Sister briefs: [[research-brief-smb-widget-capture-layer-june-2026]], [[research-brief-smb-widget-spend-benchmarks-june-2026]], [[research-brief-smb-widget-difficulty-to-work-june-2026]], [[research-brief-smb-widget-presenting-tiers-june-2026]], [[research-brief-smb-widget-market-difficulty-june-2026]]. Cluster entry point: [[research-cluster-smb-difficulty-widget-june-2026]].\n\n## TL;DR\n\n- Digital competitive difficulty varies enormously and predictably by vertical: **legal, insurance/financial, and SaaS/B2B sit at the hard extreme; trades / home services and dentistry are \"hard-local\"** (crowded local packs, high review bars, expensive clicks); **restaurants are review-saturated but content-unsophisticated;** and **accounting, niche B2B/industrial, and many professional-services sub-niches remain comparatively open**. Confidence in this *rank-ordering* is **Industry-consensus** — directionally robust but built largely on vendor data.\n- The single best-evidenced proxy is **cost-per-click (CPC)**: [WordStream/LocaliQ](https://www.wordstream.com/blog/ws/2024/02/22/search-advertising-benchmarks)'s 2025 data puts Legal at $8.58 and Dentists and Home Improvement both at $7.85, versus Restaurants at $2.05 — a 4.18x spread (Legal $8.58 vs Restaurants $2.05) that tracks willingness-to-pay and therefore commercial contestedness. All CPC data is **vendor-sourced and quarantined** (see dedicated section).\n- For a self-assessment widget, the defensible output is **TIERS, not numbers.** We recommend a 4-tier model (Hyper-competitive / Hard-local / Moderate / Open) with two independent axes — *commercial intensity* (CPC/keyword difficulty) and *local saturation* (review bar + pack crowding) — because a plumber and a SaaS company are both \"hard\" for completely different reasons.\n\n## Key Findings\n\n**1. The evidence is real but impressionistic; three evidence bases must be kept separate.**\n\n- (a) **How competitiveness is DEFINED/proxied**: CPC (commercial willingness-to-pay), keyword difficulty (organic backlink/authority barrier), local-pack saturation (number of credible competitors for 3 slots), and review-count bars (credibility threshold). **Industry-consensus.**\n- (b) **EVIDENCE the differences are real**: convergent vendor datasets (WordStream, [Semrush](https://www.semrush.com/), BrightLocal, [Local Falcon](https://www.localfalcon.com/), Whitespark) independently show the same ordering — e.g., legal is expensive on CPC *and* hard organically *and* high-LTV. Convergence across commercially-independent metrics is the strongest evidence we have. **Industry-consensus.**\n- (c) **MAGNITUDE and limits**: CPC spreads are ~4-5x across mainstream verticals (WordStream) and up to 20x at the extremes (Semrush/Digital Position); review bars range from ~2 reviews (home health care) to 227+ entry (breakfast restaurants) per Local Falcon. But there is **no neutral, academic, or government dataset** that directly measures \"digital competitiveness by SMB vertical.\" This is a genuine evidence gap (see Caveats).\n\n**2. CPC rank-ordering (vendor-sourced, quarantined, directional proxy):** Legal/attorneys > Insurance/Finance (esp. wealth management, auto insurance) > Dentistry/medical cosmetic > Home improvement/trades > B2B/Business services > Education > Real estate (surprisingly low now) ≈ Healthcare general > Retail/e-commerce > Restaurants/food > Arts/entertainment. **Industry-consensus among vendors; treat exact values as indicative.**\n\n**3. Organic keyword difficulty is structurally highest where YMYL + national competitors + portal dominance converge:** finance/insurance, legal, real estate (Zillow/Realtor.com), and e-commerce (Amazon) are hardest organically. SaaS/B2B is hard because competitors are venture-funded with dedicated content teams. Local trades and restaurants are organically *easier* because competition is geographically bounded. **Industry-consensus.**\n\n**4. Local-pack saturation and review bars define a separate \"hard-local\" axis.** Per Local Falcon's analysis, the median review count to rank in the 3-pack ranges from ~2 (home health care) to 200-265 (plumbers/HVAC/pest control) to 227+ entry for breakfast restaurants, while lawyers/accountants need only ~40-54. Big cities require ~1.5-2x rural counts. **Single-source (Local Falcon), vendor-quarantined.