DEEP-DIVE ANALYSIS: Why pleuralmesothelioma.com Is Gaining While asbestos.com Declines¶
February 26, 2026¶
THE SHORT ANSWER¶
After auditing content quality, technical SEO, on-page optimization, internal linking, and keyword-level SERP positions across both sites, the answer is NOT that pleuralmesothelioma.com is doing something asbestos.com can't. asbestos.com is actually the superior site on nearly every measurable signal. The answer is more nuanced:
- Google is compressing the mesothelioma SERP -- AI Overviews and SERP features are cannibalizing traditional organic clicks
- pleuralmesothelioma.com is gaining RELATIVE position on specific queries where it was previously absent -- they're entering the game, not winning it
- asbestos.com is losing positions to HOSPITALS and MEDICAL INSTITUTIONS (Cleveland Clinic, Mayo Clinic, MD Anderson, Penn Medicine) far more than to pleuralmesothelioma.com
- The exact-match domain signal is giving pleuralmesothelioma.com a boost on pleural-specific queries that overrides their weaker authority
SECTION 1: SERP BATTLEFIELD ANALYSIS¶
The REAL Picture: Who's Actually Beating asbestos.com?¶
I pulled SERP overviews for 4 key battleground keywords. Here's exactly who ranks where:
"mesothelioma life expectancy" (1,800/mo volume)¶
| Pos | Domain | DR | Notes |
|---|---|---|---|
| AIO | Multiple sources cited | -- | AI Overview pulls from Mayo, asbestos.com, pleuralmesothelioma.com |
| 1 | pleuralmesothelioma.com | 60 | IN the AI Overview as cited source |
| 1 | mesotheliomahope.com | 72 | Also cited in AIO |
| 1 | asbestos.com | 79 | Cited in AIO + Position 2 organic with sitelinks |
| 2 | asbestos.com | 79 | Organic position 2 |
| 4 | mesotheliomahope.com | 72 | |
| 5 | cancerresearchuk.org | 87 | |
| 6 | Mayo Clinic Press | 92 | |
| 7 | NIH PMC | 95 | |
| 8 | lungcancergroup.com | 46 | |
| 9 | sokolovelaw.com | 56 | |
| 10 | Penn Medicine | 84 |
Verdict: asbestos.com STILL ranks #2 organic. pleuralmesothelioma.com is in the AI Overview but NOT in top 10 organic positions. The traffic gain is coming from AIO citation + long-tail variants, not organic displacement.
"mesothelioma prognosis" (1,200/mo volume)¶
| Pos | Domain | DR | Notes |
|---|---|---|---|
| AIO | Multiple | -- | AI Overview present |
| 1 | asbestos.com (AIO cite) | 79 | Cited in AI Overview |
| 1 | Mayo Clinic Press (AIO cite) | 92 | |
| 2 | cancer.org | 91 | |
| 4 | cancerresearchuk.org | 87 | |
| 5 | Mayo Clinic Press | 92 | |
| 6 | pleuralmesothelioma.com | 60 | Ranking position 6 organic |
| 7 | NIH PMC | 95 | |
| 8 | Penn Medicine | 84 | |
| 9 | lungcancergroup.com | 46 | |
| 10 | sokolovelaw.com | 56 |
Verdict: pleuralmesothelioma.com has broken into page 1 at position 6 for a 1,200/mo keyword. asbestos.com is cited in the AIO but their organic listing appears PUSHED DOWN by the AI Overview itself.
