Complete Technical SEO Checklist to Optimize Your Website

Improving your website’s overall SEO score means working on the technical side, so I’ve created this complete technical SEO checklist to help you.

Remember, while a major part of your SEO strategy will be focused on high-quality content creation, distribution, and acquiring strong backlinks, it’s not just about that.

Technical SEO still remains the foundation that helps search engines crawl, index, and rank your site.

So, in this blog, I’ll share the ultimate technical SEO checklist with practical tips that you can use to boost your site’s performance and visibility.

Let’s start by understanding what technical SEO is.

What is Technical SEO?

Technical SEO optimizes a website’s technical aspects to ensure search engines can crawl, index, and rank content effectively.

This includes improving site speed, mobile-friendliness, security (HTTPS), and creating an organized URL structure.

By focusing on these elements, technical SEO ensures that search engines can easily access and understand the website’s content, boosting its visibility in search results.

Remember, even the best content may struggle to rank without proper technical SEO.

While on-page SEO encompasses content creation and off-page SEO focuses on link building, technical SEO ensures a solid foundation for the site architecture.

How Does a Technical SEO Checklist Help Optimize Your Website?

Using a technical SEO checklist is like conducting a health check-up for your website.

It helps uncover site issues and gives you a roadmap to fix them, ensuring that your website is easy for search engines to crawl and index.

Following a technical SEO checklist improves your site’s search engine rankings and enhances the user experience.

Now that you understand technical SEO better, let’s examine the checklist for conducting it.

Website Structure Checklist

1. Check URL Structure

A clean, well-optimized URL structure enhances user experience and search engine understanding, contributing to higher search rankings and improved site accessibility.

This is because search engines rely on URLs to understand the hierarchy and relevance of your web pages.

So, well-structured URLs make it easier for search bots to crawl your site and index its content correctly.

To optimize URL structure, do the following:

• Keep the URL short to accurately reflect the page’s content and include the focus keyword.
• Avoid overly long URLs that can dilute keyword relevance.
• Use hyphens, not underscores, because search engines treat hyphens as spaces, improving readability.
• Keep URLs simple and clean by removing session IDs or tracking codes unless essential.
• Ensure consistency in naming conventions across your site to improve internal linking and user navigation.

So, for clarity and SEO impact, instead of `mywebsite.com/complete-technical-SEO-checklist-for-2024`, you should use `mywebsite.com/technical-seo-checklist.`

You can also use AIOSEO’s TruSEO feature to optimize your URLs while creating WordPress drafts for your blogs and web pages.

It provides recommendations on improving the page’s overall on-page SEO score, including creating an optimized URL structure.

2. Check Navigation

A clear primary navigation is essential for user experience and search engine optimization.

To achieve this, you should create a logical navigation system that efficiently guides users through the site while allowing search engines to crawl and understand the website’s structure.

Here’s how you can optimize site navigation:

• Ensure clear, primary navigation so that every main section is easily accessible from the homepage, allowing users to find the information they need without confusion quickly.
• Incorporate breadcrumb navigation to provide a secondary navigation system. This system shows users the path to a particular page, enhancing usability and SEO.
• Link internally to related content to ensure that search engines can crawl the website effectively while encouraging users to explore more content, boosting engagement.

3. Check Internal and External Links

Properly managed links are essential for SEO success, as they contribute to a website’s authority, user experience, and search engine visibility.

Here’s how you can optimize this process:

• Fix broken links using tools like AIOSEO’s Broken Link Checker to locate and fix broken internal or external links to prevent any negative impact on user experience and SEO.
• Use internal linking to link to related articles and pages to help search engines discover more content.
• Regularly review backlinks to ensure that low-quality or spammy sites aren’t dragging down your site’s authority.

You can also use AIOSEO’s Link Assistant feature, which streamlines adding and managing internal links, making linking-related content easy and boosting SEO performance.

4. XML Sitemaps and Robots.txt Optimization

Both XML sitemaps and robots.txt are essential tools for guiding search engines on how to interact with your site.

