Simply put, technical SEO is about improving the technical aspects of a website to increase its performance and visibility in search engine results. You already know what SEO is – it focuses on using the right keywords to attract search engines like Google. However, technical SEO goes a step further. It focuses on the backend, server, and code of a website to ensure that everything runs smoothly. Optimizing elements like page speed, mobile responsiveness, secure connections, and proper indexing help search engines better understand your site and improve your rankings.
In this post, we’ll explore the basics of technical SEO. While “basics” and “technical” may seem contradictory, understanding the key technical parts can be the difference between a website that ranks highly and one that doesn’t show up at all. Technical SEO may seem complicated, but we’ll explain it in simple terms. Knowing which areas to focus on – or which areas your developer should handle – ensures that your website’s foundation supports strong SEO, better user experience, and faster load times.
What is Technical SEO?
Technical SEO focuses on improving your website so that it is easier for search engines to find, interpret, and store your content.
It also covers aspects of user experience, such as improving website speed and ensuring easy usability on mobile devices.
When done correctly, technical SEO can increase your visibility in search engine results.
In this guide, you will explore the key principles and proven strategies for optimizing your website for technical SEO.
Let’s get started.
Why is technical SEO important?
Technical SEO can determine the success of your SEO efforts.
If search engines can’t access your site’s pages, they won’t appear in search results – even if your content is highly valuable.
This can lead to lost website traffic and reduced business opportunities.
In addition, search engines consider website speed and mobile responsiveness as ranking factors.
If your pages load slowly, visitors may leave quickly, which can indicate a poor user experience. Such behavior can cause search engines to lower your rankings.
To fully understand technical SEO, we need to focus on two main processes: crawling and indexing.
What Are the Technical SEO Best Practices?
1. Create an SEO-Friendly Site Structure
Site structure defines how your website pages are organized and linked. An SEO-friendly structure helps search engines crawl, understand, and rank your content effectively while providing an intuitive experience for visitors.
An optimized site architecture ensures fast crawling, proper distribution of ranking authority, and an improved user experience.
A strong site structure follows a logical hierarchy, organized internal links, consistent URLs, and a minimum click depth:
- Clear hierarchy: Home page → category pages → subcategories → individual pages.
- Logical internal linking: Improves indexing and content discoverability.
- Consistent URL patterns: Example: example.com/category-name/product-name.
- Minimum click depth: Main pages should be accessible in a few clicks.
Start by mapping the hierarchy from the homepage to the main categories and subpages. Make sure important pages are reachable within three clicks to make navigation and crawling efficient.
2. Implement semantic HTML correctly
Semantic HTML uses HTML5 tags that define the meaning of content.
- <header>: Holds site title, logo, and navigation links.
- <nav>: Contains main navigation menus.
- <main>: Wraps core page content.
- <section>: Groups related content under headings.
- <article>: Represents individual posts or standalone content.
- <aside>: Holds supplementary info like sidebars.
- <footer>: Contains contact info, links, or copyright.
Run a Google Lighthouse audit through Chrome DevTools under “Best Practices” and “Accessibility” to detect incorrect HTML usage. Test structured HTML using Google’s Rich Results Test to see how search engines interpret your content. Proper semantic HTML increases the likelihood of rich results, featured snippets, and voice search visibility.
3. Maintain high-level website security
Website security protects your site from attacks, data breaches, and unauthorized access. Key security measures include HTTPS, secure HTTP headers, and regular monitoring.
Install an SSL certificate from a trusted CA or use a free option like Let’s Encrypt to enable HTTPS. Verify HTTPS using tools like Search Atlas Site Audit’s Page Explorer to find mixed content issues.
Set HTTP headers to block vulnerabilities such as Content-Security-Policy, Strict-Transport-Security, and X-Content-Type-Options. Use SecurityHeaders.com to scan headers, and use Google Search Console’s Security Report to identify malware or security issues.
4. Submit an XML Sitemap to Google
An XML sitemap lists all the URLs on your site, which helps search engines find, crawl, and index your pages effectively. Sitemaps provide metadata such as last update dates and priority.
WordPress users can generate sitemaps through Yoast SEO. For custom sites, use a free tool like XML-Sitemaps.com.
Check sitemap coverage:
- Open example.com/sitemap.xml in a browser.
- Include all main pages except duplicate or irrelevant URLs.
- Check sitemap inclusion in Search Atlas Page Explorer (the “In XML SITEMAP” column).
