> Free UTM builder for paid-ads campaign URLs. Live preview, one-click copy, lowercase enforcement, source / medium presets, and a local-storage recent-URL history. Built for media buyers running Google, Meta, ChatGPT, and other paid channels.

## What it does

Build clean campaign URLs with the standard five UTM parameters:
- `utm_source` — google, meta, chatgpt, etc. (with presets dropdown)
- `utm_medium` — cpc, paid-social, email, etc. (with presets dropdown)
- `utm_campaign` — campaign identifier
- `utm_term` — paid keyword (optional)
- `utm_content` — creative ID (optional)

Required fields: destination URL, source, medium, campaign. Copy button stays disabled until all required fields are filled.

## Features

- Live URL preview that updates as you type
- One-click copy with toast confirmation
- Lowercase + space-to-underscore enforcement (toggle)
- Datalist presets for source (google, meta, facebook, instagram, linkedin, tiktok, youtube, chatgpt, newsletter)
- Datalist presets for medium (cpc, paid-social, display, email, affiliate, organic, referral, video)
- Recent URL history saved to browser localStorage (last 8, clearable)

## Why it exists

Every analytics team eventually wishes there had been a UTM naming convention from day one. Retrofitting UTMs after the fact is painful. This tool enforces the convention before the URL is built.

## ChatGPT Ads specifically

Per OpenAI's documentation, ChatGPT Ads supports static tracking parameters on landing-page URLs — they persist through ad clicks. Recommended UTM stack for ChatGPT campaigns:
- `utm_source=chatgpt`
- `utm_medium=cpc` (for Clicks objective) or `cpm` (for Reach objective)
- `utm_campaign={campaign_name}`
- `utm_content={ad_group_or_hint_name}`
- `utm_term={keyword_theme}` if relevant
