Technical SEO, defined

The infrastructure underneath every ranking.

In practice

The website implementation is tested across templates instead of assuming that one successful URL represents the whole platform.

Why it matters

It removes implementation barriers that can weaken otherwise strong products and content.

Technical SEO

Optimising crawling, indexing, rendering, architecture, performance and technical signals.

Ana says: Technical SEO should remove barriers, not create 200 rows nobody implements.

Site Architecture

The way website pages, categories and relationships are organised.

Faceted Navigation

A filtering system that narrows listings by attributes such as size, brand, colour or price.

JavaScript SEO

Ensuring JavaScript-based content can be crawled, rendered, linked and indexed correctly.

Ana says: “Google can render JavaScript” is true. So is “people can run marathons”. Context matters.

Server-Side Rendering (SSR)

Generating page HTML on the server before delivering it to the browser.

Client-Side Rendering (CSR)

Generating much of the page in the browser after JavaScript executes.

Mobile-First Indexing

Google primarily using the mobile version of a page for indexing and evaluation.

HTTPS

The secure version of HTTP, encrypting communication between browser and server.

CDN

A distributed network serving website resources from locations closer to users.

Caching

Temporarily storing resources or responses so future requests can be served faster.
