Analysis of pages perceived value to users

[inhouseseo]

According to SEOmoz, the main ranking factor to become more important is Google's "analysis of [a] pages perceived value to users"

What does this mean? Is this Google's analysis of the on-page content (i.e reading level, readability, etc.)?

If I was going to evaluate the perceived value of a page to visitors I would look at....

-- how long do people stay on it

-- how far do they scroll

-- is the content substantive and include richness such as graphic or video

-- CTR in the SERPs

-- is it tweeted

-- is it liked

-- is it linked

-- is it bookmarked

-- are bookmarks used

-- how did it perform on reddit and similar sites

Any one of these can be maniupulated and any one of these can send false positive.  However, using some of them as a constellation would probably work well.

Perceived value to a user is probably a more advance subject than I'm qualified to talk about but I would imagine that measuring it would involve; user engagement metrics, authority of the author, authority of the site hosting the content.

That was what I initially thought, but SEOmoz has usage data and social signals as separate factors.