** See [[local-falcon-2025-review-bars-by-category]].\n\n**5. Review credibility bars differ sharply by category** and consumer expectations are rising fast: BrightLocal's 2026 Local Consumer Review Survey (1,002 US adults) reports 68% will only use a business with four or more stars (up from 55% in 2025), and 31% now require 4.5+ (up from 17% last year). High-volume categories (restaurants, hotels) carry hundreds of reviews but lower average stars (~4.0-4.1); relationship trades and salons run higher (4.5-4.6). **Industry-consensus, vendor-sourced.** See [[consumer-rating-thresholds-rising-brightlocal]] and [[brightlocal-rating-norms-by-category]].\n\n**6. Content/SEO maturity (sophistication of incumbents) is the most under-measured axis.** Legal, SaaS, insurance, and real estate have sophisticated, saturated digital competition; many trades, local medical, accounting, and B2B/industrial niches remain relatively unsophisticated and open to a well-built entrant. This is the dimension with the **thinnest hard evidence (Directional-Speculative)** but the most strategic value. See [[content-seo-maturity-by-vertical]].\n\n## Details\n\n### Rough rank-ordering of verticals, most ↔ least digitally competitive\n\n*(Confidence in the ordering itself: **Industry-consensus**. It is a synthesis of vendor CPC, keyword-difficulty commentary, and local-pack/review studies — not a measured index. Two businesses can occupy the same tier for opposite reasons.)*\n\n| Tier | Verticals | Why hard / Dominant difficulty driver |\n|---|---|---|\n| **1 — Hyper-competitive** | Legal (esp. personal injury), Insurance, Financial/wealth advisory, SaaS/B2B software | Extreme CPC + extreme keyword difficulty (YMYL, national + funded competitors). High LTV justifies aggressive bidding. — [[tier-1-hyper-competitive-verticals]] |\n| **2 — Hard-local** | Dentistry & cosmetic medical, Home services/trades (plumbing, HVAC, electrical, roofing), Real estate agents | High local-pack saturation, high review bars, high CPC — but geographically bounded so a well-run local entrant can win. — [[tier-2-hard-local-verticals]] |\n| **3 — Moderate** | General healthcare/physio/clinics, Retail & local e-commerce, Restaurants/cafes/hospitality | Restaurants: review-saturated but content-unsophisticated. Retail: crushed by Amazon nationally, winnable locally. — [[tier-3-moderate-verticals]] |\n| **4 — Relatively open** | Accounting/bookkeeping, Many B2B/industrial/manufacturing niches, Landscaping, specialized professional services | Lower CPC, lower review adoption, less sophisticated incumbents — most open to a well-built digital entrant. — [[tier-4-open-verticals]] |\n\n### Q1 & Q2 — Cross-vertical search competitiveness and CPC as a proxy\n\nCPC is the single most consistently reported and cross-validated proxy. The logic: advertiser willingness-to-pay reflects how contested and how lucrative a market is. **All figures below are vendor-sourced (quarantined).**\n\n**WordStream/LocaliQ 2025 (Google Search, ~16,446 US campaigns, Apr 2024-Mar 2025; medians):** — see [[wordstream-2025-cpc-benchmarks]]\n\n- Highest CPC: Attorneys & Legal Services **$8.58**; Dentists & Dental Services **$7.85**; Home & Home Improvement **$7.85**; Education & Instruction **$6.23**; Business Services **$5.58**; Physicians & Surgeons **$5.00**.\n- Lowest CPC: Arts & Entertainment **$1.60**; Restaurants & Food **$2.05**; Travel **$2.12**; Real Estate (notably low now).\n- Highest cost-per-lead: Attorneys **$131.63**; Furniture **$121.51**; Business Services **$103.54**; Real Estate **$100.48**.\n- Overall average CPC: **$5.26**, up 12.88% YoY. (LocaliQ attributes part of the rise to smart-bidding campaigns where Google has more direct control over CPCs.) The Legal-to-Restaurant spread is **4.18x** ($8.58 vs $2.05).\n\n**WordStream 2024 (prior year, for trend):** Attorneys $8.94, Home Improvement $6.96, Dentists $6.82. See [[wordstream-2024-cpc-prior-year-baseline]].\n\n**WordStream 2026 (sample of 13,474 US campaigns, Apr 2025-Mar 2026):** highest CPCs were Attorneys and Legal Services **$9.87**, Home and Home Improvement **$8.33**, and Dentists and Dental Services **$8.00** — legal/home/dental remain the top 3 every year, which is itself strong evidence the ordering is stable. See [[wordstream-2026-cpc-trend]].