Top 10 WordPress Mistakes Beginners Make in 2025 (and Easy Fixes)
Avoid common WordPress mistakes that can hurt your site’s SEO, speed, and security. Learn what beginners often do wrong—and how to fix it in 2025.
Why This Matters
WordPress is beginner-friendly, but even small mistakes can lead to significant problems, such as slow performance, poor rankings, or even site crashes.
Whether you’re launching a blog or building a business website, avoiding these pitfalls will save time, money, and reputation.
⚠️ Top 10 WordPress Mistakes (and How to Fix Them)
1. ❌ Using “admin” as Username
Hackers love the username “admin.” It’s the first guess in brute-force attacks.
✅ Fix:
Create a unique username and assign admin rights. Delete the default “admin” user after.
2. ❌ Ignoring Permalink Settings
Using the default URL like ?p=123 is bad for SEO and user experience.
✅ Fix:
Go to Settings → Permalinks and choose “Post name” for cleaner, keyword-rich URLs.
3. ❌ Installing Too Many Plugins
Each plugin adds load time and increases the risk of conflicts or vulnerabilities.
✅ Fix:
Use only trusted, essential plugins. Audit and remove inactive plugins regularly.
4. ❌ Not Using an SEO Plugin
Without an SEO plugin, you miss meta titles, descriptions, sitemaps, and schema—all vital for ranking.
✅ Fix:
Install Rank Math or Yoast SEO and configure them properly.
5. ❌ No Image Optimization
Uploading full-size images slows down your site, hurting UX and SEO.
✅ Fix:
Use WebP format and plugins like ShortPixel or Imagify to compress images automatically.
6. ❌ Choosing a Bad Theme
Many free themes are poorly coded, insecure, or slow.
✅ Fix:
Pick a lightweight, SEO-friendly theme like:
-
Astra
-
GeneratePress
-
Kadence
7. ❌ Skipping Mobile Optimization
Google uses mobile-first indexing. If your site doesn’t work on phones, it won’t rank.
✅ Fix:
Test with Google Mobile-Friendly Tool and use responsive themes/plugins.
8. ❌ Not Setting Up Backups
Beginners often skip backups—until their site breaks or is hacked.
✅ Fix:
Use plugins like UpdraftPlus or Jetpack Backup to automate daily backups to Google Drive or Dropbox.
9. ❌ No Caching or Speed Optimization
Slow sites frustrate users and increase bounce rate.
✅ Fix:
Install WP Rocket or LiteSpeed Cache, enable lazy loading, and minify assets.
10. ❌ Forgetting to Secure the Site
Ignoring WordPress security basics makes your site an easy target.
✅ Fix:
-
Use strong passwords + 2FA
-
Install Wordfence or iThemes Security
-
Keep WordPress, themes, and plugins updated
Bonus: Other Mistakes to Watch For
-
Not submitting sitemap to Google Search Console

Forgetting to set a favicon or site icon
