Loose match targets broader and more loosely related terms, which converts worse and finds keywords you would never have thought to bid on.<\/strong><\/p>\n<p>Most sellers run both in one undifferentiated auto campaign, at one bid, then cannot work out why the numbers are mediocre. The two do different jobs. They deserve different bids, separate ad groups, and different expectations.<\/p>\n<p>We run Amazon advertising for client accounts as an Amazon Ads partner and an Amazon SPN Verified Partner. I&#8217;ve found auto campaigns are the most consistently neglected part of a seller&#8217;s account, and also the cheapest keyword research available anywhere on the platform.<\/p>\n<h2>What Are Amazon Auto Campaigns?<\/h2>\n<p><strong>Amazon Auto Campaigns<\/strong> are the easiest way to get started with PPC. There\u2019s no need to do manual keyword research. You simply choose your product, set a budget and bid, and Amazon takes over.<\/p>\n<p>But how does it actually work?<\/p>\n<p>Amazon reads your listing, <strong>title<\/strong>, <strong>bullet points<\/strong>, <strong>product description<\/strong>, and <strong>backend keywords<\/strong>, then matches that content to what shoppers are searching for. Depending on what it finds, your ad can appear for a variety of search terms.<\/p>\n<h3>The Four Auto Targeting Types:<\/h3>\n<p>Auto campaigns have four match types running under the hood. These include:<\/p>\n<ul>\n<li><strong>Close Match<\/strong> \u2013 Targets search queries <em>very similar<\/em> to your product.<\/li>\n<li><strong>Loose Match<\/strong> \u2013 Targets <em>broadly related<\/em> search terms.<\/li>\n<li><strong>Substitutes<\/strong> \u2013 Shows your ad on product pages for similar items.<\/li>\n<li><strong>Complements<\/strong> \u2013 Shows your ad on product pages for complementary items.<\/li>\n<\/ul>\n<p>We\u2019re focusing here on <strong>Close Match and Loose Match<\/strong>, because these determine which <strong>keywords<\/strong> your ads show up for.<\/p>\n<h3>Why Auto Campaigns Matter:<\/h3>\n<ul>\n<li><strong>Fast setup<\/strong>: No keyword selection required.<\/li>\n<li><strong>Great for testing<\/strong>: You can quickly find which search terms perform.<\/li>\n<li><strong>Perfect for new listings<\/strong>: Helps generate initial impressions and clicks.<\/li>\n<\/ul>\n<p>But there\u2019s a downside too:<\/p>\n<ul>\n<li><strong>Limited control<\/strong>: You don\u2019t get to pick the keywords.<\/li>\n<li><strong>Potential for wasted spend<\/strong>: Amazon can show your ad to irrelevant queries.<\/li>\n<\/ul>\n<p>Which is why an auto campaign is best understood as a research instrument rather than a sales channel. Somewhere to test, learn, and refine before scaling the winners into manual campaigns where you actually control the bidding.<\/p>\n<h2>Close Match Targeting: Precision Traffic for High-Intent Shoppers<\/h2>\n<p>Let\u2019s start with <strong>Close Match<\/strong>. This is the auto campaign\u2019s version of being precise, <strong>almost like an Exact or Phrase match<\/strong> from manual campaigns.<\/p>\n<h3>What Is Close Match?<\/h3>\n<p>I&#8217;d think of it as the auto campaign&#8217;s version of phrase match.<\/p>\n<p>Amazon uses <strong>closely related keywords<\/strong> to your listing content. Think of it as targeting shoppers who are searching for exactly what you sell, or something <em>very<\/em> close to it.<\/p>\n<p>If your listing is well-optimized with clear, relevant keywords, Close Match will pick that up and show your ad to high-intent buyers.<\/p>\n<h3>How Close Match Works:<\/h3>\n<ul>\n<li><a href=\"https:\/\/zonhack.com\/zh\/amazon-search-term-optimization\/\">Amazon looks for <strong>search terms<\/strong><\/a> that strongly resemble your product\u2019s <strong>title and description<\/strong>.<\/li>\n<li>These are <strong>tight matches<\/strong>, not loose interpretations.<\/li>\n<li>The intent is typically <strong>high<\/strong>, these are buyers who already know what they want.<\/li>\n<\/ul>\n<h3>Real-World Examples:<\/h3>\n<p>I&#8217;d read these as illustrative rather than as terms to copy.