Technical SEO is the backbone of any successful website. It ensures that search engines can crawl, index, and understand your site effectively. However, even experienced website owners and marketers can make technical SEO mistakes that hinder their rankings and user experience. In this blog, we’ll explore the most common technical SEO errors and provide actionable solutions to fix them.
1. Slow Page Speed
The Problem:
Page speed is a critical ranking factor, directly impacts user experience, and is also important for on-page SEO. Slow-loading pages can lead to higher bounce rates and lower search engine rankings.
How to Fix It:
- Optimize Images: Compress images using tools like TinyPNG or ShortPixel without sacrificing quality.
- Enable Browser Caching: Store static resources locally in the user’s browser to reduce load times on subsequent visits.
- Minify CSS, JavaScript, and HTML: Remove unnecessary code and whitespace to reduce file sizes.
- Use a Content Delivery Network (CDN): Distribute your content across multiple servers globally to improve load times for users in different regions.
- Upgrade Your Hosting: Invest in a reliable hosting provider that can handle your site’s traffic and resource demands.
2. Broken Links and Redirects
The Problem:
Broken links (404 errors) and improper redirects frustrate users and waste crawl budget, making it harder for search engines to index your site.
How to Fix It:
- Run Regular Audits: Use tools like Screaming Frog, Ahrefs, or Sitebulb to identify broken links.
- Fix or Remove Broken Links: Update outdated URLs or remove links to non-existent pages.
- Use Proper Redirects: Implement 301 redirects for permanently moved pages and avoid chain redirects (multiple redirects in a row).
- Create a Custom 404 Page: Ensure your 404 page is user-friendly and includes links to popular pages or a search bar.
3. Poor Mobile Optimization
The Problem:
With mobile-first indexing, Google prioritizes the mobile version of your site. A poorly optimized mobile experience can hurt your rankings and drive users away.
How to Fix It:
- Use Responsive Design: Ensure your site adapts seamlessly to different screen sizes.
- Test Mobile Usability: Use Google’s Mobile-Friendly Test tool to identify issues like small text, unplayable content, or clickable elements that are too close together.
- Optimize for Touch: Make buttons and links large enough for easy tapping.
- Avoid Intrusive Pop-Ups: Pop-ups that cover the entire screen can frustrate mobile users and lead to penalties.
4. Duplicate Content Issues
The Problem:
Duplicate content confuses search engines and can dilute your rankings, as they may not know which version to index.
How to Fix It:
- Use Canonical Tags: Specify the preferred version of a page using the rel=”canonical” tag.
- 301 Redirects: Redirect duplicate pages to the original version.
- Consolidate Similar Content: Merge pages with overlapping content into a single, comprehensive resource.
- Avoid Scraped Content: Ensure your content is original and not copied from other sources.
5. Improper Use of Robots.txt
The Problem:
A misconfigured robots.txt file can block search engines from crawling and indexing important pages, effectively making them invisible in search results.
How to Fix It:
- Audit Your Robots.txt File: Use tools like Google Search Console to check for errors.
- Allow Crawling of Key Pages: Ensure critical pages like your homepage, product pages, and blog posts are not blocked.
- Avoid Blocking CSS and JavaScript: Blocking these files can prevent search engines from rendering your site correctly.
- Test Changes: Use the robots.txt testing tool in Google Search Console before implementing changes.
6. Missing or Incorrect XML Sitemap
The Problem:
An XML sitemap helps search engines discover and index your pages. A missing or incorrect sitemap can lead to incomplete indexing.
How to Fix It:
- Generate an XML Sitemap: Use tools like Yoast SEO, Screaming Frog, or online sitemap generators to create an XML sitemap.
- Submit to Search Engines: Submit your sitemap to Google Search Console and Bing Webmaster Tools.
- Keep It Updated: Regularly update your sitemap to include new pages and remove deleted ones.
- Avoid Including No-Index Pages: Ensure pages marked as “no-index” are excluded from your sitemap.
7. Unoptimized URL Structure
The Problem:
Long, complex, or irrelevant URLs can confuse users and search engines, making it harder to understand your content.
How to Fix It:
- Use Descriptive URLs: Include relevant keywords and keep URLs short and clear.
- Avoid Special Characters: Use hyphens (-) to separate words instead of underscores (_) or spaces.
- Stick to Lowercase Letters: URLs are case-sensitive, so using uppercase letters can lead to duplicate content issues.
- Remove Stop Words: Eliminate unnecessary words like “and,” “the,” or “of” to keep URLs concise.
8. Ignoring Structured Data
The Problem:
Structured data (schema markup) helps search engines understand your content better, but many websites fail to implement it correctly or at all.
How to Fix It:
- Add Relevant Schema Markup: Use schema.org to add markup for articles, products, reviews, FAQs, and more.
- Test Your Markup: Use Google’s Rich Results Test to ensure your structured data is error-free.
- Focus on Key Pages: Prioritize adding schema to high-value pages like product pages, blog posts, and contact pages.
9. Crawlability Issues
The Problem:
If search engines can’t crawl your site effectively, they won’t be able to index your content, leading to poor visibility.
How to Fix It:
- Check for Crawl Errors: Use Google Search Console to identify and fix crawl errors.
- Improve Internal Linking: Ensure all important pages are linked internally to help search engines discover them.
- Avoid Infinite Scroll: Use pagination or “load more” buttons instead of infinite scroll, which can confuse crawlers.
- Monitor Crawl Budget: For large sites, ensure low-value pages (like filters or session IDs) are excluded to preserve crawl budget.
10. Ignoring HTTPS
The Problem:
A non-secure (HTTP) site can harm user trust and rankings, as Google prioritizes secure (HTTPS) sites.
How to Fix It:
- Install an SSL Certificate: Contact your hosting provider to install an SSL certificate.
- Update Internal Links: Ensure all internal links point to the HTTPS version of your site.
- Set Up 301 Redirects: Redirect all HTTP pages to their HTTPS equivalents.
- Update External Resources: Ensure all external scripts, images, and resources are loaded over HTTPS.
