The technical quality of a website is not an aesthetic opinion.

This page is the technical report for corriere.it (category Publishing & Media). It separates perceived identity (design, brand fame) from the raw technical data measured with Google PageSpeed Insights and from source-code analysis: the same parameters, in the same order, as the Audit 360° tool.

Summary: what works and what doesn't

Assessment generated from the values measured on corriere.it in the latest test: every item has a verifiable reference threshold.

✅ Strengths

No parameter meets the reference thresholds yet.

⚠️ Priorities for action

  • A 6.49 MB page: above 2 MB you pay in load time and CO₂ emissions.
  • Hosting not verified as "green": with a certified provider emissions would drop by about 89%.

Overall Assessment

Performance Analysis

Based on the simulations run, the technical architecture of the site stays below the acceptability threshold: the site works but loses visits on every load.

Dive into the technical performance analysis
Performance sits in a middle band that feels acceptable but is not: Core Web Vitals fail on at least one axis and mobile suffers. There is concrete room for recovery and, within weeks, the score can climb above 80. Discipline on assets, correct caching and attention to render-blocking components are what closes the gap.

It is worth remembering that low performance is not isolated: it severely affects real SEO ranking, increases the cost per click (CPC) of Google Ads campaigns, and depresses conversion rate.

Semantics for Artificial Intelligence

On the semantic and structured-data side (essential for LLMs like ChatGPT, Gemini and Claude), the domain is not readable by LLMs: no semantic structure for ChatGPT, Gemini and Perplexity.

Dive into the semantic and Knowledge Graph analysis
A score near zero means generative models cannot extract entities or cite the brand in answers. In a world where AI is becoming the primary access point to information, this is a huge competitive risk. A systemic intervention is needed: structured data, authoritative content, coherent ontology.

The detected Knowledge Graph infrastructure is classified as: Fragmented, with a Schema.org markup status of VALIDO.

Improvement Plan

Six concrete actions for each metric, in order of impact. Metrics in the critical band should be tackled first.

🎯 Performance Insufficient

  1. Enable Brotli/Gzip compression for HTML, CSS and JS.
  2. Convert all images to WebP or AVIF and set explicit dimensions.
  3. Move rendering of non-critical components to the server (SSR/SSG).
  4. Reduce HTTP requests: bundle CSS and JS, use sprites where it makes sense.
  5. Confirm the hosting copes with traffic: slow shared CPUs mean high TTFB.
  6. Monitor real Core Web Vitals via CrUX or in-house RUM, not just synthetic tests.

🌱 Sustainability (CO₂) Out of Standard

  1. Cut total page weight below 1 MB: every 100 KB saved translates into CO₂.
  2. Move to hosting powered by certified renewable energy (Green Web Foundation).
  3. Remove autoplay video, heavy carousels and unneeded high-resolution images.
  4. Enable compression and caching across all static assets.
  5. Reduce HTTP requests: bundling and CSS sprites where sensible.
  6. Set a carbon budget for the site and review it quarterly.

🔍 Semantic Markup Excellent

  1. Keep a register of published entities to avoid duplication.
  2. Extend the schema with advanced properties and explicit relations.
  3. Integrate data with Wikidata to strengthen recognition.
  4. Document the ontological model for the editorial team.
  5. Regularly test the graph with the Schema Markup Validator.
  6. Consider exposing the graph as static JSON-LD (faster to parse).

🧠 AI Readiness Out of Standard

  1. Publish an explicit corporate knowledge graph (entities + relations).
  2. Add authoritative pages on who you are, services and case studies.
  3. Structure content in Q&A blocks: LLMs prefer explicit questions.
  4. Use complete structured data on every page (Organization, WebSite, FAQPage).
  5. Cite authoritative sources: LLMs reward verifiable content.
  6. Monitor brand mentions on ChatGPT/Perplexity to measure progress.

The Alternative: WAA Enterprise Framework

While most traditional CMSs (WordPress, Magento, etc.) suffer from severe architectural bottlenecks that cost organic visibility, advanced JAMStack frameworks like IM Web (WAA) systematically guarantee near-100/100 performance, near-zero CO₂ emissions and native readiness (Semantic Graph) to feed Artificial Intelligence databases.
