What is actually
wrong with your site?
Paste an address. You will get a straight answer in about ten seconds, with no sign-up and nothing emailed to you.
Checks one page. Nothing is stored and no address is kept.
It only reports what it measured
Most free audits pad the list. They score your speed from one sample, guess at broken links, and hand you a number out of a hundred that means nothing. This one reports the things that are true on a second run and that you can check yourself in a minute, and then it tells you what it did not look at.
That is the same rule the paid work follows. Every site I build ships with the audit output attached, so nothing is claimed that was not measured.
