How to Do Keyword Research for eCommerce: Step-by-Step Guide

For an online store, getting your products in front of the right people is everything. You might have the best products and a beautiful website, but if customers can’t find you, you won’t make sales. This is where keyword research comes in. It is the foundation of a successful online business, directly impacting your store’s visibility, traffic, and ultimately, your revenue.

Think of keywords as the bridge connecting what your customers are searching for to the products you sell. By understanding and using the exact words and phrases they type into search engines, you can lead them directly to your digital doorstep. This guide provides a clear, step-by-step process for effective eCommerce keyword research. You will learn how to find the terms that your customers use, analyze their intent, and build a keyword strategy that drives growth.

What Is Keyword Research in eCommerce?

In simple terms, eCommerce keyword research is the process of finding and analyzing the search terms that people use to find products online. The goal is to identify which keywords will bring the most relevant and valuable traffic to your product pages, category pages, and blog posts. It’s about getting inside your customer’s head to understand their needs and how they express them in a search bar.

While it shares similarities with general SEO, eCommerce keyword research has a unique focus: commercial intent. General SEO might target keywords to attract readers for a blog, but SEO for online stores is laser-focused on attracting shoppers. The primary goal is to drive sales.

Effective keyword research helps you discover profitable terms that show a clear intention to buy. For example, someone searching for “running shoe reviews” is still gathering information. However, a person searching for “buy nike air zoom pegasus 39 men’s” is ready to make a purchase. Finding these high-intent keywords is crucial for an online store’s success.

Understanding Your eCommerce Audience

Before you can find the right keywords, you need to know who you’re trying to reach. A deep understanding of your audience is the first step in any strong keyword strategy for eCommerce. This means going beyond basic demographics and digging into their shopping behaviors and motivations.

Start by creating customer personas. These are fictional profiles of your ideal customers. Give them names, jobs, and interests. What are their goals? What problems are they trying to solve with your products? Understanding these details helps you think like they do.

Next, identify their search intent. Search intent is the “why” behind a search query. It generally falls into three main categories for eCommerce:

Transactional Intent: The user wants to buy something. These keywords often include terms like “buy,” “deal,” “discount,” or specific product names. For example, “buy anker power bank online.” These are high-value keywords for product and category pages.

Informational Intent: The user is looking for information. They might be comparing products, looking for solutions to a problem, or learning more about a topic. Examples include “what is the best coffee maker” or “how to clean leather boots.” These keywords are perfect for blog posts and buying guides.

Navigational Intent: The user is trying to find a specific website. They might search for “Amazon” or “Zappos login.” While you can’t target another brand’s navigational keywords, you should ensure your own brand name ranks first when people search for it.

By mapping keywords to the buyer journey—from awareness to consideration to purchase—you can create content that meets customers at every stage.

Tools for eCommerce Keyword Research

To do keyword research effectively, you need the right tools. These tools provide valuable data that helps you make informed decisions. There are both free and paid options available, each with its own strengths.

Here are some of the most popular tools for eCommerce keyword research:

• Google Keyword Planner: A free tool from Google designed for advertisers, but it’s also great for SEO. It helps you discover new keywords and provides estimates on their monthly search volume.
• Ubersuggest: A user-friendly tool that offers both free and paid versions. It provides keyword suggestions, search volume data, and insights into what your competitors are ranking for.
• Ahrefs: A comprehensive, paid SEO toolset. Its Keyword Explorer is incredibly powerful, offering precise search volume data, keyword difficulty scores, and in-depth analysis of the search results pages.
• Semrush: Another all-in-one paid SEO platform. Its Keyword Magic Tool allows you to generate millions of keyword ideas from a single seed keyword and filter them with various metrics.

When using these tools, focus on a few key metrics:

• Search Volume: The average number of times a keyword is searched for per month. Higher volume can mean more potential traffic.
• Keyword Difficulty (KD) or Competition: An estimate of how hard it will be to rank on the first page of Google for that keyword.
• Cost Per Click (CPC): The average price advertisers are paying for a click on that keyword. A high CPC often indicates strong commercial intent.
• Trends: How a keyword’s popularity has changed over time. This is useful for identifying seasonal products.

Step-by-Step eCommerce Keyword Research Process

Now that you understand the basics, let’s walk through the process of finding and selecting keywords for your online store.

Step 1 – Brainstorming Seed Keywords

Seed keywords are the starting point of your research. They are broad, foundational terms that describe your products or categories. Think about how you would describe your products to someone. Write down all the terms that come to mind.

Your seed keywords will typically come from:

• Your Products: List out your main products (e.g., “yoga mat,” “electric kettle,” “beard oil”).
• Your Categories: What groups do your products fall into? (e.g., “kitchen appliances,” “men’s grooming,” “fitness equipment”).
• Your Brand: Include your brand name and any unique product names you have.

Once you have a list, it’s time to look at your competitors. Identify your top 3-5 competitors and analyze their websites. What keywords are they using in their page titles, descriptions, and headings? Tools like Ahrefs and Semrush have features that let you enter a competitor’s domain and see the keywords they rank for. This can uncover many opportunities you might have missed.

From your initial brainstorm, you can start expanding. For example, a seed keyword like “running shoes” can be expanded into more specific terms like “best running shoes for women,” “trail running shoes for men,” or “new balance running shoes sale.”

Step 2 – Analyzing Search Intent

With a list of potential keywords, the next step is to analyze their intent. As we discussed, understanding whether a searcher is looking to learn or to buy is critical.

