A free website audit: fifteen checks, and what 1,089 sites got wrong.

The most basic check, and the one that fails most brutally. Fifty six of the sites I checked did not respond at all. A site that is down when a buyer arrives has no other problems worth discussing.

Measured on a mid range Android over 4G, not on a fast laptop. Under two seconds is the standard I hold my own builds to. Just over half the sites I audited responded slowly.

Checked across the sizes people actually use, from a small phone to a wide desktop. Anything cut off, overflowing, or scrolling sideways. Broken layouts on a phone lose the visitor before a word is read.

Buttons and links big enough to hit, text big enough to read without pinching, and enough contrast to be legible outdoors. Small targets cost you enquiries quietly.

Whether every page that matters has a title and a meta description, and whether they say something a person would click. A quarter of the sites I audited had no description at all.

One clear H1 per page, and a heading order that describes the page rather than decorating it. It is a small thing that keeps turning out to correlate with everything else.

Whether it is there, whether it is valid, and whether it describes what the business actually is. Twenty seven per cent of the sites I audited had none at all, which is a free advantage left on the table.

HTTPS is not the end of it. Insecure resources loading on a secure page still break the padlock and still get flagged, and it is usually a leftover nobody noticed.

Robots rules, canonicals, and the noindex tag somebody left on after launch. I have found live commercial pages hidden from Google by a single line nobody remembered writing.

Not your own company name, which you will rank for regardless. The searches that mean money, and whether you are anywhere near them today.

An honest read of what you are up against. Some searches are worth pursuing and some are not worth your budget, and saying which is more useful than a list of keywords.

How the site links to itself, and whether the pages that earn are one click from the front or buried four deep behind a menu nobody opens.

After a redesign or a move, old URLs often die quietly and take their rankings with them. This is the check that most often finds something already lost.

Watched on the network rather than taken from a plugin's description of itself. This is the part regulators act on, and the part most banners get wrong by default. I also check whether your analytics is recording anything at all, because plenty are not.

Privacy, cookies, and an Impressum where you trade. Present is not the same as correct: they have to match what the site actually does and actually loads.
