Crawlability, metadata, structured data, redirects and migrations.
Technical SEO is the part of search optimisation that developers control: whether pages can be crawled and indexed, whether each URL has one clear canonical version, and whether search engines can understand the content through metadata and structured data.
This path covers a practical checklist for Next.js and WordPress sites and a migration method for moving a site to a new host or domain without losing rankings. Both come from real launches and migrations.
Who it’s for: Developers responsible for launches, rebuilds and migrations.
Start with lesson 1: Technical SEO checklist for developers: Next.js and WordPress
A migration plan that protects rankings: inventory URLs, move files and database safely, run a serialization-safe search-replace, map 301 redirects, and tell Google about the move.
A practical guide to schema.org structured data with JSON-LD: which types still earn rich results, how to model articles, products, organisations, people and breadcrumbs, connecting entities with @id, generating it in WordPress and Next.js, and testing it.
The technical SEO work that belongs to developers, not marketers: crawlability, canonicals, metadata, structured data, sitemaps, redirects, pagination and status codes, for both WordPress and Next.js.
