How to research keywords for your ecommerce SEO strategy

 Identify your keyword universe

There are a lot of nuances between new stores and existing stores, so for the sake of brevity, I’ll assume you’re working on a brand new website.

If your store is more established, you’ll likely already have a nice baseline of data from which you can pull to help determine the direction you want to take with your research. But for a new site, you’re going to need to lean on competitor research.

The right way to do this is to find the major players in the space that aren’t colossal brands—steer clear of Amazon, eBay, Walmart, and other established, generalist ecommerce websites. Don’t be too dismissive, however, because you don’t want to necessarily stay away from the big informational brands like Wikipedia or Quora. These sites can actually be treasure troves of keyword terms and topics.

You can also start your search using an SEO tool like:

For this tutorial, we’ll use Ahrefs. Let’s say you’re an organic pet supplies brand and your main competitor is Only Natural Pet. You can enter its website URL into the Ahrefs search bar and pull up a list of organic keywords the brand ranks for.

You can also browse by Top Pages to see which webpages get the most traffic, and the top keyword for each URL.

Open a Google Sheet and start writing down the keywords you want to rank for. Logging each keyword is how you begin to build your keyword universe.

2. Find niche keywords to win

To compete against the 800-pound ecommerce gorillas these days, especially if you’re just getting started, you need to begin with a hyper-niche—a niche within a niche, and sometimes even a niche in that niche (it’s niches all the way down).

Highlighting the importance of specialization, let’s run through the entire keyword research process from start to finish with a real example. Examining something tangible is a good way to make the concepts we’ll cover easier to understand and apply.

Continuing with the pet supplies example above, let’s look at how we can find the right keywords to rank your store for.

Our first step is going to Google and doing some basic searching, starting with good old common sense. All we’re looking to do right now is see what Google comes back with from auto-suggest. For this search, I typed in “dog food,” just to kick things off.

Next, let’s see what all the Google suggestion keywords look like. To do this, we can use a keyword research tool called Ahrefs. Let’s start by entering our main keyword, “dog food,” and looking at the potential keyword ideas.

Immediately we see that supplies (containers) and type of food (raw, fresh, homemade) are common terms used to specify what these searchers are looking for. Not all of these terms are going to be relevant though. We’ll want to scan the terms and look for modifiers that we can remove using the “Exclude” keywords function.

For example, I’m noticing that some searches have brand modifiers like Royal Canin and Purina. We want to add as many of those to our negative keywords list as possible to further clean up the results. It’s OK if you don’t get every branded term in. You’ll see we included 60 of the top brands in the space. The goal is to get your list down to something more manageable.

This leaves us with 342,384 unique keywords, so from here you want to sort by monthly search volume to get a sense of how popular these keywords are.

Before going any further, let’s look at what each of these columns means in terms of the metrics they’re showing.

  • Keyword: the actual phrase that is being typed into Google.
  • Keyword difficulty (KD): an estimation of how hard it is to rank in the top 10 organic search results for a keyword on a 100-point scale
  • Volume: the average monthly number of searches for a keyword over the latest known 12 months of data (specifically targets users in the US).
  • Global volume (GV): global search volume shows how many times per month, on average, people search for the target keyword across all countries in the Ahrefs database.
  • Traffic potential (TP): this shows the sum of organic traffic that the #1 ranking page for your target keyword receives from all the keywords that it ranks for.
  • Cost per click (CPC): the average price advertisers pay for each ad click in paid search results for a keyword.
  • Clicks per search (CPS): the ratio of clicks to keyword search volume. It shows how many different search results get clicked, on average, when people search for the target keyword in a given country.
  • Parent topic: determines if you can rank for your target keyword while targeting a more general topic on your page instead.
  • Snippet Features (SF): the number of enriched results on a search engine results page that are not traditional organic results.
  • Updated: the date when Ahrefs last checked search engine results for a keyword.

When looking at keyword data as part of your overall research process, it’s important to recognize that the keywords you identify based on your initial run and first attempts at filtering are just the tip of the iceberg. Understanding how your users think with research like a contextual inquiry will help you identify new keywords.

Any of these terms with a search volume over, say 100 per month, is likely to have a whole universe of related terms around it. For example, let’s look at some of the related terms that come back for a few of the terms in my current list.

💡 Note: I’m using the same list of negative keywords, with a filter set to only show keywords that receive more than 100 searches per month, on just Google.com.

Topic: best dog food

Topic: dog food container

Topic: raw dog food

Topic: natural dog food

This exercise is exactly why you always pull the data and don’t make guesses when it comes to defining your content map and best keyword priorities.See more about SEO.

