Amazon Keyword Tools: Boost Your UK Sales

In the fiercely competitive landscape of Amazon, where millions of products and countless sellers vie for customer attention, standing out is paramount. Just as with traditional web SEO (Search Engine Optimisation), the most sought-after and often priciest tools are those that provide the most reliable data. For any keyword, the most critical piece of information is its search volume – the number of times potential customers type (or voice) a specific keyword into a search bar. This metric directly indicates a keyword's potential, or more accurately, a 'key phrase's' potential, as it's often a combination of words.

This point is fundamental for improving the visibility of your product or book on Amazon. If your listing ranks first for a key phrase that no one ever searches for, you'll receive zero clicks and, consequently, no sales. This leads to a crucial question for any Amazon seller or KDP author: How do I choose my Amazon keywords, and more importantly, how do I find out which keywords are genuinely being searched for by my target customers or readers?

The Critical Role of Keywords in Amazon SEO

Keywords are the backbone of discovery on Amazon. When a customer types a query, Amazon's algorithm sifts through its vast catalogue to present the most relevant results. Without the right keywords, even the most fantastic product or captivating book remains hidden. Your goal is to align your product listings with what customers are actively searching for. It's not just about getting found; it's about getting found by the right people who are ready to buy.

Traditional Web SEO vs. Amazon SEO

For traditional web search engines like Google, Yahoo, and Bing, a multitude of tools, both free and paid, offer invaluable keyword data. Tools such as Semrush, Ubersuggest, and Ahrefs are widely recognised in this domain. However, Amazon operates its own unique search algorithm. So, do similar tools exist specifically for analysing Amazon keywords for books or products? The answer, thankfully, is yes!

In this comprehensive guide, we'll reveal our top findings, providing you with a list of powerful tools designed to estimate search volumes and gather other crucial data on your Amazon keywords. We'll review each, highlighting their strengths and weaknesses, and their specific utility in identifying high-potential keywords.

Free Amazon Keyword Tools for Budget-Conscious Sellers

We begin with some excellent news: several free tools can significantly enhance your Amazon SEO without breaking the bank. While they may not offer the full functionality or data accuracy of their paid counterparts, they provide a solid starting point if investment isn't an option.

Ahrefs Amazon Keyword Tool

Ahrefs offers a standalone Amazon Keyword Tool that is entirely free and incredibly user-friendly. Simply input any generic keyword, and Ahrefs will return a list of associated keywords along with their estimated search volumes. This is a superb resource for anyone on a tight budget looking to select the best keywords based on search potential.

• Pros: Very simple to use, provides estimated search volume, excellent for generating initial keyword ideas.
• Cons: Data may not be as reliable as paid tools like Helium10, limited features, frequent CAPTCHA prompts can be frustrating, does not provide keyword ideas from competitor ASINs.

Keyword Tool Dominator (KTD)

The free version of Keyword Tool Dominator limits you to two searches per day. However, it allows you to download search results in CSV format, which can speed up the process of compiling your keyword lists.

• Pros: Enables keyword searches by product (using ASINs), ideal for finding inspiration from competitor products or books, allows category selection for more precise keywords (e.g., 'Kindle Store' or 'Books').
• Cons: Does not provide search volume; instead, it offers a proprietary 'Keyword Rank' indicating popularity, which is an opaque calculation and difficult to verify or compare with other tools.

Chrome Extensions: KDP / Amazon BSR & Keyword Research SEO Tool & Huge Amazon Search Suggestion Expander

These two highly useful and free Chrome extensions won't provide keyword search volumes. Instead, they offer a score and a visual indicator of a keyword's quality, alongside automating the retrieval of suggested keywords directly from Amazon. They are significant time-savers, though paid tools typically offer even more streamlined and automated processes.

• Pros: Time-saving, provides keyword quality scores, automates Amazon's own search suggestions.
• Cons: No search volume data.

Keyword Tool (keywordtool.io/amazon)

This is a complementary tool that exists. In its free version, it provides no volume or other information. Its minimum paid price of $69 per month is often difficult to justify when compared to more comprehensive solutions like Helium10, which offer significantly more value for a similar or slightly higher price point.

Professional/Paid Amazon Keyword Tools

For those serious about their Amazon presence, investing in professional tools can provide a significant competitive edge through more accurate data and advanced functionalities.

Publisher Rocket

Price: $199, lifetime licence (specifically for authors)

As early adopters, we invested in Publisher Rocket to boost our author careers. However, we rarely use it now and regret the purchase for several reasons. Primarily, data is not available for the UK Amazon marketplace (.co.uk). While it might be used for the .com marketplace (where some English language books are sold), the data for French language books there was too infrequent to be reliable or actionable. The tool is also quite limited in features, providing search volumes and other information only for keywords YOU test, unlike more comprehensive tools such as Helium10.

