can no longer can be considered a stable ranking.
This can be fixed by:
1)Having weak links between all the pages.
2)Consider the cross product of Primary and Secondary eigen values(which is always perpendicular to the plane containing Primary and Secondary Eigen vector)
