Alt text and itemprop description

[abisti2]

I want to optimise the logo on our site. Our developers have presently got the site logo code like this:

601 character description, no keywords

1. How best to use the alt text and description?

2. Do I concentrate on alt text?

Isn't the 601 character description:
a) too long, and
b) an opportunity to add relevant keywords again, like the alt text?

Thanks Tom, yes that's very helpful

I would use schema on the URL, so Google knows what you want to appear as your logo. However, the description is not as necessary.

script type="application/ld+json">

{"@context": "http://schema.org/",
"@type": "Organization",
"url": "http://www.yourcompany.com/",
"logo": "http://www.yourcompany.com/logo.png"
}

If you use <a class="selected" data-selects="microdata">Microdata</a> schema you will have your description show up on your page you want that?

https://schema.org/logo

ACME Hotel Innsbruck

alt="hotel logo" />

A beautifully located business hotel right in the

heart of the alps. Watch the sun rise over the scenic Inn valley while

enjoying your morning coffee.

alt="Company name"/>

alt="image description" title="image tooltip"/>

Alt text is best when always used but you do not want to make it too long. Three words should suffice at most As far as a description goes under your logo that's a choice you in your designer have to speak about I would think it would look a little odd.

Keep in mind

"Each image should have an alt text. Not just for SEO purposes but also because blind and visually impaired people otherwise won’t know what the image is for. A title attribute is not required. It can be useful but in most cases, leaving it out shouldn’t be much of an issue."
