Overall Score
A3 Mercados is a technically competent financial market infrastructure site with solid structure and impressive live market data integration, but it's strangled by sluggish performance, accessibility oversights, and a mobile experience that feels like watching paint dry through a small window.
The Roast
This site is like a Bloomberg terminal's overly serious Argentine cousin—all data, no charm. It's got the technical chops of a proper fintech player, but the performance metrics suggest it's running on the same servers that power your local bank's 1997 dial-up system. The mobile experience is particularly savage: 31 out of 34 images are flying blind without alt text, which is less 'progressive enhancement' and more 'accessibility violation speedrun.' The good news? It's fast enough to trade, slow enough to make you regret it.

Accessibility
188 ARIA attributes suggest the dev team *tried*, but missing alt text on 31/34 images is a catastrophic failure. No skip link, and while landmarks exist, the excessive ARIA without proper semantic HTML is likely cargo-cult accessibility.
Issues Found
- 91% of images lack alt text (31 missing out of 34); includes critical product/feature images (Warrants, PPT, pricing charts). Screen reader users get nothing.
- No skip-to-main-content link; users with keyboard navigation must tab through entire nav and ticker bar to reach content—violates WCAG 2.1 AA
- 188 ARIA attributes without clear semantic HTML suggests over-reliance on ARIA. If nav is a `<div>` instead of `<nav>`, or buttons are `<span role='button'>`, the accessibility is illusory
Recommendations
-
Add alt text to all images immediately high
Audit all 34 images; write descriptive alt text for feature images (e.g., 'Warrants: Registro y negociación con respaldo documental'), data chart alt text should describe trends/values, not just 'chart'.
-
Add skip-to-main-content link high
Insert a visually hidden link at the start of the page that jumps keyboard users directly to the main content area, bypassing nav and ticker bar.
-
Audit ARIA and replace with semantic HTML medium
Review all ARIA attributes; replace divs with semantic tags (nav, main, article, button) where possible. ARIA should enhance, not replace semantics.
Conversion
Primary CTA ('Conocé A3 Mercados') appears once in hero and leads to a generic page; secondary CTAs ('Ver más' on product cards, 'Ingresar' on quotations) are weak and lack urgency or clarity. Conversion funnel is undefined.
Issues Found
- Single hero CTA is non-specific; 'Conocé A3 Mercados' doesn't clarify if user is signing up, opening an account, or just learning. No sense of urgency or benefit.
- 'Ver más' links on product cards (Warrants, PPT, panel 3) are passive; no indication of what 'más' includes or why user should click
- 'Ingresar' on quotation cards (panel 2) is ambiguous—does it mean 'open an account', 'view details', or 'enter an order'? No micro-copy or visual emphasis.
Recommendations
-
Create primary and secondary CTA hierarchy high
Hero CTA: 'Abre tu Cuenta de Trading' (outcome-driven). Secondary: 'Ver Futuros Disponibles' and 'Explorar Opciones' to segment by product interest.
-
Add micro-copy to secondary CTAs medium
Pair 'Ver más' with a benefit hint: 'Ver más → Especificaciones, Horarios de Negociación' so users know what they'll gain from clicking.
-
Implement post-CTA friction reduction high
Ensure 'Abre tu Cuenta' CTA links to a streamlined signup form (3–5 fields) or broker partner hub, not a generic landing page. Measure conversion rate.
Mobile
Mobile layout exists but feels like a desktop layout squished into a 375px viewport. Text is small, spacing is tight, and interactive elements (buttons, links, carousel) are cramped. Ticker bar is unreadable, and nav degrades to a flat link dump.
Issues Found
- Live ticker bar (panel 4) displays 4–5 instruments in a single line with tiny font; not readable and not touch-friendly. Users can't see relevant data without horizontal scrolling.
- Hero CTA button ('Conocé A3 Mercados', panel 4) is small (~120px wide) and hard to tap; no clear visual distinction from surrounding text.
- Data tables below hero (panel 4) are unreadable at 375px; column headers and cells are squashed. No horizontal scroll affordance or collapsible columns.
Recommendations
-
Redesign mobile ticker as carousel or summary high
Show only 2–3 most important instruments per screen, with larger font and swipe affordance. Or collapse ticker to a single summary ('Mercados: Estables' / 'Fuerte Alza') and link to full data.
-
Increase touch target size for CTAs and buttons high
Ensure all buttons and links are at least 44×44px (WCAG 2.1 AAA), with adequate padding. Hero CTA should span full width or be at least 48px tall.
-
Implement responsive table component high
Use a stacked card layout or horizontally scrollable table with clear overflow affordance on mobile. Hide non-essential columns (e.g., 'Ajuste', 'Interés Abierto') on small screens.
Performance
Mobile PageSpeed of 72 is mediocre; LCP at 2.9s is above ideal (under 2.5s), INP at 141ms borders on poor (under 100ms is good). The unused JavaScript warning is a red flag—bloat without benefit.
Issues Found
- LCP (Largest Contentful Paint) at 2.944s indicates slow time-to-first-meaningful-paint; hero image or text is rendering slowly. Likely culprit: unoptimized hero background or render-blocking JS
- INP (Interaction to Next Paint) at 141ms suggests janky responsiveness; users will notice lag when interacting with ticker carousel, dropdowns, or form inputs
- Unused JavaScript warning + TTFB at 513ms point to either: unoptimized JS bundles, heavy third-party scripts (tracking, ads, market data feeds), or server-side performance issues
Recommendations
-
Audit and defer non-critical JavaScript high
Identify unused JS bundles (likely from build tooling or unused features) and defer or lazy-load them; prioritize critical path JS (navigation, ticker updates).
