Next.js 15 and SEO Optimization

Next.js 15 arrived with fantastic features to elevate the speed and search engine optimization (SEO) of your modern web projects. In this post, we will look at how to set up the technical SEO structure.

1. Using the Metadata API Next.js provides a robust Metadata API to define dynamic meta tags at the page level. By using the `generateMetadata` function, you can dynamically build page titles, descriptions, and Open Graph data for each blog post.

2. Structured Data (JSON-LD) Structured data in JSON-LD format is crucial to help search engines index your page accurately. Adding an `Article` schema for blog posts or an `FAQPage` schema for FAQ subpages ensures you rank in Google rich snippets.

3. Image Optimization Next.js's built-in `Image` component automatically formats images to WebP/AVIF, sizes them, and prevents layout shifts. This is one of the most critical steps to achieve a 100/100 Lighthouse performance score.
