1 What is Technical SEO?
Technical SEO refers to the process of optimizing your website’s backend structure to help search engines crawl, index, and rank your content more effectively. It lays the groundwork for your entire SEO strategy—without it, even the best content may never be found.
Unlike on-page SEO (which focuses on content) or off-page SEO (which focuses on backlinks), technical SEO ensures your website is fast, secure, mobile-friendly, and easy for search engines to understand.
Core Components of Technical SEO:
- Site Architecture: Clear structure with logical internal linking and a sitemap.
- Crawlability & Indexing: Make sure search engines can discover and index your pages properly.
- Mobile-Friendliness: Responsive design that works across all devices.
- Page Speed Optimization: Faster load times enhance UX and rankings.
- HTTPS & Security: Secure websites earn more trust from users and search engines.
- URL Structure & Tags: Clean URLs, proper use of header tags, canonical tags, and structured data.
When done right, technical SEO improves not only your visibility in search engines but also the overall user experience. Think of it as making your website search engine ready.
2 Why is Technical SEO Important?
Technical SEO is important because it helps search engines understand and index your website correctly. This is essential for ranking well in SERPs and driving organic traffic to your site.
We’ve listed a few benefits of technical SEO.
- Improved website performance: Technical SEO can help improve your website’s loading speed, a key ranking factor. A faster website is also more user-friendly, which can lead to lower bounce rates and higher conversion rates.
- Increased organic traffic: When your website is technically sound, search engines are more likely to crawl and index it properly. This means your pages are more likely to appear in SERPs for relevant keywords, which can significantly increase organic traffic.
- Better user experience: A technically sound website is also more user-friendly. This means visitors are more likely to stay on your site longer and explore more pages.
- Improved security: Technical SEO can also help to improve your website’s security. By fixing vulnerabilities and implementing security best practices, you can reduce the risk of your website being hacked or compromised.
Overall, technical SEO is an essential part of any SEO strategy. By optimizing the technical aspects of your website, you can improve its performance, visibility, and user experience.
If you’re serious about improving your website’s SEO, investing in technical SEO is important.
3 Best Practices for Technical SEO
We’ll now discuss the best practices you can follow to improve your technical SEO.
3.1 Website Structure
A strong website structure is the foundation of technical SEO. It ensures that search engines can crawl and index your site efficiently, while also providing a smooth navigation experience for users.
URL Structure
Your website’s URL structure plays an important role in SEO. Clean, descriptive URLs help both search engines and users understand what a page is about.

Here are a few of the best practices for SEO-friendly URLs:
- Use relevant keywords (e.g.,
/seo-tips
instead of/page?id=123
) - Avoid unnecessary parameters or special characters
- Keep them short, consistent, and readable
Rank Math makes it easy to review and update URLs in bulk using its built-in CSV method. To do so, navigate to your WordPress dashboard and navigate to Rank Math SEO → Status & Tools → Import & Export.
Under the CSV File section, click on the Export CSV tab. Choose Posts (if you’re editing metadata like SEO Title or Description for blog posts), and click Export, as shown below.

Once the file is downloaded, open it to review the data. Look for URLs that can benefit from optimization—for example, those using underscores instead of hyphens or ones that are too long or unclear.

For instance:
Before: Digital-marketing-strategies-3-5
After: digital-marketing-strategies

Update the necessary fields in the CSV file directly. After making all changes, save the updated file.
Next, go back to the Import tab in the same section of Rank Math and upload the modified CSV file. Rank Math will apply the changes to your website.
Finally, check your site to confirm that the new URLs are live and that any modified URLs have proper redirections in place.
Canonicalization
Canonicalization is a key aspect of technical SEO that helps resolve duplicate content issues by telling search engines which version of a page is the “preferred one”.
Often, the same content can appear under different URL. For instance:
example.com/page
example.com/page?ref=123
www.example.com/page
By using canonical tags, you point search engines to the primary version of a page. This consolidates ranking signals, avoids duplicate content penalties, and ensures accurate indexing.
With Rank Math, setting or changing canonical URLs is very easy.
Navigate to the post or page editor in your WordPress dashboard. Once you’re there, click on the Advanced tab in the Rank Math meta box, where you’ll find the Canonical URL field.
Here, you can add a new canonical URL or edit the existing one to specify the preferred version of your content.

