What Is Technical SEO?
Technical SEO refers to the behind-the-scenes work that helps search engines find, understand, and rank your website. While content and keywords speak to users, technical SEO speaks to search engines. It optimizes your website for quick loading, mobile device compatibility, and visibility best practices.
Think of it like your site’s infrastructure—if your content is the furniture, technical SEO is the foundation, wiring, and plumbing.
Crawlability and Indexability
Before a page can show up in search results, search engines must find and understand it. This process begins with crawling (discovery) and indexing (storage in the search engine’s database).
A few beginner-friendly basics:
- Your site should allow search engines to crawl pages via a robots.txt file.
- Important pages should not be blocked or marked with noindex tags.
- Use internal links to help bots discover pages.
Free tools like Google Search Console can show you which pages are indexed and if there are crawl issues.
Website Structure and Hierarchy
Good structure helps both users and search engines understand how your content is organized.
Tips for beginners:
- Use a clear hierarchy (Home > Category > Subpage).
- Keep URLs clean and descriptive (e.g., /blog/technical-seo-vs-onpage-seo).
- Add internal links to related content.
- Use breadcrumbs to help navigation.
The easier it is to find and understand your pages, the better your SEO foundation.
Site Speed and Core Web Vitals
Beyond user experience, loading speed impacts search engine rankings. Search engines prefer pages with fast load times.
Core Web Vitals are a set of performance metrics:
- LCP (Largest Contentful Paint): Measures loading speed.
- FID (First Input Delay): Measures interactivity.
- CLS (Cumulative Layout Shift): Measures visual stability.
Use tools like:
Mobile-Friendliness
With mobile-first indexing, search engines evaluate your site as if it’s being viewed on a smartphone.
Make sure your site is:
- Responsive (adapts to different screen sizes)
- Easy to navigate on mobile
- Free of pop-ups or overlapping elements
Check using Google’s Mobile-Friendly Test.
XML Sitemaps and Robots.txt
Two key files help search engines understand your site:
- XML Sitemap: A list of important URLs you want indexed. Submit it in Google Search Console, Bing Webmaster Tools, and Yandex Webmaster Tools.
- Robots.txt: A file that tells bots which pages or folders to avoid crawling.
Both files live in your root domain and are easy to generate using tools like Yoast SEO or Screaming Frog.
HTTPS and Site Security
HTTPS (SSL encryption) protects your users and signals trust to search engines.
If your URL starts with https:// and shows a padlock icon, you’re good. If not, it’s time to upgrade.
Many hosting providers include a free SSL certificate.
How to Do a Basic Technical SEO Audit
You don’t need to be a tech wizard to start checking your site’s health.
Step 1: Google Search Console
Look for crawl errors, indexing issues, or manual actions.
Step 2: PageSpeed Insights
Check performance scores for desktop and mobile.
Step 3: Screaming Frog (Free Version)
Crawl up to 500 URLs to spot issues like broken links or duplicate metadata.
These small checks can uncover big opportunities.
When to Go Deeper
Once you’re comfortable with the basics, you can explore more advanced concepts like:
- Canonical tags (avoid duplicate content issues)
- Structured data (enhance your listings with schema)
- Pagination handling (for blog archives and eCommerce sites)
But for now? Focus on speed, structure, and crawlability.
