A keyword extractor is a tool that analyses a URL, piece of text, or listing and automatically identifies the most important keyword phrases within it. A keyword finder is a tool that helps you discover which keywords people are actually searching for in a given niche. TagReveal combines both functions in a single free tool — paste any Amazon, Etsy, or YouTube URL and get a complete keyword analysis instantly.
This guide explains exactly how TagReveal works as both a keyword extractor and keyword finder, why these two functions matter for your Amazon, Etsy, or YouTube success, and how to use the results to improve your rankings and sales.
A keyword extractor analyses existing content — product listings, video titles, URLs, descriptions — and pulls out the meaningful keyword phrases embedded within it. This is different from a keyword generator, which suggests keywords based on a topic. A keyword extractor reveals keywords that are already present and working in real, live content.
For Amazon and Etsy sellers, keyword extraction is particularly powerful because it lets you analyse exactly what keywords successful competitors have embedded in their listings. Instead of guessing at what might work, you extract proven keywords from listings that are already ranking and selling.
TagReveal's keyword extractor works by analysing the URL structure of any Amazon, Etsy, or YouTube link. Amazon and Etsy product URLs contain the listing slug — a condensed version of the listing title — which reveals the seller's primary keyword strategy. For YouTube, TagReveal uses the YouTube API to fetch the actual video title, then extracts and expands the keyword themes within it.
Example: The Amazon URL amazon.com/dp/B0X.../silicone-baby-feeding-set-suction-bowl contains the slug "silicone-baby-feeding-set-suction-bowl". TagReveal extracts this and generates: "silicone baby feeding set", "baby led weaning bowl", "suction bowl baby", "BPA free baby feeding" — all buyer-intent keywords a parent would search for.
A keyword finder goes beyond extraction — it helps you discover keywords you might not think of by expanding from a seed word or phrase into a comprehensive set of related search terms. TagReveal's Smart Engine v2 contains an extensive database of buyer-intent keyword phrases across Amazon, Etsy, and YouTube categories.
When TagReveal identifies product terms from a URL, it does not just return those exact words. It expands each term through its keyword database, surfacing related phrases that real buyers use when searching. A seller who pastes a URL for a crab wall art print does not just get "crab wall art" — they get "crab SVG clipart", "beach crab digital download", "coastal wall art print", "crab art instant download" and more — all real search terms buyers use.
This is what makes TagReveal a genuine keyword finder, not just a keyword extractor. It finds keywords beyond what is literally in the URL, based on a curated understanding of how buyers search within each platform and product category.
Amazon listings have a hidden section called backend search terms — up to 249 bytes of keywords that buyers cannot see but Amazon's algorithm reads when deciding which listings to show for a search. Extracting these backend keywords from competitor listings is impossible through normal browsing — Amazon hides them.
What TagReveal does instead is function as a backend keyword extractor by generating the backend search term keywords most appropriate for your product based on category analysis. When you paste a competitor's Amazon URL, TagReveal analyses the visible listing data and generates keyword suggestions specifically formatted for backend search term use — space-separated, no repetition, no punctuation, within the 249-byte limit.
The long-tail keywords and related terms in TagReveal's results are particularly well-suited for backend search terms — they are the kind of secondary phrases that belong in the backend field rather than the visible title and bullets.
💡 Backend keyword tip: Copy TagReveal's "Long-tail Keywords" and "Related Keywords" sections for use in your Amazon backend search terms field. These phrases are not in your title or bullets but are exactly what buyers search for when looking for your type of product.
As a free Etsy keyword search tool, TagReveal provides something uniquely valuable: category-aware keyword generation. Etsy has strict tag limits — exactly 13 tags, each a maximum of 20 characters. Generic keyword tools ignore these constraints and generate tags that are too long to use, or generate irrelevant terms from the wrong product category.
TagReveal solves this by detecting the Etsy product type automatically from the URL. It identifies whether your listing is an SVG cut file, art print, digital download, jewellery item, clothing, toy or plush, home decor, or wedding item — and generates tags specifically for that category, all within Etsy's 20-character limit, capped at exactly 13 tags.
The result is a set of copy-paste ready Etsy tags that you can use immediately in your listing — no editing for length, no guessing whether they fit. The tool even shows a real-time compliance badge: "Etsy-compliant: 13/13 tags · each tag max 20 characters".
For Etsy sellers, this makes TagReveal the most practical free Etsy keyword search tool available — it understands Etsy's specific requirements rather than just generating generic keywords.
Using TagReveal takes under 60 seconds and requires no account or signup:
Repeat this process for 3-5 top competitors. Build a master keyword list from all results. Use the keywords that appear across multiple competitors most frequently — these are the proven, high-priority terms for your niche.
Paid keyword tools charge $50-200 per month and promise comprehensive data. But for Amazon and Etsy keyword research specifically, the most valuable data comes from the platforms themselves — not from third-party estimates. Amazon's URL structure and Etsy's listing slugs contain real keyword data directly from sellers who are already ranking and selling.
TagReveal extracts and expands this native platform data rather than estimating it. This means the keywords you get from TagReveal reflect how successful sellers actually structure their listings — not a third-party tool's model of what might work.
Additionally, free tools lower the barrier to doing keyword research consistently. When there is no monthly subscription at stake, you are more likely to research keywords for every new listing, check competitors monthly, and iterate based on results. This consistency matters more than any single tool's data quality.
TagReveal vs paid keyword tools: Paid tools give you search volume estimates. TagReveal gives you proven keywords from listings that are already ranking. Both have value, but for competitor keyword analysis and tag extraction, TagReveal's direct approach is often more actionable.
TagReveal organises extracted and found keywords into three categories:
The platform notice below the results explains exactly how to use each set of keywords for the specific platform detected — Amazon, Etsy, or YouTube — so you never have to guess where each keyword belongs.
