What Is Technical Search Engine Optimisation?
Technical SEO is the practice of optimizing a website’s infrastructure so search engines can efficiently crawl, index, and understand your content. It focuses on how your site is built rather than what’s on the page. The audit evaluates SEO-critical signals that influence indexing, interpretation by search engines, and visibility in both traditional and generative search results.-
Website Crawlability
Ensures search engine bots can access your pages. Involves optimizing:robots.txt- XML sitemaps
- URL structure
-
Indexing
Making sure search engines store your pages correctly in their index. Prevent accidental “noindex” tags or duplicate content issues. -
Site Speed & Performance
Faster sites rank better and reduce bounce rates. Involves:- Image compression
- Caching
- Minimizing CSS/JS
- Using CDNs
-
Mobile Optimization
Google uses mobile-first indexing. Ensures the site works smoothly on mobile devices. -
Security
HTTPS encryption is a ranking factor. Prevents browser warnings that hurt trust and traffic. -
Structured Data (Schema Markup)
Helps search engines understand content more clearly. Enables rich results (e.g., star ratings, FAQs, recipes). -
Site Architecture
A clean, logical structure improves crawling and UX. Includes internal linking and using breadcrumbs. -
Canonicalization
Prevents duplicate content by telling Google which version to index.
