How to Set Up Seline Analytics on a Website
Setting up Seline Analytics means adding a whisper-thin (~2kb) HTML snippet to your website — the site describes this as "no setup required," meaning the snippet alone is enough to activate the core analytics features. You can then optionally send custom events to track user behavior, and connect Seline to tools you already use. This guide covers the prerequisites, the steps, how to verify it works, and where people commonly get stuck.
What you need before you start
- Access to your website's HTML — either the source files or a tag/script manager that can inject code into every page.
- A Seline account. The site offers a free trial and a pricing page, so you can evaluate it before committing. (Check the current terms on seline.com/pricing — the input doesn't state whether the trial requires a card.)
- A decision on scope: website analytics only, or also user-centric product analytics. Seline says if you have a SaaS, you only need to identify your users to start with its user-centric product analytics — comparable to Amplitude or Mixpanel, but simpler.
Step 1: Add the tracking snippet
- In Seline, locate the HTML snippet for your site (the site describes it as ~2kb).
- Paste it into your site's HTML so it loads on every page — typically in the
<head>or just before</body>, or via your tag manager. - Save and deploy.
Expected result: Once the snippet is live, Seline begins collecting real-time data. The site states that "no setup required" means you only need to add the snippet for the feature to work — no additional configuration is needed for the core dashboard.
Step 2: Read the real-time dashboard
After the snippet is live, the all-in-one dashboard shows:
- Total Visits, Views per Visit, Visit Duration, and Bounce Rate, each with a change indicator.
- Sources — referrers such as facebook.com, reddit.com, x.com, google.com, duckduckgo.com, and bing.com.
- Referrers, countries, devices, UTM parameters, and more.
This is the "easy-to-use website analytics" layer: where visitors come from and how they interact with your site.
Step 3: Send custom events (optional)
To go beyond pageviews, send in custom events. Seline's Journeys view then shows each individual visitor and their path through your site. The site's example journey shows a single user with a signed up event carrying props (email, referral: blog), alongside page visits like /sign-up, /, /blog, and /web-analytics, each with a time-on-page and device context (Desktop, macOS).
Expected result: You can study individual journeys and see the full picture, not just aggregate traffic.
Step 4: Identify users for product analytics (SaaS)
If you run a SaaS, identify your users to unlock user-centric product analytics. Seline positions this as an Amplitude/Mixpanel-style capability that is "actually digestible, easy to use, and naturally insightful."
Step 5: Integrate with your existing tools
Seline says it integrates easily with the tools you already use, and you can run it standalone or alongside your current stack — so you don't have to rip out Google Analytics to try it.
How to verify it's working
- Open your site in a browser and check the real-time dashboard for your own visit.
- Confirm your referrer, country, and device appear.
- If you added custom events, trigger one and confirm it shows in the visitor's journey.
Common sticking points
- Snippet not on every page. The dashboard only reflects pages where the snippet loads. Use a tag manager or a shared template to avoid gaps.
- Expecting setup beyond the snippet. The site emphasizes "no setup required" — the snippet is the setup for core features. Custom events and user identification are separate, optional steps.
- Privacy assumptions. Seline is described as no cookies, no personal data collected, GDPR & CCPA compliant, and based and hosted in the EU. If your compliance review needs specifics, verify them against Seline's own documentation rather than assuming.

The site's own framing is worth noting: one quoted founder said they previously had all their sites on Google Analytics "but I never looked at the reports," and now checks Seline's stats several times a day because it's "very easy to digest and understand." If your problem is that you collect data but never read it, that's the gap Seline is designed to close.
