You should try specifying cache revalidation inside the client call.

const data = await client.fetch(query, {}, {
  next: {
    revalidate: 86400,
  },
});

From Sanity's official plugin for Next: https://www.sanity.io/plugins/next-sanity#time-based-revalidation

@not-milo.tsx is see now that even after deploy the ssg content not change the cache is to strong

If you want to avoid caching on deployments you can manually disable it when triggering the redeploy, or you can append ?buildCache=false at the end of the deployment webhook.

where ?

Currently there's no way of doing it from automated ci/cd pipelines (see this discussion: https://github.com/vercel/vercel/discussions/8057#discussioncomment-3057196). You have to use a deploy webhook or do it manually from the dashboard.

You want to tell me that if I want to use ssg I need to rebuild in myself every day?

how I rebuild manually?

No, I'm trying to tell you that there's a better way. You can set up a build hook on Sanity that calls the Vercel api and rebuilds the website when an editor publishes new content. It's all automated, you don't have to do anything.

All you have to do to set it up is go to your Sanity dashboard and add a new webhook in the api section (https://www.sanity.io/docs/webhooks). And then you have to create a deploy hook from your Vercel dashboard, you'll find instructions here: https://vercel.com/docs/deployments/deploy-hooks.

Ok nice thank you!!!
