Real-time UTM validator, GA4 campaign builder, link redirect tracer, and campaign URL audit tool powered by ValidateURL.com.

#### Short Description UTM validator and builder for GA4. Flags broken campaign links as you browse, fixes them in one click, and builds clean UTM links. #### Detailed Description ValidateURL is a free UTM validator and UTM builder for Google Analytics 4 (GA4). It checks the campaign tracking links you open while you browse, shows what is wrong, fixes it in one click, and builds clean UTM links from the page you are on. No account needed. WHAT IT CATCHES - A missing utm_source - A missing utm_medium or utm_campaign (shown as a recommendation, not an error) - Uppercase letters that split one campaign into several rows in GA4 - Spaces in UTM values - A # placed before the UTM tags, which stops them from reaching your analytics The toolbar icon shows a red (!) badge for errors and an amber (!) badge for recommendations. Pages without UTM tags show nothing. FEATURES - UTM Builder: starts from the current tab's URL, keeps the page's own parameters, and can lowercase everything automatically. - Presets: one click for Google Ads (google / cpc), Meta Ads (facebook / paid_social), LinkedIn (linkedin / paid_social), and Email (newsletter / email). - Quick Validator: paste any campaign link and see every issue in plain language. - Auto-Fix: lowercases UTM tags, replaces spaces, moves a misplaced #, and removes invisible characters. Other parameters and ad macros such as {keyword} are left untouched. - Social Share Preview: shows the title, description, and image the current page uses when it is shared. - Right-click shortcuts: send any link or page to the UTM validator, redirect tracer, UTM builder, or QR code validator on ValidateURL.com.
