Compare two domains
Pick two domains. We run the quick grade on both, line up the 8 checks side by side and show which one scores higher. The whole comparison lives on one link you can share.
What a comparison tells you
Who leads, and by how much.
Both homepages get the same 8 checks, scored the same way, so the gap in points is a fair one.
Where each one falls short.
The checks sit side by side, each marked as a pass, a partial or a fail.
What a grade can't tell you.
Whether an answer engine cites either site. A grade is readiness, not citations. To see a real answer and its sources, run a page audit.
Only need one domain?
The quick grade runs the same 8 checks on a single homepage and gives you the letter, with its own link.