For more information, you can refer to our detailed guide on canonical URLs.
3.2 Indexability and Crawling
In technical SEO, crawling and indexability determine how search engines access and understand your website content.
Crawling is the process by which search engine bots discover pages, while indexability determines whether those pages are added to the search index and can appear in search results.
To manage these processes, one essential tool is the robots.txt
file. This file provides instructions to search engine crawlers about which parts of your site should or should not be crawled.
For instance, you can block specific folders, admin pages, or other low-value content that you don’t want bots to access.
Equally important are meta-directives such as noindex
, nofollow
, and disallow
.
- The
noindex
tag tells search engines not to index a specific page. - The
nofollow
tag instructs bots not to follow certain links, which can help manage link equity. - The
disallow
directive inrobots.txt
restricts crawling access to specific areas of the site, though it doesn’t prevent indexing if a page is linked elsewhere.
Meanwhile, XML sitemaps serve as structured guides for search engines, listing all important URLs and metadata such as last modified dates or update frequency. This is especially helpful for large or dynamic websites, as it ensures that important pages are not missed during crawling.
With Rank Math, you can edit your robots.txt
file directly within the plugin. To do so, navigate to Rank Math SEO → General Settings from your WordPress dashboard. Click Edit robots.txt.

You can also test your file for any errors using our Robots.txt Tester and Validator. Just paste your domain URL, select a crawler, and click TEST. If there’s an issue, it will highlight the error.

Refer to our dedicated tutorial on editing the robots.txt file in Rank Math.
3.3 XML Sitemaps
XML sitemaps play a vital role in technical SEO by helping search engines to efficiently find and index your most important pages. They provide a structured list of key URLs, including details like last modified dates and update frequency, which is especially helpful for large or complex websites.
Creating XML Sitemaps
XML sitemaps serve as crucial navigational guides for search engines, offering a roadmap to the various pages of a website.
With Rank Math, you don’t need to build a sitemap manually. The plugin automatically generates fully compatible XML sitemaps for your website.
You can access and configure them by navigating to Rank Math SEO → Sitemap Settings in your WordPress dashboard. Here, you can customize what content types (posts, pages, custom post types, taxonomies) appear in the sitemap.

This ensures that all important URLs are included and kept up to date as you add new content or update existing pages.
Submitting Sitemaps to Search Engines
Once XML sitemaps are created, the next step in the technical SEO process is submitting them to search engines. This ensures that your content is crawled and indexed more quickly and accurately.
You can submit your sitemap using tools like Google Search Console and Bing Webmaster Tools. The submission typically involved entering your sitemap URL (e.g., https://yourdomain.com/sitemap_index.xml
) into the appropriate field in these tools.

For best results, it’s a good idea to resubmit your sitemap after making major updates to your site structure or adding a large batch of new content.
After your sitemaps are submitted, Rank Math will automatically update any new content you add to your website to the respective sitemaps, and Google will be able to fetch that content seamlessly.
You can further refer to our detailed guide that’ll help you configure sitemaps in Rank Math seamlessly.
3.4 Site Navigation
Site navigation is another important component of technical SEO, influencing how search engines and users navigate and understand a website’s content. Effective site navigation ensures that both search engines and users can easily access and comprehend the structure of a site.
Websites can enhance their technical SEO by implementing a clear hierarchical structure and breadcrumbs, improving search engine rankings and user satisfaction.
Clear Hierarchical Structure
Establishing a clear hierarchical structure is essential for technical SEO. This involves organizing website content logically and hierarchically, clearly distinguishing between main categories and subcategories.
For instance, an e-commerce site might have a top-level category for “Electronics” with subcategories like “Mobiles” and “Cameras.” This hierarchical structure helps search engines comprehend the relationships between different pages, enhancing the site’s overall visibility.