They help search engines understand which parts to crawl and which to prioritize.

Here’s how you can optimize it:

• Submit updated sitemaps to search engines. 
• Ensure your XML sitemap is up-to-date, includes all relevant pages, and is submitted through Google Search Console and Bing Webmaster Tools for improved crawlability.
• Monitor the robots.txt files to ensure they do not block important pages from being crawled by search engines, ensuring maximum visibility for the right content.

5. Handle Redirects (301, 302)

Redirects are critical in ensuring a seamless user experience and preserving your site’s SEO value when moving content or updating URLs.

Here’s how you can manage redirects:

• Use 301 redirects for permanent moves to ensure that the SEO value from the old URL is passed on to the new one.
• Only use 302 for temporary changes or when content is temporarily unavailable or being updated.

6. Manage Pagination and Infinite Scroll

Managing pagination and infinite scroll ensures that search engines can properly crawl and index your content.

Here’s what you should do:

• Use rel=”next” and rel=”prev” tags. These tags help search engines understand the relationship between paginated pages and improve content crawlability across multiple pages.
• For sites using infinite scroll, always provide users (and search engines) with a “View All” button to ensure all content is discoverable and can be indexed.
• Implement canonical tags to prevent duplicate content issues by signaling to search engines which version of paginated or infinitely scrolling content should be indexed as the main version.

Crawlability and Indexability Checklist

7. Ensure Accessibility for Search Engine Crawlers

If search engines can’t crawl your site efficiently, important content might not appear in search results, impacting your visibility and traffic.

This is why, ensuring that search engines can crawl your site is crucial for indexing and ranking.

Here’s how you can do that:

• Review the robots.txt files to ensure that key pages like blog pages aren’t accidentally blocked, as that can prevent them from being indexed and showing up in search results.
• Monitor crawl errors in Google Search Console, such as “blocked by robots.txt” or other crawling issues.

8. Handle JavaScript Rendering and AJAX

JavaScript-heavy websites can present challenges for search engines, as they often rely on client-side rendering, making it difficult for crawlers to index content properly.

Without proper optimization, search engines may struggle to index key content on your site, negatively impacting your SEO performance and rankings.

Here’s what you can do to handle JavaScript rendering:

• Use server-side rendering (SSR) to ensure that important content is visible to search engines, even if users rely on JavaScript.
• Test with Google Search Console’s ‘Fetch and Render’ to identify any issues with how JavaScript content is displayed and indexed.

9. Optimize Site Speed

Site speed is perhaps one of the most important factors in optimizing your website.

That’s because it impacts both user experience and search engine rankings. 

A slow-loading website not only frustrates visitors but also impacts your SEO, as search engines favor fast sites.

Faster websites lead to higher user engagement and lower bounce rates, both of which are critical factors in search engine ranking algorithms.

So, here’s what you can do to optimize your site speed:

• Use speed testing tools like Google PageSpeed Insights to assess the areas for improvement.
• Compress images and minify code to ensure that your site loads faster, providing a smoother user experience and helping to boost rankings.

10. Check Canonicalization and URL Parameters

Canonicalization and URL parameters are essential for avoiding duplicate content issues, which can confuse search engines and dilute your ranking potential.

By properly managing these elements, you ensure that search engines focus on your preferred content.

Here’s how to do that:

• Use canonical tags correctly to signal search engines which version is the main one.
• Manage URL parameters properly to filter or track codes.

Mobile Optimization Checklist

11. Responsive Design and Mobile-Friendly Testing

With Google’s mobile-first indexing, mobile friendliness has become of paramount importance.

This means Google predominantly uses the mobile version of a site for indexing and ranking.

So, ensuring your site is optimized for mobile devices is essential for maintaining visibility in search results.

Here’s how you can do that:

• Implement mobile-responsive web design to ensure that your website automatically adjusts to different screen sizes.
• Test using Mobile-Friendly Test.

12. Mobile Site Speed and Performance Optimization

As discussed above, mobile site speed is critical in user experience, especially since mobile users expect fast-loading pages. 

