Hi Joanna,
Great list, thanks for putting it together! Another couple of tools we use (That you might consider for your list) are majesticseo.com for backlink profiles, and our own SEO Audit tool. It compares website optimisation and metric to your competitors and gives an overall score. Here’s the url:

Oh, and I noticed the link to the “Prospect Domain Checker” returns a 404 error.
Thanks
