What You Need to Know about SEO

If anyone wants to learn most things about SEO, I highly recommend "Getting to Know SEO" by Andre Kibbe, it's the best book I've read so far on the matter: http://rockablepress.com/books/getting-to-know-seo
You could argue it would make sense to keep their blog as a folder like they do for /jobs and /about for coherency. I would agree.
(Also, whilst he's being modest here, Patio11 is something of an authority on SEO himself.)
Edit - yep, here: http://www.seomoz.org/learn-seo/domain

I can't tell you that all the advantage was from the url restructuring, but it had a marked impact. Having tried similar things on test sites, I do think it makes a difference.
And that is what SEO is about… testing assumptions because there is no definitive answer. Even Matt Cutts isn't going to tell you everything 100%.
Also, that article is five years old.
As to whether blog.example.com and www.example.com share trust metrics, sentiment among SEOs are mixed. Consensus estimate among SEOs who I'd trust with my business would be close to "blog.example.com and www.example.com are treated as at half-arms lengths for the purposes of accumulating link juice and virtually identically for the purpose of awarding link juice." This suggests that you want as few subdomains as reasonably possible for publicly visible content which will either attract links or which you want to rank. For similar reasons, I'd suggest most startups would require a darn good reason to have more than one toplevel domain.
Google has said not to worry about this issue, but that a very common answer from Google when probed about any specifics of their algorithms. Google will also say things like "Quality content is 99% of SEO" which if it is true is true in the sense that Santa Claus is true -- perhaps a good message to tell children but I would not base my ability to feed my employees' family on the likelihood of finding a jolly fat guy if I went to the North Pole to check.
And if you're a local plumber who, other than a lack of incoming links, provides great service? Social mentions of that great service (nofollowed on Twitter, for example) aren't going to help the ranking.
With startups and side projects, isn't the end result of this sort of thing that people have to create blogs/guides/content that is outside their core focus?
"With startups and side projects, isn't the end result of this sort of thing that people have to create blogs/guides/content that is outside their core focus?"
You're right. But it has to somehow relate to what your start up is doing, otherwise it won't get you a lot of traffic, nor will it do a lot to push you higher in the search rankings.
Edit: spelling The -> They
If you're genuinely good at a much-needed trade, ROI-positive conversion funnels for tightly-optimised keywords are much easier to set up than for most Web entrepreneurs.
I find the hardest thing about outsourcing SEO is that it really does start with the content, and you shouldn't outsource that. It is important to identify your keywords and focus on using them properly when writing this content. Good content, with a fine balance of writing for bots and humans, is very important. Good SEO copy is not the same as how we were taught to write an essay in college (or High School.) It should not be as verbose and takes a little getting used to writing in that style. Use keywords like you would salt, enough but not too much, and in everything.
I know google tells you differently but in most cases you have to be active and pimp your content. Like what Priconomics is doing here.
That's not a bad thing, these guys are doing it right. Listen to their advice.
Use descriptive URL's, title tags, meta tags and headlines - and consistently get high quality relevant inbound links - and you'll be in good shape.
If you're a Jim's Plumbing site, you should be okay following your advice. If you're a giant site with many pages to index, you need to focus on structure. The flow of pages is important, and it's more than setting up breadcrumbs and pretty URLs. This kind of problem needs to be looked at when building a site, you can't just drop some code in after you've launched.
