Why consistent UTM tagging matters
UTM parameters are how analytics tools tell which campaign, channel and creative actually drove a visit or sale. The catch is consistency: Email and email become two separate sources and split your reports. Decide on lowercase, underscore-separated conventions, build every campaign link the same way, and your attribution stays clean. Keep UTMs off internal links and canonical pages.
Frequently asked questions
What is a UTM parameter?
UTM parameters are tags you add to a URL (utm_source, utm_medium, utm_campaign, and optionally utm_term and utm_content) so analytics tools can attribute traffic and conversions to the exact campaign, channel and creative that drove them.
What do source, medium and campaign mean?
utm_source is where the traffic comes from (e.g. newsletter, google), utm_medium is the channel type (e.g. email, cpc, social), and utm_campaign is the specific campaign name (e.g. spring_sale). Those three are the essentials.
Should UTM values be lowercase?
Yes — keep them lowercase and consistent. Analytics tools treat Email and email as different values, which fragments your reports. Pick a convention and stick to it.
Do UTM tags hurt SEO?
Use UTM links for ads, email and social — not for internal links between your own pages, and ideally not for links you expect others to share, since query parameters can fragment analytics and, rarely, create duplicate URLs. For canonical pages, link without UTMs.
Is this tool free and private?