\n\n**Semrush / Digital Position (\"2024 Google Ads CPC Benchmarks: Insights from 3.6M Keywords,\" 66 categories):** average US CPC $4.18; \"CPCs can differ by as much as 20X.\" Handyman Services topped the charts at a \"staggering\" **$19.78**; Colleges/Universities $9.13; Air Charter $1.76 (low intent despite niche). See [[semrush-cpc-20x-spread]].\n\n**Semrush CPC Map (2019-2020, via MarketingCharts):** Insurance highest at **$18.57**; Online Education $14.04; Marketing/Advertising $7.40; Legal $6.97. Electronics lowest at $0.83. See [[semrush-2019-2020-insurance-18-cpc]].\n\n**Envoca (vendor) on intra-vertical spread:** within legal, average ~$5.27 but \"auto accident lawyer\"/\"medical malpractice attorney\" can exceed **$200** per click in competitive markets; financial services ~$5.48 average but wealth management ~$31.31; insurance can reach $76.54 for first position. See [[envoca-extreme-cpc-within-vertical]].\n\n**Interpretation (Industry-consensus):** The famous \"legal and insurance are most expensive\" claim is well-supported across multiple vendor datasets spanning 2019-2026. CPC is a *commercial-intensity* proxy: it captures contestedness and LTV, NOT organic ranking difficulty or local-pack crowding (a plumber's $7.85 CPC reflects high job value, but the plumber still only competes locally).\n\n### Q3 — Keyword difficulty norms by sector (organic)\n\nKeyword difficulty (KD) is a 0-100 proprietary score ([Ahrefs](https://ahrefs.com/), Semrush, [Moz](https://moz.com/)) estimating organic ranking difficulty, driven largely by the backlink authority of incumbents. **All KD tooling is vendor-sourced.** See [[keyword-difficulty-as-triage-only]].\n\n- **Structurally hardest organic sectors (Industry-consensus):** Finance/insurance, legal, real estate, and e-commerce. Drivers: (1) YMYL — Google demands exceptional E-E-A-T for money/health/legal topics; (2) national + deep-pocketed competitors; (3) portal/marketplace dominance (Amazon in retail; Zillow, Realtor.com, Redfin, Homes.com in real estate — Zillow alone ranks for 4.5M+ keywords).\n- **SaaS/B2B software (Industry-consensus):** structurally hard because incumbents ([HubSpot](https://www.hubspot.com/), Salesforce, Monday, Asana) are venture-funded with dedicated content teams; head terms like \"CRM software\" have dozens of funded competitors. Standard playbook is to retreat to long-tail (KD <20) and comparison/bottom-funnel pages.\n- **Local services (trades, restaurants, local medical) (Industry-consensus):** organically *easier* in absolute terms because the competitive set is geographically bounded — a Kansas City plumber competes with other KC plumbers, not the nation. The battle shifts from classic organic to the local pack.\n- **Key structural point (Industry-consensus):** KD and CPC are correlated but distinct. CPC reflects commercial value; KD reflects authority barrier. A vertical can be high-CPC but locally winnable (plumbing) or moderate-CPC but organically brutal (real estate, now ~$2 CPC but Zillow-dominated). Also note KD scores differ across tools (same keyword can score, e.g., 42 in Ahrefs, 58 in Semrush, 65 in Moz) because each uses a different proprietary formula.\n\n### Q4 — Local pack saturation by category\n\nOnly 3 slots exist in the Google local pack, and SOCi (a multi-location marketing vendor) reports local-pack visibility drives ~126% more traffic and ~93% more actions than ranking below ([[spp-soci-126-percent-local-pack-traffic-uplift]]) — a figure that originates with SOCi's own product marketing and should be treated as vendor-quarantined. Saturation = how many credible competitors chase those 3 slots.\n\n**Local Falcon whitepaper (\"What 50 Million Search Results Reveal About Ranking in the Local 3-Pack,\" 50.4M search results, 1,993 categories, Q4 2025) — median reviews to rank in 3-pack (Single-source, vendor-quarantined):** see [[local-falcon-2025-review-bars-by-category]]\n\n- Home health care: ~**2** (wide-open)\n- Lawyers / accountants: ~**40-54** (low-volume local categories)\n- Dentists: ~**180** rural median (more in metros)\n- Plumbers / HVAC / pest control: **200-265**\n- Breakfast restaurants: **227** entry-level\n- General pattern: median 50-300 reviews to be \"typical\"; **500-1,500+** to dominate; metros need ~1.5-2x rural counts; entry-to-dominant gap can be 30-80x.