Modx revolution- getting around index.php vs. root duplicate content issue?

[G2W]

Basically, SEOMoz bots are flagging our index.php and root files as duplicate content of one another, therefore cutting the page authority of each.

What we want to do is make the root the canonical preference over index.php.

Ordinarily, we should be able to do this in the htaccess file. For some reason, as the site has been built into a cms using ModX Revolution, this does not seem to work.

We've tried A TON of htaccess rewrite mods to resolve this issue to no avail. We have also tried revising our sitemap to include only the root address.

Any ideas? We'll try most anything at this point.

Thanks in advance.

You can try a canonical tag in the header:

Takeshi,

I forgot to include that we had already tried placing a canonical link in the home template header. Unfortunately, it did not take care of the issue for us.

Thanks for the idea, though.

Any others?

The canonical tag should take care of the duplicate content issue. When you do a site: search of your site on Google are multiple versions of the same content showing up? If not, then the canonicals are doing their job. It could just be the case that SEOMoz's crawler just hasn't re-crawled your site yet (it can take a few weeks).

Takeshi,

Sorry it took me a bit to get back to this post.

I would appear that this issue has been taken care of, presumably either through the canonical tag OR a sitemap resubmission that I had cleaned up.

However- When I do a search for domain.com/index.php in Google, it does still appear- is this something to worry about in your opinion?