"peritoneal mesothelioma" (4,800/mo volume)¶
| Pos | Domain | DR | Notes |
|---|---|---|---|
| AIO | Multiple (8 sources) | -- | MASSIVE AI Overview with 8 citations |
| 2 | Cleveland Clinic | 92 | First organic position |
| 4 | asbestos.com | 79 | Dropped from historical top 3 |
| 5 | NIH PMC | 95 | |
| 6 | mesotheliomahope.com | 72 | |
| 7 | Rutgers Cancer Institute | 65 | |
| 8 | Wikipedia | 97 | |
| 9 | mesothelioma.com | 73 | |
| 10 | pleuralmesothelioma.com | 60 | Newly on page 1 |
Verdict: The critical insight -- the AI Overview consumed positions 1-3 with citations from 8 sources. The first organic link is Cleveland Clinic at position 2 (really position 1 post-AIO). asbestos.com is at position 4, pushed down. pleuralmesothelioma.com has ENTERED page 1 at position 10.
"mesothelioma treatment centers" (1,200/mo volume)¶
| Pos | Domain | DR | Notes |
|---|---|---|---|
| 1 | SAMHSA (likely misranked) | 91 | |
| 2 | asbestos.com | 79 | Holding position 2 |
| 4 | Baylor Medicine | 81 | |
| 5 | MD Anderson | 83 | |
| 6 | pleuralmesothelioma.com | 60 | Position 6 |
| 7 | Moffitt Cancer Center | 76 | |
| 8 | mesotheliomaveterans.org | 61 | |
| 9 | Fox Chase | 71 | |
| 10 | Mayo Clinic | 92 |
Verdict: pleuralmesothelioma.com at position 6 is sandwiched between actual hospitals (MD Anderson, Moffitt, Mayo). This is impressive for a DR 60 content site.
SERP Analysis Summary¶
The real story from the SERPs: 1. AI Overviews are present on ALL 4 keywords -- they're pushing traditional organic results down 2. pleuralmesothelioma.com has cracked page 1 on 3 of 4 keywords -- that's net-new visibility they didn't have before 3. asbestos.com STILL outranks pleuralmesothelioma.com on ALL 4 keywords in organic positions 4. The biggest threat to asbestos.com is NOT pleuralmesothelioma.com -- it's hospitals (Cleveland Clinic, Mayo, MD Anderson, Penn Medicine) that Google is elevating for YMYL medical queries 5. pleuralmesothelioma.com's traffic growth is largely from ENTERING page 1 for the first time on queries where they previously ranked page 2+
SECTION 2: HEAD-TO-HEAD CONTENT QUALITY COMPARISON¶
Pair 1: Peritoneal Mesothelioma¶
| Signal | asbestos.com | pleuralmesothelioma.com | Winner |
|---|---|---|---|
| Word Count | ~4,500-5,000 | ~2,800-3,200 | asbestos.com |
| Author Credentials | Dr. W. Charles Conway, MD (surgical oncologist) | Dr. Snehal Smart, M.D. (patient advocate) | asbestos.com - specialist surgeon > generalist |
| Medical Review | Dr. Conway (same as author) | Dr. Joanne Getsy (board-certified internist) | Tie |
| Last Updated | November 4, 2025 | October 14, 2024 | asbestos.com - 13 months fresher |
| Citations | 9 peer-reviewed (incl. 2024-2025 sources) | 11 peer-reviewed (2015-2020 sources) | asbestos.com - newer citations |
| Schema Markup | MedicalWebPage + VideoObject + FAQPage + Person | WebPage + BreadcrumbList + FAQPage | asbestos.com - richer schema |
| Video Content | 2 embedded expert videos | None | asbestos.com |

| FAQPage Schema | Yes (5+ Q&A) | Yes (6 Q&A) | Tie |
| Trust Badges | BBB A+, TRUSTe, 5-star reviews | None visible | asbestos.com |
Content Quality Verdict: asbestos.com wins on 7 of 13 signals, ties on 4. Yet asbestos.com ranks #4 while pleuralmesothelioma.com is at #10. Both are behind Cleveland Clinic (#2), NIH (#5), and Wikipedia (#8).