\n\n**[Whitespark 2026](https://whitespark.ca/local-search-ranking-factors/) Local Search Ranking Factors (47 experts) — local-pack ranking weights (vendor-sourced):** GBP signals **32%**, Review signals **20%**, On-page **15%**, Behavioral **9%**, Links **8%**, Citations **6%**, Social **5%**. Top three individual factors: primary GBP category, proximity to searcher, keywords in GBP business title. Reviews rose from 16% (2023) to 20% (2026); review *recency* is increasingly weighted. See [[whitespark-2026-local-ranking-factors]].\n\n**Interpretation:** \"Saturation\" has two components — (1) how many competitors (trades, restaurants, dentists in metros = crowded; home health, accountants, niche B2B = sparse), and (2) how high the review bar to be credible. These move together for trades and restaurants (crowded + high bar) but diverge for lawyers (sparse pack, low review bar, but high CPC/organic difficulty).\n\n### Q5 — Review-count and rating expectations by category\n\n**[BrightLocal Google Reviews Study](https://www.brightlocal.com/research/google-reviews-study/) (93,000 businesses, 26 industries):** overall average 39 reviews; top-3 local businesses average **47**; average star rating 4.42. Most reviews: hotels/B&Bs, restaurants, bars, local stores, car dealerships. Fewest: **accountants/finance** (least likely to even have reviews), landscaping, senior living, marketing/PR, construction/roofing. Notably, ~20% of businesses ranking in the top 3 had *no* reviews — confirming other factors matter. See [[brightlocal-rating-norms-by-category]].\n\n**Rating norms by category (vendor-sourced, Industry-consensus):** Home services and salons highest (~4.5-4.6); beauty/hair ~4.5; fitness ~4.4; legal ~4.3; healthcare/dental ~4.1; restaurants ~4.1; hotels ~4.0; car dealerships and senior living lowest. High-volume/high-variability businesses (restaurants, hotels) carry many reviews but lower stars; relationship businesses (trades, dental, salons) carry fewer-to-moderate reviews but higher stars.\n\n**Rising bar (BrightLocal [Local Consumer Review Survey 2026](https://www.brightlocal.com/research/local-consumer-review-survey/), 1,002 US adults via SurveyMonkey):** 68% will only use a business with four or more stars (up from 55% in 2025); 31% now require 4.5+ (up from 17% last year). Review *recency* matters more than ever (85% think reviews >3 months old are no longer relevant). See [[consumer-rating-thresholds-rising-brightlocal]].\n\n**Velocity point (Industry-consensus):** Across categories the operative competitive metric is increasingly *review velocity* (new reviews per month) vs. competitors, not absolute count — emergency trades (plumbing) show the highest velocity demands; low-volume professional services the lowest. Whitespark places review recency among its most underrated 2025 ranking factors. See [[sterling-sky-review-velocity-case-study]] in sister brief [[research-brief-smb-widget-market-difficulty-june-2026]].\n\n### Q6 — Content/SEO maturity by sector\n\nThis is the axis most relevant to \"is there room for a well-built entrant\" — and the thinnest in hard data (largely **Directional-Speculative**, inferred from agency commentary). See [[content-seo-maturity-by-vertical]].\n\n- **Sophisticated / saturated (hard to enter even if you build well):** Legal, SaaS/B2B, insurance/finance, real estate. Incumbents run content teams, programmatic SEO (e.g., Zapier integration pages, SaaS comparison hubs), and deep backlink profiles.\n- **Mixed:** Dentistry and multi-location healthcare/retail are professionalizing fast (DSOs, franchises with dedicated marketing).\n- **Relatively unsophisticated / open:** Many trades, independent local medical (physio, single-clinic), accounting/bookkeeping, landscaping, and B2B/industrial/manufacturing. Trades commentary repeatedly notes most trade websites are thin \"we do everything\" single-pagers — a well-built site with proper service/location pages and a review engine can outrank incumbents relatively quickly.\n- **Canadian context (BLUF for Canada):** The opportunity is structurally larger in Canada because adoption is shallower. [CFIB](https://www.cfib-fcei.ca/)'s \"Your Voice\" survey (fielded Sept 11-25, 2025; n=2,478) found 92% of Canadian SMBs use digital tools but only **10%** have fully integrated them across operations; nine in ten use at least one digital channel, including a company website (78%) and Google Business Profile/Maps (52%). [Statistics Canada](https://www.statcan.gc.ca/) (2021): 89% of businesses with 5+ employees have some web presence but only ~19% do email marketing; [BDC](https://www.bdc.ca/) estimates only ~1 in 5 has an \"advanced digital profile.