My client redesigned their site. Once it went live, ALL of their rankings disappeared. Even branding. Help?

Does anybody know why this might happen? When we made the new site, we just changed the skins. The source code was the same, the content was the same.

Even when I search their brand name and their city, their URL won't show up.

When I search their URL into Google, it won't even pull up their homepage: it only pulls up /contact-us and some other subpages.

Any tips on what I should be looking out for?

I will check the robots.txt and header metatags as your skin might come with NOROBOTS defaults metatag.

Did you implement an SSL? A link to the website could also help us diagnose the issue. It could have been caused by numerous reasons.

Try using this extension, it's quite handy for highlighting issues.

Also, are you getting any issues highlighted in Search Console?
