What Is Technical SEO?

Technical SEO, in its essence, is about making your website accessible, understandable, and credible to search engines. It’s a comprehensive approach that includes optimizing your site’s structure, ensuring its pages can be crawled and indexed, enhancing its speed, and securing it with HTTPS. Unlike other SEO strategies that focus on content creation and link building, technical SEO delves into the nuts and bolts of your website, ensuring that the digital facade your business presents to the world stands on a solid foundation.

I recall an instance from my early days in digital marketing when a client’s meticulously crafted content strategy was failing to yield results. The culprit? A web of technical SEO issues, from broken links to unoptimized images. Addressing these not only catapulted their site up the search engine results pages (SERPs) but also magnified the effectiveness of their content and link-building efforts. This was my epiphany: without a robust technical SEO strategy, even the most compelling content can languish in obscurity.

Why Is Technical SEO Important?

Technical SEO is the bedrock upon which all other SEO strategies rest. In a digital age where the first point of contact between a business and its potential customer is often through a Google search, the importance of technical SEO cannot be overstated. It ensures that search engines can crawl your site without hindrances, index your content correctly, and rank your site for relevant queries. Moreover, it significantly enhances user experience, a factor that search engines increasingly prioritize. In essence, neglecting technical SEO is akin to building a state-of-the-art skyscraper on quicksand.

An enlightening study by Backlinko underscores this, revealing a strong correlation between sites that excel in technical SEO aspects, like site speed and mobile-friendliness, and higher rankings in SERPs. The message is clear: in the competitive arena of online visibility, excellence in technical SEO is not optional; it’s imperative.

How to Do Technical SEO

Embarking on technical SEO can seem daunting, but it can be distilled into eight fundamental pillars. Each is a critical cog in the machinery that ensures your website operates smoothly and is favorably viewed by search engines.

1. Crawlability

Without crawlability, a website is invisible to search engines. This is about ensuring that search engine bots can navigate through your site, discover content, and understand its structure. Implementing a robots.txt file and ensuring it doesn’t inadvertently block critical pages is a foundational step. Moreover, using tools like Google Search Console to monitor and fix crawl errors can significantly enhance your site’s visibility.

Insider Tip: Regularly audit your site for broken links and improper redirects. These can severely impede crawlability and, by extension, your site’s SEO performance.

2. Indexability

Crawlability and indexability are two sides of the same coin. Once your site is crawlable, you must ensure that search engines can index your pages. Utilizing the “noindex” tag judiciously ensures that only your site’s most valuable content is indexed, keeping the clutter out of search engines and improving your site’s relevance and authority.

3. Mobile-Friendliness

In today’s mobile-first world, a site that isn’t optimized for mobile is a site that’s set up for failure. Google’s mobile-first indexing is a testament to this shift. Ensuring your website is responsive and offers a seamless experience across all devices is no longer optional; it’s a necessity.

4. Site Speed

Site speed is a direct ranking factor. In an age of instant gratification, a slow website is the fastest way to lose visitors. Tools like Google PageSpeed Insights offer valuable insights into your site’s performance and actionable recommendations to improve speed across desktop and mobile.

5. Site Architecture

A well-structured site is easy for users to navigate and for search engine bots to crawl. A logical hierarchy, clean categorization, and a straightforward navigation menu contribute to a site’s usability and SEO. Employing breadcrumb navigation can further enhance site architecture, providing clear paths for users and bots alike.

6. URL Structure

Keeping URLs simple, descriptive, and consistent helps both users and search engines understand the content of a page at a glance. Avoiding excessively long URLs, using hyphens to separate words, and including relevant keywords can significantly impact your site’s SEO performance.


Security is a top priority for both users and search engines. Migrating from HTTP to HTTPS is crucial for protecting your site’s data integrity and confidentiality. It’s a clear signal to your visitors that their safety is taken seriously, an aspect that can enhance trust and credibility.

8. Structured Data

Structured data, or schema markup, is about providing search engines with explicit clues about the meaning of a page’s content. It’s a way to enhance your listings in search results (think rich snippets) and can significantly boost click-through rates. Implementing structured data correctly can be a game-changer, making your content not just visible but also compelling in SERPs.

Technical SEO Tools

The complexity of technical SEO necessitates a suite of tools to diagnose, monitor, and enhance various aspects of your site’s technical health. Here are some indispensable tools in the arsenal of a technical SEO practitioner:

Google Search Console

A non-negotiable tool for anyone serious about SEO. It offers a wealth of information about your site’s performance in Google search, including issues related to crawlability, mobile usability, and security.

Google PageSpeed Insights

This tool provides detailed reports on your site’s performance on both desktop and mobile platforms, along with suggestions for improvement. It’s invaluable for identifying and remedying site speed issues.

Google Mobile-Friendly Test

A quick way to assess your site’s mobile usability. Given the importance of mobile optimization, this tool is essential for ensuring your site is up to par with Google’s mobile-first standards.

Google Structured Data Testing Tool

An essential tool for testing and validating your structured data implementation. It helps identify errors in your schema markup, ensuring your efforts in enhancing your listings in SERPs pay off.

Ahrefs Webmaster Tools

While not a Google tool, Ahrefs offers a comprehensive suite of functionalities, including site audits that can uncover a plethora of technical SEO issues, from broken links to issues with content quality.

Technical SEO Best Practices

Adhering to best practices in technical SEO is about maintaining a proactive stance towards your site’s technical health. Here are some critical practices to incorporate:

1. Fix Crawl Errors

Regularly monitor Google Search Console for any crawl errors and address them promptly. This ensures that search engines can access and index your content without issues.

2. Optimize Your Sites Structure and Navigation

Ensure your site is logically organized and easy to navigate. A clear hierarchy and intuitive navigation not only enhance user experience but also aid search engines in understanding your site’s structure.

3. Use a Logical URL Structure

Adopt a URL structure that is simple, logical, and keyword-rich. This enhances clarity for both users and search engines, contributing positively to your site’s SEO.

4. Use Canonical Tags

Employ canonical tags to handle duplicate content issues. This tells search engines which version of a page to prioritize, preventing them from splitting ranking signals across multiple similar pages.

5. Use an XML Sitemap

Submit an XML sitemap to search engines to aid in the discovery and indexing of your site’s content. This is particularly crucial for large sites or sites with deep content archives.

6. Use Breadcrumb Navigation

Implement breadcrumb navigation to enhance not just user experience but also to provide search engines with another layer of information about your site’s structure.

7. Use Noindex Tags When Appropriate

Utilize the “noindex” tag to prevent search engines from indexing pages that do not contribute to your site’s SEO, such as privacy policies or terms and conditions pages.

8. Use Robots.txt to Control Search Engine Crawling

Carefully configure your robots.txt file to ensure critical pages are not inadvertently blocked from search engine crawlers.
