If your Rank Math SEO panel is showing red errors under “Additional” or your SEO score is low, don’t worry. Most Rank Math issues can be fixed by optimizing your focus keyword, title, meta description, content length, internal links, and image ALT tags.
In this guide, you’ll learn how to fix Rank Math SEO errors step-by-step and improve your SEO score to 80+ easily.
How to Fix Rank Math SEO Errors: Understanding Rank Math SEO Panel

When you edit a post, Rank Math shows:
- ✅ Basic SEO
- ❌ Additional (Errors)
- ✅ Title Readability
- ✅ Content Readability
If “Additional” shows errors, it usually means:
- Focus keyword missing
- Keyword density low
- No internal links
- No external links
- Images missing ALT text
- Content too short
Let’s fix them one by one.
Step 1: Add Focus Keyword Properly
Go to Rank Math section and add your primary keyword.
Make sure your focus keyword appears in:
✔ SEO Title
✔ Meta Description
✔ First 100 words
✔ At least one subheading
✔ URL slug
Example:
If your keyword is:
WordPress login page 404 error
Your title should look like:
“WordPress Login Page 404 Error – Step-by-Step Fix Guide”
This alone increases Basic SEO score.
Step 2: Fix Additional Errors in Rank Math
If “Additional” shows red error like in your screenshot:

Keyword Density Low
Add keyword naturally 4–6 times (for 1000-word article).
Don’t stuff.
No Internal Links
Add at least 1–2 internal links.
Example:
Link to your previous WordPress troubleshooting article.
No External Links
Add one authority external link (example: wordpress.org).
Image ALT Missing
Edit your image → Add ALT text using focus keyword.
Example ALT:
“WordPress login page 404 error fix screenshot”
Content Too Short
Rank Math prefers 600+ words.
For better ranking, target 900–1200 words.
Step 3: Improve Title Readability
Rank Math checks:
- Power words
- Numbers
- Emotional words
- Sentiment
Instead of:
“Fix WordPress Error”
Write:
“WordPress Login Page 404 Error – Easy Step-by-Step Fix Guide”
Better CTR = Better ranking.
Step 4: Improve Content Readability
Rank Math looks for:
✔ Short paragraphs
✔ Subheadings
✔ Bullet points
✔ Images
✔ Transition words
Avoid large blocks of text.
Good example:
- Use H2 every 200–300 words
- Use bullet lists
- Keep paragraphs 2–3 lines