Looking back over the terms generated from the four keywords above as seed terms:

  1. “Best dog food” comes back with relevant suggestions including 29,494 other terms.
  2. “Dog food container” comes back with relevant suggestions including 2,164 other terms.
  3. “Raw dog food” comes back with 10,567 other keywords.
  4. “Natural dog food” includes 9,182 additional terms and makes a strong case for creating a content page targeting these keywords.

3. Create a research process

You can run through the above process around 10 to 15 times to build substantial lists of relevant terms to work with. Even easier, you can manage most of these steps right in Ahrefs.

Here’s what my list looks like, including terms throughout the shopping funnel, i.e., specific pet food terms, container sizes, calculators, and top-of-the-funnel terms like “how to” and others.

Armed with a solid list of terms to target, the question remains: Now what? Answer: It’s time to group these into topics.

4. Build a topic map

A topic map is a spreadsheet where you group related keywords together into smaller lists that all roll up under a representative topic.

For example, some of the topic maps from my data set are:

Topic: “Best dog food”

Keyword Volume
Best dog food for puppies 7,600
Best dog food for pitbulls 4,400
Best dog food for picky eaters 2,000
How to choose the best dog food 50

 

Topic: “dog food container”

Keyword Volume
Dog food container 50lbs 2,500
Dog food metal container 1,500
Ceramic dog food container 500
Dog food container with wheels 400
How to keep ants out of dog food container 40

In both of the examples above, I’m taking general swings at grouping together the keywords from my list into topics. But this isn’t the end of our research process. From here, it’s important to determine if these groupings make sense based on content type.

Google has shown time and time again that it prefers to rank specific kinds of content for specific queries. If you want to rank for a particular term or a set of terms, you need to build out the type of content that Google is showing you it wants to see.

The most common types of content are:

  • Informational pages (think Wikipedia)
  • Product catalog pages (Category, Sub-Category, Product Detail)
  • Blog posts (even these can vary in form, but for the purposes of this post I’m going to lump them all together)
  • Video
  • Reviews
  • Visual/infographics
  • Audio/podcasts

5. Map the different content types

It’s helpful to deliberately plan the types of content you need to create to best target your keywords. The most straightforward way to do this is through some old-fashioned Googling. Create a spreadsheet for yourself using the exported lists of keywords from Ahrefs as a starting point.

Within that sheet, you can create a new tab with the following columns:

  • Keyword
  • Topic
  • Volume
  • Difficulty
  • Content Type

The two highlighted rows above will need to be entered manually. Admittedly, this is going to be a bit tedious, but it’s worth the effort! Here’s an example of mapping the different types of content for my dog food container example.

This one is a great example of a mixed search engine results page.

It looks like the easiest path to break onto this SERP is to invest content and link resources into ranking a product category page. Second easiest is a list-form article. However, if you’re selling direct on Amazon, you’re going to need to amass a few thousand reviews.

We can immediately see the results skew toward pages with high commercial intent. There’s the product listing ads (PLA) carousel at the very top (before the text ads), and then we’re greeted with a variety of product category pages.

Now that you’ve gone through your priority terms and mapped all the content types, it’s time to create a plan for how to build out this content. A smart first step is designing a deliberate “content map.” This asset outlines your requirements (your ideal keywords), your blueprint (what content needs to be produced), and your structures (a roadmap for content production).

6. Develop a content calendar

You have your priority keyword list in hand, you know what types of content you need to create, and you’ve mapped these across your site.

Now it’s time to build a calendar so you can put rubber to road and start getting this content live and ranking for your target keywords. To do this, it’s helpful to create additional sheets in my overall keyword file and lay them out by funnel stage (based on search intent).

You’ll also want to bring together all of the other components of this process:

  • Topic focus
  • Content type
  • Test title 1
  • Test title 2
  • Test title 3
  • Target keyword
  • Additional keywords
  • Target length
  • URL

Here’s an active example, including all of the parameters above.

Then, build a sheet specifically for the schedule with the following columns:

  • Draft completed by date [ACTUAL]
  • Publish date [ACTUAL]
  • Draft needed by date [ESTIMATED]
  • Expected publish date [ESTIMATED]
  • Author
  • Status [Not started, Assigned, In progress, Pending, Published]
  • Blog post type [If post, Category of Post]
  • Post topic and description
  • Example site
  • Recommended URL
  • Recommended title
  • Recommended H1
  • Recommended meta description
  • Target keywords
  • Notes

You can then bring in your content creation and management resources into this sheet and filter each of these columns to get visibility into your ecommerce SEO efforts from a content and keywords perspective.
