Looker Studio (formerly Google Data Studio) review: Is it the right reporting tool for your agency in 2026?

What is Looker Studio? (formerly Google Data Studio)

Looker Studio is Google’s free reporting tool. It extracts data from Google and third-party data sources into interactive dashboards for performance tracking. Marketing teams use it to transform marketing data into visual reports for internal and external audiences.

Looker Studio sits inside the Google environment. If your stack leans heavily on Google Analytics, Google Ads, Google Sheets, YouTube, and Google Suite products, Looker Studio connects these data sources easily and gets reports live quickly.

Looker Studio core features

• Data connectors: Looker Studio connects to Google products natively and supports partner connectors for platforms outside the Google ecosystem, allowing for centralized reporting.

• Interactive dashboards: Users build dashboards with adjustable filters and date controls, allowing people to explore metrics dynamically rather than viewing a fixed PDF.

• Data blending: The data blending functionality joins data sources inside a report. For example, blending spend data from various ad platforms to compare performance in one view.

• Custom charts and tables: The platform offers charts, tables, scorecards, and other visualization options. Users edit layouts to build custom reports around the metrics that matter to them.

• Calculated fields: Built-in functions allow users to create custom KPIs or modify existing metrics. This helps when a single data source does not give the exact calculation that you need.

• Collaboration and sharing: Reports work like Google Docs, with user access controls, real-time editing, and the ability to share live reports via a link.

Pros of using Looker Studio

One of the main benefits of Looker Studio is that the standard version is free. This lowers the barrier to entry and allows teams to set up basic reports at no cost, which is especially convenient for small businesses or agencies.

Because it sits neatly inside of the Google suite, it also offers a familiar feel and connects easily with Google data sources that teams are already using. This makes it a user-friendly option for those already familiar with Google products. Here's what one user wrote in a G2 review:

Looker Studio makes it incredibly easy to build interactive, shareable dashboards and reports all without coding. The wide range of native connectors (Google Analytics, Google Ads, BigQuery, Sheets, etc.) and partner connectors makes it possible to combine data from multiple sources in one place.

For many teams, Looker Studio strikes the right balance between flexibility and accessibility. You don’t need a full BI stack or a data engineering team to build polished reports, but you're also able to set up a few custom KPIs and choose appropriate data visualizations. A user review on TrustRadius highlights this sentiment:

Thanks to easy integration with the Google environment, it provides a quick way to visualize data. It's very easy to use, so you don't need to be a data engineer to set up a basic dashboard.

Users often highlight that it works best as a high-level reporting tool. It offers a solid free option to create simple, straightforward reports—especially if your team is primarily pulling from Google data sources. For example, one Reddit user shared:

Looker Studio is a simpler tool for simpler business and simpler professionals. I use it a lot for small customers who have small data in a live spreadsheet and want to see it dynamically in another way.

Cons of Looker Studio

Looker Studio gives users simplicity, but as reporting grows more complex, performance issues surface, and teams start to face the product's limitations. Especially for teams that need to report on large data sets, managing more comprehensive or detailed reports gets tricky. One Reddit user shared:

I find it to be frustratingly slow. Depending on the number of fields and tables in your database it can be unwieldy to create dashboards. As the number of variables grows it can be cumbersome.

Beyond the tool being fairly limited for scale, it also has flexibility limitations. Users report that it takes significant time and manual work to set up the right level of customization needed for unique reports or specialized metrics. Here's how one user explained this in a TrustRadius review:

Google Data Studio is [...] not the best when you want to build highly specific graphs and manipulate the data exactly the way you want to. Although there are formula functions to help with this, it can be difficult and time-consuming for beginners.

Another important consideration is the platform's ability to create client-ready reports. While users are able to build reports quickly and easily, these reports aren't necessarily suitable for external use, and may not be up to snuff for agencies that need professional, branded client reports offering clear data insights. As one Reddit user put it:

It’s not meant to be pretty. It’s meant to let you get basic insights without fuss.

How Looker Studio compares to other reporting tools

Looker Studio isn't a full enterprise BI tool, nor is it a client reporting platform purpose-built for agencies. It excels for its native Google suite integrations and cost efficiency, but falls short if you need streamlined client reporting, white labeling, or multi-client automation.

Let's take a look at how Looker Studio compares to the competition feature-by-feature:

Data integrations

Looker Studio connects well with other Google products, like Google Analytics, Google Ads, Google Sheets, and YouTube. If your team is Google-heavy or needs to set up a single source dashboard using Google Search Console data, for example, it will work well for this purpose. Where it falls short is its ability to connect different data sources, because many of these are third-party integrations.

