10 SEO Mistakes That Kill Your Ranking On Google And How To Avoid Them.
1. Ignoring Mobile Optimization 📱
Why is this a problem?
Google favors mobile-friendly sites thanks to its “Mobile-First” indexing. A site that is not optimized for mobile leads to a bad user experience, a high bounce rate, and a low ranking on Google.
How to avoid it?
- Use a responsive design: make sure your site adapts to different screen sizes.
- Test your site on Google Mobile-Friendly Test: Google Mobile-Friendly Test
- Improve mobile speed: minimize image weight and enable lazy loading.
2. Loading Time Too Long ⏳
Why is this a problem?
Slow sites impact user experience and conversion rate. Google considers loading speed as a major SEO factor with the Core Web Vitals.
How to avoid it?
- Optimize images using formats like WebP.
- Enable caching (with plugins like WP Rocket on WordPress).
- Minify CSS and JavaScript to reduce loading time.
- Use efficient hosting and a CDN (Content Delivery Network).
3. Neglecting Content Quality ✍️
Why is this a problem?
Google favors relevant, useful, and well-structured content. Content that is too short, duplicated, or uninformative can harm your SEO.
6. Don’t Optimize Your Images 🖼
Why is this a problem?
Heavy images slow down the site and without alt tags, they are not understood by Google.
How to avoid it?
- Compress images without losing quality (TinyPNG, Imagify).
- Correctly name your files (example:
seo-error-common.jpginstead ofIMG123.jpg). - Add a descriptive ALT tag for accessibility and SEO.
7. Not Tracking and Analyzing Your SEO 📊
Why is this a problem?
Not tracking your SEO prevents you from identifying opportunities for improvement.
How to avoid it?
- Use Google Search Console to track indexing and errors.
- Install Google Analytics to analyze traffic and user behavior.
- Track keyword positions with tools like SEMrush, Ahrefs, or Ubersuggest.
8. Poor Backlink Management 🚨
Why is this a problem?
Backlinks are a key factor in SEO. However, toxic or artificial links can lead to a Google penalty (Penguin).
How to avoid it?
- Obtain natural backlinks via partnerships or quality content.
- Avoid link purchases or dubious exchanges.
- Use Google’s “Disavow Links” tool in case of toxic links.
9. Not Adapting Your SEO to Search Intentions 🎯
Why is this a problem?
If your content does not match users’ expectations, Google will consider it less relevant.
How to avoid it?
- Analyze search intent: informative, transactional or navigational.
- Create content that meets the needs of users.
- Use various formats: text, video, infographics.
10. Ignoring Site Security 🔒
Why is this a problem?
Google penalizes unsecured sites (without HTTPS). A hacked or vulnerable site can be deindexed.
How to avoid it?
- Install an SSL certificate (HTTPS) to secure connections.
- Update your CMS and plugins to avoid security breaches.
- Use a firewall and monitor attacks with a tool like Wordfence.
