Does the page authority data also considers the on page factors like the presence of keyword in the title,meta text, and keyword frequency ??

The moz difficulty score considers four factors for the top websites. are the on page factors included in the page authority data ?

I do not think it includes onpage optimization at least from what i have seen

I don't see how it possibly could, it is just a number.  If it was taking into account a given keyword then it would an array of values for a given keyword - but it ain't!

Hi Viswanatha,

Short answer, no. Page Authority is based mostly on link metrics. That said, it takes many factors into consideration, including Domain Authority and trust metrics.

Page Authority is a comparative metric, meaning that all other factors being equal, the page with the higher PA would have a better chance of ranking for it's particular keyword.

So 2 pages, each optimized equally for the same keyword, with exactly the same title tag, etc (forget for a moment that this is duplicate content) the page with the higher PA would likely rank higher than the lower one.

You can read more about PA here.
