Nonverbia’s public site makes the product easy to place: it is conversation intelligence for sales professionals and teams, with a clear focus on tone, attention, engagement, and buyer signals. The prospect journey is well covered, with category, audience, pricing, trial, integrations, security, meeting coverage, and differentiation represented in the crawl.

The strongest measured areas are accessibility at 88/100, audience and messaging at 84/100, and first impressions and positioning, usability, risk and stability, and technical SEO at 82/100 each. The weaker areas are editorial QA at 46/100, writing quality at 58/100, decision-support surfaces at 58/100, and review-content integrity at 58/100. Performance is also uneven: the supplied mobile runs recorded LCP of 3.3 seconds on the homepage, 4.0 seconds on the comparison article, and 4.2 seconds on the Czech Stella page.

The result is a capable product story with a less disciplined publishing surface.

Nonverbia is easy to place: Stella is conversation intelligence for sales teams, focused on how a message landed rather than only what was said. The FAQ names tone, attention, engagement, buyer signals, coaching, and CRM-ready follow-ups, while pricing, integrations, and comparison content make the offer concrete. The Green Marketing story adds attributable proof: Cristian Perinelli reports admin time falling from 50 to 10 minutes per call, about 90 hours returned annually, and 49 meetings analyzed. The comparison article is less disciplined, presenting 95% forecast accuracy and 267% average ROI without supplied methodology. Make the mechanism the hero promise, then place sourced proof beside it.

A prospect can answer the core questions quickly: Nonverbia is conversation intelligence for video sales calls; it analyzes calls, creates follow-ups and coaching, surfaces buyer signals, and produces CRM records. Pricing shows Free, Pro, and Business, with a 30-day trial and no credit card. The integrations page names Zoom, Google Meet, Microsoft Teams, Salesforce, HubSpot, Pipedrive, Gmail, Outlook, and Slack. The strongest mental-model bridge remains “A notetaker captures what was said. Nonverbia adds how it landed.” The remaining issue is breadth: the site addresses solo reps, small teams, 2–50-person teams, and enterprise. Lead with the primary segment before widening the story.

The public evaluation journey is direct. Pricing, Integrations, and Blog are first-level navigation targets and each is one click from the homepage. Pricing exposes Free at $0/month, Pro at $9 annual or $13 monthly, Business at $22 annual or $29 monthly, and an Enterprise custom route. Integrations groups meeting platforms, CRM systems, and communication tools. The main uncertainty sits at the conversion boundary: public CTAs send visitors to the app, while the supplied app inventory contains no crawlable links, buttons, or forms and the mobile auth capture says “Welcome back.” Use one self-serve CTA, add a clear new-user path, and explain the handoff.

Nonverbia has a strong automated accessibility baseline: PSI reports 100 for the homepage, 98 for the comparison article, and 96 for the Czech Stella page. Public pages expose header, navigation, main, footer, and section landmarks; sampled forms report no unlabeled inputs. The verified gaps are specific. The Czech page fails a foreground/background contrast audit, the comparison article has a non-sequential heading structure, and representative public pages have no detected skip link. Fix the contrast pairs, repair heading levels, and add a first-focusable “Skip to main content” link. This remains an automated review, not assistive-technology certification.

The visual system is recognizable and the 390px samples contain no horizontal overflow; homepage CLS is 0.021 on mobile and 0 on desktop. Execution is held back by mechanical scale issues. The mobile audit reports 34 small targets on the homepage and 31 on /stella; the header control is 40×40px and the logo link is 188×32px. Body text, controls, and the homepage h1 are 15px, leaving the h1/body ratio at 1.0. The CSS inventory also reports 22 font sizes and 17 radii. Raise hit areas to 44px, establish a distinct responsive h1 and 16px body baseline, then consolidate tokens.

Mobile performance is the material constraint. Lab LCP is 3,301 ms on the homepage, 4,005 ms on the comparison article, and 4,190 ms on the Czech Stella page, above the 2.5-second target. Desktop CrUX is healthy at roughly 1.44–1.47 seconds LCP, 56–60 ms INP, and zero CLS. The mobile critical path includes 252–253 KiB estimated unused JavaScript, 495 KiB of Google Tag Manager, and 224 KiB of PostHog; article and Stella TTI reaches 7,853 and 8,622 ms. Defer third-party work, split route bundles, and trace the actual LCP node before changing server architecture.