Here’s how to distinguish between transactional and informational keywords:

• Transactional Keywords: These signal a strong desire to make a purchase. They often include words like:
  Mini Case-Insight: An online camera store saw a 150% increase in conversion rate on its “Canon EOS R5” product page after optimizing it for transactional keywords like “buy Canon EOS R5” and “Canon R5 deals.” They realized their previous content was too informational, and shoppers were leaving to find a place to purchase.
  • Buy
  • Discount
  • Deal
  • Coupon
  • Sale
  • Shop
  • Specific product model numbers (e.g., “iPhone 15 Pro”)
  • Qualifiers like “for sale” or “cheap”
• Informational Keywords: These suggest the user is in the research phase. They often start with:
  • How to
  • What is
  • Best
  • Review
  • Comparison
  • Vs (e.g., “drip coffee vs french press”)

Prioritize high-intent transactional keywords for your product and category pages. These pages are your primary money-makers. Save the informational keywords for your blog, where you can provide value, build trust, and guide potential customers toward a purchase.

Step 3 – Using Keyword Tools Effectively

Now, take your brainstormed list and plug your seed keywords into a tool like Ahrefs, Semrush, or Ubersuggest. These tools will generate a huge list of related keywords. The sheer volume can be overwhelming, so it’s important to use filters to narrow it down.

Generate Long-Tail Keywords:
Long-tail keywords are longer, more specific phrases that shoppers use when they are closer to a point of purchase. They usually have lower search volume but a much higher conversion rate. For example, instead of targeting “shoes” (a short-tail keyword), you would target “women’s waterproof hiking boots size 8” (a long-tail keyword). Your keyword tool will help you discover thousands of these variations.

Filter and Refine Your List:
Use the tool’s filtering options to find the best opportunities. Here are some common filters to apply:

• Search Volume: Set a minimum search volume (e.g., at least 50 searches per month) to ensure there is some demand.
• Keyword Difficulty: If your site is new, focus on keywords with a low difficulty score (e.g., under 30) to have a better chance of ranking.
• Include/Exclude Terms: Filter for keywords that include transactional terms like “buy” or “sale.” You can also exclude terms that aren’t relevant, like “free” or “jobs.”

Once you have a refined list, export it as a CSV file. You can then open it in Google Sheets or Excel to organize your keywords further. Create columns for the keyword, monthly search volume, keyword difficulty, and intent (transactional or informational).

Step 4 – Categorizing Keywords for eCommerce Pages

A well-organized keyword strategy requires mapping your keywords to the right pages on your site. A messy approach where you target the same keyword on multiple pages can confuse search engines and hurt your rankings.

Create a clear structure for where each type of keyword belongs:

• Category Pages: Target broader, product-focused keywords. These pages should rank for terms that describe a group of products.
  • Example: A page for “Men’s Jackets” would target keywords like “men’s jackets,” “winter coats for men,” and “buy men’s jackets online.”
• Product Pages: Target very specific, long-tail keywords that describe an individual product. These should be highly transactional.
  • Example: A product page for a specific North Face jacket would target “The North Face 1996 Retro Nuptse Jacket,” “buy black North Face nuptse,” and the product’s SKU.
• Blog Content: Target informational keywords. Use your blog to answer customer questions, solve their problems, and provide value.
  • Example: A blog post could target “how to choose a winter jacket” or “best waterproof jackets for hiking.” Within the post, you can link to your relevant category and product pages.

This structure creates a logical user journey. A customer might first find your blog post, then click through to a category page to browse, and finally land on a specific product page to make a purchase.

Step 5 – Prioritizing Keywords

You now have a long, organized list of keywords mapped to different pages. But which ones should you focus on first? Prioritization is key to an effective keyword strategy for eCommerce.

Consider these factors when deciding which keywords to target:

• Relevance: Above all, the keyword must be highly relevant to the product or content on the page. Ranking for an irrelevant term will only lead to a high bounce rate.
• High ROI vs. Low Competition: Look for the sweet spot—keywords with decent search volume, high commercial intent, and low competition. These are your “quick wins.”
• Short-Term vs. Long-Term Strategy: Your strategy should be a mix of both.
  • Short-term: Target long-tail keywords with low difficulty. You can rank for these relatively quickly and start bringing in targeted traffic.
  • Long-term: Target more competitive, high-volume keywords. These may take months or even years to rank for, but the payoff can be huge. You can build up to these by establishing authority with your short-term wins.

Start by optimizing your most important pages—your top-selling products and main categories—with the best keywords you’ve found. Then, work your way through the rest of your site.

Common Mistakes in eCommerce Keyword Research

Even with the best intentions, it’s easy to make mistakes. Here are a few common pitfalls to avoid:

• Ignoring Buyer Intent: This is the biggest mistake. Focusing only on search volume without considering intent will bring you the wrong kind of traffic—visitors who aren’t ready to buy.
• Focusing Only on High-Volume Keywords: High-volume keywords are often very broad and extremely competitive. New and smaller stores will struggle to rank for them. A better strategy is to focus on less competitive long-tail keywords.
• Not Updating Your Keyword Strategy: SEO for online stores is not a “set it and forget it” task. Search trends change, new products emerge, and your competitors are constantly updating their strategies. Review and refresh your keyword research at least once or twice a year.

Conclusion

Mastering how to do keyword research for eCommerce is not just an SEO task; it’s a fundamental business activity. A well-executed keyword strategy connects you with customers who are actively looking for your products, driving qualified traffic and increasing sales.

By following this step-by-step guide—from brainstorming seed keywords and understanding your audience to using tools effectively and mapping keywords to the right pages—you can build a powerful foundation for your online store’s growth.

Remember to prioritize keywords based on relevance and intent, and avoid common mistakes like chasing high-volume terms. With a structured and continuous approach, you can turn your website into a magnet for your ideal customers.
