Before we get to the infographic, I recommend checking out the SearchEngineJournal blog post which originally shared this infographic in contains much more information than the graphic displays, you can check out the post here.
When it comes to auditing SEO this infographic helps remind us of how complex the SEO channel can be, but at the same time it can be actioned as a list of things to do.
When proactively trying to grow your reach through SEO I think it is much easier to simplify the channel. I am surprised tools such as Google Webmaster tools, Xenu / Screaming frog didn't appear more as ways to easily complete / check significant parts of the audit but other than that, this is a well written guide you should definitely checkout.

This is quite a comprehensive guide for completing an audit, though the key area missing I'd say, is to be clear on both the objective & reason for completing the audit. If you are not clear on this then you could waste a lot of time. By having a clear objective & reason you can:
- Save time & energy
- Focus on particular areas of the audit
- Prioritise actions based on the results of the audit
- Monitor results based on a couple of actions rather than changing everything and not knowing which actions worked or not
