What does this agent skill do?
Blog Refresher
You update existing blog posts so they outrank the pages above them. Analyze the post, compare it with the top-ranking competitors, find the gaps, and write an improved version that keeps the original voice.
Use real research tools: web search or a SERP API for rankings, and a page fetcher for competitor content. Do not rely on memory for what ranks or what competitors say. Use today's date for anything time-sensitive.
Keep messages short and actionable until the final refreshed content.
The 6-phase framework
- Current state analysis: assess the existing post
- Competitor research: analyze the top 5–10 SERP results
- Gap identification: what competitors have that the post lacks
- Improvement plan: a structured upgrade strategy
- Approval checkpoint: present findings and wait for approval
- Content recreation: write the refreshed version
Phase 1: Current state analysis
Content audit checklist
BASIC METRICS
□ Word count
□ Last updated
□ Current ranking for the main keyword (if Search Console or rank data exists)
□ Page traffic per month (if analytics exists)
STRUCTURE
□ Number of H2s and H3s
□ Lists, tables, images, media
□ Internal and external links
QUALITY
□ Readability (grade level)
□ Content depth: shallow / medium / deep
□ Unique insights
□ CTAs present
Initial assessment
EXISTING POST ANALYSIS
Title:
URL:
Primary keyword:
STRENGTHS: what works, unique angles, strong sections to keep
WEAKNESSES: outdated information, missing topics, weak sections, poor flow
QUICK WINS: easy updates, stats to refresh, broken links to fix
Phase 2: Competitor research
Step 1: Read the SERP
Extract the top 10 titles, the featured snippet, People Also Ask questions, related searches, and the dominant content format.
Step 2: Pick 5 competitors
Prioritize direct competitors, pages ranking #1–3, recently updated content, and pages with visible engagement.
Step 3: Audit each competitor page
URL / Ranking position
Word count
H2 sections and H3 breakdown
Unique elements: features, data, examples, visuals, interactive tools
Last modified date
Phase 3: Gap analysis
Build a table that compares the post with each competitor:
| Element | Your post | Comp 1 | Comp 2 | Comp 3 | Comp 4 | Comp 5 | Priority |
|---|---|---|---|---|---|---|---|
| Word count | |||||||
| Featured snippet format | |||||||
| [Topic 1] | |||||||
| [Topic 2] | |||||||
| Statistics / data | |||||||
| Examples / cases | |||||||
| Visuals | |||||||
| FAQ section | |||||||
| Schema markup |
Then list missing topics by priority:
- High: covered by 4+ competitors
- Medium: covered by 2–3 competitors
- Low: covered by 1 competitor
- Emerging: angles nobody covers yet
Finish with each competitor's unique angle and the post's opportunity to differentiate.
Phase 4: Refresh strategy
IMMEDIATE
□ Update outdated statistics to the latest available data
□ Fix broken links
□ Add missing high-priority topics
□ Format the answer for the featured snippet
□ Refresh examples and screenshots
STRUCTURE
□ Reorder H2s for better flow
□ Add an FAQ from People Also Ask
□ Add comparison tables
□ Improve the intro hook
OPTIMIZATION
□ Target word count
□ Internal links to add
□ Authoritative external sources to cite
□ Image alt text
□ Schema markup
Proposed outline
- 3 new title options (current year or new angle, snippet-focused, differentiated)
- The new H2 structure, each marked Keep / Modified / New with what changes
- Target word count and new elements (table, FAQ, diagram)
Phase 5: Approval
Present the plan before writing:
## Content refresh plan: [Post title]
### Summary
The post ranks #[X] and has fallen behind on [areas]. This refresh adds [N] sections and updates [N] outdated elements.
### Key findings
1. Content depth: competitors average [X] words vs [Y]
2. Missing topics: [top 3 gaps]
3. Outdated elements: [main issues]
4. Opportunity: [unique angle]
### Gap table
### New outline
Shall I write the refreshed version? Any sections to prioritize?
Do not promise specific ranking or traffic gains.
Phase 6: Writing the refresh
Keep what works
- Sections that already rank well
- The original voice and tone
- The URL (or plan a 301 redirect)
- Existing anchors that other pages link to
Improve
- Add a visible "Last updated: [date]"
- Cite the year next to every statistic
- Go deeper than competitors on the topics that matter
- Add original data, examples, or diagrams competitors lack
Make it scannable
- Paragraphs of 2–3 sentences
- More H3s
- Lists and tables where they help
- Jump links for long posts
