UTM Channel Checker

Campaign URL audit via UTM Channel Checker — utm checker that predicts GA4 Default Channel Group and Unassigned.

UTM Channel Checker helps you predict how a campaign link will land in Google Analytics 4 before you spend budget or send a blast. Paste a URL with tracking parameters, or pull the address from the tab you have open, and read a clear Default Channel Group verdict without leaving Chrome. Marketers use this when source and medium look fine in a spreadsheet yet reports fill with Unassigned, Paid Other, or the wrong social bucket after launch. Need a fast answer on a draft link? The extension parses utm_source, utm_medium, utm_campaign, utm_content, and utm_term, then maps them to GA4 Default Channel Grouping rules for manual traffic. You see which rule matched and whether weak or missing tags raise Unassigned risk. That saves a round trip through builders, docs, and trial hits in a test property. How a session works: 1. Open the campaign URL, or keep any https page ready. 2. Launch UTM Channel Checker from Chrome. 3. Review the parsed tracking fields and the predicted group. 4. Read the matched-rule note when the verdict looks surprising. 5. Copy the verdict when you need to paste it into a ticket or Slack thread. When naming conventions drift across teams, one glance at medium alone is not enough. Compare common patterns: ➤ google + cpc or ppc patterns toward Paid Search ➤ organic search and social or video source lists toward organic buckets ➤ email, affiliate, referral, display, and shopping mediums ➤ odd or empty pairs that tend to surface as Unassigned ➤ click IDs such as gclid shown among other query params The popup keeps the job tight: campaign URL field, check actions, parameter grid, group verdict, warnings, and a local-only privacy line. Other query parameters stay collapsed until you expand them, so the main read stays on source, medium, and campaign. Common problems this extension helps catch: • Campaign set without source or medium • Medium values that do not match GA4 grouping rules • Paid social links tagged like organic social by mistake • Search ads missing a paid medium pattern • Referral versus (not set) confusion on partner links • Last-minute renames that push traffic into Unassigned For deeper release checks, keep this habit nearby: 1️⃣ Test the final redirect URL, not only the ad editor preview 2️⃣ Re-check after a URL shortener or tag manager rewrite 3️⃣ Compare client naming presets against the group verdict 4️⃣ Spot-check email and affiliate templates the same way as paid search 5️⃣ Save the copied verdict next to the creative brief so QA stays shared UTM Channel Checker stays focused on inspection. It is not a URL builder first and it does not invent QR codes. If you build links elsewhere, paste them here before publish so grouping prediction and Unassigned warnings land in the same popup. Daily analytics work still benefits from short notes you can paste: predicted Default Channel Group, the matching rule, and the key source/medium pair teammates understand without opening GA4 DebugView. Privacy matters on client campaigns. Parsing stays local in the browser. The extension only reads the URL you provide or the active tab address you request. Nothing is uploaded to a server to complete a check, and nothing is sold as a side product of that read. Who benefits day to day: ▸ Performance marketers validating paid search and paid social tags ▸ SEO and content teams checking organic and referral patterns ▸ Agencies reviewing client naming before a launch ▸ Analysts explaining Unassigned spikes without guessing ▸ Anyone who inherited a link spreadsheet and needs a calm report read The product stays a dependable UTM Channel Checker for campaign URLs — clear GA4 group predictions and Unassigned warnings in the same popup. Install it, keep it in your toolbar habit, and turn every draft link into a quiet review before the report cycle starts. Limitations stay honest so expectations stay calm. The verdict is a URL-level prediction from campaign parameters against Default Channel Grouping rules for manual traffic. It does not replay a full GA4 session, does not call the Analytics API, and does not replace DebugView when you need live hit inspection. Use it to catch tagging mistakes early; confirm unusual cases in your property when stakes are high. After a successful check, keep a short internal note: predicted group, matched rule, and whether Unassigned warnings fired. That habit turns the tool into a shared QA step across creative, media, and analytics without adding another dashboard to the stack.
