In a nutshell

Walmart gets 250M+ monthly traffic via SEO! Of course, they ace many areas in marketing. But, their SEO strategy powers $43B in online sales. Let's learn about it!

Their SEO strategy emerged from a crisis.
You see, in any online store, items are organised into different categories.
Categories -> Sub-categories -> Products

Now a category can have many different products
For example:
- Category = Computers
- Sub-category = Computer Accessories
- Then, Product = Keyboard, camera, mice, etc

But if you optimise product pages for keywords like 'camera', 'keyboard', 'mouse', etc.
Then every page will rank for the same keyword, which will result in them competing with each other.
For a website like Walmart that has millions of product pages, this is a huge problem.

So, to solve this problem, Walmart uses the taxonomy principle!
Taxonomy is simply classifying items in a structured way.
It is an SEO technique used to organise pages into categories with help of tags.

Now, Walmarts pages are organized in the structure:
Domain -> Walmart .com
Department -> Electronics
Category -> Computers
Sub-category -> Laptop

Each stage in this structure has a unique URL structure & every page is also optimized for a unique keyword! With this strategy, Walmart gets 252 million monthly organic traffic! So, its an absolute success :)

Whether it operates in your country or not, you've heard of Walmart — it's simply that famous.

Walmart is world's largest company by revenue ($559B USD), and they've established themselves as a retail giant. In recent years, Walmart has successfully taken that fame online.

To make it big in the online world, well, you need to get in Google's good books. Even when you're as big and popular as Walmart, SEO isn't something you can ignore.

Of course, to keep up with the times, they've adopted many amazing SEO strategies. I've picked one of Walmart's strategies to tackle today — read on!

What was the issue that needed solving?

When it comes to retail, items are split into categories. Categories are further divided into sub-categories. The sub-category then has a list of products.

So, Categories → Sub-categories → Products.

While this means that you have an extensive product catalog, it could be disastrous, SEO-wise.

Let's break this down:

  1. You have a product 'A', under sub-category 'Y', under category 'X' (X → Y → A)
  2. But, A is not the only product you have under this sub-category. There could be any number of products here:
    • Suppose you're an electronic store and your category is Computers. A sub-category under this is Computer Accessories.
    • Then, you would have keyboards, mice, cameras and other accessories under this sub-category.
  3. If you now optimise the product pages for the keyword 'Computer Accessories', every page will rank for the same keyword.
    • They would in turn end up competing against each other on Google.

For Walmart, a gigantic store, the negative impact of doing this is multiplied exponentially. Millions of product pages would compete against each other and end up driving away users.

Got it, but is there a solution to this?

Are you familiar with the term 'taxonomy'? It means classifying things in a structured fashion. Eukaryota, Animalia till Homo sapiens in Science, for example, where each word gives more specific details than the previous.

Taxonomy is also an SEO technique, where pages on the websites are made based on the structure of the content. Categories, tags and other such divisions impart this structure.

If there's a good SEO taxonomy strategy in place, the content is clear to search engines. As a result, visitors are led to very specific pages on the website depending on their search query.

Okay, but what did Walmart do with this knowledge?

Every product page on Walmart is created using a parent-child structure — a perfect example of a great taxonomy.

Page structure

The main site,, has over 50 million pages - we'll call our domain.

There are two kingdoms in this domain, our main categories:

  1. Departments — for everything you can buy, like a shoe.
  2. Services — for services you can utilise, like those of an auto care center.

There are Departments such as Grocery, Electronics, Toys & Video Games and others. The case with Services is similar, they are split into types.

These Departments are further divided into Categories.

Under the department Electronics, we have the categories TV & Video, Tablets & Accessories, and Computers, among others.

Still not done — Walmart further divides these Categories into more focused sub-categories. You'll find laptops, PC Gaming, desktops under the category Computers.

Now, if I click on Laptops, I end up on a landing page which shows me a collection of laptops.

Finally, clicking on any one laptop takes you to a dedicated landing page for that product.

So far, we've traversed:

The domain, → the department, Electronics → the category, Computers → the sub-category, Laptops → the product.

Here, each term to the left of the arrow is the 'parent' of the term to the right — the 'child'. Also, each page is optimised for a different keyword.

Deep navigation in some departments would show even broader pathways to get to the product page.

You must be saying, "Wow. That's a really neat navigation & structure!"

URL structure

Following the page structure Walmart has used, the URL should have been:[product-name].

But, as a rule of thumb in SEO, URLs should be short — and Walmart wasn't losing out on anything.

The URL of the Laptop page we arrived at above is

While it's still big, the case is such because of the product name and not any unnecessary extension Walmart has applied to the URL.

This is a common pattern followed across product page URLs -[product-name]

Walmart also has lading pages for the category and sub-categories. These have 'cp' instead of 'ip' — '' and '', for example.

Amazing! But did it help Walmart?

Thanks to a detailed taxonomy strategy, it is easier for Walmart to target relevant keywords. Users are directed to very specific landing pages — no two pages are optimised for the exact same keyword.

No kidding here, Walmart's SEO stats speak for themselves. According to Ahrefs, they get a monthly organic traffic of 252 million!

Combined with Walmart's other SEO & marketing efforts, the taxonomy strategy acts as a major booster to their sales. In 2021 itself, Walmart reached $43B USD in online sales, a more than 70% increase year-over-year!

How Glassdoor dominates backlinks through data-driven content

Simply put, Glassdoor offers 'data-driven content'. Let me explain.
It is a:
1) Job posting portal — employers can post & advertise open jobs
2) Job review portal — employees can share feedback about their company

On Glassdoor's website users share about everything from bosses & salaries to work culture & the hiring process. This data is then organized by the platform across different parameters.

Glassdoor uses the data to create:
1) Lists of top founders, companies, etc
2) Surveys presenting employee choices
3) Reports about trends & employee preferences

Data-driven content is shared extensively.
A couple years ago we published a report titled 'State of Remote Work'. People loved the insights that were included and shared it.
This report generated backlinks from 141 unique domains.

The Glassdoor website is full of data-driven content.
For example, they recently published the Workplace trends for 2022. This has insights around economic recovery after Covid-19, for instance. The information can be used by employees, newspapers and politicians.
So, the content is bound to be shared. When that happens, it generates backlinks.
This Glassdoor article has 360 backlinks in just over 2 months.

With so many high authority website backlinks, Glassdoor's domain authority is bound to go up. Glassdoor's DR is as high as 91, so they always rank at the top. Competitors would be lucky to beat Glassdoor!

1) Use data-driven content to get attention and links.
2) Website authority is key! It takes time & effort to buildd authority, but it's a huge boost to rank any content on your website higher on Google.
