This question is in regards to the article section and aside tags as it relates to best SEO practices. I've seen some tutorials teach that you should place an article tag and inside the article tag various section tags. However some books I've read have it the other way around and place sections and nested in them are article tags. Which of the two methods is the best, for the best SEO results and why? Obviously our job is to not only give the consumer the best looking site, but also a site that is SEO friendly.
<article>
<section>
<aside>...</aside>
</section>
<section>...</section>
<section>...</section>
</article>
<section>
<article>...</article>
<article>...</article>
<article>
<aside>...</aside>
</article>
</section>
This has nothing to do with SEO, the two structures have a different meaning:
A list of blog posts could be a section with an article for each blog post.
A long blog post could be an article with a section for each section/chapter.
