コアアーキテクチャ & 計算式
Final URL = Base URL + ?utm_source + &utm_medium + &utm_campaign
The query string begins with a question mark. Subsequent UTM parameters are concatenated using ampersands. The source, medium, and campaign fields are strictly required for accurate GA4 tracking.
ベストプラクティスとガイドライン
- Enforce Strict Lowercase Rules: Google Analytics is case sensitive. If you use 'Email' in one link and 'email' in another, GA4 splits them into two entirely different traffic sources.
- Use Standardized Mediums: Always map your medium to GA4 default channel groupings. Use 'cpc' for paid search, 'social' for organic social media, and 'email' for newsletters.
- Replace Spaces with Underscores: Never use raw spaces in UTM parameters, as browsers will convert them to ugly `%20` encodings. Use underscores or hyphens to separate words.
よくある質問 (FAQ)
Do UTM parameters affect my SEO rankings?
No. Search engines generally ignore UTM parameters when crawling. However, you should use canonical tags on your destination pages to ensure search engines don't index the UTM version as duplicate content.
What is utm_term used for?
The `utm_term` parameter is traditionally used in paid search (Google Ads) to identify the specific target keyword that triggered the ad click.
Can I hide UTM parameters from the user?
No. UTM parameters must be visible in the browser's address bar for the analytics script to read them. If you want a cleaner look, use a URL shortener that redirects to the full UTM link.
