Internal link audit for Next.js and React sites.
JavaScript frameworks make it easy to ship content that users see but crawlers don't — links injected on the client, content rendered after hydration. RankForge crawls your Next.js site, flags what's only visible after JavaScript runs, and maps the internal links search engines can actually follow. No setup required.
The SEO problems Next.js and React sites run into
Client-rendered links crawlers miss
Internal links injected by JavaScript after load may never be followed by crawlers, silently cutting pages off from the link graph.
Content invisible without JavaScript
Pages that render their body client-side can look empty to a crawler, leaving text-based analysis title-only and rankings weak.
Inconsistent rendering strategies
Mixing SSR, SSG, and client rendering across routes means some pages are fully crawlable and others aren't — and it's hard to tell which without a crawl.
What the audit gives you
Why JavaScript frameworks complicate SEO
Next.js, React, Vue, and similar frameworks render much of the page in the browser. When done with server rendering or static generation, that's fine for SEO — the HTML arrives complete. But it's easy to ship routes where the meaningful content and internal links only appear after JavaScript executes. Search engines do render JavaScript, but not reliably or immediately, and anything that depends on user interaction to appear is effectively invisible to them.
The most common casualty is internal linking. A navigation or 'related content' block injected on the client can leave whole sections of a site unlinked from a crawler's point of view — the pages exist, but nothing a crawler follows points to them. RankForge fetches your pages and reports what's actually present in the crawled response, so you can see where rendering is hiding your structure.
How client rendering orphans your pages
If the links to a set of pages are only rendered client-side, those pages can become orphans in the eyes of search engines even though they're perfectly reachable for a human clicking through the app. This happens often with dynamically-generated routes, filtered list pages, and content loaded on scroll. The site feels complete; the crawlable link graph has holes.
A crawl that follows only what's in the delivered HTML reveals exactly which pages are cut off and which rendering choices are responsible — so you can move the critical links and content into the server-rendered output.
What to fix first on a Next.js site
Make sure your important content and internal links are in the server-rendered or statically-generated HTML, not injected purely on the client. Then map the structure: reconnect pages that rendering has orphaned, strengthen the clusters around your key routes, and add the contextual links that route authority where it matters. RankForge flags the rendering gaps and prioritises the internal-linking fixes with exact placement.

Frequently asked questions
Does RankForge render JavaScript when it crawls?expand_more
RankForge analyses the pages as delivered and flags content and links that depend on client-side JavaScript to appear — which is exactly the signal you need, because that's the content search crawlers are least likely to see reliably.
Does this work for React, Vue, or other SPA frameworks?expand_more
Yes. The same rendering and internal-linking issues apply to any client-rendered framework. RankForge crawls the public pages and shows what's reachable regardless of the framework behind them.
Do I need to install anything on my site?expand_more
No. RankForge crawls your public site from any URL — no plugin, app, theme change, or admin access required. It works the same way a search engine does.
Is it free?expand_more
Yes. Run a free internal-link audit with no account required, then create a free account for the full structural audit of up to 100 pages with the specific link recommendations.
