In a nutshell

BrowserStack is a cross-browser testing tool that can be used to test software on different browsers and applications.

Their target audience is primarily developers. They are highly technical and appreciate in-depth tech content.

Secondly, testing is frustrating. So, these devs would not go research multiple sources to find the best way to do anything in testing.

Given these 2 points, BrowserStack took a leap to create guides for its audience that are highly technical and in-depth in nature.

Their SEO strategy looks something like this:
1) Find relevant queries related to software testing and specifically their product
2) Create a detailed guide to wow tech folks, so they rave about the content and share it.
3) Optimize for SEO & hope Google ranks them.

BrowserStack uses this high technical, in-depth guides to wow their users, so they rave about them to other developers. When readers love this content and share it, eventually Google also recognized your effort!

Content is KING! And when you publish in-depth content that your readers rave about, Google absolutely LOVES it.

So, when BrowserStack, a wildly popular software testing platform, used the strategy of publishing highly technical, in-depth guides, the result was 500K+ monthly users from Google!

This article is a deep dive into BrowserStack's SEO strategy and a reminder that high-quality content is key to SEO success. Read on.

Firstly, what is this BrowserStack? And, how did they get started?

BrowserStack's success story is a tale of persistence.

It started with two IIT Bombay students with a dream to buildd their own company one day. They dappled with 2 solid ideas which failed to generate any excitement in investors.

After trying for 3+ years & not raising a single penny, these dreamers had to go back to holding their day jobs. But, they didn't give up!

While working on their third company the duo came across a problem. Both the founders absolute hated testing software. They got into an argument over who would be testing that day. But, out of that argument came a billion-dollar idea.

You see, when a developer buildds a piece of software, they have to test it on different devices, browsers and platforms, to make sure the software function properly. Before BrowserStack, this process was a complete hassle.

In fact, in 2011, when BrowserStack was still in conception, the founders found some 100 people complaining to Microsoft about how difficult it is to test their websites on Internet Explorer. This served as a validation for BrowserStack & the duo set out to buildd the world's software tester!

Today, BrowserStack is a one-stop cross-browser testing app that was bootstrapped for 7 years to $50M revenue and $40M profits!

Lesson ➝ Your startup doesn't need to fail fast. It can succeed slow.

So, how are they doing SEO-wise?

SEO so far has been the most effective marketing channel for BrowserStack. According to Similar web, ~60% of BrowserStack's traffic comes through "Search".

So, let's see how they are doing!

  1. BrowserStack gets 528,000 monthly visitors & it ranks for 192K keywords
  2. Moreover, it has a DR of 83, with 945K backlinks! 🤯
  3. Their most popular subfolder is their "guides" blog, which we will learn more about in the next section.

Great! So, what's their SEO strategy?

Now, the most direct way users could discover BrowserStack is:

i) Searching for BrowserStack's page directly

ii) Searching for cross-browser testing tools

But, only a handful of people search directly for BrowserStack (20k+) or for "cross-browser testing tools" on Google per month. So, there should be some other way to get these users.

Understanding your target audience

With any SEO strategy, the key is to accurately understand who your users are and what they want.

For BrowserStack,

  1. The target audience is primarily developers. They are highly technical and appreciate in-depth tech content.
  2. Secondly, testing is a frustrating activity for developers. So, they would not go the extra mile to research multiple sources to find the best way to do anything in testing.

Given this, BrowserStack took a leap to create highly technical, in-depth guides for their developer audience. Rather than just having simple how-tos or short blogs that address only specific queries.

Now, creating guides is no easy task. It takes a lot of time & effort and may seem counter-intuitive when your primary objective is to drive traffic via SEO.

But, BrowserStack's key goal was to appeal to a specific audience and wow them. By doing so, they hoped to get great conversions to paying users.

Lesson ➝ You don’t need millions of traffic, but only thousands of visitors converting to paying users.

BrowserStack's SEO strategy!

So, BrowserStack's approach to SEO looks something like this:

  1. Find relevant queries related to software testing and specifically their product.
  2. Create detailed guides to wow tech folks, so that they rave about the content.
  3. Of course, optimise for SEO and hope Google picks up the signals to rank them for even difficult keywords.

Sounds simple, but it's the execution that's intensive.

And, what was the result?

a) SEO traffic
b) Getting backlinks
c) Ranking for high-intent keywords with high-difficulty

What are the key takeaways for us?

So, what can we learn from BrowserStack?

Well, there are a few hidden takeaways that founders can learn through this strategy:

  1. SEO is not just about getting traffic. You should also plan for conversions and building brand & authority.
  2. Writing in-depth guides in your industry is a tedious process — requires a lot of time & effort. It will also take you time to see results, but it’s the best way to establish long-term authority in your field and be able to rank for high difficulty, high intent keywords
  3. A great SEO strategy would be to have a mix of these initiatives —

    i) Targeting low-difficulty keywords to drive traffic & see medium-term results

    ii) Targeting high intent keywords & writing in-depth content to establish long-term authority

Zapier is a simple workflow automation tool that allows you to move information between apps & connect them to create automated workflows. It gets ~2M monthly traffic & has 50k+ automated pages! It's vastly successful, thanks to its brilliant SEO strategy.

To drive traffic to their website, Zapier created two sets of pages. The blogs on "Best Apps" & the App Integration pages.

One of the top-performing Zapier subfolders is the /apps landing page. This set of pages accounts for ~15% of Zapier's total traffic with 235K monthly visitors! The idea behind creating these pages is simple. Zapier wants to target all users who are searching for ways to connect different apps.

This set of pages forms a 4 stage hierarchy, where each stage links to the next stage. The pages are, Main Page -> App Profile Page -> App-to-App Integration -> Zaps Page.

Next, the best app blogs are basically blogs that list down top apps in the market in a particular category. For example, the best URL shorteners, the best note-taking apps, the best to-do list apps, etc. These pages get 900K monthly organic traffic, ie. 60% of traffic to their site!

Zapier ranks for really difficult keywords with these pages. It does that by writing high-quality SEO optimized content, internally linking all pages to flow the authority & acquiring high-quality backlinks.

All these pages are internally linked & are created using an automated template to reduce effort while creating new pages!

Unacademy IPL Ads Spend - Was the 40 Cr ads spent worth it?

Unacademy started out as a simple college hobby for a co-founder, Gaurav Munjal. In 5 years, it was built into the actual company with a free tier and a subscription model.

Being the 2nd largest ed-tech startup in India, Unacademy enjoys a lot of attention from VCs.

Its current valuation is $3.44B, after it raised a $440M funding round in 2021. Much like any other VC-funded startup with deep pockets, Unacademy naturally spends a huge amount on growing its user base.

Given the wild popularity of IPL in India and that most of their target audience tunes in to watch IPL, Unacademy spends a ton on IPL ads.

1) Overall, in 2022, Unacademy spent Rs 40 Cr on IPL ads in 2022.

2) Their target audience accounts for over 40% of IPL’s total 20 Cr viewership, which is 8 Cr target audience.

3) Unacademy's paying user conversion rate = paying users/net users = 350K/30M *100 = 1.1%.

4) Traditionally, the TV ad conversion rate is 0.7%. So, net net the paying users = 8 Cr x 0.7% x 1% = 5600 users.

5) We finally get the customer acquisition cost (cac) = Rs 40 Cr/5600 users = Rs 72K/user

6) If we say that on average the course fee is around 10K. Unacademy still is burning ~60K per user acquired.
