It's also pretty awful alt text. Rule of thumb: Alt text should be
what you say if you read the page out over the phone.

Alt is about meaning, not descriptions.

Browsers are capable of indicating what elements are links all by

Site logos are almost always links back to the homepage, (and browsers
are usually capable of indicating the URL a link goes to if the user
asks) so this is redundant.

So typically a site logo would be something like:

<h1><a href="/"><img src="logo.png" alt="My Company"></a></h1>
