MozCast.com - What happened on the 27th? Hottest day of the month!
Anyone got any idea of what changed in the Algo on this day?
Cheers.

My short-term goal is to provide some at-a-glance drill-down metrics (like domain diversity or EMD influence) on the Mozcast site. That way, when something happens, people can immediately look at half a dozen metrics and see if there's a pattern across the data as a whole. No ETA on that yet, but hopefully within a few weeks.

Thanks as always for the help Dr. Pete, much appreciated! Seems like there's a lot going on with the algo at the moment, guess we're all just along for the ride. Thanks for mentioning the MozCast tool (http://mozcast.com), very interesting and a great graphic to help me know I'm not crazy haha, and a long needed tool overall; I look forward to seeing the added functionality you guys incorporate in the future.
People seem to be experiencing similar issues in my thread (http://www.seomoz.org/q/google-algorithm-update-july-30-2012-anyone-else-notice-a-major-drop-in-keyword-rankings), so I referred them here.
If you guys get a handle on what the flux is all about, please let me know or better yet blog it to the Moz faithful. Thanks again Dr. Pete.

Each day, we take the current top 10 and compare it to the previous day's top 10 (for any given keyword), and calculate a rate of change or "delta".

Unfortunately, we're not sure yet. We've had some strange data discrepancies in the past week. Long story short, there are two weather "stations" (A and B) - they usually run very closely in sync, but they've diverged the past few days, peaking on different days.
At first glance, it seems like Panda 3.9 rolled out over multiple days, like Panda 3.7 did, and may have masked some other updates. Oddly, the official roll-out day of Panda 3.9 was one of the lowest-flux days in that group. A similar pattern has happened three times in the past two months, and it's unclear why. Some updates, like Penguin 1.0, seem to be one-day, single-shot events. Others get released and adjusted over a few days.
We'll be trying to provide more analysis going forward on the MozCast Twitter feed (@mozcast) and possibly here on the blog for major events. Happy to field questions here as well, though.

I noticed a big drop on the 30th for our site, which I've asked in a question here: http://www.seomoz.org/q/google-algorithm-update-july-30-2012-anyone-else-notice-a-major-drop-in-keyword-rankings
My guess is that it's another Panda iteration combined with the Venice local update, allowing the same site, different pages to rank multiple times for the same keyword(s). But at this point I'm not sure.
A few of my pages have rebounded a few spots but have not gained any where near there original positions (most went from page 1 to page 3-4 of SERPs).
Glad to see it's not a completely isolated incident.

Duplicate content on .co.uk and .com TLDs with different domain authority
What's the best approach to take for a site that has identical content on the .co.uk and .com versions of the root domain? The .co.uk version has a significantly higher domain authority (54 vs 32 according to Open Site Explorer - see attached screenshot). But it's an international company with its largest customer base in North America and customers in over 60 countries. The company does not intend to localize content. My initial thought before seeing the domain authority was to 301 redirect the .co.uk to the .com domain to consolidate all the link equity under one international TLD. However, I wondered if the higher domain authority for .co.uk would be passed on if we did this. I figured that a non-UK audience would be more likely to trust a .com site. I still think 301 redirecting .co.uk to .com might be the best strategy in the long term. But is there likely to be a dip in rankings and organic search volume in the short term until .co.uk is replaced in the index by .com? I'd really appreciate your thoughts on this. CbVnfSO.png

Working with country specific domain names vs. staying with .com
I've recently inherited a client that has a country specific domain for Canada (.ca) but there is also a US branch for the company at the .com address. They have a direct competitor that operates also in the U.S. and Canada that has decided to operate entirely under the .com address and re-direct all .ca traffic to their .com address. When I compare the link analysis data for both the .ca, .com, and competitors site, I'm finding there is a huge difference between the .ca site and the competitors site, but not a huge difference between the .com site and the competitors site. For example, the domain authorities are as follows: myclient.ca (Canadian branch) - 22 myclient.com (US branch) - 46 competitor.com - 53 When I do a brand search for my client in Canada, the Canadian branch website shows up first, but the American one is second. At this point, would it be better for my client to consolidate the two branches into the .com address and focus on increasing external followed links to the .com website? Or, is there merit in continuing to create a separate inbound link strategy for the .ca site? Thanks.

What is the best way to rank well on both Google.co.uk & Google.com?
I am working on a website that is primarily a UK based software company but is now expanding into the US. The website is a .com site and is not geo-targeted to any specific location. Currently the site ranks well on Google.co.uk for a number of the focus keywords. We are now targeting Google.com as well to increase visibility in the USA. The site is ranking number 1 for one of the focus terms on Google.co.uk but no where to be seen on Google.com but on another term the site ranks 3rd in both Google.co.uk and .com. There are a number of other terms that rank on the first page in Google.co.uk and on the 3rd or 4th page in Google.com. The server is located in Germany and I do not want to geotarget the site to the US as I am concerned this would have a negative impact on the .co.uk ranking. The site currently has a mix of .com and .co.uk links pointing back to the site, in actual fact possibly more links actually come from US sites already. My original plan was to just focus on building links back to the target pages from US sites rather than creating a US folder on the site and geotargeting that section of the site in WMT and having to build page authority for a completely new page with no existing backlinks. But now that I have a number 1 ranking on .co.uk and the same term not ranking at all in .com as well as a postion 3 ranking for a term in both .co.uk and .com I am slightly confused as to the best options. Any help, advice, opinions would be greatly appreciated.

Freelancer.com: Same Content on Different TLD?
Take a look at freelancer.com and freelancer.in. Both have the same content. I check for rel=canonical and freelancer.in has one to itself. Not to the .com version. Both the sites are indexed in Google as well. Do you think high authority sites like freelancer can get away with duplicate content?

I have on site translated into several languages on different TLDs, .com, .de, .co.uk, .no, etc. Is this duplicate content?
Three of the sites are English (.co.uk, .com, .us) as well as foreign (.de, .no, etc.) - are these all seen as having duplicate content on every site? They're hosted under the same EpiServer backend system if this helps. But I am still copying and pasting content over each site, and translating where necessary, so I'm concerned this is indexed as being large amounts of duplicate content. Site traffic doesn't appear to be suffering but as I'm currently putting together new SEOs strategies, I want to cover this possibility. Any advice on ensuring the sites aren't penalised appreciated!

International SEO with .com & ccTLD in the same language
I've watched http://www.seomoz.org/blog/intern... and read some other posts here. Most seem to focus on whether to use ccTLD, subdomains or subfolders. I'm already committed to expanding my US-based ecommerce to Canada with a .ca ccTLD. My question is around duplicate content as I take my .com USA ecommerce business to canada with a second site on a .ca URL. With the .com site's preference set to USA, and the .ca site's geo preference (automatically) set to Canada, is it a concern at all? About 80% of the content would be the same. FYI, .com ranks OK in Canada now and I want .ca to outrank it in Canada. I know 'localizing' content within the same language is important (independent of duplicate content), but this might not be viable in the short run given CMS limitations. Any direct experience to help quantify the impact here between US and Canadian ecommerce? Adding: I'm not totally confident here. From this google webmaster central post it seems that canonical tags aren't needed. I tend to think nothing is truly neutral and want to be confident regarding whether to use canonicals or not. Is it helpful, harmful or harmless? My site already has internal canonical tags and having internal and external would be a pain I think. @Eugene Byun used it successfully, but would the results have been the same without? Thanks!
