My "inlinks" amount always change.

anyone install yahoo tool?

 

This is something that happens with all sites I think it's directly related to the
data centers.

 

Yes in links and rankings can vary depending on which data center you happen to hit. This can vary geographically or perhaps even randomly.

 

Thanks for your opinions.
i take off yahoo check inlinks tools
beacuse if you refresh page, it would cause IE break down.

 

Almost every time it display the same result for my site links.
