Here is a recent article from July 5th:

It will all depend on how your site is setup and what type of server.  Can you give us more detail on that?

Are you sure that those spammy links are what is helping them rank?

I wouldn't drop to their level, but focus on white hat marketing.  And if you want links, create a new campaign targeted on building solid relationships for the good links.

It may not be right now, but Google is slowly rewarding better content sites.

I track the "Full List of Link Metrics" on me and my top 10 competitors monthly.  And I also keep track of the "Anchor Text Distribution" and track link to root ration.  (Search SEOmoz for some good info on that)

Great information.

I didn't know if you export OSE's data for tracking purposes.  Every time SEOmoz has an update, I download all the info into an Excel spreadsheet to track monthly.

Besides PR (not really for SEO purposes) how do you track the site.  Are you utilizing http://www.opensiteexplorer.org ?  How are your numbers there going.  Google's PR isn't really a good number to use since it is only updated about every 6 months.  Focus on SEOmoz's tools for more accurate reporting.

Great!  Then focus on the .br and redirect the .com

If they have a ton of links (going out?), most likely it isn't worth it.  The DA is low.  What is the PA?

if you are going to do it, I would start out with an existing post link (as long as there aren't a ton of other links) to see if you get any juice.  And on that page see what the PA  and MozTrust is.  And just track that for a few months.

Links per page - http://www.seomoz.org/q/max-of-recommended-links-per-page

And also remember that you will want your more important links towards the top.  And I would keep your links to a minimum per page.  It all depends on what you are doing.

I would also speed up your crawl rate with Google in GWT.  Yes, you can remove certain pages, but Google will need to re-index all the other pages that use to link to them.

It would all depend on if you want to focus your SEO in Brazil, http://www.google.com.br/.  If that is the goal, then use the .com.br.

I guess we would need to know a little more about what your plans are.  You may be able to utilize both even with similar content.

We have also seen the same minimal numbers.  But it was very interesting to dive in and start to investigate.  I have been reviewing all sections in both Analytics and GWT.

It will be interesting to see which pages are receiving the most clicks vs. impressions.

Honestly, we just need more time and data.  Not too much activity as of now.

Interesting.  Would you recommend that most people add that meta?

Googleon and Googleoff tags are commands for the Google Search Appliance

I would say that it all depends on how they are currently ranking.  If you are just in the beginning stages of SEO, then I would say go ahead and make this step.  But if the site is already doing well then I might hold off.

There was a great answer about here: http://www.seomoz.org/q/website-restructure-good-or-bad-for-seo

Restructuring allows you to organize your content into "Silos" and eliminate some of the unnecessary links through JSON objects, iframes, and nofollows (some debate there on which is optimal).

The Downfalls: There will probably be a 30-90 day dip in traffic but if you do page-to-page 301's it won't hurt nearly as much. Anytime you change URL's you are likely to see some inbound links drop off, but that happens when the pages don't change, so it's going to be minimal. Sure, 301's might drop some of your PR during transfer, but only a minimal amount according to matt cutts.

The Benefits:  Organizing your content into silos and pruning cross-category links will allow you to control the flow of pagerank and anchor text much more effectively. Bruce Clay has a huge amount of resources on this, and they even cover it on their blog.

Will it be painful? Yes.

Will it be worth it? Yes.

Google's PR doesn't mean anything to SEO.  Use Open Site Explorer to really evaluate the site.  (They could have just purchased that domain with a high PR). I would also spend a bit of time and evaluate the other links you would be grouped with.  Again, if they are quality sites in your industry, then that may be alright.  But if they are just a bunch of spammy sites, then keep away.

Just tried it.  All good.
