The one-page wonder

If all of the content is squeezed into one page, like the example, the page won't rank well for anything (baring off page optimization).
Google keeps track of how many times users click 'back' from a search result to a search page. Needless to say it's going lower the subsequent rankings that the dentist page receives.
Decreasing the number of pages through clever AJAX use can improve user experience. But it still makes sense to have different chunks of content on different pages, linked together. The SEO implications are a reflection of this.
One of the commenters made a good point that he had to navigate too much to see the phone number. IMO, the phone number, address, and a link to a map should be on the screen at all times (using CSS fixed positioning).
Having accurate information in local directories would be considered "off-site" factors. Off-site factors are very very important, but does not negate the importance of proper on-page SEO.
And yes, for a website like the example, I think the contact info should always be very easy to find near the top of the page.
Here are queries I tried: 1. "parkside dental" 2. "parkside dental goldsworth"
I found it with the second query, it's the third result.
"There definitely can be some negative SEO effects..."
There definitely CAN BE negative effects, if you do not know what you are doing. You should be properly building the out the page's hierarchy as well as relevant inbound and onsite links (with id anchors at the end) to accompany that hierarchy.(Please note I am not suggesting links like "http://www.site.com/#about-us" can rank in google)A one pager, in my opinion, can be great for a small business.
You would definitely need to provide the user with conventions they are used to such as (contrary to DECH's blog post) providing pseudo-navigation at the top of each section.
Of course none of this matters if you aren't putting in any effort to convert that user into a possible customer. So a few things to include:
- scrolling contact info
- contact form
In the end the user get's "faster page loads", and therefore more gratification from using the website.
Disclaimer: This was just a stream of thought, I do not encourage or discourage one pagers for any given case.
2. The more content you squeeze onto one page, which could be spread across multiple pages, means the keyword density will be lower.
3. The page will not rank as well as it could have. It's basic SEO. Maybe dentistry isn't a very competitive niche and you can get away with a lower keyword density in the body text.
2. True, but see my first point.
3. True, BUT only in a competitive market. In my original comment I said "...can be great for a small business.", I probably should have used the words "local small business".
Because ranking for something like... "Miami Electricians" or "New York City Dog Sitters" would be easy and would be most effective (in my opinion) with a one page site.
From a business perspective, there are different reasons for having a website (I tried categorising at http://www.shirlawsonline.com/blogs/171-there-are-only-four-...) and I would suggest only a small subset of the simplest reason would fit into Dech's disclaimer - for the rest, this would be painfully wrong advice.
Even if we didn't have to contend with the habits and training that users have, I doubt this would be better. Is he arguing that a navbar with links to the appropriate sections is not worth the space it takes? If not, is he arguing that the benefits of everything being on one page (more useful browser find, I guess) outweighs the downsides (seo, users wading through mountains of text, scrolling required to access navbar, etc)?
On the other hand, check out songza.com for some smart one-page web antics.
A page per section makes it easier to focus on that section. I think it has to do with the unconscious processing of visual information.
Also, if the one page technique was superior I would expect it would have become the dominant method on the web. Evidence suggests otherwise.
I would have worked more or less the same as a 2- or 3-page site I think. With only one page you don't have the lag associated with page load every time you want to see a different section of the site.
...goes both ways.
