Add JSON-LD structured data — Replit

Without JSON-LD, Google and AI crawlers have to guess what your page represents. With it, you get rich results in Google and clean entity extraction in ChatGPT and Claude.

The prompt for Replit

Copy and paste this into your Replit chat exactly as-is.

In Replit, ask the Replit Agent to make these exact changes across the project:

Add JSON-LD structured data

1. Add a <script type="application/ld+json"> in <head> with an Organization (or WebSite) schema including name, url and logo.
2. On article/blog pages, add an Article or BlogPosting schema with headline, author, datePublished and image.
3. For FAQ-style pages, add an FAQPage schema with mainEntity[].question / acceptedAnswer pairs.

Why this matters

JSON-LD is how you tell search engines "this page is an Article, by this author, published on this date, about this topic" in machine-readable form. Google uses it for rich results — the expanded snippets, star ratings, and FAQ accordions you see in search. AI crawlers use it for citation attribution.

The effort is low: one JSON block in the head, or a Next.js helper that emits it. The upside is real: rich results get 15-30% more clicks than plain results, and AI citations with proper attribution drive referral traffic directly.

Start with Organization on your homepage, Article on every blog post, BreadcrumbList on sub-pages, FAQPage where you have FAQ sections. Those four cover 90% of what most SaaS and content sites need.

Common mistakes to avoid

error_outlineShipping invalid JSON — Google silently ignores broken schema.
error_outlineAdding schema for content that does not exist on the page (e.g., Review schema without visible reviews) — counts as spam.
error_outlineMissing required fields — Product without price, Article without headline, fails validation.
error_outlineDuplicating content in microdata and JSON-LD, triggering "duplicate structured data" warnings.

How to verify the fix worked

check_circlePaste the page URL into https://validator.schema.org/ — no errors.
check_circlePaste into Google Rich Results Test (https://search.google.com/test/rich-results) — must show the expected result type.
check_circleView source and confirm the JSON-LD block is in the HTML, not injected by JS after load.
check_circleIn Google Search Console → Enhancements — your schema types appear within a week.

Frequently asked questions

Microdata vs RDFa vs JSON-LD — which should I use?expand_more

JSON-LD. Google explicitly recommends it. It is cleaner, does not clutter your HTML, and is easier for AI parsers.

Can I have multiple JSON-LD blocks on one page?expand_more

Yes. Common pattern: Organization in root layout, Article on the specific page, BreadcrumbList in a layout. Each in its own script tag.

Will schema directly improve rankings?expand_more

Not a direct ranking factor, but it unlocks rich results which get more clicks. CTR is an indirect signal.