Submit your sitemap to Google Search Console: Index → Sitemap → Enter Sitemap URL → Submit. CMS-generated sitemaps are updated automatically; static sitemaps should be regenerated and resubmitted periodically.
5. Follow proper Robots.txt guidelines
The robots.txt file provides search engine crawling instructions, prevents unnecessary crawls, and protects sensitive pages.
- Visit https://example.com/robots.txt to review the guidelines.
- Make sure no important pages are blocked.
- Use Search Atlas Site Audit to find crawlability issues.
6. Use Meta Robots Tags Properly
Meta robots tags control the crawling and indexing of individual pages. Proper implementation improves SEO and ensures that Google indexes the right content.
- index, follow: Public pages, such as blog posts or landing pages.
- noindex, follow: Pagination or old pages that you don’t want indexed.
- noindex, nofollow: Private pages, such as login portals or test environments.
Check the HTML source or meta robots tags using Google Search Console’s URL Inspection tool. Avoid conflicts with canonical tags. Regularly review Google Search Console’s Page Indexing Report.
7. Implement pagination correctly
Pagination divides large pieces of content into multiple pages, especially for blogs, categories, or product listings. Proper pagination ensures indexed pages and avoids ranking drops.
- Use self-canonical tags for paginated pages: <link rel=”canonical” href=”https://example.com/category/page-2/”>
- Allow paginated pages to be indexed; avoid noindex unless necessary. Indexing via Google Search Console
8. Fix Internal Linking Errors
Internal linking errors disrupt navigation and SEO. Use Search Atlas Site Audit to find broken links, redirect chains, and orphan pages.
- Update broken or outdated links to improve URLs.
- Remove redirect chains.
- Link orphan pages from high-authority pages.

9. Find and repair broken links
Broken links lead to 404 errors and hurt the user experience. Use Search Atlas Site Audit to find:
- Internal broken links
- External dead links
- Server errors
Fixation strategies:
- Internal links → Update or 301 redirect.
- External links → Replace or remove.
- Deleted pages → 301 redirect to relevant content.
Regular audits prevent problems and maintain a strong link structure.
10. Implement breadcrumb navigation
Breadcrumbs show users and search engines the position of a page in a hierarchy. They improve navigation, crawlability, and user experience.
- Follow the site hierarchy: Home > Category > Subcategory > Page.
- Use anchor links and maintain consistency.
- Check Google Search Console’s breadcrumb report for errors.
11. Optimize faceted navigation
Faceted navigation allows filtering of content by attributes. Improperly managed faceted pages can create duplicate URLs and dilute SEO signals.
- Use canonical tags: <link rel=”canonical” href=”https://example.com/category/”>
- Disallow low-value filters in robots.txt.
- Implement noindex to filter out pages that should not appear in search results.

12. Increase page speed
Page speed affects user engagement, conversions, and rankings. Use Google PageSpeed Insights to identify slow-loading elements.
Optimize by:
- Enable browser caching: cache-control: max-age=31536000
- Minify HTML, CSS, JS
- Use a CDN
- Reduce server response time
13. Optimize Google Core Web Vitals
Core Web Vitals measure loading, interactivity, and visual stability. Improving them improves rankings and user experience.
- CLS: Prevent layout shifts by using fixed dimensions for images and ads.
- FID: Reduce JS execution time and defer non-essential scripts.
- LCP: Optimize hero images, enable lazy loading, and use a CDN.
Monitor with Search Atlas Site Audit to track PSI issues and page experience improvements.
14. Ensure mobile responsiveness
A responsive site adapts to all screens, improving mobile-first indexing.
- Test with Google Lighthouse or Chrome DevTools device mode.
- Use flexible grids, responsive images with srcset, and appropriate viewport meta.
15. Make your website accessible
Accessibility ensures that all users, including users with disabilities, can navigate your site. Google considers accessibility as part of the page experience signals.
- Use Lighthouse to detect ARIA attributes for images, missing language tags, color contrast, keyboard navigation, and alternative text.
Conclusion
An essential part of any digital marketing strategy is developing a technical SEO checklist. Therefore, every business owner or brand manager should devote a decent amount of time to optimizing the technical SEO of their website, as the benefits far outweigh the initial difficulties of understanding the concepts and implementing the techniques. When handled properly, you won’t have to worry about it much, except when you plan to conduct regular website audits.
