What is Technical SEO?

Technical SEO refers to all the behind-the-scenes optimizations that need to happen on a website for it to perform well and surface content properly to search engines.

  • Secure using HTTPS
  • Accessible to search bots
  • Cleanly coded
  • Easy to crawl, index and understand

Technical SEO establishes the infrastructure for content to thrive and ensures search engines can efficiently crawl a site to accurately rank pages.

Why Technical SEO Matters

With search algorithms placing more emphasis on site speed, security and technical components, foundational technical SEO is mission critical.

Here are key reasons why technical site factors influence organic performance:

Page speed impacts rankings – Faster sites can achieve higher rankings, especially on mobile. Page speed is a ranking factor.

Improves user experience – Faster load times keep visitors on site longer. Technical upgrades enhance UX.

Bolsters security – HTTPS encryption provides security. robost.txt and other tools protect from threats.

Increases indexation – Clean technical builds help search bots crawl larger portions of a site.

Technical SEO brings all these elements together into a cohesive, optimized website capable of ranking well.

Steps for Optimizing Technical SEO

Here are key steps sites should take to optimize the technical foundations:

Conduct a technical site audit – Crawl your site using tools like ScreamingFrog to identify technical issues.

Speed up your site – Compress images, minify CSS/JS, implement caching, upgrade hosting, CDNs and more. Use PageSpeed Insights.

Migrate to HTTPS – Obtain an SSL certificate and switch site to HTTPS, including all pages and assets.

Mobile optimization – Make site design fully responsive for all device widths and resolutions. Test on real mobile devices.

Optimize for Core Web Vitals – Improve largest contentful paint, cumulative layout shift and first input delay.

Enhance crawlability – Update XML sitemaps, eliminate blocking resources, fix crawling errors. Submit new pages in Search Console.

Clean up code – Refactor sloppy code. Validate HTML, CSS and fix errors. Eliminate excessive redirects.

Choose SEO-friendly CMS – If rebuilding, select a crawler-friendly CMS like WordPress with flexibility.