\" **Verified (government/CFIB primary sources).** See [[canadian-smb-digital-adoption-gap]]. Implication: in Canada, even competitive verticals have more unsophisticated incumbents, widening the entry window.\n\n## The quarantine: vendor-originated sources and their commercial incentives\n\nEvery quantitative cross-vertical dataset in this report comes from a commercial vendor. None is neutral, academic, or governmental. Treat all figures as **indicative, not precise.**\n\n| Source | Data used | Commercial incentive (why quarantined) |\n|---|---|---|\n| **WordStream / LocaliQ** | CPC, CPL, CTR, CVR by industry (2024-2026) | Sells PPC management & software; benchmarks market its \"free Google Ads Grader\" and agency services. Incentive to frame paid search as essential. Data is median of *its own managed/sampled accounts* (selection bias toward active advertisers). |\n| **Semrush** | CPC map, keyword difficulty | Sells SEO/PPC SaaS subscriptions; KD score is proprietary and a product feature. Incentive to make difficulty legible (and to sell the tool that measures it). |\n| **Ahrefs / Moz** | Keyword difficulty methodology | Sell SEO tools; KD is a flagship metric. Each uses a different proprietary formula — scores don't match across tools. |\n| **Digital Position, Envoca, Focus Digital, Ryze, WebFX, etc.** | CPC benchmarks (secondary aggregations) | Agencies/tools republishing WordStream/Semrush data to attract clients. Often recycle the same underlying vendor numbers — apparent \"corroboration\" can be circular. |\n| **BrightLocal** | Review counts, star ratings, local consumer survey | Sells local SEO/review tools; research is lead-gen content. Consumer survey is self-reported panel (SurveyMonkey, ~1,000 US adults). Business dataset skews to BrightLocal's audience (US/CA/AU/UK). |\n| **Local Falcon** | Median reviews to rank in 3-pack by category | Sells local rank-tracking software; whitepaper funnels to \"find your category benchmark\" tool. Category figures locked in a gated interactive tool (not independently verifiable). |\n| **Whitespark** | Local Search Ranking Factors weightings | Sells local SEO software/services (Edmonton, Canada). Survey of 47 hand-selected experts = opinion aggregation, not measured ranking weights. |\n| **SOCi** | Local pack traffic/action uplift (126%/93%) | Sells multi-location marketing platform; stat markets its product. |\n\n**Two systemic biases to flag:**\n\n1. **Survivorship/selection bias:** Vendor data reflects *active advertisers and businesses with managed digital presence* — not the full population of SMBs (many of whom have no website or unclaimed GBP). This *overstates* baseline competitiveness in every vertical, especially the \"open\" ones.\n2. **Circular corroboration:** Many \"independent\" CPC benchmark posts simply republish WordStream or Semrush numbers. Apparent agreement across a dozen sites can trace to one or two original datasets.\n\n**Where neutral data does NOT exist (explicit gap):** There is no government, academic, or independent third-party dataset that measures *digital/search competitiveness by SMB vertical*. Government sources (Statistics Canada, US Census/BLS) measure industry concentration, firm counts, and digital *adoption*, but not search/local competitiveness. Any cross-vertical competitiveness claim therefore rests on vendor proxies plus reasoning — a fact a responsible widget should disclose.\n\nConsolidated caveats: [[caveats-vendor-quarantine-vertical-difficulty]].\n\n## Recommendations: turning \"vertical\" into a difficulty-tier input without overclaiming\n\n**Stage 1 — Adopt a two-axis tier model, not a single score.** A plumber and a SaaS company are both \"hard\" for opposite reasons; a one-number difficulty score destroys that information. Use two independent axes:\n\n- **Axis A — Commercial intensity** (proxy: CPC tier + organic KD). Captures legal/insurance/SaaS.\n- **Axis B — Local saturation** (proxy: typical 3-pack review bar + pack crowding). Captures trades/restaurants/dentists.