Analytics for agencies that clients actually open

Seline is the simple, privacy-first analytics tool for agencies. Run every client site from one workspace, share live dashboards instead of PDF reports, and tie campaigns back to real revenue.

Agency analytics built for client work, not GA4 certification courses

Seline is the analytics tool we wish we had when we ran client work. Every property lives in one workspace, every dashboard is a shareable URL, and every number is easy to explain on a client call. No tag manager work and no weekly screenshot exports.

“Previously, I had all of my sites hooked up to Google Analytics, like most people. But I never looked at the reports. Now, I find myself dropping in and looking at the stats several times a day. It's very easy to digest and understand.”

Why agencies keep moving off Google Analytics

We talk to dozens of agencies a month. The complaints are almost always the same, and they all hit the renewal conversation, not just the dashboard.
1
GA4 is unreadable for clients.
Most clients open GA4 once, get lost between "explore" and "reports", and never come back. You end up screenshotting numbers into a monthly slide deck. With Seline they bookmark one live URL and reporting stays up to date.
2
Cookie banners hurt client conversion.
Low consent rates leave GA data incomplete. Seline is cookie-less and GDPR-ready, so the banner can come off and your client typically sees more traffic in reports.
3
Pageviews do not prove ROI.
Sessions and bounce rate rarely justify a renewal on their own. Seline ties UTMs and referrers to actual revenue events, so you can walk into the renewal call with a concrete dollar figure attached to your work.
4
Multi-site setup is painful.
Sharing access to twenty GA4 properties across a large team is hard to manage. In Seline, every client site lives in one account with role-based access for your team. Per-site pricing is available if you need it.
5
Reporting is a manual job no one wants.
Rebuilding monthly reports in Looker Studio takes hours each month. Share a live Seline link instead and spend that time on client work.

How Seline solves agency analytics

Seline keeps a Google Analytics-style tracking surface (pages, sources, devices, locations) and stacks the tools an agency actually needs on top: shareable views, visitor journeys, conversion funnels, and revenue attribution. All under one workspace, all real-time.

Four ways agencies use Seline day to day

Different agencies use Seline differently. SEO teams care about source attribution, paid teams care about UTM-to-revenue, product studios care about visitor journeys.

These are the patterns we see most often when an agency rolls Seline out across a client portfolio.

Monthly reporting with live links

Send a shared Seline link instead of rebuilding slide decks each month. Your client gets a live view of every metric you both care about.

Proving paid-channel ROI

Map UTM parameters to revenue and show, in dollars, what every Google Ads or LinkedIn Ads campaign is bringing in. Renewal conversations focus on revenue and return, not impressions alone.

Pinpointing landing-page leaks

Build a funnel from ad click to landing page to form submit for every campaign. The client sees where users drop off in real time, so you can agree on what to fix next.

Defending SEO work with journeys

When a client says SEO is not converting, open a visitor journey: organic search to blog post to pricing to contact-us. The path is visible in one place, which makes it easier to plan the next quarter of work.

What you get on every client site

Shareable client dashboards

Send each client a read-only link to their live dashboard. No accounts to create, no GA4 access requests, and no PDF exports that are out of date when the client opens them.

One workspace, many sites

Run every client property from a single Seline account. Switch sites in one click and scope permissions per teammate. Per-site pricing is available if you need it.

Revenue attribution by channel

Connect Stripe or send custom revenue events to tie every UTM, referrer, and campaign back to dollars. Show clients which work drove revenue, not just traffic.

Easy to integrate

Drop a 2kb script on any client site. Works with Webflow, Framer, WordPress, Shopify, Next.js, plain HTML, and everything in between.

Lightweight

Our script weighs ~2kb, roughly 23x smaller than the Google Analytics tag. Your client sites stay fast and their Core Web Vitals scores stay clean.

GDPR-ready by default

EU-based, hosted in Germany, cookie-less by default. No consent banner, with a DPA ready when a client asks for one.

Privacy-friendly

No third-party cookies, no cross-site tracking, no selling of client data. A privacy promise you can include in client proposals.

Google Analytics alternative

A privacy-first GA alternative your clients can actually read. Real-time numbers, clear labels, no training required.

Custom events

Track contact form submits, demo bookings, downloads, button clicks, or anything else that counts as a conversion for that specific client.

Agency analytics Q&A

The best analytics tool for an agency is one your clients actually open. Seline gives every client a clean dashboard with sources, pages, journeys, funnels, and revenue, without GA4's report builder or a learning curve. One workspace covers your full portfolio under a single bill.

Yes. A single Seline account holds all of your client sites. You switch between them in one click and scope permissions per teammate. Per-site pricing is available if you need it. Most agencies onboard their full portfolio in a single afternoon.

Every Seline dashboard has a public share link. Send it in your monthly report email or embed it inside a Notion or Coda client portal. Your client opens the URL and sees live numbers for their site, with no Seline account needed.

No. Seline is cookie-less, does not track visitors across sites, and stores data inside the EU. Most jurisdictions do not require a consent banner with this setup, but you should still confirm details with your client's legal team.

Yes. Connect Stripe or send revenue events so every campaign, page, and channel ties back to real money. Use that in client reviews and renewals to show revenue from your work, not just traffic reports.

Yes. Our 2kb script works on every framework and CMS we have seen. We ship one-line install guides for Webflow, Framer, WordPress, Shopify, Next.js, Astro, Remix, and plain HTML inside our docs.

GA4 pushes clients into a report builder they will never use, hurts Core Web Vitals, and forces a cookie banner. Seline is privacy-first, real-time, and simple enough for your team and clients to use day to day.

Per-site pricing is available if you need it. You manage every client from one Seline account and add sites to your workspace as the portfolio grows. See our pricing page for details.
