This level of diligence is normally a bit undue for a simple website. Here, the intent is to showcase the validation tools (and a reference implementation for the feasibility of high scores).
Each general link should take you to the main page for that test, so that you can test an arbitrary domain. Each "(TS)" link should take you to results for techsolvency.com (when feasible).
You can verify the results below yourself. You can also generate links to test your own hostname against all of these tools!
