Covers the basic components of a content audit, covering both attributes of the content and its performance. Gives a good foundation for a DIY content audit.

One area of disagreement: Bounce Rate by itself is not a good metric of performance. Visitors find your content and it meets their need. They leave, creating more bounces. Good? Bad?

And what bounce rate? Hard? Soft? Hard bounce rate is probably a better KPI as it takes into account engagement on your site. (If visitor hits a page and leaves, regardless if they do anything on the page, like select a link, that’s a soft bounce. Hard bounces only get counted when a visitor hits a page and leaves without interacting with the page in any way.)

You don't know unless you also consider Time on Page or Return Visits. They bounced after spending time on the page and found it valuable enough to return to your site later? Good.
