Duplicate content, &filter=0 and allegra?

Duplicate content penalty and allegra?

[foxtunes]

I'm wondering whether this has anything to do with an Allegra update ranking loss on one of my sites.

For one site unaffected by the allegra update, when I type in [sitename...] into google, it shows up as the same backlinks as the [sitename...] version. So both urls are consolidated and viewed as the same site. Both have the same page rank, backlinks etc

This must have been done automatically by the hosting company as i havent a clue when it comes to tinkering with my apache settings.

Now when I look at the site slammed in the latest update, hosted somewhere else, I see that the http:// www version has a page rank of 6, whereas the http:// version has a page rank of 1.

So in the search engine's eyes they view these as two seperate web sites?

If I type in &filter=0 for the keywords I'm back at 1

I'm thinking this could be triggering a duplicate content penalty...I was advised a while ago to perform a 301 redirect on all my sites so the www would always show.....Disaster is waiting around the corner when you procrastinate.

Anyone else seeing this?

This is normal, and I don't think that they would trigger each other as dupe content, and even if they did, you'd notice that only 1 was gone, not both.

I suggest the 301 though.

Thanks chico.
