With HTML 5 coming down the track, it’s worth being aware of how it will affect search engine optimisation.

It introduces some new tags to HTML:

<header> <article> <asside> <nav> will all help the search engines better understand the layout of a page.

New Link Tags:

alternate – Links to an alternate presentation of the current web page
author – Links to a web page related to the author of the web page
external – Links pointing to external domains
help – Links pointing to relevant help pages
license – Links to licensing terms of the current document
next – In a series of web pages, this links to the next web page
nofollow – Indicates that the link is not endorsed by the site
prev – In a series of web pages, this links to the previous web page

All this seems to make it even more important that your website is built professionally by people who know how SEO works too. HTML started off very simple, and seems to get more complicated to do well every 2-3 years.
