What it does

SEO Optimizer is an agent skill from OneWave-AI/claude-skills. Optimize content for search engines with keyword analysis, readability scoring, meta descriptions, and competitor comparison. Use this when users want to improve SEO, optimize blog posts, or analyze content for search performance.

Its SKILL.md is about 1.7k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Writing & Content, covering On-page SEO, Plain language and style rules and Blog and article writing. The repository describes itself as: 200+ production-ready Claude Code skills for sales, marketing, design, engineering, and AI agent architecture. Built and maintained by OneWave AI. The licence is MIT.

When your agent uses it

  • S want to improve SEO
  • Optimize blog posts
  • Analyze content for search performance

Example prompts

  • “/seo-optimizer”

Workflow steps

6 steps, taken from the step headings in SKILL.md.

  1. Analyze Target Keywords
  2. Evaluate Content Structure
  3. Readability Analysis
  4. Technical SEO Elements
  5. Content Quality Assessment
  6. Provide Actionable Recommendations

What it can do on your machine

Read from SKILL.md and the folder at commit fc5b785. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are markdown).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

SEO Optimizer loads about 1.7k tokens when it runs. Until then it costs about 61 tokens; SKILL.md has 374 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~61
When it runs · the whole SKILL.md, loaded when a task matches
~1.7k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SEO Content Optimizer

Comprehensive SEO analysis and optimization for content creators and marketers.

To optimize content for SEO, provide a detailed analysis covering keywords, readability, technical SEO, and actionable recommendations.

Instructions

1. Analyze Target Keywords

Examine keyword usage and placement:

  • Identify primary keyword(s) from user input or content
  • Check keyword placement (title, H1, first 100 words, subheadings)
  • Calculate keyword density (aim for 1-2%)
  • Identify LSI keywords and semantic variations present
  • Flag keyword stuffing issues
2. Evaluate Content Structure

Assess the organization and hierarchy:

  • Check heading hierarchy (single H1, then multiple H2, then H3)
  • Verify keyword usage in headings
  • Evaluate heading descriptiveness
  • Check paragraph length (aim for <150 words)
  • Assess overall scanability
3. Readability Analysis

Calculate readability metrics:

  • Flesch Reading Ease score (aim for 60-70)
  • Grade level estimation
  • Average sentence length (aim for <20 words)
  • Passive voice percentage (minimize)
  • Transition word usage
  • Paragraph structure
4. Technical SEO Elements

Generate optimized meta elements:

  • Meta Title: 50-60 characters with primary keyword
  • Meta Description: 150-160 characters, compelling with keyword
  • URL Slug: Short, keyword-rich, hyphen-separated
  • Image Alt Text: Descriptive with keywords where natural
  • Internal Linking: Opportunities to link to related content
  • External Links: Quality of outbound links
5. Content Quality Assessment

Evaluate comprehensiveness:

  • Word count (competitive topics need 1500+ words)
  • Content depth and detail level
  • Topic coverage completeness
  • Unique value proposition
  • E-A-T signals (expertise, authority, trust)
  • Content freshness (dates, current examples)
Show full SKILL.md (148 more words)Show less
6. Provide Actionable Recommendations

Prioritize improvements by impact:

Critical (Fix Immediately):

  • Missing or poor meta description
  • No keyword in title or H1
  • Broken internal links
  • Keyword density too high/low

High Priority:

  • Poor readability score
  • Weak heading structure
  • Missing alt text on images
  • Content too thin

Medium Priority:

  • Could add related keywords
  • Opportunity for featured snippet
  • Could improve internal linking

Provide specific, actionable fixes with examples.

## Best Practices

- **Prioritize user experience** over keyword stuffing
- **Write for humans first**, optimize for search engines second
- **Provide specific examples**, not vague advice
- **Consider search intent** behind keywords (informational, commercial, transactional)
- **Recommend content additions**, not just optimization
- **Check for E-A-T signals** (author bio, credentials, sources)
- **Suggest schema markup** where relevant (FAQ, How-To, Review)
- **Look for featured snippet opportunities** (definition boxes, lists, tables)

## Example Workflow

**User request**: "Optimize this blog post for 'best project management tools'"

**Analysis**:
1. Check keyword placement - found in title but not H1 (fix needed)
2. Calculate density - 0.5% (too low, needs 8-10 more mentions)
3. Analyze readability - Flesch score 55 (good), but sentences too long
4. Generate meta tags - create compelling meta description
5. Identify gaps - missing "pricing comparison" and "team size recommendations"
6. Find internal links - link to "project management tips" article
7. Suggest featured snippet - format comparison table
8. Provide prioritized action list

---

**Remember**: SEO is about creating valuable, well-optimized content that serves user intent better than competitors.
