Webpage Quality Analyzer

High-performance webpage quality analyzer with 115 comprehensive metrics. Analyze web pages for SEO, content quality, technical standards, accessibility, and more - all in milliseconds.

🚀 Features

115 Comprehensive Metrics (92 HTML-based + 23 network-based) across 7 major categories (Content, SEO, Technical, Accessibility, and more)
8 Built-in Profiles optimized for different page types (news, blog, product, portfolio, etc.)
Multi-Platform Support: Native Rust, WebAssembly (browser/Node.js), C++ FFI
High Performance: 100+ pages/second batch processing with parallel analysis
Advanced Customization: Metric weights, thresholds, penalties, bonuses, and field selectors
Profile-Aware Scoring: Phase 3-6 implementation with category-based weighted scoring
Output Optimization: Field selection with up to 98.8% size reduction

📦 Installation

Add this to your Cargo.toml:

[dependencies]
webpage_quality_analyzer = "1.0"

Or use cargo:

cargo add webpage_quality_analyzer

🎯 Quick Start

Level 1: Simple Usage

use webpage_quality_analyzer::{analyze, analyze_with_profile};

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    // Analyze with default settings
    let report = analyze("https://example.com", None).await?;
    
    println!("Score: {}/100", report.score);
    println!("Quality: {}", report.verdict);
    println!("Word Count: {}", report.metrics.content_metrics.word_count);
    
    // Analyze with specific profile
    let news_report = analyze_with_profile(
        "https://example.com",
        None,
        "news"
    ).await?;
    
    Ok(())
}

Level 2: Builder Pattern

use webpage_quality_analyzer::Analyzer;

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    // Build custom analyzer
    let analyzer = Analyzer::builder()
        .with_profile_name("blog")?
        .with_metric_weight("word_count", 1.5)?
        .disable_metric("grammar_score")?
        .with_timeout_secs(30)?
        .build()?;
    
    let report = analyzer.run("https://example.com", None).await?;
    println!("Custom analysis score: {}", report.score);
    
    Ok(())
}

Level 3: Advanced Configuration

use webpage_quality_analyzer::{from_config_file, analyze_batch_high_performance};

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    // Load from YAML/JSON/TOML config file
    let analyzer = from_config_file("config.yaml")?;
    let report = analyzer.run("https://example.com", None).await?;
    
    // High-performance batch processing
    let urls = vec![
        "https://site1.com",
        "https://site2.com",
        "https://site3.com",
    ];
    
    let json_results = analyze_batch_high_performance(
        &urls,
        None,        // HTML (None = fetch from URLs)
        50,          // Max concurrent requests
        Some("news") // Profile name
    ).await?;
    
    for report in reports {
        println!("{}: {}/100", report.url, report.score);
    }
    
    Ok(())
}

Analyzing HTML Directly

let html = r#"
    <!DOCTYPE html>
    <html lang="en">
    <head>
        <title>Sample Page</title>
        <meta name="description" content="A sample page">
    </head>
    <body>
        <h1>Welcome</h1>
        <p>This is a test page with some content.</p>
    </body>
    </html>
"#;

let report = analyze("https://example.com", Some(html.to_string())).await?;
println!("HTML analysis score: {}", report.score);

Single page (with network): ~300-500ms
Batch processing: 180+ pages/second (HTML-only), 50+ pages/second (with network)
Memory: Linear scaling, stable across repeated analyses
Thread-safe: Fully concurrent with Arc<Semaphore> control

Output Optimization:

Full report: 30-50 KB (pretty), 12-18 KB (compact)
Minimal output: 500 bytes (98.8% reduction)
Custom fields: 300 bytes (3 fields)

// High-performance batch processing
use webpage_quality_analyzer::analyze_batch_high_performance;

let urls = vec![/* ... 100 URLs ... */];
let json_results = analyze_batch_high_performance(
    &urls,
    None,        // Fetch HTML from URLs
    50,          // Max 50 concurrent requests
    Some("news") // Profile
