meta description about pwacompat HOT 7 CLOSED

I could do this but I'm not sure of the added value. I suspect most sites that are reading this kind of meta from the HTML itself aren't running the page's JS—think e.g., sharing a link on Twitter.

Is there another reason why this might be useful?

The main reason is to avoid this Lighthouse's warning:

I really believe that most crawlers/etc are not going to run page JavaScript just to read your site's meta tags.

So while it might make Lighthouse happy, I suspect this change won't actually improve your SEO.

I understand your point, but I'm not sure it would be a bad thing. You could just check if there is a meta description already and add one based on manifest if not.

Just as theme_color, I don't like to have to duplicate it on my HTML head.

Unlike <title> (under some circumstances) a <meta> description isn't required in HTML. If you don't need it, should you add it just to appease the Lighthouse tool?

I haven't googled it but I'm quite sure Google can index script-generated content, however if Google saw the same <meta> description across several pages then the site-owner may start worrying about "SEO penalties" due to duplicate content.

Personally I don't think this is a good default for PWACompat.

Sorry @hnordt but I also don't think this is worth including.

PWACompat is not intended to help with search indexability. I've had #22 filed and I'll mention this as part of resolving that issue.

Thank you for having a look at it @samthor. I agree with you.
