An Uncensored Peek Inside Grammarly’s $2.2M Display Strategy

We live in a very judgmental society, especially when it comes to proper grammar and spelling. Many people are quick to assume that someone is incompetent or lazy if they spot a grammar or spelling mistake.

We hate these people.

There is even a derogatory term for them:

“Grammar Nazis”

The fact of the matter is that poor writing and grammar is an epidemic. The vast majority of our population has atrocious grammar. Even highly intelligent people may use “your” when they should have used “you’re.” You see it all the time, and it doesn’t seem like things are getting any better.

However, there is one company that is attempting to cure the poor grammar epidemic.


Grammarly was founded in 2009 by Alex Shevchenko and Max Lytvyn. Grammarly is a freemium “writing enhancement” tool. It offers a free Chrome extension and desktop app that corrects as you write. It works just like Microsoft Word’s spelling and grammar checker. However, Grammarly says its software can find up to 10 times more errors than Microsoft Word.

Grammar might be boring, but Grammarly’s growth is not.

Grammarly says it has over 3 million registered users, 50 employees, and partnerships with over 600 universities.

Display advertising has helped fuel this growth.

Today we’re going to look at how Grammarly spends millions on display to help drive subscriber growth. Grammarly has a very sound display strategy that encompasses standard banner ads, native ads, and even pre-roll video ads. If you’re at all interested in seeing a very sound display strategy, you’ll definitely want to keep reading.

Ad Spend

Grammarly has spent an estimated $2,274,816 on display over the past six months.

They have allocated the majority of their ad spending on Google Display and Taboola.


Ad Creatives

Grammarly is A/B testing creatives on both standard and native display networks.


Grammarly is testing these banner ads on the Google Display Network:


You’ll notice that Grammarly uses a lot of social proof and testimonials in their ad creatives. Some of their ad creatives are just one big testimonial and a call to action.

Quick quiz:

Which of these ads do you think is Grammarly’s current control (most-used ad):


Both of these creatives are similar.

The only difference is a slight change in the copy.

“99% of Students Get Better Grades Using This Grammar App


“99% of Students Surveyed Report Getting Better Grades With This Writing App

Which one do you think is the “winner?”

As of the publication date of this post, Ad B is the current control. You’ll see Adbeat Trend data beneath each ad below:


Why might creative B be working better than creative A?

Here are possible two reasons:

  • The phrase “…surveyed report” adds authority. It gives context behind the “99%” number, even if it does not mention the specifics behind the survey.
  • Even more subtle (but equally important) is changing “Grammar App” to “Writing App.

Think about this:

What image pops into your mind when you hear the word “grammar?”

You probably think of high school English. And if you’re like me, you probably paid little attention to grammar. Grammar is boring. Therefore, the word “grammar” has a negative connotation to it. Conversely, the word “writing” has a nice connotation to it.

Writing is creative, fun, and cool. Grammar is dry, boring, and evil.

Therefore “writing app” sounds more appealing than “grammar app.”

More Native Ads

Here are a few more native ads that Grammarly is testing on Taboola:


BONUS: Video Ads

Note: the following data was taken from the freshly launched pre-roll video ads feature now available for certain Adbeat subscribers. Read more about it here: Lights, Camera, Action: Pre-Roll Video Ads Now Available)

Grammarly also runs massive amounts of pre-roll ads on YouTube.

It is currently running three different videos targeted at three different audiences.

The first audience is students. The following video ran in the months leading up to final exams:

This video was seen on the following channels (the number on the right is how many times the video was seen on that specific channel by the Adbeat Crawler):


You’ll notice that these channels are related to topics that a college student might be interested in. This includes tutorial videos, science and math videos, TED talks, and other educational channels. For example, CrashCourse is a channel that offers various tutorials on topics like physics, history, math, and more.

The second is for job hunters. Grammarly is touted as the perfect app to spell-check your resume and cover letter or fix typos in business reports:

Here are the channels this ad was seen on:


You’ll see that these channels are a bit more general. They are targeted at a different audience, which is likely slightly older and no longer in college.

Finally there is this more general ad that covers every single situation that someone might want to use Grammarly for:

This is a relatively new video, so there is little data. However, here is a small sample of the channels where the Adbeat Crawler has seen this video:



Grammarly uses a mixture of contextual targeting (placing ads on sites directly related to the product) and demographic/psychographic targeting (placing ads on sites to target specific demographics/psychographics).


Contextually targeted publishers include:

  • Grammar-related placements on

The best example of demographic/psychographic targeting here would be Business Insider’s content has nothing to do with writing or grammar. However, Grammarly could be useful to many of its readers.

For example, Grammarly places ads on this article:


We can assume that the people reading this article are probably parents, high school students, or grad students looking at colleges. What do you need to do when you apply to college? Write essays! And what happens if your essay is full of errors? You don’t get accepted!

Landing Pages

The copy and design of Grammarly’s main landing page — its home page — is quite good.

Let’s break it down, piece by piece.


First, the headline and subheadline are quite simple.

“Your writing, at its best. Grammarly makes you a better writer by finding and correcting up to 10 times more mistakes than your word processor.”

The subheadline contains a direct benefit (it makes you a better writer).

Second, “it finds 10 times more mistakes than your word processor.” This is an important piece of copy because it adds a slight element of fear. Many people blindly trust programs like Microsoft Word to fix all of their mistakes, and now Grammarly is telling them that those programs are missing their errors.

You’ll also notice that it includes a big, red call-to-action button to add the extension to Chrome. And the first section above the fold includes a short blurb from Forbes (authority).


The middle of the landing page contains little blurbs with direct benefits. These pieces of copy cover pretty much anything that any one person could ever need when it comes to a grammar correction service.


You’ll also notice that Grammarly includes testimonials from “authority figures”:


Neither of these people are famous. Yet, the fact that one of them is a journalist and the other is a “writer” is good enough.

The next section is this simple graphic:


Grammarly has transformed a grammar app into a community. You’re not just downloading an app; you’re joining a community.

Plus, they include another big, red call-to-action at the end. Many people forget that their users will scroll down to the end and then wait to be told to do something. Tell them what to do.


There’s a lot that a display advertiser can learn from Grammarly. They have a sound strategy that includes a very good landing page and a fair amount of A/B testing of different ads, publishers, and placements.


  1. I actually converted on this just a few weeks ago from a Youtube ad. I’ve found Grammarly actually to be pretty good!

    • Yeah, pre-roll ads can work really well. Grammarly is a pretty solid piece of software!

      Thanks for reading!

  2. another Great “case study”. Getting lots of ideas , as I see the thinking behind what the Big Boys do.

    • Glad to be of help!

      Thanks for reading.

  3. They should target people learning English too.