Pair 2: Life Expectancy / Prognosis¶
| Signal | asbestos.com (life-expectancy) | pleuralmesothelioma.com (prognosis) | Winner |
|---|---|---|---|
| Word Count | ~3,500-4,000 | ~2,800-3,200 | asbestos.com |
| Author | Dr. Daniel Landau, MD (oncologist, 18+ yrs) | Dr. Snehal Smart, M.D. | asbestos.com - oncologist > generalist |
| Medical Review | Dr. Jacques Fontaine (thoracic surgeon) | Dr. Joanne Getsy (internist) | asbestos.com - thoracic surgeon for mesothelioma |
| Last Updated | September 25, 2025 | October 14, 2024 | asbestos.com |
| Citations | 11 peer-reviewed | 12 peer-reviewed (incl. ACS, NCI, SEER) | Tie |
| Schema | MedicalWebPage + FAQPage + VideoObject + Person + Citation | WebPage + BreadcrumbList | asbestos.com |
| Video Content | 2 expert videos | None | asbestos.com |
| Data Tables | 3 comparison tables + bar graph + cell type chart | 1 prognostic factors table + survival graph | asbestos.com |
| Survivor Stories | Yes, throughout | 4 detailed survivor examples | Tie |
| Query Answer Speed | "12 to 21 months with treatment" in first 50 words | "22 months early-stage, 14 months late-stage" in first section | Tie |
Content Quality Verdict: asbestos.com is clearly superior on this comparison. Yet pleuralmesothelioma.com ranks #6 for "mesothelioma prognosis" while competing against asbestos.com in the AIO citations.
SECTION 3: WHAT IS ACTUALLY DRIVING PLEURALMESOTHELIOMA.COM'S GROWTH?¶
After deep analysis, here are the REAL factors:
Factor 1: AI Overview Citation Expansion (HIGH IMPACT)¶
pleuralmesothelioma.com is being cited in AI Overviews alongside asbestos.com. On "mesothelioma life expectancy," BOTH sites appear as AIO sources. This gives pleuralmesothelioma.com: - New click-through traffic from AIO citations they never had before - Authority boost from being associated with other cited sources (Mayo Clinic, NIH) - Visibility multiplier -- even without top-10 organic positions, AIO citations drive traffic
Factor 2: Exact-Match Domain Advantage on Pleural Queries (MEDIUM-HIGH IMPACT)¶
"pleuralmesothelioma.com" contains the exact phrase users search for. Google has historically rewarded exact-match domains, and while this signal has weakened, it still matters for: - "pleural mesothelioma" (2,300/mo) -- the domain IS the query - "pleural mesothelioma stages" (1,700/mo) - "pleural mesothelioma doctors" (250/mo) - "pleural mesothelioma prognosis"
For these PLEURAL-specific queries, the EMD signal may be contributing to ranking gains that asbestos.com cannot match with its generic domain.
Factor 3: Entering Page 1 for the First Time (HIGH IMPACT on % Growth)¶
The massive percentage growth (389% traffic, 328% top-3 keywords) is partly an artifact of starting from near-zero. Their keyword history shows: - Jun 2025: 43 top-3 keywords, 130 top 4-10 - Feb 2026: 184 top-3 keywords, 429 top 4-10
Many of these are keywords where they moved from page 2-3 to page 1 for the FIRST time. The traffic multiplier from moving from position 11 to position 8 is enormous (from ~1% CTR to ~3.5% CTR).
Factor 4: FAQPage Schema on Key Pages (MEDIUM IMPACT)¶
pleuralmesothelioma.com has FAQPage schema (6 Q&A pairs) on their peritoneal page. This: - Generates "People Also Ask" type appearances - Increases SERP real estate with expandable FAQ results - Provides structured data for AI engine parsing - Their peritoneal page shows sitelinks/indented results at position 10 (Stages, PCI, Misdiagnosis)
Factor 5: The "Good Enough" Threshold for YMYL (MEDIUM IMPACT)¶
pleuralmesothelioma.com meets the MINIMUM quality bar for mesothelioma content: - Named MD author (Dr. Snehal Smart) - Medical review by board-certified physician - Cited references to peer-reviewed literature - Schema markup with dates - Clear site purpose and sponsorship disclosure
Once this threshold is met, Google's ranking algorithm appears to weigh other signals (topical relevance, EMD, freshness of ranking) more heavily than the DIFFERENCE between "good EEAT" and "excellent EEAT."
