When it comes to search visibility, even the best content and backlinks cannot compensate for weak technical foundations. Technical SEO is the backbone that ensures your website is accessible, crawlable, and fast—three key elements that directly influence how search engines rank your site. For businesses in Singapore, overlooking technical SEO can cost valuable opportunities in a highly competitive digital landscape.
In this blog article, we will discuss the most common technical SEO mistakes businesses make, and how to fix them for better rankings.
1. Slow Website Speed
In today’s fast-paced world, users expect websites to load almost instantly. A slow-loading page not only frustrates visitors but also signals poor performance to search engines. Google’s Core Web Vitals make speed and responsiveness even more critical ranking factors.
How to fix it:
- Use tools like Google PageSpeed Insights or GTmetrix to identify bottlenecks.
- Compress images without compromising quality.
- Enable browser caching and use a reliable Content Delivery Network (CDN).
- Consider upgrading your hosting if your current plan can’t handle traffic efficiently.
For many local businesses, optimizing website speed is one of the quickest wins in technical SEO.
2. Poor Mobile Optimization
Singapore has one of the highest smartphone penetration rates in the world. If your website isn’t mobile-friendly, you risk losing both rankings and customers. A common mistake most businesses make is assuming a responsive theme alone guarantees a good mobile experience—yet issues like intrusive pop-ups, tiny fonts, or unclickable buttons still affect many sites.
How to fix it:
- Test your website with a Mobile-Friendly Test tool.
- Simplify navigation for smaller screens.
- Ensure call-to-action buttons are easily tappable.
- Minimize heavy scripts that slow down mobile performance.
Mobile-first indexing means search engines look at your mobile site first—so getting this right is essential for technical SEO optimization.
3. Missing or Incorrect Robots.txt Configuration
The robots.txt file tells search engines which pages to crawl and which to ignore. A single misconfiguration can block important pages from appearing in search results or allow sensitive content to be indexed.
How to fix it:
- Review your robots.txt file to confirm it’s not blocking key pages.
- Disallow only low-value sections (like admin panels or duplicate search results pages).
- Use “noindex” meta tags for pages you don’t want in search results instead of blocking them outright.
This small file plays a significant role in technical SEO audits, so regular checks are highly important.
4. Not Leveraging Structured Data
Structured data (or schema markup) helps search engines understand your content better. Many businesses undermine the significance of it, missing out on rich snippets like star ratings, FAQs, and product details that can enhance click-through rates.
How to fix it:
- Use schema.org vocabulary for key content types (articles, products, events, reviews).
- Test your structured data with Google’s Rich Results Test.
- Update your schema regularly to align with Google’s evolving requirements.
Always remember, adding structured data can give your listings a competitive edge in crowded search results.
5. Ignoring HTTPS Security
Site security is never optional. Google explicitly considers HTTPS as a ranking signal, and users are unlikely to trust a website flagged as “Not Secure.” Yet, some businesses still run on outdated HTTP or have misconfigured SSL certificates.
How to fix it:
- Install an SSL certificate.
- Ensure all HTTP pages redirect properly to HTTPS.
- Fix any mixed-content errors caused by insecure scripts or images.
Migrating to HTTPS is one of the simplest but most effective methods of technical SEO optimizations.
6. Poor Website Structure and Navigation
A disorganized site makes it difficult for both users and search engines to find information. Issues such as broken links, missing sitemaps, or duplicate pages confuse crawlers, lowering your visibility.
How to fix it:
- Create a logical hierarchy with clear categories and subcategories.
- Submit an XML sitemap to Google Search Console.
- Regularly audit for broken links and fix or redirect them.
- Use canonical tags to address duplicate content.
A well-structured site makes technical SEO audits smoother and ensures search engines index your most valuable pages.
7. Skipping Regular Technical SEO Audits
Perhaps the biggest mistake is treating technical SEO as a one-off task. Algorithms, user behaviors, and technologies change constantly, therefore, issues can appear even on previously optimized websites.
How to fix it:
- Conduct a comprehensive technical SEO audit at least once every quarter.
- Use tools like Screaming Frog, Ahrefs, or SEMrush to uncover crawl errors, redirect loops, and duplicate content.
- Keep your CMS, plugins, and scripts updated to avoid security risks.
Ongoing monitoring ensures your site adapts to new SEO standards and stays competitive.
Putting It All Into Practice: Your Technical SEO Action Plan
Here’s a checklist to improve your site’s technical health:
- Run a comprehensive technical SEO audit: You can use tools like Search Console, Screaming Frog, or Ahrefs for this.
- Improve performance: Compress images, minify code, enable caching, and adopt responsive design.
- Clean structure: Resolve broken links, submit XML sitemaps, and solidify internal linking.
- Fix duplicate content: Merge, redirect, or canonicalize overlapping pages.
- Optimize metadata & media: Use unique titles, descriptions, header tags, alt text for each page.
- Streamline URLs and schema: Use clear URLs and add structured data for rich result opportunities.
- Monitor and maintain: Set up analytics, track site health, and conduct routine audits.
