Content on desktop and mobile

[ASKHANUMANTHAILAND]

My website hasn't using responsive design and separate domain for mobile optimize, But we using dynamic serving for mobile version, Read more about dynamic serving here

So our website must different design for both version, And then what would be happen in term of SEO if our website hasn't show the same content as desktop but still align with the main content,  Such as Desktop has longer content compare to mobile version or Desktop has long H1 but mobile is shorter than.

What should we do for this case and how to tell Google Bot.

Hi Johannes,

I've understood your question to be about how to treat a site which uses dynamic serving for mobile content. Is this correct?

If your site keeps the same URLs for mobile and desktop versions, but serves different content based on user agent, then you will simply need to include a Vary-HTTP header. You can learn more about that here.