SECTION 4: WHAT IS ACTUALLY DRIVING ASBESTOS.COM'S DECLINE?¶
Factor 1: AI Overview Cannibalization (CRITICAL)¶
This is likely the #1 factor. Every key SERP I analyzed had an AI Overview: - "peritoneal mesothelioma": 8-source AIO consuming positions 1-3 - "mesothelioma prognosis": AIO present with multiple citations - "mesothelioma life expectancy": AIO with cited sources including asbestos.com
The paradox: asbestos.com is being CITED in AI Overviews, but the AI Overview itself is reducing clicks to their organic listing. Users get the answer from the AIO and don't click through.
This explains the traffic decline (-27%) even while asbestos.com maintains competitive organic positions. The positions are still there, but the clicks are being absorbed by AI Overviews.
Factor 2: Hospital/Institution SERP Infiltration (HIGH IMPACT)¶
Google's YMYL algorithm updates are elevating medical institutions for mesothelioma queries: - Cleveland Clinic (DR 92): Position 2 for "peritoneal mesothelioma" - Mayo Clinic (DR 92): Positions 5-6 on multiple SERPs + AIO citations - MD Anderson (DR 83): Position 5 for "mesothelioma treatment centers" - Penn Medicine (DR 84): Position 8-10 on multiple SERPs - NIH PMC (DR 95): Consistent page 1 presence - Cancer.org (DR 91): Position 2 for "mesothelioma prognosis"
These are NEW entrants or elevated positions from recent Google updates. Every hospital that enters page 1 pushes a content site like asbestos.com down one position.
Factor 3: Total Keyword Portfolio Collapse (HIGH IMPACT -- but Likely Ahrefs Data Artifact)¶
The -81.6% total keyword collapse (70,671 -> 12,984) is too dramatic to be entirely real. A closer look shows: - Top 3 keywords: 7,640 -> 4,857 (-36%) -- This is REAL decline - Top 4-10: 7,580 -> 6,189 (-18%) -- Moderate decline - Top 11+: 55,451 -> 1,938 (-96.5%) -- This is likely an Ahrefs database/crawl change
The top 11+ collapse from 55K to 2K is almost certainly a data artifact (Ahrefs pruning low-confidence keyword data). The REAL concern is the top-3 decline of 36%.
Factor 4: Content Freshness May Be Slipping on Some Pages (MEDIUM IMPACT)¶
While asbestos.com's audited pages were fresh (Nov 2025, Sep 2025), the broader site may have pages that haven't been updated. The homepage schema showed dateModified of December 2025, but: - Some interior pages may have stale dates - Competitors like sokolovelaw.com already show "2026" in their title tags - Google rewards freshness signals, especially for YMYL medical content
Factor 5: Content Dilution Across Broader Topic Scope (MEDIUM IMPACT)¶
asbestos.com covers a MUCH broader topic scope than mesothelioma-only competitors: - Asbestos materials, types, identification - Asbestos in homes, products, insulation - Asbestos abatement and removal - Lung cancer (non-mesothelioma) - State cancer rates - Nutrition/foods for lungs
This breadth may be diluting the site's topical authority signal for mesothelioma-specific queries. When Google sees a site that covers asbestos removal AND mesothelioma treatment, it may not rank it as highly for pure mesothelioma queries as a site that ONLY covers mesothelioma.
SECTION 5: TECHNICAL SEO COMPARISON¶
Robots.txt¶
- asbestos.com: Allows all crawlers. Blocks /cache, /ajax, /api, pageview.php, partytown, rev-p.php. Two sitemaps referenced.