• Pros: Lifetime licence, author-focused.
• Cons: No UK (.co.uk) data, limited features, only provides data for keywords you input.

KDSpy

Price: $69, lifetime licence (specifically for authors)

KDSpy is a tool we genuinely like and have used far more than Publisher Rocket. While keywords aren't its primary strength, it's invaluable for gaining insights into categories and sales of competitor books. With a few clicks, you can uncover royalties, rankings, and sales figures for any book, or even for entire search results pages or category pages. Data can be exported for detailed analysis.

We highly recommend KDSpy if you're looking to:

• Strengthen your analysis of high-potential niches on Amazon KDP.
• Accelerate your understanding of reader intent.
• Deepen your knowledge of competitors and best-selling books in your categories.

KDSpy is particularly effective for detecting potential niches and deciding what books to write to meet market demand.

Helium10

Price: From $39/month (no long-term commitment)

Helium10 is our current favourite, an incredibly comprehensive tool that has delighted the data-driven authors we are. While not exclusively for Amazon KDP authors, it's a powerful e-commerce tool primarily used by Amazon sellers and marketers to find profitable niches, products, and optimise product listings.

Helium10's Strengths:

• Design & Ergonomics: Despite its rich feature set, Helium10 is visually appealing, ergonomic, and surprisingly quick to learn.
• Functionality: It boasts numerous features. As authors, we use perhaps 30% of them, as some modules are more geared towards general e-commerce sellers. However, it includes an Amazon Ads module that acts as a dashboard and can even automate parts of your Amazon advertising campaigns. We primarily use Black Box, Trendster, Cerebro, Magnet², Keyword Tracker, and Adtomic.
• Data Quality: Having tested all the tools in this comparison, Helium10's data appears to be the most reliable, often derived from actual user browsing patterns (Clickstream data).
• Tutorials: A major strength, with clear, high-quality video tutorials for each tool, though only available in English.
• Free Version: While very limited (2 searches per day), it allows you to test the tool's capabilities and data richness, especially for keyword search volumes, which are unavailable in other free tools.

Helium10's Weaknesses:

Helium10 has very few weaknesses. For an author, the sheer number of functionalities can be daunting. A la carte plans are available, allowing you to choose only the modules you need. However, we prefer the comprehensive Platinum plan (£99/month) to continue exploring how Amazon FBA seller methods and tools can be adapted for KDP authors and our clients.

Ahrefs Site Explorer (Paid with Free Limited Access)

While Ahrefs offers a basic free Amazon Keyword Tool, its true power for Amazon sellers comes from its comprehensive Site Explorer. This tool allows you to dive deep into keyword analysis, offering insights unique among keyword tools.

How Ahrefs Site Explorer Helps with Amazon Keywords:

• Accurate Keyword Metrics: Unlike many tools that rely on Google Keyword Planner or Amazon autocomplete, Ahrefs gathers data by studying the browsing habits of thousands of real Amazon users (known as Clickstream data). This provides more accurate and reliable estimates of search traffic. It also offers unique metrics like:
  • Clicks: The typical monthly number of clicks users make on search results for a given keyword.
  • Clicked/Not Clicked: The proportion of searches that result in at least one click on an Amazon search result.
  • Clicks Per Search (CPS): The typical number of clicks on product listings for each search.
  • Return Rate (RR): An indication of the relative frequency of searches for that keyword within a month. No other Amazon keyword tool offers such comprehensive analysis.
• Global Keyword Research: Observe metrics and local search volumes for virtually any keyword in 170 countries. Simply select a new target nation from the dropdown menu. If you're unsure which nation has the most potential, check the 'Global Volume' metric to see the top six countries by monthly searches and the projected global monthly search volume for your phrase.
• Competitor Google Search Terms: Paste any competing Amazon listing's URL into Ahrefs Site Explorer and access the 'Organic Keywords' report to see what keywords it ranks for on Google. This is an excellent additional source of keyword suggestions for your listing, allowing you to see which phrases drive the most organic traffic to your competitors' websites. Focusing on these same keywords can increase your chances of receiving traffic from Google.
• Identify and Export Keywords: Organise and segment your keyword lists into categories for easy management. Need to send your research to a colleague? Export hundreds of keyword suggestions from saved lists or reports with just a few clicks.

