## Overview

The URL Query Analyzer is a development tool that batch parses URL query parameters to provide insights into key frequency, value samples, and detects encoding anomalies. It helps developers, SEO specialists, and marketers analyze and debug URLs efficiently by processing multiple inputs at once.

## Inputs

- **URLs to Analyze** (textarea): Enter URLs (one per line): https://example.com/page?utm_source=google&utm_medium=cpc&campaign=spring https://example.com/product?id=123&ref=affiliate
- **Extract Parameter Keys** (checkbox)
- **Extract Parameter Values** (checkbox)
- **Detect Encoding Issues** (checkbox)
- **Calculate Aggregate Statistics** (checkbox)

## When to use

- When auditing website URLs for SEO parameters like UTM tags to ensure tracking consistency.
- When debugging web applications to identify encoding issues in query strings that cause parsing errors.
- When analyzing marketing campaign URLs to track parameter usage frequency and spot anomalies.

## How it works

- Input a list of URLs into the text area, one per line.
- The tool parses each URL to extract query parameters based on enabled options like key extraction and value sampling.
- It calculates aggregate statistics, such as key frequency, and detects encoding issues like malformed percent-encoding.
- Outputs a structured JSON report with detailed analysis results for review.

## Use cases

- SEO professionals auditing website URLs to verify consistent UTM parameter usage across campaigns.
- Web developers debugging API endpoints that rely on query parameters for filtering or pagination.
- Marketers analyzing campaign URLs to ensure proper tracking and identify encoding errors that affect analytics.

## Frequently asked questions

### What types of URLs can I analyze?

Any valid URL with query parameters, including those with UTM tags, session IDs, or custom filters.

### How does encoding detection work?

It checks for common issues like unencoded special characters (e.g., spaces or ampersands) and malformed percent-encoding in query strings.

### Can I analyze URLs from a file?

No, you need to paste URLs directly into the text area; file upload is not supported in this tool.

### What statistics are provided in the output?

The output includes key frequency counts, sample values for each parameter, and flags for any detected encoding anomalies.

### Is there a limit to the number of URLs I can analyze?

The tool can handle multiple URLs, but performance may vary with very large batches; it's optimized for typical use cases.
