Browser-side link QA
Paste links into the URL and UTM Checker
The URL and UTM Checker parses each line locally, then recommends a cleaner URL and canonical slug without crawling the page or using a database.
Your pasted links stay in this browser tab. The URL and UTM Checker does not fetch external pages, upload URLs or store campaign data.

How the URL and UTM Checker reviews every link
The URL and UTM Checker focuses on browser-verifiable link details: URL structure, slug shape, UTM fields, query parameters, encoding and copy-ready cleanup.
URL and UTM Checker structure parsing
Paste full URLs, bare domains, relative paths or page slugs. The URL and UTM Checker extracts the base domain, path, slug, query string and campaign parameters without fetching the destination page.
URL and UTM Checker issue report
The URL and UTM Checker flags duplicate parameters, empty values, spaces, unencoded characters, mixed UTM case, malformed joins, long links and privacy-risk values such as email, phone, token and user ID fields.
URL and UTM Checker cleanup workflow
Use the URL and UTM Checker before newsletter sends, paid ads, social posts, ecommerce campaigns or SEO publishing. Copy the cleaned link, then keep your source URL and analytics reports easier to trust.
URL and UTM Checker features for Web and SEO teams
Use the URL and UTM Checker as a practical preflight for independent stores, newsletters, ad teams, creators, social media operators and SEO publishers.
Slug recommendations
The URL and UTM Checker turns spaces, uppercase words and messy page slugs into a cleaner lowercase hyphenated slug suggestion.
UTM completeness
The URL and UTM Checker shows whether utm_source, utm_medium and utm_campaign are present, then helps you review optional utm_term and utm_content values.
Parameter cleanup
The URL and UTM Checker finds duplicate names, empty values, spaces, mixed case and bad separator patterns that can split analytics data.
Privacy-risk review
The URL and UTM Checker flags query parameters that look like email addresses, phone numbers, tokens, sessions or user identifiers before public sharing.
Copy-ready clean URLs
The URL and UTM Checker lets you copy one cleaned link or all cleaned links after duplicate, empty and privacy-risk parameters are removed from the recommendation.
How to use the URL and UTM Checker before publishing
The URL and UTM Checker is built for fast pre-publish review. It checks the pasted string itself, so private drafts and staging pages do not need to be crawled.
01
Paste links into the URL and UTM Checker
Paste one URL per line. You can mix full URLs, domains, relative paths and page slugs, which is useful when campaign links come from spreadsheets, ad builders, CMS fields or newsletter tools.
- One link or slug per line
- No page fetching or database lookup is required
02
Review the URL and UTM Checker warnings
Start with Fix items such as privacy-risk query data, then review missing UTM fields, duplicate parameters, empty values, unencoded characters, spaces, mixed case and long URLs.
These are practical browser-side checks. Your analytics platform may still apply its own attribution rules, normalization and reporting filters.
Review report 03
Copy the URL and UTM Checker clean link
Use the recommended clean URL when it matches your campaign intent. Recheck the final version after edits so the link you publish is the link you meant to track.
Keep a source-of-truth naming convention for UTM values so paid ads, newsletters, creators and social posts report consistently.

Answers about privacy, accepted inputs, UTM accuracy, slug recommendations, clean links and URL and UTM Checker result interpretation.
What does the URL and UTM Checker validate?
The URL and UTM Checker validates pasted URLs, domains, relative paths and slugs for parseability, path and slug format, UTM completeness, duplicate parameters, empty values, spaces, non-ASCII characters, malformed separators, length and privacy-risk query data.
Does the URL and UTM Checker crawl my link?
No. The URL and UTM Checker only parses the text you paste in the browser. It does not fetch the destination page, follow redirects, call a database or upload your campaign links.
Can the URL and UTM Checker guarantee analytics attribution?
No. The URL and UTM Checker confirms that required UTM fields are present and highlights common formatting problems, but analytics platforms can still normalize values, ignore parameters or apply their own attribution rules.
Why does the URL and UTM Checker flag privacy-risk parameters?
Public links can accidentally expose emails, phone numbers, tokens, session IDs or user IDs in query strings. The URL and UTM Checker flags values that look risky so you can remove them before publishing.
What happens to page slugs in the URL and UTM Checker?
A bare slug or relative path is treated as a local page path. The URL and UTM Checker recommends a lowercase, hyphenated canonical slug and keeps the output relative instead of inventing a real domain.
Should I always use the URL and UTM Checker clean URL?
Use the clean URL when it matches your campaign plan. The recommendation removes duplicate, empty and privacy-risk parameters, normalizes UTM casing and encodes unsafe characters, but you should keep any intentional business parameters your destination needs.
Run the URL and UTM Checker before links go live
Paste the final campaign links, fix risky parameters and copy clean URLs before ads, newsletters, social posts or SEO pages are published.
The URL and UTM Checker is a practical browser-side QA tool, not an official analytics, ad platform or search engine validator.
