Referrer basics
- The concept: The address of the web page the visitor was on just before arriving on your site
- His role: Identify your digital business drivers (Google, Facebook, a partner blog...)
- Utility: Measure the effectiveness of your investments in each channel
- The limit: If a visitor types your address directly, there's no referrer ("Direct Traffic")
In the real world, if a new customer comes into your store, you often ask them: "How did you hear about us?". On the Internet, it's the Referrer (or referent) who answers this question for you.
For an executive or a marketing manager, the referrer is the digital trace that allows you to go back to the source. It's how you know whether your LinkedIn advertising budget is more effective than your latest blog post.
How does the "fingerprint trail" work?
Every time a user clicks on a link to your site, their browser sends the starting URL. This data fills your dashboards:
- Referrer = google.com : Your efforts in SEO or SEA pay
- Referrer = linkedin.com : Your social strategy is on track
- Referrer = site-partenaire.fr : Your alliance is profitable
Why is it the compass of your marketing budget?
What the referrer reveals
- Hidden opportunities (new sites talking about you)
- Effectiveness of your banners
- ROI for each channel
- Profitable partnerships
Limits to be aware of
- Direct traffic (no referrer)
- HTTPS to HTTP switchover (mask)
- Dark Social messaging
- Mobile applications
Advice : Use UTM parameters on your links to accurately track each campaign, even when the natural referrer gets lost (newsletters, QR codes, WhatsApp...).