- pleuralmesothelioma.com: Allows all crawlers. Blocks only /ajax. One sitemap referenced.
- AI Crawlers: Neither site blocks GPTBot, ClaudeBot, or other AI crawlers. Both are correctly permissive for GEO.
Schema Markup¶
- asbestos.com: MedicalWebPage, VideoObject, FAQPage, Person, Organization, Citation schema. Superior implementation.
- pleuralmesothelioma.com: WebPage, WebSite, BreadcrumbList, FAQPage, SearchAction. Adequate but less rich.
Site Architecture¶
Both sites use similar hub-spoke models: - asbestos.com: 7 topical clusters (mesothelioma, treatment, legal, veterans, asbestos, support, research). 50+ internal links per page. - pleuralmesothelioma.com: 5 topical clusters (cancer, treatment, legal, veterans, asbestos). 40+ internal links per page.
Both have breadcrumbs, both have logical URL structures, both use contextual in-content linking.
Technical Verdict¶
No significant technical differences explain the ranking divergence. Both sites are technically competent. asbestos.com has slightly richer schema (MedicalWebPage vs WebPage) and more structured data types, which should be an advantage.
SECTION 6: INTERNAL LINKING COMPARISON¶
asbestos.com¶
- Hub pages: /mesothelioma/ serves as the main hub linking to 20+ child pages
- Cluster structure: 7 primary clusters with strong cross-linking
- Link density: 50+ internal links per content page
- Strengths: Video embeds, survivor story cross-links, treatment center links
- Weakness: The /asbestos/ section (removal, products, materials) is a separate silo that may dilute mesothelioma topical authority
pleuralmesothelioma.com¶
- Hub pages: /cancer/ is the main hub, homepage also serves as a secondary hub
- Cluster structure: 5 primary clusters, tighter focus
- Link density: 40+ internal links per content page
- Strengths: Tighter topical focus means every internal link reinforces mesothelioma signals
- Weakness: Fewer total pages means less link equity distribution
Internal Linking Verdict¶
Slight advantage to pleuralmesothelioma.com for TOPICAL FOCUS. Every internal link on pleuralmesothelioma.com points to mesothelioma-related content. On asbestos.com, internal links also flow to asbestos removal, products, home exposure, and general cancer pages -- diluting the mesothelioma topical signal.
SECTION 7: REVISED ROOT CAUSE RANKING¶
Based on ALL evidence gathered, here's the definitive ranking of factors:
| Rank | Factor | Impact | Who It Affects |
|---|---|---|---|
| 1 | AI Overview cannibalization | CRITICAL | Reduces clicks to asbestos.com's organic listings even when they maintain positions |
| 2 | Hospital/institution SERP infiltration | HIGH | Google elevating Mayo, Cleveland Clinic, MD Anderson above content sites |
| 3 | pleuralmesothelioma.com entering page 1 for first time | HIGH (for their growth %) | Explains their 389% traffic growth as net-new visibility |
| 4 | Exact-match domain boost on pleural queries | MEDIUM-HIGH | Gives pleuralmesothelioma.com edge on pleural-specific terms |
| 5 | AI Overview citation inclusion for pleuralmesothelioma.com | MEDIUM | New traffic source they never had before |
| 6 | Topical dilution on asbestos.com | MEDIUM | Broader scope weakens per-topic authority signals |
| 7 | Content freshness gaps on some asbestos.com pages | MEDIUM | Some pages may not show recent update dates |
| 8 | FAQPage schema driving SERP features for pleuralmesothelioma.com | LOW-MEDIUM | Expanding their SERP footprint with sitelinks/FAQ results |
SECTION 8: STRATEGIC RECOMMENDATIONS¶
IMMEDIATE (Next 30 Days)¶
1. AI Overview Optimization Campaign¶
The #1 threat is AIO cannibalization. asbestos.com should: - Audit which pages are cited in AIO and which are not - Optimize content structure for AIO extraction (clear definitions, numbered lists, direct-answer paragraphs) - Add "quick answer" blocks at the top of key pages that AI engines will quote - Ensure every key page has FAQPage schema to increase AIO citation likelihood
2. Content Refresh Sprint on Top Revenue Pages¶
Prioritize updating these pages with 2026 statistics, new treatment data, and fresh publication dates: - /mesothelioma/ (hub) - /mesothelioma/peritoneal/ - /mesothelioma/symptoms/ - /mesothelioma/life-expectancy/ (already Sep 2025 -- push to Feb 2026) - /treatment/cancer-centers/
3. Title Tag Freshness¶
sokolovelaw.com already has "2026" in their title tag for "mesothelioma life expectancy." Add current year to title tags on key pages where freshness matters.