How to Perform Keyword Research Using Ahrefs (General Steps):

1. Log in to your Ahrefs account: Access the 'Keywords Explorer' from the main menu.
2. Enter your target keyword: Type your desired keyword or phrase into the search bar.
3. Choose your target country and language: This ensures accurate search volume and competitiveness data for your target audience.
4. Evaluate Keyword Suggestions: Ahrefs will generate a list of keyword suggestions with data on search volume, keyword difficulty, and other metrics. Use filters to refine results.
5. Assess Competition: Use Ahrefs' 'Keyword Difficulty' tool and 'Site Explorer' to determine how challenging it will be to rank for your desired keyword.
6. Save Chosen Keywords: Add relevant keywords to a list for future reference in content creation or website optimisation.

Benefits of Using Ahrefs for Amazon Keyword Research:

• Comprehensive Keyword Data: Ahrefs' frequently updated and extensive keyword database helps you locate relevant keywords for your Amazon products, providing insights into search volume, difficulty, and other metrics.
• Competitor Research: Gain insights into competitors' backlink profiles, keyword positions, and other SEO metrics to refine your own product listing strategies.
• Keyword Difficulty Analysis: Determine the ranking difficulty for your target keywords on Amazon, helping you find less competitive terms.
• Product Listing Optimisation: Ahrefs evaluates your product listing and suggests improvements to make your title, bullet points, and description more keyword-rich and SEO-friendly.
• Amazon PPC Research: Evaluate your Amazon PPC efforts with data on impressions, clicks, and conversions, helping you maximise campaign ROI.
• Time-Saving: Ahrefs offers a wide range of features and insights in one place, streamlining keyword research and competitor analysis.

Best Practices & Keywords to Avoid (Amazon KDP Guidelines)

Amazon provides specific guidelines on best practices and keywords to avoid for book optimisation. Here's a summary of the key points:

• Useful Keywords: Those that describe the setting (geographical, historical), characters, their roles, plot themes (e.g., coming-of-age, forgiveness), and the story's tone (e.g., dystopian, optimistic).
• Discouraged Keywords: Information already used elsewhere (title, subtitle, contributors), subjective claims like "best novel of the year," time-sensitive information ("new," "on sale," "available now"), and terms common to most books in the category.
• Keywords to Avoid: Anything misleading (e.g., an author's name not associated with your book, or any metadata intended for advertising, promotion, or deception), terms reserved for Amazon like "Kindle Unlimited," "Kindle Subscription," "KDP Select." This list is not exhaustive; all keywords must comply with Amazon KDP's Terms and Conditions.

Further advice from Amazon KDP:

• Monitor your book's ranking for targeted keywords and adjust as needed.
• Adapt keywords based on format: readers search differently for an eBook, paperback, or audiobook, so keywords should ideally vary for each format.

To ensure your books stand out in Amazon's increasingly competitive library, you must use the most reliable data to select high-potential keywords. All the Amazon KDP tools discussed here can help you gather this crucial information for your books' visibility and success. Each tool differs, and your choice will depend on the features you need and your budget. Experiment with a few to see which best suits your situation.

Beyond Keywords: Boosting Your Amazon SEO

While selecting the right keywords is an excellent starting point for improving your Amazon optimisation, it's far from the only factor. You must also demonstrate your book's relevance to Amazon's algorithm for those keywords. A significant number of factors come into play, with the most crucial being proof to Amazon that your book sells to readers who discover it by typing in your targeted keywords.

The Power of Reviews

Reviews are one of the most important ranking factors for Amazon. A logical next step after keyword research is to actively seek reviews. By increasing the number of Amazon reviews, you also increase the chances of getting comprehensive comments that include some of your book's important keywords. These will appear high up in the comments and further add to your book's relevance for those keywords.

Cross-Promotions and Launches

How do you signal to Amazon that your book is relevant for your targeted keywords? By sending a significant flow of interested readers to it. One of the best ways to accelerate this flow is by organising a special operation, for example, with other authors who have published books on similar themes. Combine your efforts, temporarily reduce your eBook price to an attractive level to maximise clicks and purchases, and widely communicate this offer to your email subscribers and social media followers.

Ideally, this technique should be employed at launch, by organising a cross-promotion at a promotional price. This is when Amazon's algorithm works hardest to understand which keywords your book is relevant for. However, you can also use it at any time to boost sales and optimisation simultaneously.

KDP Select

The link between Amazon optimisation and KDP Select lies in broadening your readership. Even if they don't read your entire book, readers subscribed to the Kindle Unlimited programme are avid book consumers constantly searching for new titles. This increases the probability that Amazon will consider your books relevant for your keywords.

Amazon Advertising

Amazon Advertising displays your products in the top search results, accompanied by a "Sponsored" label. This is an excellent solution to boost your books and increase short-term visibility. If you can prove to Amazon that your book sells well for certain keywords used in your ads, there's a strong likelihood it will also boost your book in organic rankings for those same and related keywords.

Optimise Your Other Books

Climbing Amazon rankings through keywords can take time. Why not use this time to optimise your other books? Publishing new books and optimising the SEO and keywords of your existing titles will collectively improve your overall ranking.