-
Optimize hero image and lazy-load below-fold images high
Compress hero background, use modern formats (WebP), and add lazy-loading for data tables and product cards below the fold.
-
Implement edge caching and optimize server response medium
Reduce TTFB by caching static assets (CSS, JS, fonts) at the edge (CDN) and optimizing server-side rendering for dynamic pricing data.
Trust Signals
Schema markup for organization (name, phone, address, taxID) is solid, and multiple contact methods are displayed (phone, email, physical addresses in Rosario & Buenos Aires). Social links present (Instagram, LinkedIn, X), but no testimonials, case studies, security badges, or regulatory compliance markers visible.
Issues Found
- No visible trust badges, security certifications, or regulatory compliance markers (e.g., 'Operadora de Mercados Regulada por CNV'). Critical for a financial services site.
- No testimonials, case studies, or client logos (not verified from screenshots, but typically expected for B2B fintech).
- Footer (panel 3) includes compliance/legal links ('Normativa CNV', 'Reglamentos', 'Circulares', 'Documentos operativos') but no prominent trust statement or 'Why Trust A3' section on homepage.
Recommendations
-
Add regulatory compliance badges above fold high
Display CNV (Comisión Nacional de Valores) logo or a statement like 'Operadora Autorizada de Mercados - Matrícula CNV Nro. 13' prominently on hero or footer.
-
Create a 'Why Trust A3' trust section medium
Add 3–4 trust markers below hero: decades in operation, regulatory oversight, institutional backing, 24/5 support. Use icons and short copy.
-
Showcase client logos or testimonials (if available) medium
If A3 has institutional clients, brokers, or satisfied traders, display logos or short quotes below the 'Productos destacados' section to build credibility.
Design & UX
Clean, professional B2B aesthetic with solid hierarchy and a cohesive navy-blue color palette—but the layout feels more corporate memo than modern fintech. Desktop experience is organized; mobile collapses into a narrow, dense list of links that begs for better information scent.
Issues Found
- Mobile navigation (top panel 5) degrades to flat link lists under 'Sobre A3', 'Normativa', 'Info de mercado', 'Contacto'—zero visual differentiation, scannability nightmare
- Hero section hero on mobile (panels 4-5) drops all supporting context, leaving only headline + button; no value prop visible below fold for most users
- Live ticker bar (panel 1) is crammed with 8+ instrument tickers in tiny font—readable on desktop but illegible on mobile, defeating the purpose
Recommendations
-
Restructure mobile nav hierarchy high
Replace flat link lists with card-based navigation sections on mobile, or use collapsible accordion groups with icons to reduce cognitive load and improve scannability.
-
Optimize live ticker for mobile medium
Reduce ticker items displayed on mobile to 2–3 most relevant instruments, or swap to a horizontal carousel with larger font and better touch targets.
-
Enhance mobile hero messaging medium
Ensure key value prop (e.g., 'Mercados de futuros y opciones para Argentina') is visible above the fold on mobile without scrolling.
Copy & Messaging
Headline is punchy ('Creamos mercados para el desarrollo del país'), but supporting copy is vague corporate-speak that assumes the reader already knows what A3 does. CTAs are present but weak; 'Conocé A3 Mercados' is passive and uninspiring.
Issues Found
- Hero subheading ('Integramos productos, tecnología e infraestructura...') is buried below CTA and uses jargon; doesn't clearly state *who should care* or *why*
- CTA copy is action-averse ('Conocé' = informal 'learn about'); should be outcome-driven (e.g., 'Accede a Futuros y Opciones' or 'Comienza a Operar')
- Below-the-fold section headings ('Datos de Mercado', 'Cotizaciones') are descriptive, not persuasive; no narrative connecting features to user benefit
Recommendations
-
Rewrite hero CTA high
Change from 'Conocé A3 Mercados' to an outcome-driven action like 'Accede al Mercado de Futuros' or 'Abre tu Cuenta Hoy' to clarify next steps.
-
Add a secondary headline medium
Insert a 1-sentence secondary headline below the primary that explains the specific benefit (e.g., 'Operar futuros y opciones con transparencia y seguridad'), not just features.
-
Humanize feature descriptions low
Pair data table headings ('Cotizaciones') with benefit statements (e.g., 'Precios en tiempo real para decisiones más inteligentes').
SEO
Strong schema markup (Organization + FinancialService + WebSite with SearchAction) and proper meta tags, but the actual content is thin (1,175 words) and lacks keyword diversity. H1 exists but H2–H3 structure is repetitive and doesn't build semantic depth.
Issues Found
- Content is primarily navigation labels and data tables; only ~300 words of actual keyword-rich body copy. Thin pages = weak organic ranking potential
- 18 H3s but no clear topical clustering; H3s are generic section labels ('Posición', 'Compra', 'Venta') rather than semantic content blocks
- Missing schema for Financial Product, Trading Instrument, or Quotation—only generic Organization/FinancialService. Site deals in structured data (prices, tickers) but doesn't markup the products themselves
Recommendations
-
Expand home page body content high
Add 500–800 words of keyword-rich copy explaining products (futures, options, warrants, PPT), market data features, and use cases for traders, brokers, and institutions.
-
Implement Product + Quotation schema medium
Markup each traded instrument (SOJ.ROS/SEP26, etc.) with schema.org/FinancialProduct and BrokerageAccount types, and add Quotation schema for live prices.
-
Restructure H2–H3 hierarchy medium
Replace data-table labels with semantic H2 headings ('Futuros Agropecuarios', 'Futuros Financieros', 'Cotizaciones del Día') and use H3 only for secondary topics under each.