Clear hierarchies also make it easier for users to navigate, improving the user experience.
Breadcrumbs
Breadcrumbs are secondary navigation elements that show a user’s path from the homepage to the current page. They assist users in backtracking easily and provide valuable context to search engines about your site’s structure.
Rank Math SEO plugin simplifies adding the Breadcrumb Schema, a requirement for search engines to display breadcrumbs in search results. For example, here’s how we use breadcrumbs on our page.

With Rank Math, you can easily enable breadcrumbs and automatically generate the required Schema markup. Navigate to Rank Math → General Settings → Breadcrumbs to activate and customize them.

By using clear hierarchies and breadcrumb trails, you make your site more navigable—for both users and search engines—ultimately improving SEO performance.
Refer to our dedicated tutorial on enabling breadcrumbs in Rank Math.
3.5 Use Structured Data
Structured data helps Google comprehend a page’s content more effectively.
By incorporating the appropriate Structured data markup code, your pages have the potential to secure rich snippets. Rich snippets transform search results into more captivating displays, including supplementary information beneath the title and description, as shown below.

Adding Structured data to your posts with Rank Math is as easy as a point-and-click process.
To begin, open the post or page you want to optimize. In the Rank Math meta box, navigate to the Schema tab and click on Schema Generator. From there, you can select the appropriate Schema type, such as Article, Product, FAQ, Recipe, and more, based on the content of your page.

Fill in the required fields in the Schema Builder.

Once completed, simply save or update the post.
If you prefer to automate this, you can set a default Schema type globally. Navigate to Rank Math → Titles & Meta → Posts (or Pages) and select your preferred Schema type from the dropdown.

The selected Schema will then appear in your posts/pages by default.
3.6 Mobile Optimization
Mobile optimization is a pivotal aspect of website development, ensuring an enhanced user experience for visitors accessing a site from mobile devices.
Mobile User Experience
The mobile user experience encompasses navigation, readability, and functionality. A seamless and intuitive mobile experience contributes to higher user satisfaction and engagement.
Elements such as easily tappable buttons, legible fonts, and simplified navigation menus all play a role in creating a positive mobile user experience.
Mobile-Friendly Navigation
Google prioritizes mobile-friendly websites in its rankings, and having a navigation system optimized for smaller screens is imperative.
Responsive design, where the layout adapts to different screen sizes, is a common approach. For example, a mobile-friendly navigation menu might use a collapsible menu to conserve screen space. This meets Google’s mobile-friendliness criteria and enhances the user experience on mobile devices, contributing to improved SEO performance.
Mobile Page Speed
Mobile page speed is a critical factor influencing user experience and search rankings. Mobile users often expect quick loading times, and Google considers page speed in its ranking algorithms on mobiles and desktops.
Optimizing images, leveraging browser caching, and minimizing server requests are common strategies to enhance mobile page speed.
Ensuring swift load times not only pleases users but also aligns with Google’s preferences. Use PageSpeed Insights to check where your website needs to improve.

