UTM builder

No need to build a link for every ad. Switch to “Tags for Google Ads”, pick the campaign type (Search or Performance Max), copy the line and paste it in Google Ads → Campaign settings → Campaign URL options: into “Final URL suffix” or, if you use them, “Tracking template” – one of the two. Google fills in the campaign ID, keyword, ad or asset group itself.

Source (utm_source), medium (utm_medium) and campaign (utm_campaign). The rest is optional: a keyword for search ads, an ad variant for A/B tests, an ID for importing costs into GA4.

In Google Analytics 4: Reports → Acquisition → Traffic acquisition, with the dimensions “Session source / medium” and “Session campaign”.

No. Tags on links inside your own site start a new session and overwrite the real source. Use them only on links from outside: ads, newsletters, social media, partners.

No, as long as the page has a canonical without parameters – then search engines don’t treat such addresses as duplicates. You can check the canonical in our site audit.
