Frequently asked questions

What are UTM parameters?

Tags added to the end of a link, such as ?utm_source=facebook&utm_medium=cpc&utm_campaign=summer_sale. When someone arrives through that link, Google Analytics records which platform, channel and campaign sent them.

Where do I see the results?

In Google Analytics 4, open Reports › Acquisition › Traffic acquisition and set the primary dimension to Session source / medium or Session campaign to compare traffic and conversions.

Which UTM parameters are required?

Always fill in utm_source (e.g. instagram), utm_medium (e.g. social) and utm_campaign (e.g. mid_autumn_2026). utm_term and utm_content are optional, for keywords or ad variations within one campaign.

Should UTM values be upper or lower case?

Lower case, with underscores instead of spaces. GA4 treats Facebook and facebook as two different sources and splits your reports; this tool offers to tidy them.

My UTM link is too long. Can I shorten it?

Yes. Press Shorten and track clicks to turn it into a lnk.hk short link for WhatsApp, Instagram bios or print. The short link also counts clicks, referrers and countries, which you can compare with GA4.

Do UTM parameters hurt SEO?

Use them only on links you share (ads, emails, social posts), not on your site’s internal links. With a canonical tag on your pages, UTM-tagged URLs don’t affect rankings.
