Across our Sanity projects, the most reusable technical decision was not a clever GROQ query. It was defining the content before defining the pages.
For Kasada, Orb, Contextual AI, Zenity, Hy-Vee, Newfront, and our own M8 site, the schema determined whether content could be filtered, cross-linked, migrated, previewed, and rendered beyond one page template. The patterns below come from our documented Sanity implementations, where the same platform supported marketing sites, internal tools, legacy migrations, and multi-site content operations. Structured content stores meaning and relationships independently from its final presentation. A case study remains a case study whether it appears as a card, a hero, or an entry in a filtered index.
That distinction sounds small, but it changes how a system responds to redesigns. A schema named after a URL or page layout tends to inherit assumptions from that interface. When the layout changes, the schema often has to change with it.
We instead model stable entities. Authors, clients, technologies, and sectors become documents rather than repeated strings. Other content references those documents. This makes filtering, cross-linking, and resurfacing possible without adding another manually maintained field for every new use.
Editors still need control, but not necessarily control over every visual property. We use a fixed set of design system blocks so editors can determine sequence and emphasis while the application owns spacing, color, and responsive behavior. On M8, modular sections can be reordered and recombined while preserving the exposed grid and visual system.
The tradeoff is intentional. Editors cannot construct arbitrary layouts inside the Studio, but the pages they publish remain inside the tested design system.
A CMS migration is primarily a mapping problem.
Our process begins with an audit of the legacy archive. We decide what should carry over, what needs rewriting, and what should be retired. Only after those decisions are reflected in the target content model do we move the content.
For Contextual AI, this meant leaving the legacy system with the existing content intact while introducing a model capable of supporting what came next. The archive survived, but the limitations of its previous representation did not have to become permanent features of the new schema. Starting with an export reverses that sequence. It encourages the team to reproduce the source CMS inside Sanity, including page-shaped records, duplicated strings, and fields that existed only to satisfy an old template.
A useful migration plan therefore describes both sides of every mapping: what the legacy field represented and which new document, reference, or structured field should own that meaning. The migration script should implement an already settled model, not become the place where the model is improvised.
Sanity uses GROQ to query and transform structured content. GROQ is expressive enough to compensate for many schema problems, which is exactly why query complexity deserves attention.
Our rule of thumb is concrete: if rendering one card requires 3 nested joins, inspect the schema before tuning the query. The issue may be that data used together is modeled too far apart, or that presentation concerns have leaked into the content structure.
Portable Text follows the same principle. We treat it as structured rich text, not stored HTML. The application decides how the structure should render on a web page, in a feed, or for a machine reader. That avoids maintaining separate copies of the same body for each surface.
This becomes increasingly important when content serves both people and machines. On Kasada, structured content, explicit references, and machine-readable markup supported enterprise buyers and automated consumers from the same model. The structure was part of the architecture, not something added later through a plugin.
On M8, we also use Sanity Typegen to generate TypeScript types from GROQ queries. This keeps the relationship between the content model, query result, and application code visible to the type system instead of relying on manually maintained interfaces.
A customized Sanity Studio is a frontend application for a specific group of users. Its information architecture, input components, previews, and validation deserve the same attention as the public interface.
The Hy-Vee KidsFit implementation is a useful example. Editors add a YouTube URL in Sanity, and the integration retrieves the video thumbnail, title, and description through the YouTube API. GROQ also powers dynamic resource filters on the site.
That input does more than store a URL. It turns a repeated editorial task into a consistent integration point. Editors spend less time transferring metadata manually, and the public interface receives a predictable content shape.
For Zenity, the structured model gave the marketing team enough flexibility to update content and create pages without developer support. Sanity's collaborative editing also allowed multiple team members to work simultaneously. Live previews on M8 complete the feedback loop by showing creators how changes will appear before publication. If an editor regularly needs a developer to interpret a field or publish a routine page, we treat that as a modeling or Studio design problem.
Our Sanity sites commonly use Next.js on Vercel. Server Components read from Sanity directly, and publication triggers on-demand revalidation. Editors see updates without waiting for a full rebuild, while readers receive static performance.
That architecture separates publishing from deployment, but it does not eliminate maintenance. A customized Sanity Studio has dependencies, upgrades, custom components, and its own release surface. Teams choosing Sanity should account for that application alongside the public site.
This leads to a practical selection criterion. Sanity fits when the content contains stable entities and relationships worth preserving, editors benefit from a purpose-built workflow, and the team can maintain the Studio as software. If the main requirement is a hosted editing interface with nothing to customize or upgrade, a simpler CMS may be a better fit.
When those conditions do hold, the durable asset is not any individual page. It is a content model that can survive the next layout, integration, publishing workflow, and consuming application.