\n\nOutput a tier per axis, then a combined label. Example outputs: Legal = \"High commercial / Low-moderate local.\" Plumber = \"Moderate-high commercial / High local.\" Accountant = \"Low commercial / Low local = OPEN.\" SaaS = \"High commercial / N/A local.\" Codified as [[rule-output-two-axis-tier-not-one-number]]. See [[two-axis-vertical-tier-model]].\n\n**Stage 2 — Bucket every business type into 4 coarse tiers per axis.** Resist precision. Use Tier 1-4 (or Hard/Moderate/Open) anchored to the ranges in this report. Map the widget's \"what kind of business are you?\" picklist to these buckets via a maintained lookup table (GBP primary categories are a natural taxonomy to borrow). Where a vertical splits (e.g., personal injury law vs. estate planning; cosmetic vs. general dentistry), allow a sub-question — codified as [[rule-allow-vertical-sub-segmentation]].\n\n**Stage 3 — Calibrate thresholds to local reality at runtime where possible.** The strongest single upgrade: if the user gives a city, the widget can note \"metros need ~1.5-2x the review count of rural areas\" and adjust the local-saturation tier. Absent location, present the rural/metro range. Codified as [[rule-calibrate-thresholds-to-local-reality]].\n\n**Stage 4 — Show the bar as a range with confidence, and disclose sourcing.** e.g., \"Plumbers typically need ~200-265 Google reviews to rank in the top 3 locally (vendor estimate, Local Falcon; varies 1.5-2x by city).\" Always label the tier's confidence and that figures are vendor-derived. This converts a weakness (impressionistic data) into a trust signal. Codified as [[rule-vendor-data-as-vendor-estimate-with-range]].\n\n**Benchmarks/thresholds that should change the tiering:**\n\n- If a neutral/academic dataset on vertical digital competitiveness emerges → reduce reliance on CPC proxy and re-weight.\n- If a vertical's CPC moves >25% YoY (e.g., Real Estate dropped sharply as Performance Max shifted spend) → re-bucket its commercial axis.\n- If consumer rating thresholds keep climbing (4+ star requirement went 55%→68% in one year) → raise the local-credibility bar across all local tiers annually.\n- If the user's own review count is within ~1 month's velocity of the category median → classify as \"competitive,\" not \"behind\" (velocity, not absolute count, is the operative gap).\n\n**Practical default for the widget:** Lead with the *tier and the reason* (\"Hard — because your local pack is crowded and customers expect 200+ reviews\"), give a *range* not a number, label it *vendor-estimated*, and offer the *open-vertical encouragement* where it applies (accounting, niche B2B, many trades in Canada) — that is both honest and the most motivating message for an SMB owner.\n\n## Caveats\n\n- **The rank-ordering is Industry-consensus, not Verified.** It synthesizes convergent vendor datasets; it is not a measured competitiveness index. No such index exists.\n- **All quantitative cross-vertical data is vendor-sourced and quarantined.** CPC, KD, review bars, and ranking-factor weights all carry commercial incentives and selection/survivorship bias toward active digital participants. Use as directional proxies only.\n- **CPC ≠ organic difficulty ≠ local saturation.** Conflating them is the most common analytical error; real estate is the clearest example (low CPC, brutal organic).\n- **Content/SEO maturity (Q6) is the thinnest-evidenced axis** — largely Directional-Speculative from agency commentary — yet the most decisive for \"can a well-built entrant win.\" Flag it as judgment, not data.\n- **Recency/volatility:** CPCs and ranking factors shift yearly (AI Overviews, Performance Max, rising review thresholds). Any tiering needs an annual refresh cadence.\n- **Geography:** Most data is US-centric. Canadian-specific competitiveness data is sparse; the strongest Canadian signal is *lower digital maturity* (CFIB: only 10% fully integrated; StatCan/BDC: ~1 in 5 \"advanced\"), which widens entry windows but is an adoption metric, not a competitiveness metric.\n- **Within-vertical variance can exceed between-vertical variance.** \"Personal injury lawyer\" ($200+ CPC) vs. a niche estate attorney; cosmetic vs. general dentistry; downtown vs. rural. Tiers must allow sub-segmentation or they will mislead.\n\nConsolidated caveats entry: [[caveats-vendor-quarantine-vertical-difficulty]].\n","rationale_body":"Compiled June 2026.
