What Are Amazon Backend Keywords?
Amazon backend keywords are hidden words or phrases entered in Seller Central that help Amazon understand what your product is about. Unlike visible keywords in titles or bullet points, backend keywords don’t appear on your product page. They work behind the scenes to influence search rankings.
For example, if you’re selling an “Organic Baby Lotion”, your:
- Title might include: Organic Baby Lotion for Sensitive Skin
- Backend keywords could include: infant moisturizer, baby cream, newborn skincare, hypoallergenic lotion, gentle body lotion
Customers won’t see these, but Amazon’s algorithm will index them, helping your product appear for those queries.
Backend keywords act as a safety net for relevant phrases that couldn’t fit naturally in your listing. According to Amazon’s official guidelines, you’re allowed up to 249 bytes (roughly 30 to 40 words) in the “Search Terms” field. Some categories may now allow multiple 500-character fields, but the principle remains: use the space strategically.
How Do Backend Keywords Work on Amazon?
Amazon’s A10 algorithm uses backend keywords to match your product to customer searches. Think of them as Amazon’s way of understanding the synonyms, variations, and search intent behind your product.
Expand search reach without cluttering listings
Backend keywords let you include extra search terms that don’t fit naturally in your title or bullets. For example, a listing for “yoga mat” can include backend search terms like “exercise mat,” “Pilates mat,” or “home workout gear” to reach more search queries without keyword stuffing.
Target long-tail and low-volume keywords
Long-tail keywords make up over 70% of Amazon search traffic. These phrases (“eco-friendly yoga mat for beginners,” “non-slip travel mug”) have lower competition and higher conversion rates. Adding them to your backend ensures you appear in more specific searches that signal stronger buying intent.
Avoid repetition and optimize space
Amazon ignores duplicate keywords. If “yoga mat” is already in your title, there’s no need to repeat it in the backend. Instead, use the space for complementary keywords like “stretching pad” or “home gym equipment.”
Catch spelling and regional variations
Shoppers might search “backpack,” “backpak,” or “rucksack.” Amazon backend search terms allow you to cover all variations without cluttering visible content. For global sellers, include regional spellings like “colour” and “color” or localized words that shoppers in each country use.
Rank for high-intent phrases safely
Backend search words allow you to target buyer-focused phrases, like “gift for teachers” or “office organizer”, without making your title too long or awkward. These intent-based terms help capture users who are ready to purchase.
Gain an edge in competitive categories
In crowded niches like beauty or supplements, even minor keyword coverage gaps can cost thousands in sales. Sellers who optimize backend search terms typically see a 15-25% increase in organic impressions within weeks of updating listings, based on aggregated data.
Easily update and A/B test
Backend fields are simple to modify, making them ideal for A/B testing. You can rotate low-performing keywords every 30 to 60 days based on Search Term Reports to identify which phrases drive impressions and conversions.
Strategically include solution-based keywords
Modern Amazon SEO goes beyond literal descriptions. Backend keywords should include problem-solving or benefit-driven terms like “pain relief,” “for travel,” or “pet-friendly.” These align with how customers describe their needs rather than just product features.
Tips on How to Optimize Your Backend Keywords on Amazon
Once you understand the importance of backend keywords, the next step is strategic optimization. Here’s how to make the most of every byte.
Start with Smart Keyword Research
Keyword research is the foundation of Amazon SEO. Begin by using tools like Helium 10, Jungle Scout, or MerchantWords to identify high-volume, low-competition terms related to your product. For example, if you’re selling an insulated coffee mug, you might find backend keywords like: “travel tumbler portable drinkware thermal cup gift for commuters.”
Don’t just target obvious keywords. Look for long-tail variations and related intent-based phrases that reflect how real shoppers search.
At beBOLD Digital, one of our home and lifestyle clients used this strategy to refine keywords for a stainless-steel bottle line. By adding intent-based search terms like “eco water bottle for gym” and “sustainable travel flask,” we helped them increase organic impressions by 22% in just 45 days.
