When it comes to improving our website’s visibility, technical SEO plays a crucial role. Even the most compelling content and stunning design won’t matter if search engines can’t properly crawl and index our site. Unfortunately, technical SEO errors are more common than we think, and they can quietly undermine our rankings.
The good news is that most of these issues are fixable with the right approach. From broken links to slow-loading pages, tackling these problems not only boosts our search performance but also enhances user experience. Let’s dive into the most common technical SEO errors and how we can resolve them to keep our site in top shape.
Understanding Technical SEO
Technical SEO focuses on optimising the backend aspects of a website to support crawling, indexing, and ranking processes. Search engines use algorithms to evaluate factors like website structure, performance, and accessibility, making technical elements critical for visibility.
We prioritise fixing technical barriers, as no content ranks effectively if search engines encounter issues during crawling. For example, improper URL structures or absent XML sitemaps diminish a site’s discoverability. Addressing these gaps ensures search engines can interpret and rank pages correctly.
Technical SEO also affects user experience. Fast-loading pages, secure HTTPS protocols, and mobile-friendly designs not only boost rankings but also meet visitor expectations. A well-optimised site balances technical accuracy with seamless usability.
Common Technical SEO Errors To Watch For
Technical SEO errors can block search engines from fully understanding or indexing a site, leading to poor rankings. We’ve identified the key issues to monitor and fix for optimal performance.
Crawlability Issues
Crawlability issues occur when search engine bots struggle to access website pages. These problems often arise from incorrect robots.txt configurations, blocked URLs, or missing internal links. For instance, disallowing critical pages in the robots.txt file prevents indexing. Regular crawling diagnostics identify these errors promptly.
Duplicate Content
Duplicate content confuses search engines, making it difficult to determine which page to rank. Common causes include HTTP/HTTPS or www and non-www URL variations, duplicate meta descriptions, and pagination. Using canonical tags, setting preferred domain versions, and consolidating duplicate URLs solve these problems efficiently.
Slow Page Load Speeds
Pages that load slowly, especially those exceeding a three-second threshold, degrade user experience and hurt rankings. Factors include unoptimised images, excessive JavaScript, and bulky CSS. Tools like Google PageSpeed Insights help pinpoint issues. Compressing files and leveraging browser caching improves load times significantly.
Broken Links
Broken links lead to 404 errors, signalling poor site maintenance and frustrating visitors. These links often result from deleted, moved, or misspelled pages. Regularly using a broken link checker ensures quick detection. Redirecting broken URLs or updating internal links restores functionality and maintains link equity.
Mobile-Friendliness Problems
Non-responsive designs or incompatible features harm mobile usability. Google prioritises mobile-first indexing, making mobile optimisation essential. Issues include non-scalable elements and horizontal scrolling. Responsive design frameworks and testing with Google’s Mobile-Friendly Test help resolve these concerns.

Best Practices For Fixing Technical SEO Errors
Implementing best practices is essential for resolving common technical SEO issues that can harm a site’s search rankings. These strategies improve site performance, user experience, and overall visibility.
Improving Site Crawlability
Ensuring search engines can crawl our site is fundamental. We should review the robots.txt file for unintended disallowed pages and verify that critical pages aren’t blocked. XML sitemaps, submitted through Google Search Console, help search engines efficiently locate and index content. If crawl errors appear in Search Console, resolving issues like server errors or DNS failures is critical to maintaining accessibility.
Addressing Duplicate Content
Managing duplicate content is crucial to avoid indexing problems and ranking penalties. Implementing canonical tags on duplicate pages ensures search engines know the preferred URL to index. We should consolidate variations, such as HTTP vs HTTPS or www vs non-www, with 301 redirects. Regularly auditing meta elements prevents duplication in title tags and descriptions.
Enhancing Page Speed
Page speed optimisations directly affect rankings and user satisfaction. Compressing large files using tools like GZIP reduces load times, while optimising images with formats like WebP ensures quicker rendering. Leveraging browser caching allows returning visitors to load resources faster. Using PageSpeed Insights or GTmetrix identifies specific slowdowns, guiding adjustments.
Fixing Broken Links
Broken links disrupt navigation and harm SEO. Using tools like Screaming Frog or Ahrefs, we can scan for 404 errors and other link issues. Replacing or redirecting these links to relevant pages ensures usability. Setting up a custom 404 page provides a fallback that enhances user experience even when errors occur.
Optimising For Mobile Devices
Mobile optimisation is critical due to Google’s mobile-first indexing. Implementing responsive design ensures our website adapts seamlessly to various screen sizes. Tools like Google’s Mobile-Friendly Test identify mobile usability issues. Additionally, prioritising fast load speeds for mobile pages enhances both SEO and user engagement.
Conclusion
Fixing technical SEO errors is a crucial step towards achieving better rankings and providing a seamless experience for users. By addressing issues like crawlability, duplicate content, and page speed, we can ensure our site is both search engine-friendly and user-focused.
With the right tools and consistent monitoring, it’s entirely possible to maintain a well-optimised website that performs at its best. A proactive approach to technical SEO not only boosts visibility but also builds a solid foundation for long-term success. Let’s prioritise these efforts to stay ahead in an ever-evolving digital landscape.
