Introduction to Grammarly Case Study
Grammarly is one of the leading writing assistant tools, helping millions of users enhance clarity, grammar, and style in their writing. From casual writers to enterprise teams, it offers a mix of AI-powered editing, tone suggestions, and workflow integration.
In today’s SaaS landscape, performance marketing and precise audience targeting are critical. Companies that combine data-driven campaigns with measurable outcomes can scale faster and more efficiently. Grammarly is a prime example of this approach, using performance marketing to drive user growth, enterprise adoption, and measurable ROI.
This case study dives into Grammarly’s marketing strategy, adoption across enterprise clients, and the business impact verified through official case studies.
Grammarly’s Growth Through Performance Marketing
1. What is Performance Marketing?
Performance marketing is all about accountability. Unlike traditional marketing, where results can be vague, performance marketing ties every campaign to specific, measurable outcomes like clicks, conversions, or sales. For SaaS companies like Grammarly, it means:
- Targeting high-intent users with precision.
- Continuously optimizing campaigns based on real data.
- Linking marketing spend directly to business impact.
2. Grammarly + Microsoft Advertising Collaboration
Grammarly worked with Microsoft Advertising to focus on the people who actually use and create content, what they call “prosumers.” It wasn’t about spreading ads everywhere. The goal was to reach the right users, in the right place, at the right time.
They used insights from LinkedIn, Outlook, and Bing to figure out where attention was highest. Not every campaign was perfect. Some needed tweaking. That’s where recurring lift studies came in. They kept track of engagement, awareness, and conversions across the funnel.
With every campaign, adjustments were made. Some messages worked better than others. Some channels performed differently. The key was staying flexible and always learning from the data. That constant feedback loop kept campaigns efficient and effective.
It’s a simple idea. Focus on your audience, measure carefully, and refine often. That’s how you make marketing actually work.

Grammarly’s Performance Marketing
Grammarly’s marketing isn’t about blasting ads everywhere. It’s precise, targeted, and backed by data. The focus is on “prosumers”, people who write, read, and create content regularly. These users care about quality, efficiency, and tools that actually help them. Grammarly’s campaigns are built around understanding what this audience wants and where they spend their time.
The partnership with Microsoft Advertising was a turning point. They implemented an audience-first, data-driven strategy that made every dollar count. Insights from LinkedIn, Outlook, and Bing helped identify where attention was high, making campaigns more effective. The results speak for themselves (Source):
- 42% lift in search activity directly from targeted campaigns.
- 73% increase in conversions, showing the audience responded.
- 33% more site visits, proving relevance and interest.
- 23% drop in cost per acquisition, demonstrating efficiency even as scale increased.
Campaigns weren’t left on autopilot. Grammarly ran recurring lift studies to measure brand awareness, engagement, and conversion rates across the funnel. Each campaign was tweaked based on real data, creating a loop of continuous improvement.