Focus on Relevance (Not Repetition)
Amazon’s algorithm rewards relevance. Avoid keyword stuffing or irrelevant words that could hurt indexing. Each term should directly relate to your product’s features, use cases, or benefits.
Instead of repeating “coffee mug” multiple times, diversify with “reusable cup,” “tea tumbler,” or “eco drinkware.”
For instance, when beBOLD Digital optimized a client’s eco-friendly cleaning brand, we replaced repeated keywords like “cleaning spray” with new relevant terms such as “non-toxic cleaner,” “pet-safe disinfectant,” and “natural home spray.” This improved search coverage across multiple high-intent categories.
Add and Optimize Backend Keywords in Seller Central
To add backend search terms, go to Seller Central → Inventory → Manage Inventory → Edit Listing → Keywords tab → Search Terms field.
- Separate words with spaces (not commas)
- Avoid brand names or competitor terms
- Skip filler words like “and,” “for,” or “the”
- Stay under 249 bytes
When we worked with a beBOLD Digital client in the beauty space, filling out optional fields like “Target Audience” (e.g., “women 30+,” “sensitive skin users”) and “Subject Matter” (“hydrating skincare,” “natural moisturizer”) resulted in improved indexing for niche segments, lifting organic traffic by 30%.
Continuously Test and Refine
Backend keywords are not a set-and-forget strategy. Review performance data regularly, every 30 to 90 days, and replace underperforming terms. At beBOLD Digital, we guide clients through quarterly audits using Helium 10 Index Checker and Amazon Search Term Reports to identify trending opportunities. For example, one wellness brand swapped out generic “supplement” keywords for new search-driven phrases like “daily energy booster” and saw a measurable boost in visibility within two weeks.
How to Find the Best Amazon Backend Keywords
Discovering the right backend search terms requires a mix of data analysis and creative insight.
Use Advanced, AI-Powered Keyword Tools
Tools like Helium 10 (Cerebro), Jungle Scout, and MerchantWords leverage machine learning to surface trending and high-performing keywords. They reveal search volume, competition levels, and related terms customers use.
Helium 10’s AI reports can even predict seasonal spikes, ideal for sellers preparing for Q4 or Prime Day.
Analyze Competitors for Keyword Gaps
Perform a reverse ASIN lookup on top competitors to see which search terms they rank for. Identify gaps in your own listings and add those missing phrases to your backend fields. For instance, if competitors rank for “eco yoga mat” and you don’t, you’ve found an easy opportunity to expand visibility.
Use Amazon’s Auto-Suggest Data
Type your primary keyword into Amazon’s search bar and note the suggested phrases that appear. These suggestions reflect real customer searches and can inspire valuable backend keyword additions like “wireless earbuds for workouts” or “baby stroller travel system.”
Combine Data + Intent for Long-Tail Wins
Amazon search words work best when they align with buyer intent. Combine keyword research data with audience insights to craft terms that reflect specific use cases or emotional drivers: “non-slip yoga mat for beginners,” “office mug for remote workers,” or “pet-safe cleaning spray.”
Best Practices for Amazon Backend SEO
Backend SEO works best when treated as an ongoing process that complements your front-end optimization.
- Focus on relevance over quantity. Amazon cares more about how closely a keyword matches shopper intent than how many words you use. Quality always beats volume.
- Include foreign language variants for global reach. If you sell across multiple marketplaces, add regional terms—such as “chaussures de sport” for France or “wanderrucksack” for Germany. These localized keywords improve indexing abroad.
- Refresh every quarter based on performance reports. The Amazon marketplace evolves quickly. Seasonal shifts, trend cycles, and new competitor listings can all change what people search for. Reviewing and updating backend keywords quarterly ensures you stay relevant.
- Combine backend optimization with front-end keyword strategy. The two work hand-in-hand: your title and bullet points capture main search terms, while backend keywords fill coverage gaps. Together, they provide Amazon’s algorithm with a complete picture of your product’s relevance.
