Filter or penalty? Ranking down - what are the possibilities?

[lakr]

Dear all,

My top keyword has been ranked well at top 5 for almost a year for Google.com, top 1 for Google.com.au, and .Ca. However, recently, its ranking downed dramatically to top 15, and top 10 for .Au and .Ca NO matter I got many good links pointed to it.

I guess that there are some filters happened here, so that I can not increase my ranking. Most of the links are one-way, and no reciprocal, no paid links, and some of them are from my own other websites.

Could you please tell me what will be the possibility for the down in ranking? if so, how can I pass the filter?

Thank you.

If it's local sites that have overtaken you you'll need more local links, if it's other "foreign" pages there may be a problem with your linkage.

The days when a page could rank world-wide are just about over....

Thank you for you reply. It is easy to understand how to rank well on .com.au and .ca (links from sites hosted in AU or its extension is .com.au).

And my question is how to rank well on Google.com in USA?

Check to see if you are down on other data centers than google.com. I have a strange filter or penalty going on my top keyword that seems to be occurring at the last step as is still good on all data centers but it's down on google.com

Not that this helps you any as I've been working several months on solving the problem with no luck at all.

US G.com results look very US centric, I suspect "local search" plays the part that "Pages from..." do in national Gs.
