How do I find keyword gaps?
To find keyword gaps on Amazon, run a Reverse ASIN lookup on two to four close competitors and compare their keywords against your own listing. Any term the competitor ranks for that does not appear in your title, bullet points, description or backend Search Terms is a gap worth reviewing. A keyword gap is a search term that a competitor listing ranks for but your own listing does not cover. Finding those gaps requires two things: a list of the keywords your listing already includes and a list of the keywords a competitor listing targets. The most reliable way to build the competitor list is with a Reverse ASIN tool. You enter a competitor's ASIN and the tool returns the search terms their listing is likely targeting. Comparing the two lists side by side reveals which terms are absent from your listing. The result is a prioritised list of opportunities: terms with real search volume where your product could be more visible but currently is not. The most efficient method is using a dedicated keyword gap tool. You provide your ASIN and one or more competitor ASINs, and the tool automatically runs the comparison and flags the terms you are missing. Keyword Hunters includes this as part of its competitor research workflow. A manual approach is also possible. Export or note all keywords from a competitor Reverse ASIN report, then search for each term in your listing copy and backend Search Terms. Mark each as covered, partially covered or missing. This works for a small number of competitors but becomes slow with four or more. Whichever method you use, running the analysis across multiple competitors rather than one gives a more complete picture. Keywords that appear in several competitor listings are stronger signals of category-wide demand. A gap report typically shows each competitor keyword alongside its estimated search volume, whether your listing covers it, and sometimes the competitor's ranking position for that term. The most useful gaps to focus on are terms with meaningful search volume that are completely absent from your listing. These are the clearest opportunities: real searches where the competitor may be visible and you are not. Also look for terms where your listing partially covers the phrase. If the individual words appear in your listing but not as a complete phrase, Amazon may not index you for the exact search. Including the full phrase, where it fits naturally, can improve your visibility for that term. Not every keyword gap is worth filling. Ranking gaps by potential impact before acting prevents wasted effort and avoids introducing irrelevant terms into your listing. High-priority gaps are relevant terms with meaningful search volume that are completely absent from your listing. Add these to your title or bullet points first, where indexing weight is highest. If the phrase does not fit naturally in visible copy, put it in backend Search Terms. Medium-priority gaps are relevant terms with lower volume, or phrases your listing partially covers. These are worth testing through backend Search Terms or broad-match PPC before committing to rewriting visible copy. Skip or defer: competitor keywords that do not accurately describe your product, any branded terms, very low-volume phrases and terms that would require stretching your product description to include. Adding irrelevant keywords can attract the wrong shoppers and reduce your conversion rate. Once gaps are ranked, they feed into two workflows: listing optimisation and paid advertising. For listing updates, work high-priority gaps into your title and bullet points naturally, without keyword stuffing. Secondary gaps go into backend Search Terms in order of priority. Review your listing holistically after editing to ensure it reads clearly for shoppers. For PPC, keyword gaps from competitor research are strong candidates for Sponsored Products campaigns. Start with exact match to measure conversion before expanding to phrase or broad. Terms the competitor ranks for organically may have proven commercial intent, making them worth testing at a competitive bid. Revisit your gap analysis every three to six months. Competitor listings change, new rivals enter the category and Amazon's indexing evolves. Regular analysis ensures you catch new gaps before they become a persistent disadvantage.
