Heh - beers away! Happy to help

Hi, Tom here - I helped put together the ranking factors this year and you'll find that link velocity is included in the domain level link metrics section:

It actually rated pretty highly!

Depends on your use case but this is a good resource:

Personally I really like VWO: http://visualwebsiteoptimizer.com/ I like the way you don't need heavy code changes to run tests.

Hmm, I definitely think there is a page level element but Google have gone on record to say there's also a domain level impact.

I imagine that the definition Google holds of a "site" is used in this case rather than slapping the whole domain.

Does anyone have any case studies or examples of sites where a specific sub-domain was hit by Panda while other sub-domains were fine?

What's the general consensus on whether this was applied at the sub-domain or root-domain level?

My thinking is that Google already knows broadly whether a "site" is a root-domain (e.g. SEOmoz) or a sub-domain (e.g. tumblr) and that they use this logic when rolling out Panda.

I'd love to hear your thoughts and opinions though?

Yeah, all of these data providers are a little suspect. Especially compete!

Hmm - not sure I'm trusting those graphs. SEOmoz didn't see any change one way or the other with Panda...

I'd seen that site before, but 250,000 FB likes is just insane! Wow...

Great links Ed! Thanks for sharing. Got any more from the wider online marketing space? I think I see all the good SEO stuff but I'd love to know what's been big that's more similar to the "Poke the box" workbook (which I'm checking out right now...)

Thanks!

As you may be aware - SEOmoz are hiring for a marketing oracle (one of 8 jobs going at the moment: http://www.seomoz.org/blog/8-open-positions-at-seomoz). Their key responsibility will be to produce world class content about online marketing, seo and social media.

So, let ask you - what are the best examples of content in this space from the past 12 months? The very best of the best. Don't just think SEO, but any kind of online marketing content. Whether it's editorial, infographic, research etc etc.
