Cometly vs Looker Studio in 2026: Pipeline-to-ARR Attribution vs Free Google-Native Reporting
One connects paid ad spend to closed-won revenue for B2B SaaS, sold only through a sales call. The other is a free dashboard builder that visualizes whatever data you connect to it, including Cometly's own exports.
Cometly
Looker Studio- Looker Studio is completely free with no usage caps. Cometly discloses no pricing publicly and bills on website session volume after a sales call.
- Cometly tracks AI referral traffic by name (ChatGPT, Gemini, Grok, Google AI Overviews) as attribution channels tied to pipeline and closed-won ARR. Looker Studio has no equivalent traffic-source detection of its own; it only visualizes whatever a connector feeds it.
- Cometly connects a specific ad click to a CRM deal value through first-party, server-side tracking. Looker Studio has no tracking or attribution layer at all; it is a reporting canvas, not a data collection tool.
- Looker Studio has a native connector marketplace of 800+ data sources, including a first-party Google Ads, GA4, and BigQuery connector. Cometly integrates with 70+ tools focused on ad platforms and CRMs relevant to B2B attribution.
- Cometly's MCP integration for Claude and CRM/warehouse sync are locked to its Enterprise tier. Looker Studio has an API on its free tier that agencies use to template client reports programmatically.
- Looker Studio support is community-only on the free tier. Cometly does not publish support tiers but requires a sales conversation to even get pricing.
Cometly and Looker Studio rarely compete for the same budget line because they are not solving the same problem. Cometly is an attribution engine: it tracks a paid ad click all the way to a closed-won deal in your CRM and bills on usage after a sales call. Looker Studio is a free visualization layer that connects to GA4, Search Console, Google Ads, BigQuery, and 800+ other sources, then lets you build and share dashboards without writing a check. Some teams run both, using Looker Studio to visualize the data Cometly captures. This comparison is for anyone deciding whether they need Cometly's attribution depth, Looker Studio's free reporting flexibility, or both.
The tools at a glance
Cometly
B2B SaaS ad attribution that connects every campaign dollar to pipeline created and closed-won ARR
Cometly exists to answer one question for B2B SaaS marketing teams: did this specific ad campaign eventually turn into revenue. It tracks the full journey from first ad impression through booked demo, deal created, and closed-won ARR, calculating LTV ROAS against actual CRM deal values rather than platform-reported conversion events. The 90-day cohort view is built for the long sales cycles that make last-click attribution misleading.
A server-side Conversion API works alongside the standard pixel, recovering roughly 15 to 30 percent more conversion events than pixel tracking alone by sending events directly to ad platform APIs. Cometly also auto-detects traffic from ChatGPT, Gemini, Grok, and Google AI Overviews and attributes pipeline and closed-won ARR to those channels the same way it does for Google Ads or LinkedIn Ads.
None of this comes with a published price. Every quote requires a sales call, billing is based on website session volume, and the newer AI and infrastructure layer, MCP integration for Claude, CRM and warehouse sync with Snowflake and BigQuery, and the Cometly API, only ships on the Enterprise tier.

Looker Studio
Free Google-native reporting tool for building interactive dashboards connected to Search Console, GA4, Ads, and 800+ other data sources
Looker Studio is Google's free, browser-based report builder. Connect a data source, drag fields onto a canvas, and publish a shareable dashboard that updates as the underlying data changes. Its native connectors to GA4, Google Ads, Search Console, Sheets, and BigQuery require no API credentials beyond a normal Google login, which makes it the fastest path from raw Google-ecosystem data to a presentable report.
The partner connector marketplace extends coverage past Google's own products to over 800 third-party sources, including CRMs and various marketing tools, though quality varies since some connectors are community-built and lag behind API changes. Reports support interactive filters and date pickers so viewers can slice data themselves, and sharing follows standard Google Drive permissions, from view-only links to public embeds.
What Looker Studio does not do is collect data. It has no pixel, no server-side tracking, and no attribution model of its own; it visualizes whatever a connector hands it. Performance also degrades on large datasets or heavy calculated fields, and support on the free tier is community-forum only, with no ticketed help.

Considering AI visibility monitoring alongside Cometly or Looker Studio?
Cometly detects when a visitor arrived from ChatGPT, Gemini, Grok, or Google AI Overviews and attributes the resulting pipeline, but it only tells you that traffic came from an AI engine, not what that engine is actually saying about your brand when nobody clicks through. Looker Studio has no AI traffic detection or brand monitoring capability at all; it is purely a visualization layer for whatever data you feed it. AI Peekaboo tracks brand mentions across ChatGPT, Gemini, Perplexity, Google AI Overviews, and Google AI Mode at the prompt level, with a read and write API on every plan from $50 a month, so agencies can pipe that data straight into a Looker Studio dashboard if they want a free reporting front end.

CometlyLooker StudioLooker StudioCometlyCometlyLooker StudioThese two are not really substitutes for one another. Cometly is a specialist attribution engine that answers whether a specific campaign became revenue, sold at enterprise-style pricing with a sales call gate. Looker Studio is a free visualization canvas with no data collection of its own, built to make whatever data you already have presentable. A B2B SaaS team with real ad spend and a long sales cycle likely needs Cometly for the attribution math, and could still use Looker Studio for free to visualize the output alongside GA4 and Search Console data.
Bottom line
Book the Cometly demo and bring your monthly session volume if you cannot currently connect a specific campaign to a closed-won deal 60 to 90 days later. Start building in Looker Studio today, at no cost, if you need to visualize GA4, Search Console, or Google Ads data for stakeholders and do not yet have an attribution problem to solve. The two are complementary rather than competing: nothing stops a team from exporting Cometly data into a Looker Studio dashboard for distribution.
Frequently asked questions
Is Looker Studio a replacement for Cometly's attribution?
No, Looker Studio has no tracking pixel, server-side conversion tracking, or CRM revenue attribution model of its own. It only visualizes data handed to it by a connector. Cometly is the tool that actually calculates which campaign produced a closed-won deal; Looker Studio could display that output but cannot generate it.
Why would a team use both Cometly and Looker Studio together?
Cometly calculates pipeline and closed-won ARR attribution against CRM deal values, while Looker Studio is free and can pull that exported data into a dashboard alongside GA4, Search Console, and Google Ads metrics for a single stakeholder-facing view. Teams that already pay for Cometly's attribution engine often still use Looker Studio as the free presentation layer.
Does Cometly track traffic from AI tools like ChatGPT the way some analytics tools now do?
Yes. Cometly automatically identifies and attributes traffic from ChatGPT, Gemini, Grok, and Google AI Overviews, applying the same pipeline and closed-won ARR metrics used for Google Ads or LinkedIn Ads. Looker Studio has no equivalent detection built in; it would only show AI referral traffic if a connected source, like GA4, already labels it that way.
Is Looker Studio really free, or does it have hidden costs at scale?
The core product is free with no usage limits on reports or data sources. Looker Studio Pro adds team workspaces and an SLA for organizations that need it, but pricing for Pro is not public and typically requires an existing Google Cloud or Workspace relationship. Most users never need to upgrade past the free tier.
Which tool makes more sense for a small B2B SaaS company just getting started with attribution?
Looker Studio is the lower-risk starting point since it costs nothing and connects natively to GA4 and Google Ads. Cometly is worth evaluating once a team has enough paid spend and CRM deal volume to justify a sales call and usage-based billing, since its value is in tying a specific ad click to a specific closed-won deal 60 to 90 days later, something Looker Studio cannot calculate on its own.