Amazon Author Page

While it might seem obvious, many authors still overlook this. It's crucial to create your author page and claim all your published books. This enhances your credibility and brand image. This author page is an additional page containing key elements like your author name, book titles, excerpts, cover highlights, and reader comments – all adding weight to each of your books' optimisation.

Share an Amazon Search Link

This trick works particularly well for keywords where your book ranks on the first or second page. When you share your book's link with your audience (e.g., during a promotion or on your website), don't use the direct link. Instead, use a link that directs your readers to the results of an Amazon search for the keyword you want to rank higher for.

For example, if your book "7 Techniques to Save Time" ranks 13th for the high-volume keyword "productivity", instead of sharing the direct link, use: https://www.amazon.co.uk/s?k=productivity

All readers who go to the first link, find your book (currently at 13th place), and click on it, will signal to Amazon that your book is relevant for that keyword. If they purchase the book after this search, it sends an even stronger signal: "The book '7 Techniques to Save Time' is relevant for the keyword 'productivity', and customers often buy it when they find it in search results."

Improve Your Book

If you've ticked all the boxes above, and results still seem disappointing despite your efforts and well-chosen keywords, there might be other barriers that SEO alone can't resolve. Have you optimised all conversion elements? Is your cover suitable for your genre, niche, and subject? Is your book description effective? Does your book's content meet the expectations of readers searching for your keywords? Is it too short or too long? What's your average rating, and how does it compare to competitors?

It's challenging to step back and admit your book might not be quite polished. We know some of our own books have flaws, and despite all our efforts, optimising keywords won't sustainably boost sales for our less polished works. It's part of the journey, and we often focus on content and SEO optimisation for upcoming books.

Relaunch Your Book

A book is never truly dead. You can always attempt to give it a new lease of life by unpublishing and republishing it under a new name, new 'packaging', and even entirely new, improved content. You can change just the 'packaging' – title, subtitle, cover, keywords, and description – taking into account search volumes. Or you can decide to change everything, including the content.

Joanna Penn's "Career Change" is a great example. Published in 2008 as "How to Enjoy your Job… or Get a New One," it never took off. It became a bestseller in 2012, four years after its release, when Joanna relaunched it, considering Amazon SEO. She targeted the right keywords, changed the title, redesigned the cover, and relaunched it with great fanfare: sales multiplied tenfold!

Frequently Asked Questions (FAQs) about Amazon Keyword Tools

Q1: What are Amazon keyword tools and how can they help with keyword research?

A: Amazon keyword tools are software applications or online platforms designed to help sellers and authors identify relevant and high-performing keywords for their product or book listings on Amazon. They assist by providing data such as search volume, competition levels, and related keyword suggestions, which can significantly improve product visibility and sales on the Amazon marketplace. They help you understand how customers search for products like yours.

Q2: How do I choose the best Amazon keyword tool for my needs?

A: The best Amazon keyword tool depends on your specific needs and budget. For beginners or those on a tight budget, free tools like Ahrefs' free Amazon Keyword Tool or Chrome extensions offer basic insights. For more serious sellers and authors, paid tools like Helium10 or Ahrefs Site Explorer provide more comprehensive, reliable data and advanced features like competitor analysis and listing optimisation. Consider factors like data accuracy, feature set, ease of use, and whether it caters specifically to books (KDP) or general products.

Q3: What metrics do Amazon keyword tools provide for keyword research?

A: While basic tools might only offer estimated search volume, more advanced tools like Helium10 and Ahrefs Site Explorer provide a wealth of metrics. These can include estimated monthly search volume, keyword difficulty (how hard it is to rank), click data (e.g., Clicks Per Search, Clicked/Not Clicked ratios), return rate (how often a keyword is searched), and competitor ranking insights. These metrics are crucial for making informed decisions about which keywords to target.

Q4: How can Amazon keyword tools help with product listing optimisation?

A: Beyond just finding keywords, many tools offer features to help optimise your actual product listings. They can suggest where to place keywords within your title, bullet points, and product description to improve SEO. By analysing competitor listings, some tools can also provide insights into what makes a listing successful, helping you refine your own product information to be more keyword-rich and appealing to both customers and Amazon's algorithm.

Q5: Is it worth investing in a paid Amazon keyword tool?

A: For serious Amazon sellers and KDP authors, investing in a paid keyword tool is often highly recommended. While free tools offer a starting point, paid tools provide far more accurate and comprehensive data, advanced features like competitor ASIN analysis, and time-saving automation. This deeper insight can lead to significantly improved visibility, higher rankings, and ultimately, increased sales, making the investment worthwhile for long-term success on Amazon.

Conclusion
