What are the rules of engagement with respect to SEO in HTML 5?
Examples of things we have been mulling over with no conclusion:
Are you penalised for not using <head> and <body> tags?
Do links in <nav> blocks get prioritised for follows?
With <aside> (no bside though), <section>, <summary> and <details> which ones carry the most weight for content, one-liner descriptions and keyword tags are there search engine implications?
If you use CSS to put a <footer> element at the top and a <header> element at the bottom (not that you would but it may be construed as such by an incomplete spider implementation)?
Does the use of placeholder attributes on <input> show you are more user focused?
At the minute we are haphazardly pinning the content on the donkey with regard to tag usage but would be interesting to know if anyone has any insight into the "correct" tags to use with regards to SEO.
