In this case I just try to infer and understand from various sources that I read, because I myself was not even arguably SEO practitioners blind to SEO.
It's New in HTML5
At the beginning to create a web layout we use the <div id = "header"> for the header,
<div id = "main-content '> to the article, <div id =' sidebar '> to the sidebar, and <div id =' footer "> for the footer. The picture is like this:
By using HTML5, the structure becomes <header>, <article>, <aside> and <footer>. To change the display, add and modify CSS id, <header id = "header">.
The advantage of the above structure using HTML5 semantic search engine makes it easy to discover which parts of a blog / website. With a structure that is easily understood by the search engines, of course, will have an influence on SEO itself.
Does HTML5 will become the First Rank in Google?
Do Not. HTML5 Semantics only facilitate the search engine crawl blog content as a function of Use Microdata. Blog / website using HTML5 does not guarantee to be ranked first on the search engines for poor content and poor quality of backlinks.
The most important thing in SEO is the quality and relevance of the content, as well as a quality backlink. Blog / website that does not use HTML5 semantics if it has both content and quality backlinks, it will be a champion in the search results.
As a result, if a blog using HTML5 semantics, quality content and have good backlinks, then no doubt will be more powerful in SEO and certainly occupy top positions in the search results (SERP).
Conclusion
HTML5 semantics needed to support SEO, but with the condition do not ignore the content and backlinks. What does it mean HTML5 structure for a blog that poor poor content and backlinks.
That's the conclusion I personally, may be different from the opinion of my friend all. Please fill his heart written in the comments field.
