SEO

Directories are a true cheat code for SEO, don't sleep on it!

Everything you need is already pre-filled from your /data/config/metadata.js file:

• title

• description

• type

• url

• OpenGraph

• Twitter Card

And so on ...

You can customize these metadata by calling genPageMetadata function on your page:

app//categories/[slug]/page.tsx

import CategoryLayout from "@/app/layouts/CategoryLayout";
import { genPageMetadata } from "@/app/seo";
import { metadata } from "@/data/config/metadata";
import prisma from "@/lib/prisma";

export async function generateMetadata({
  params,
}: {
  params: { slug: string };
}) {
  const categoryData = prisma.category.findUnique({
    where: { slug: params.slug },
    select: {
      name: true,
      slug: true,
    },
  });
  const category = await categoryData;
  if (!category) {
    return genPageMetadata({
      title: "Category not found",
    });
  }
  return genPageMetadata({
    title: `Best ${category.name} ${metadata.productLabel}s`,
    description: `Find all the best ${category.name} ${metadata.productLabel}s.`,
    url: `/categories/${category.slug}`,
  });
}

export async function generateStaticParams() {
  const categoriesData = prisma.category.findMany();
  const categories = await categoriesData;
  return categories.map((category) => ({ slug: category.slug }));
}

export default function Category({ params }: { params: { slug: string } }) {
  return <CategoryLayout slug={params.slug} />;
}

genPageMetadata can't be called on a client page ("use client"), keep your pages file server side rendered and build a client layout.

Indexing

• /app/robots.ts file will help crawling robots (Google, Bing) understand what pages you want to be indexed or not:

/app/robots.ts

import { MetadataRoute } from "next";

export default function robots(): MetadataRoute.Robots {
  return {
    rules: {
      userAgent: "*",
      allow: "/",
      disallow: [
        "/dashboard*",
        "/terms",
        "/privacy",
        "/stats",
        "/opengraph-image?",
      ],
    },
    sitemap: `${process.env.NEXT_PUBLIC_APP_URL}/sitemap.xml`,
    host: process.env.NEXT_PUBLIC_APP_URL,
  };
}

Do not forget to claim your domain ownership on Google Search Console.

• /app/sitemap.ts file adds automatically every new product or category to the sitemap so you don't have to request them manually, you can add your own logic if you wan't more pages to be added:

app/sitemap.ts

import { MetadataRoute } from "next";
import prisma from "@/lib/prisma";

export default async function sitemap(): Promise<MetadataRoute.Sitemap> {
  const siteUrl = process.env.NEXT_PUBLIC_APP_URL;

  const categories = await prisma.category.findMany({
    ...
  });

  const categoryRoutes = categories.map((category) => {
    const lastModified = category.products[0]?.createdAt || category.createdAt;
    return {
      url: `${siteUrl}/categories/${category.slug}`,
      lastModified: lastModified.toISOString().split("T")[0],
    };
  });

  ...

  const mainRoute = {
    url: `${siteUrl}/`,
    lastModified: latestproduct
      ? latestproduct.createdAt.toISOString().split("T")[0]
      : new Date().toISOString().split("T")[0],
  };

  return [mainRoute, ...categoryRoutes, ...productRoutes];
}