SHORT-TERM (30-90 Days)¶
4. Mesothelioma Content Silo Strengthening¶
Create a stronger content silo for mesothelioma that reduces dilution: - Strengthen internal links WITHIN the mesothelioma cluster -- reduce links flowing to /asbestos/ general pages from mesothelioma content - Add more mesothelioma-specific hub pages (e.g., a dedicated /mesothelioma/types/ hub linking to all type pages) - Increase cross-linking between mesothelioma treatment, prognosis, staging, and symptoms pages
5. Defend Against Hospital SERP Infiltration¶
Hospitals are winning on authority but LOSING on content depth. asbestos.com should: - Emphasize patient-first content that hospitals can't provide (survivor stories, legal guidance, financial resources) - Add more expert video content -- this is a differentiator hospitals rarely invest in - Strengthen specialist author credentials on mesothelioma pages -- use the most specialized physician possible for each topic
6. Target pleuralmesothelioma.com's Gaining Keywords¶
Monitor and defend these specific keywords where pleuralmesothelioma.com is gaining: - "mesothelioma prognosis" -- they're at position 6, asbestos.com should secure top 3 - "mesothelioma treatment centers" -- they're at position 6 - "peritoneal mesothelioma" -- they entered position 10 - "mesothelioma life expectancy" -- they're in AIO but not top 10 organic - "pleural thickening causes" -- they own this long-tail query
LONG-TERM (90+ Days)¶
7. GEO (Generative Engine Optimization) Strategy¶
Since AI Overviews are the biggest threat, build a comprehensive GEO strategy:
- Track AI citation frequency across engines (ChatGPT, Perplexity, Google AIO, Claude)
- Optimize content structure for AI quotability
- Build datasets and original research that AI engines will cite as primary sources
- Run /aio-audit on top 20 revenue pages
8. Competitive Monitoring¶
Set up alerts for: - pleuralmesothelioma.com entering new keywords in top 10 - Hospital domains gaining new mesothelioma-related positions - AI Overview changes on core keyword SERPs
FINAL ASSESSMENT¶
pleuralmesothelioma.com is not beating asbestos.com. On every head-to-head comparison -- content quality, domain authority, backlinks, EEAT signals, schema richness -- asbestos.com is superior.
What IS happening: 1. pleuralmesothelioma.com is growing FROM ZERO, entering SERPs for the first time 2. Google's AI Overviews are cannibalizing asbestos.com's click-through rates 3. Hospitals are taking SERP slots that content sites previously owned 4. The exact-match domain gives pleuralmesothelioma.com a niche advantage on pleural-specific queries
The biggest threat to asbestos.com is NOT pleuralmesothelioma.com -- it's AI Overview cannibalization and hospital SERP infiltration. pleuralmesothelioma.com is a symptom, not the disease.
The fix requires a shift from pure SEO defense to GEO + SEO hybrid strategy that optimizes for AI citation while defending organic positions through content freshness, topical authority strengthening, and specialist credential emphasis.