Other reporting platforms offer pre-built, plug-and-play native integrations with the same marketing tools. When platforms integrate with reporting software directly, it makes it much easier to blend, analyze, and present data clearly. One Reddit user shared their experience using first-party vs. third-party data connectors within Looker Studio:

I use it primarily for SA360, Google ads & Google Analytics reporting and it’s super easy to connect/create dashboards. It gets trickier when you need to create your own sources/connectors that aren’t native.

Dashboard customization

Reports created in Looker Studio are flexible, and users have control over layouts with multiple charts, tables, filters, and fields. Teams are able to blend data sources, create dynamic dashboards, and tailor reports with various data visualization options.

Other marketing reporting tools like AgencyAnalytics offer deeper customization, more advanced features like anomaly detection, metric alerts, and AI summaries, in addition to drag-and-drop widget elements. Here's how a Software Advice user review describes it:

You can create nifty dashboards, but [Looker Studio] is not as flexible as other commercial tools.

White labeling & branding

Looker Studio provides limited branding options. While charts, colors, and logos are customizable within a report, full white labeling, custom domains, and client portals aren’t built in. For agencies that need branded reports delivered automatically to clients, this is a gap.

In contrast, reporting tools designed for digital marketing agencies provide full white labeling, automated branded exports, and client portals that make reporting scalable and professional from day one.

Even taking a step back from custom branding, getting each report set up to suit the needs of each client isn't as easy as it seems with Looker Studio, because it's more suitable for in-house reporting with limited scale. A user review on GetApp explains this limitation well:

[C]reating custom reports can become a time-consuming process - as you try to figure out how to display the data you want, while working around some of the limitations of Google Data Studio. This includes simple things like being able to modify the title of a specific chart - in some charts, this is an easy function; while in others, it is impossible, forcing you to use a custom title.

Is Looker Studio right for your agency?

Looker Studio is a great tool for digital marketers doing simple reporting on Google data—but it lacks client-oriented advanced features that really make a difference for agencies. Let's break down some examples of when choosing Google Data Studio makes sense for an agency, and when other BI tools are a better fit:

A more capable Looker Studio alternative

AgencyAnalytics is an all-in-one platform for agency reporting and automation. Unlike Looker Studio, it isn’t a general-purpose, lightweight BI tool—it’s purpose-built around agency workflows. That means everything from multi-client management to white labeled dashboards, automated reporting, and 85+ built-in marketing integrations work out of the box.

For agencies juggling multiple clients, campaigns, and platforms, AgencyAnalytics removes the manual overhead and gives teams a faster, more polished way to deliver insights. It still offers interactive dashboards, data blending, and calculated fields, but everything is optimized for agency scale.

Key features that set AgencyAnalytics apart

• Pre-built marketing integrations: Connect to 85+ platforms, including Google Analytics, Google Ads, social media platforms, SEO tools, and CRMs. Integrations are plug-and-play—no third-party connectors to troubleshoot.

• White label dashboards and PDFs: Deliver fully branded reports and dashboards to clients, including custom logos, domains, and color schemes. Pre-built digital marketing dashboard templates make it easy to set up professional reports quickly, without manual tweaking.

• Client portals: Provide clients with secure access to live dashboards, enabling them to explore metrics interactively and stay up-to-date on performance independently.

• Automated reporting: Schedule recurring reports to be sent automatically via email or delivered to client portals. This reduces repetitive work and ensures consistency across accounts.

• Multi-client management: Manage dozens or hundreds of clients from a single interface. Easily switch between accounts and keep reporting organized and centralized.

• Built-in SEO & PPC tools: Track rankings, monitor campaigns, and see ad spend performance without additional BI setup. Plus, pre-built SEO dashboards for client reporting make it easy to use SEO analytics to inform strategy. This also sets it apart specifically as a strong SEO reporting platform for agencies.

• AI summaries and insights: Quickly surface actionable insights using AI-generated summaries of campaign performance. This saves time compared with manually interpreting raw metrics, and makes it easy to create clear digital analytics dashboards.

• Performance alerts & goal tracking: Set alerts for changes in KPIs and track goals over time, keeping clients proactively informed and campaigns on track.

• Interactive, customizable dashboards: Drag-and-drop interface lets you build dashboards quickly while customizing charts, tables, and metrics as needed. The design is optimized for client readability, not just internal analysis.

Final verdict

Looker Studio remains a solid free tool for turning Google data into clean dashboards. It connects easily to Google products, lets you blend different data sources, and create reports easily. For small teams or simple reporting needs, it works, but as reporting grows more complex, the limits show.

Managing many clients, blending large datasets from different sources, or delivering polished, branded reports with dedicated client access is better accomplished with other tools designed to meet these needs. Agencies that want a true reporting solution should opt for a platform that's purpose-built like AgencyAnalytics.
