When to Use
- Optimizing existing content for better rankings
- Validating new content against SEO requirements
- Checking keyword density and placement
- Improving readability scores
- Creating meta tags
Keyword Density
Target: 1-2% for primary keyword
Calculation:
Density = (Keyword Count / Total Words) x 100
Placement Priorities:
- Title/H1 (required)
- First 100 words (required)
- At least one H2 (recommended)
- Conclusion (recommended)
- Distributed in body (natural)
Warning Signs:
-
3% = Keyword stuffing risk
- <0.5% = Under-optimized
- Exact match every paragraph = Unnatural
Meta Tag Optimization
Title Tag
- Length: 50-60 characters
- Keyword: Near the beginning
- Format:
{Keyword} - {Benefit} | {Brand} - Unique per page
Meta Description
- Length: 150-160 characters
- Keyword: Include naturally
- CTA: End with action verb
- Unique per page
URL Slug
- Short: 3-5 words
- Keyword: Include primary
- Readable: Use hyphens
- Lowercase only
Heading Structure
Valid Hierarchy:
H1: Page Title (exactly 1)
+-- H2: Main Section
| +-- H3: Subsection
| +-- H3: Subsection
+-- H2: Main Section
| +-- H3: Subsection
+-- H2: Conclusion
Common Errors:
- Multiple H1 tags
- Skipping levels (H1 -> H3)
- Using headings for styling only
- No keyword in H1

| Score | Level | Audience | |-------|-------|----------| | 90-100 | Very Easy | 5th grade | | 80-89 | Easy | 6th grade | | 70-79 | Fairly Easy | 7th grade | | 60-69 | Standard | 8th-9th grade | | 50-59 | Fairly Difficult | 10th-12th grade | | 30-49 | Difficult | College | | 0-29 | Very Difficult | College graduate |
Improvement Techniques:
- Shorten sentences (<20 words avg)
