What a Website Audit Tool Can't Tell You (From Someone Who Built One)

We built a free website audit tool at CoderCorn, so I get to see how people react to a score. A lot of them treat it like a grade on a report card. It isn't one, and I'd rather say so than let you walk away with the wrong idea.

What a tool is good at

Audit tools are great at checks that are mechanical and repeatable: a missing title tag, a bad canonical, oversized images, render-blocking scripts, broken structured data, missing alt text. A tool can find those in seconds, and it will find them the same way every time. That makes it useful for before-and-after comparisons.

What it can't see

It can't tell whether your message makes sense. A page can score well and still leave a visitor wondering what you actually sell.

It can't fully judge accessibility. Automated checks catch some problems, but whether a keyboard user can complete your form, whether focus order makes sense, whether a screen reader announces things in a useful way: a person has to test that.

It has no idea what matters to your business. A page that scores badly may be a page nobody needs. A page that scores perfectly may be the one losing you customers.

It also can't tell whether a page answers the question the searcher typed, and most tools only see what an anonymous visitor sees, not what happens behind a login or after an interaction.

How I'd use a score

Treat it as a to-do list, not a verdict. Fix what's wrong on the pages that matter first. Re-run after changes to confirm the fix worked. And if the report raises a bigger question, like "do we need to rebuild this?", get a human to look.

That's why our free PageScore tool is a first look, and why we offer a separate human-reviewed website diagnostic when the question is bigger than a checklist.

A good tool tells you what it can't see. If the one you're using doesn't, be a little careful with its results.