You can also use Bing’s Mobile Friendliness Test Tool to analyze various factors that affect usability on mobile devices and determine how mobile-friendly the site is.
3.7 Find and Remove Duplicate Content
Duplicate content refers to identical or substantially similar content that appears in more than one place, either on the same website or across different websites.
Duplicate content can arise from various sources, such as:
- URL variations (e.g.,
http://
vs.https://
, trailing slashes) - Printer-friendly versions of pages
- Session IDs and tracking parameters
- Content syndication without proper attribution
- CMS-related issues and eCommerce filters generating multiple URLs for the same content
Content management system (CMS) issues, URL parameters, and e-commerce platforms may inadvertently generate duplicate content.
How to Identify Duplicate Content
To check for potential duplicate content on your site, you can use a simple and effective method:
- Use the “site:” search operator in Google (e.g.,
site:yourdomain.com keyword
) to find all indexed pages related to a specific keyword. If multiple pages are targeting the same keyword with similar content, you may have a duplicate content issue. - Copy and paste a sentence or paragraph from your content into Google search using quotation marks (e.g.,
"exact phrase here"
). This can help identify duplicate content both on your own site and on external sites that may have copied your content.
You can use tools like Semrush’s Site Audit tool to detect duplicate content issues.
Regularly monitoring website analytics and conducting content audits are proactive measures to identify and address duplicate content before it adversely affects SEO performance.
It’s important to note that duplicate content isn’t limited to your own domain. It can also exist across multiple websites. In some cases, this may not be a problem—especially if the content is syndicated intentionally through partnerships or content distribution networks. However, without proper canonical tags or attribution, search engines might not know which version to prioritize, which can hurt your SEO.
If you syndicate content, always ensure you:
- Use canonical tags pointing to the original source
- Have clear agreements with the republishing sites
- Provide unique context or summaries where possible to avoid confusion with duplicate content
Strategies to Handle Duplicate Content
Addressing duplicate content requires strategic implementation:
- Canonicalization: As explained before, use canonical tags to specify the preferred version of a page when duplicate content exists. This informs search engines about the primary source and consolidates ranking signals.
- 301 Redirects: Implementing 301 redirects from duplicate URLs to the canonical version helps consolidate link equity and ensures that users and search engines are directed to the correct page.
- Parameter Handling: Configure URL parameters in Google Search Console to guide search engines on how to treat variations. This is particularly relevant for e-commerce sites with filtering options.
- Content Syndication Best Practices: If syndicating content, use rel=”canonical” tags to prevent duplicate content issues. Ensure that syndicated content adds value and includes proper attribution.
- Consistent Internal Linking: Maintain a consistent internal linking structure to avoid unintentional creation of duplicate content through multiple pathways.
3.8 Page Speed Optimization
Page speed significantly influences user experience.
According to our Future of Search Report, 98% of respondents say website performance is important, with 45% citing better rankings, 24% lower bounce rates, and 21% more conversions as the key benefits of faster-loading sites.

Compress images without compromising quality using tools like TinyPNG or ImageOptim.
Minify CSS and JavaScript files by removing unnecessary spaces, line breaks, and comments. Enable browser caching to store static resources locally on a user’s device.
Set appropriate expiration headers for cached resources to ensure users receive the latest content when necessary.
You can use the best caching plugin, like WP-Rocket, to speed up your website’s pages and result in faster load times.
Refer to our dedicated tutorial on Page Speed Optimization to deliver exceptional performance to your audience.
3.9 Ensure Website Security
Prioritizing website security in technical SEO is necessary for user trust and search engine rankings.
SSL Certificates and HTTPS
SSL (Secure Socket Layer) certificates are fundamental for website security. They encrypt the data between a user’s browser and the website’s server, preventing unauthorized access. An SSL certificate is crucial for security and positively influences search engine rankings.
Implementing HTTPS (Hypertext Transfer Protocol Secure) ensures a secure and encrypted connection.
Protection Against Malware and Hacking
Utilize firewalls and security plugins to fortify your website against hacking attempts and malware. These tools actively monitor and filter out malicious traffic, enhancing overall security.
Conduct regular security audits to identify vulnerabilities. Addressing potential weaknesses promptly helps prevent unauthorized access and protects sensitive data.
Regular Backups
Regularly back up your website’s data and files. This ensures that you can quickly restore your site to a previous, secure state in case of a security breach or data loss.
Store backups in secure, off-site locations to safeguard against server failures or other disasters that could compromise your primary data storage.
Refer to our dedicated tutorial on backing up WordPress websites.
Data Privacy and GDPR Compliance
Prioritize the protection of user data. Ensure that sensitive information is encrypted and stored securely, adhering to best practices for data privacy.
Comply with the General Data Protection Regulation (GDPR) standards, especially if your website collects or processes data from users in the European Union. This involves obtaining explicit consent for data collection and implementing measures to secure and manage user data responsibly.
