In the grand architecture of your website, your internal pages and resources are the components that make up the entire structure. This includes not just the visible HTML pages, but also all the supporting files like CSS, JavaScript, images, and PDFs. A comprehensive technical SEO strategy involves auditing every one of these internal assets to ensure they are performant, accessible, and optimized for search engines. A healthy internal site is a prerequisite for any successful external SEO effort.
Think of your website as a car. The HTML pages are the chassis and body, but the CSS, JavaScript, and images are the engine, wiring, and paint. For the car to perform at its best, every single component needs to be in perfect working order. For a deep dive into this topic, check out this beginner’s guide to technical SEO from Ahrefs.
