How we ship rankings on Next.js

No matter the platform — these are the diagnostics we ship to production. Mono outputs are real Lighthouse / Search Console signals from recent client engagements.

Render strategy per route

The App Router lets a single app mix static, dynamic and incremental rendering route by route. Marketing pages ship as SSG, a 100k-SKU catalog runs on ISR with on-demand revalidation so a price change invalidates one path instead of rebuilding, and the dashboard streams. Most Next.js SEO problems we inherit are one wrong export — a `force-dynamic` on a page that should have been static, costing TTFB on every crawl.

Metadata as data

`generateMetadata` runs on the server with the same data the page renders from, so titles, canonicals, OG tags and JSON-LD are derived rather than hand-maintained — and cannot drift from the content. It is also async, so metadata is fetched in parallel with the page rather than blocking it.

Streaming without CLS

Suspense boundaries let the shell paint while slow data resolves, which moves LCP forward without the layout shift that usually follows. The discipline is reserving the space: a boundary whose fallback has different dimensions to its content trades a better LCP for a worse CLS, and Google measures both.

Build pipeline

How a Next.js build ships

Every engagement runs the same five-stage pipeline. Senior engineer at every stage, status visible in your shared Notion the entire time.

  1. Audit the render exports

    $ next build --debug

    Every route classified as static, ISR or dynamic, with the reason recorded. This alone usually recovers most of the TTFB on an inherited build.

  2. Move the catalog to ISR

    $ revalidatePath("/p/[slug]")

    On-demand revalidation wired to the CMS webhook so a content change invalidates its own path and nothing else.

  3. Derive metadata from the data layer

    $ next lint --rule seo

    generateMetadata replaces hand-maintained tags, so canonical, OG and JSON-LD cannot drift from what the page renders.

  4. Budget the boundaries

    $ lighthouse --preset=mobile

    Suspense fallbacks sized to their content, then LCP and CLS measured on real mobile hardware, not on a laptop throttle.

FAQs

Questions about Next.js SEO engineering

Quick answers to the things buyers ask before signing.

Should my Next.js pages be SSG, SSR or ISR?
Per route, not per app — that is the whole point of the App Router. Marketing pages are static. A large catalog is ISR with on-demand revalidation, so a price change invalidates one path rather than triggering a full rebuild. Only genuinely per-request pages (a logged-in dashboard, a personalised feed) should be dynamic. Most of the Next.js builds we inherit have a `force-dynamic` sitting on a page that should have been static, and it is costing TTFB on every crawl.
Does the App Router hurt or help SEO versus the Pages Router?
It helps, provided you use it. Server Components keep data-fetching off the client, `generateMetadata` derives tags from the same data the page renders, and streaming gets the shell painted sooner. The failure mode is porting Pages Router habits across — marking everything a Client Component, which puts you back to shipping the whole render to the browser.
How do you stop ISR serving stale pages to Google?
By making revalidation event-driven rather than time-based wherever the CMS can emit a webhook. `revalidatePath` on publish means the change is live on the next request instead of after a timer. Time-based `revalidate` is the fallback for sources that cannot notify, and then the interval is set from how often the data actually changes, not from a default someone copied.
Can you work on our existing Next.js codebase?
That is most of what we do here. The first pass is an audit of the render exports across every route with the reason for each recorded, because that alone usually recovers most of the TTFB. We work in your repo, in PRs your team reviews.
