Po co content audit?

Problem stron z 100+ artykułami

Po 2-3 latach publikowania:

• 50% artykułów ranks pos 50+ (niezauważalne)
• 20% artykułów outdated (stats, links, info)
• 10% artykułów off-topic (poza klastrem authority)
• Zostaje 20% pulling all the weight

Topical authority spada gdy:

• Domena zawiera dużo low-quality contentu
• Internal linking dropping autorytet na słabe pages
• Crawl budget marnowany na pages, których Google nie indeksuje

Audit benefit

• +30-50% organic traffic bez nowego contentu (Backlinko study)
• Lepsza freshness signal dla updated pages
• Boost top performers through internal linking restructure
• Topical authority clean up — fewer but stronger pages

Framework: 5 actions

LEAVE (zostawić)

Kryteria:

• Top 10 ranking dla target query
• Stable position (no decline 6 mies.)
• Decent CTR (3%+ for top 10)
• Fresh content (updated within 12 mies.)
• Strong internal links to it

Action: None. Monitor. Refresh w roku przyszłym.

UPDATE (zaktualizować)

Kryteria:

• Pos 5-30 (potential dla top 10)
• Ranking declining ale not crashed
• Content factually correct ale outdated stats/examples
• 1500+ słów (good base, just needs refresh)

Update tactics:

• Update stats z fresh data (2026)
• Add new sections (recent developments)
• Refresh examples (replace 2022 case studies with 2025-26)
• Update screenshots, links
• Expand FAQ section
• Bump updatedDate w schema

Time investment: 30-90 min per page.

REWRITE (przepisać)

Kryteria:

• Pos 30-100 (struggling)
• Thin content (<800 słów)
• Outdated approach lub wrong angle
• Decent topic but poor execution

Rewrite approach:

• Keep URL (don't change)
• Keep core topic (don't shift)
• New comprehensive content (1500-3000 słów)
• New structure (better H2/H3)
• New examples, data, perspective
• Schema enhancements

Time investment: 3-6h per article.

MERGE (połączyć)

Kryteria:

• 2-3 artykuły na bardzo podobny topic
• Each ranking pos 30-80
• Cannibalizing each other (split authority)

Merge process:

1. Identify primary URL (highest ranking)
2. Combine best content from all
3. Improve to comprehensive guide
4. 301 redirect inne URL-e → primary
5. Update internal links
6. Submit nowy URL w GSC

Time investment: 4-8h per merge.

DELETE (usunąć)

Kryteria:

• 0-5 visits/mies. for 12+ miesięcy
• No backlinks
• Off-topic dla current strategy
• Unfixable (e.g. obsolete product/topic)

Delete process:

1. 301 redirect to most relevant remaining page (zachowuje link equity)
2. NOT just delete — to leaves 404
3. Update internal links w innych artykułach
4. Submit URL removal w GSC

Time investment: 15 min per delete.

Step-by-step audit process

Step 1: Inventory (week 1)

• Crawl strony Screaming Frog (lista wszystkich URL-i)
• Export GSC Performance (impressions, clicks, position per URL)
• Export Ahrefs/Semrush (rankings per URL)
• Export GA4 (sessions per URL)

Compile w jeden spreadsheet:

URL	Title	Imp	Clicks	Avg Pos	GA4 sessions	Backlinks	Updated date

Step 2: Categorization (week 2)

Per page, decide LEAVE / UPDATE / REWRITE / MERGE / DELETE.

Quick rules:

• Imp >1000 + Pos <10 → LEAVE
• Imp >500 + Pos 10-30 → UPDATE
• Imp >100 + Pos 30-100 + content >800 słów → UPDATE
• Imp >100 + Pos 30-100 + content <800 słów → REWRITE
• 2+ URL-e na same topic + each ranks pos 30+ → MERGE candidates
• Imp <20 + 12 mies. old + no backlinks → DELETE

Step 3: Prioritization (week 2)

Sort by potential ROI:

• High potential: Already in top 30 + good imp + needs minor update
• Medium: Pos 30-100 + decent imp + needs rewrite
• Low: Already top 10 (just monitor) lub delete candidates

Start z high potential — biggest ROI per hour.

Step 4: Execution (week 3-12)

Plan: ~5-15 actions per week (sustainable pace).

Sample 12-week plan dla 200-page site:

• Week 1-4: Update 20 high-potential pages
• Week 5-8: Rewrite 10 thin content pages
• Week 9-10: Merge 5 cannibalizations
• Week 11-12: Delete 30 dead pages

Total: 65 actions affecting ~33% of site.

Step 5: Monitoring (week 13+)

Track post-audit:

• GSC Performance trends — typowo wzrost po 4-12 weeks
• Specific page rankings (Ahrefs Rank Tracker)
• Crawl budget — Google should crawl more efficiently
• Internal links — verify no broken after merges/deletes

Najczęstsze błędy w content audit

1. Audit raz a porządnie zamiast regular cadence
2. Delete bez 301 — leaves 404, traci link equity
3. Merge without internal link updates — broken links
4. Update stats only w outdated article — czasem wymaga full rewrite
5. Brak baseline — nie wiesz, czy audit pomógł
6. Ignoring backlinks — page bez ruchu ale z 50 backlinks = nie deletuj
7. One-size-fits-all — different rules dla blog vs landing vs glossary
8. Skipping low-traffic gems — czasem strona z 50 visits/mies. ma 80% conversion (high-value)

Real example: ARDURA Lab content audit (hypothetical)

Stan: 50 blog posts po 6 mies. publikowania.

Audit findings:

• 10 posts (20%) → LEAVE (top 10 dla target queries)
• 20 posts (40%) → UPDATE (pos 10-30, outdated stats)
• 10 posts (20%) → REWRITE (pos 30-50, thin content)
• 5 pairs → MERGE candidates (cannibalization on same topic)
• 5 posts → DELETE (off-topic, zero traffic)

Action plan: 12 weeks, ~5h/tydzień Expected uplift: +35% organic traffic by month 6 post-audit Investment: 60 hours of work ROI: if traffic worth $5/visit (B2B leads), $35K extra revenue/year from this audit