Nonverbia’s strongest copy names a useful distinction: the transcript is not the product; the product is how the call landed. The FAQ makes that tangible with engagement, attention, buying signals, deal risks, buyer-readiness, and next steps. The weak point is precision without visible sourcing. The sales-call-video-analysis article presents figures about sales interactions, close rates, time saved, and pipeline accuracy without named sources or measurement definitions. Commercial pages are also dense: pricing contains 932 extracted words with 40.4-word average sentences, while integrations averages 41.8 words. Add primary citations, define the measurements, shorten blocks, and replace generic integration promises with named workflow outcomes.

Nonverbia gives buyers real comparison material: a four-plan pricing page with visible prices and limits, plus a five-product comparison covering capabilities, pricing, and best-fit audiences. The weakness is interpretation. The pricing grid is feature-dense, and the Business column is marked Most Popular without supplied audience-specific reasoning or a visible tradeoff. The competitor table uses labels such as “Unique,” “Best,” and “Best for,” but the supplied evidence does not show a dated method or sources. Put the highest-value decision axes first, add Best for and tradeoff lines to each plan, explain shared minutes and billing, and disclose the comparison method.

The comparison surfaces are useful, but recommendation confidence is limited by provenance. The pricing page presents transparent plan choices and a Most Popular marker, while the competitor article compares five products across nonverbal analysis, transcription accuracy, coaching, deal intelligence, free tier, starting price, and best-for. The supplied evidence does not include a disclosed methodology or source for those judgments. That gap matters most where the copy uses strong labels or exact performance figures. Define each comparison axis, date the review, cite primary sources, state meaningful unknowns, and make plan recommendations scenario-based rather than implied by visual emphasis alone.

The supplied crawl confirms no traffic-suppressing defect: public pages return 200, use index/follow directives and self-canonicals, and have raw/rendered parity; the nonexistent probe returns 404 and HTTP and www consolidate to the apex in one hop. The remaining risks are operational opportunities, not evidence of a decline. The crawl flags 51 missing-alt images on the homepage and several localized titles from 66 to 73 characters. Sampled cache states are EXPIRED or MISS, with policy-page TTFB of 884 ms and 1,528 ms. GSC is not connected, so connect it before attributing any symptom to an update, deployment, or cache policy.

The public corpus is competent, but the long-form sample is not ready for unattended publication. The comparison article presents high-precision figures about sales interactions, close rates, and forecast accuracy without visible named sources or measurement definitions. It also contains the mechanical heading “Why Video Analysis Matters for Sales Success #” and opens with a broad promise before stating a bounded thesis. The crawl reports 51 homepage images without alt text, adding a second repeatable QA issue. Hold high-precision claims until they have primary citations, remove heading artifacts, check hierarchy, add descriptive alt text, and require a concrete ending in the pre-publish checklist.

The public marketing surface is in good technical shape across the 38-page crawl. Robots.txt allows crawling and declares the sitemap; sampled public URLs return 200 with self-canonicals and index/follow directives. The nonexistent probe returns a real 404, and HTTP and www requests consolidate to https://nonverbia.com/ in one 301 hop. Raw and rendered content match; the homepage is 1,756 words in both views. The actionable work is incremental: add alt text to the 51 flagged homepage and localized images, shorten localized titles measuring 66–73 characters, and investigate MISS or EXPIRED cache states. Keep authentication routes noindex and outside the sitemap.

Nonverbia earns 72/100 because its category, audience, and product differentiation are clear, while the public site covers the main questions a sales prospect is likely to ask. The accessibility baseline is strong, and the marketing surface is crawlable, server-rendered, HTTPS-consolidated, sitemap-linked, and supported by explicit robots allowance.

The fixable weaknesses are concentrated in execution. Editorial QA is the lowest public score at 46/100; writing quality, decision-support surfaces, and review-content integrity each score 58/100. The pricing grid presents features as a dump, and the supplied mobile performance runs show LCP from 3.3 to 4.2 seconds.

Nonverbia fits sales reps and small-to-mid-sized teams seeking conversation intelligence, while larger organizations can evaluate the enterprise tier. The next gains come from tighter content QA, clearer decision support, and faster mobile pages.

This is a 12-dimension review based on a crawl of 38 pages completed on 2026-10-12, plus the supplied public dimension score table and its one-line summaries. The review considers positioning, messaging, usability, accessibility, design, performance, writing, decision support, content integrity, risk and stability, editorial QA, and technical SEO as represented in the public inputs.

Google Search Console was not connected and access was unavailable, so no Search Console enrichment is represented here. The crawl visibly showed the plan prices; the separate site-facts pricing model and price range fields were unknown.