A slow mobile site can lead to higher bounce rates and negatively impact search rankings and we don’t want that.

So, here’s how to optimize mobile performance for better results:

• Compress images and minify CSS, JavaScript, and HTML to ensure that mobile pages load quickly. 
• Regularly test mobile speed with tools like Google PageSpeed Insights to identify and address any performance bottlenecks.
• Implement Accelerated Mobile Pages (AMP) by stripping down unnecessary elements to significantly enhance mobile loading times. This will lead to faster load times and improved user experience.

Website Security Checklist

13. Check the HTTPS Status

A secure website using HTTPS signals to the users that it’s safe to browse the website without compromising the safety of their data or any online viruses.

It is important for both user trust and SEO performance. 

This is why, Google prioritizes secure websites in rankings, and users feel safer browsing a fully encrypted site.

So, here’s how to check for your website’s HTTPS status:

• Migrate from HTTP to HTTPS to ensure all communication between the user’s browser and your website is encrypted, safeguarding sensitive data.
• After migrating, ensure that all site resources, such as images, scripts, and stylesheets, are also served over HTTPS to prevent browser warnings and avoid hurting the user experience.

14. Implement SSL Certificates

Talking about your website’s security, SSL certificates are the way to go.

They are important for creating a secure, encrypted connection between your website and its users.

This not only protects sensitive information but also improves your SEO performance, as search engines prioritize secure sites.

Here’s how to implement it:

• Obtain and install an SSL certificate from a reputable Certificate Authority (CA) and ensure it’s properly installed on your web server.
• Regularly renew SSL certificates to avoid lapses in security, which could result in browser warnings and reduced search engine rankings.

Schema Markup Technical SEO Checklist

15. Implementing Schema Markup for Rich Snippets

Schema markup is important for optimizing search engines’ understanding and display of your content.

By adding structured data, you enable rich snippets and enhanced search result listings that stand out and provide more information at a glance, improving click-through rates and engagement.

You can use AIOSEO to implement schema markup automatically.

AIOSEO simplifies the process of adding schema markup to your site without needing to touch any code.

Here’s how you can configure schema settings in AIOSEO after you’ve installed it:

• Enable schema markup and, depending on your content, choose from various schema types, such as articles, FAQs, or local businesses.
• You can also customize schema settings to ensure accuracy and relevance.
• Validate with the built-in testing tool to ensure everything functions correctly.

Site Speed and Performance Checklist

16. Minification and Compression of CSS, JavaScript, and HTML

Improving site speed is important for both user experience and search rankings. 

This is where minifying and compressing your site’s code can help ensure faster load times by reducing file sizes, making your website more efficient.

To do that, minify all code and reduce the size of CSS, JavaScript, and HTML files by removing unnecessary characters, spaces, and comments.

17. Optimize Image and Multimedia Content

Images and multimedia are important to your website’s visual appeal but can significantly slow down load times if not optimized. 

Ensuring fast multimedia load times enhances both user experience and search engine performance.

So, here’s how to do that:

• Compress all images without losing quality. This cuts down the time it takes for a browser to load your site while maintaining the visual quality of your images.
• Instead of loading unnecessarily large images, ensure the site delivers appropriately sized images based on the user’s device.

To streamline the image optimization process, use SEOBoost’s content management feature.

The content management feature allows you to store, organize, and easily access all your images from its media library. 

It ensures that you can quickly find and reuse optimized assets across different pages or campaigns.

SEOBoost’s library also allows you to find stock images, saving time when sourcing visuals while maintaining high performance through optimization.

18. Leverage Browser Caching and Content Delivery Networks (CDNs)

Using browser caching and a CDN (Content Delivery Network) are important strategies for boosting your site’s speed and performance, especially for global audiences.

Here’s how to do it:

• Configure browser caching to store static resources like CSS files, JavaScript, and images in a visitor’s browser. This way, when they revisit the site, the browser doesn’t have to reload these elements, reducing page load times.
• Use a CDN to distribute your website’s static files (e.g., images, CSS, JavaScript) across a network of servers worldwide.
