How does Google see a Single Page Website?
Google has come out and said that if the structure of your website is correct and the content it contains is great you should rank as you would normally like any other website. Here is a video of Matt Cutts, Head of Webspam at Google on the subject:
So, according to Google, I should be fine? Wrong!
Google is saying that your website will be indexed the same as other websites, meaning it will look at the content and pick out the structure to show in search results. See, every page that gets created on a regular website is an opportunity for you to add meta data and structured content to rank for multiple topics. The use of a single page website does not, because only one page will be indexed.
When should a Single Page Website be used?
While it may not be beneficial to use a single page website from an SEO perspective, a Single Page Website is great for single topic focused websites and PPC/Adwords Ad landing page.
That’s great and all but…
If you do have a Single Page website, don’t panic. There still is a way for you to rank on search engines however the approach is more based on linkbuilding than on-page optimization. Which means you will need more high quality referrers than your competitors.
Single Pages are cool, but they are not as effective
To sum it up, Single Page Websites are harder to optimize for search engine rankings and targeting multiple keywords which is something many businesses, small or big depend on, as an initial and sometimes, only source of traffic.
