We built an internal tool to do it for us, but basically you can do this manually.

Go to google, type in "site:YOURURLHERE" without the quotes. You can check a certain page, a site, a subdomain, etc... of course if you have thousands of URLs this method is not ideal, but it can be done.

It's a pretty well known fact that non-US versions of Google are not using the same algorithm and therefore are "behind". This could be the case where you are employing methods that a couple years ago were effective and are working well for .CA but on .COM not as well.

The biggest thing you can do is work on high quality content and build links. Remember, linking is somewhere around 70% of the algorithm alone. Work on getting more .COM authoritative links from sites like NYT, USAToday, etc...

Also, if a good portion of your links are from .CA, that very well could affect it too!

Personally, I like to fit in the site name or business name whenever I can. What I recommend doing is disabling any kind of auto-tagging for the site name and enter it in manually only when it fits and if it's relevant.

For example, All in One SEO Plugin for Wordpress by default appends your site title to the end of all title tags, no matter what. I disable this and do it manually so I know I have 100% control over my title tags.

It helps for branding purposes!

You load links into it, it then creates an RSS feed on their end that gets pinged. You can load any kind of link into it and it'll ping them.

Generally after I change a site structure or do a redesign, some URL's are broken and not working. In those situations, you need to do the following:

-301 the broken URLs to new URLs
-Take an accurate snapshot of where your link building efforts are pointing
-Make sure you don't mess up a page that has tons of highly authoritative links

After you do that and change your structure, it's a great idea to build links to your NEW structure to build back any lost authority and start ramping up those ranking efforts.

Does that make sense?