<\/p>\n<p><strong>Product<\/strong>: <em>Pet Shampoo<\/em><\/p>\n<ul>\n<li>Close Match terms:<br \/>\n \u201cpet shampoo for dogs\u201d<br \/>\n \u201corganic pet shampoo\u201d<br \/>\n \u201cpet shampoo for cats\u201d<\/li>\n<\/ul>\n<p><strong>Product<\/strong>: <em>Gel Nail Polish<\/em><\/p>\n<ul>\n<li>Close Match terms:<br \/>\n \u201cgel nail polish red\u201d<br \/>\n \u201cgel nail polish set\u201d<br \/>\n \u201csparkly gel polish\u201d<\/li>\n<\/ul>\n<p>These are <strong>not vague<\/strong> or top-of-funnel queries. These are <strong>clear signals<\/strong> that a shopper is looking for a specific product.<\/p>\n<h3>Why Use Close Match?<\/h3>\n<p>We tested this against manual exact match on the same terms and the gap was narrower than expected.<\/p>\n<ul>\n<li><strong>High relevance<\/strong> \u2192 Better Click-Through Rates (CTR)<\/li>\n<li><strong>High intent<\/strong> \u2192 Better Conversion Rates<\/li>\n<li><strong>Lower wasted spend<\/strong> when combined with smart bidding<\/li>\n<\/ul>\n<h3>How we approach this<\/h3>\n<p>In our experience the split pays for itself within a month, purely because the reporting finally becomes readable.<\/p>\n<p>We usually <strong>increase bids<\/strong> for Close Match in auto campaigns <strong>when aiming for conversions<\/strong>. If a product is in the mid-to-late stage of the buying funnel, Close Match delivers more <em>bang for the buck<\/em>.<\/p>\n<h2>Loose Match Targeting: Broad Reach for Top-of-Funnel Awareness<\/h2>\n<p>On the opposite end, we have <strong>Loose Match<\/strong>, which is less about precision and more about <strong>volume and reach<\/strong>.<\/p>\n<h3>What Is Loose Match?<\/h3>\n<p>In my experience this is the half sellers switch off first and should not.<\/p>\n<p>Amazon shows your ad for <strong>search terms that are loosely related<\/strong> to your product or niche. These could be broader, adjacent, or less intent-driven queries.<\/p>\n<p>This is useful for <strong>brand exposure<\/strong>, <strong>testing markets<\/strong>, or reaching shoppers who are <em>curious<\/em> but not yet committed.<\/p>\n<h3>How Loose Match Works:<\/h3>\n<ul>\n<li>Amazon casts a <strong>wider net<\/strong>.<\/li>\n<li>Ads are triggered by <strong>vague or adjacent keywords<\/strong>.<\/li>\n<li>These are <strong>top-of-funnel<\/strong> searches, where buyers may not know exactly what they want.<\/li>\n<\/ul>\n<h3>Real-World Examples:<\/h3>\n<p><strong>Product<\/strong>: <em>\u201c#1 Teacher Mug\u201d<\/em><\/p>\n<ul>\n<li>Loose Match terms:<br \/>\n \u201cgifts for teachers\u201d<br \/>\n \u201cteacher appreciation gift\u201d<br \/>\n \u201cschool mug\u201d<\/li>\n<\/ul>\n<p><strong>Product<\/strong>: <em>400 Thread Count Cotton Sheets<\/em><\/p>\n<ul>\n<li>Loose Match terms:<br \/>\n \u201cbed linens\u201d<br \/>\n \u201cbath sheets\u201d<br \/>\n \u201chome bedding\u201d<\/li>\n<\/ul>\n<p>These queries <strong>don\u2019t necessarily match your exact product<\/strong>, but they\u2019re in the same neighborhood.<\/p>\n<h3>Why Use Loose Match?<\/h3>\n<p>I have seen a single loose match discovery pay for a quarter of wasted spend.<\/p>\n<ul>\n<li><strong>Reach more people<\/strong> early in the buying journey<\/li>\n<li><strong>Discover new keyword opportunities<\/strong><\/li>\n<li><strong>Test product-market fit<\/strong> in broader contexts<\/li>\n<\/ul>\n<p>But it\u2019s not without risks. The intent is lower, and that often means:<\/p>\n<ul>\n<li><strong>More impressions, fewer clicks<\/strong><\/li>\n<li><strong>Lower conversion rates<\/strong><\/li>\n<li><strong>Potential for wasted ad spend<\/strong><\/li>\n<\/ul>\n<h3>How we approach this<\/h3>\n<p>We <strong>lower our bids<\/strong> for Loose Match and <strong>monitor performance closely<\/strong>. It\u2019s valuable, but only when <strong>tightly controlled<\/strong>.<\/p>\n<p>Loose Match is the <strong>broad match of auto campaigns<\/strong>, and while it can unlock new markets, it needs careful supervision.<\/p>\n<h2>Close Match vs Loose Match: Key Differences, Similarities &amp; When to Use Each<\/h2>\n<p>So now that we\u2019ve explored each match type on its own, let\u2019s compare them side by side.<\/p>\n<p>The difference isn\u2019t just in targeting precision, it\u2019s about strategy, buyer intent, and where your customer is in the <strong>purchase journey<\/strong>.<\/p>\n<p>Here\u2019s a breakdown:<\/p>\n<table>\n<thead>\n<tr>\n<th><\/th>\n<th><\/th>\n<th><\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td><strong>Feature<\/strong><\/td>\n<td><strong>Close Match<\/strong><\/td>\n<td><strong>Loose Match<\/strong><\/td>\n<\/tr>\n<tr>\n<td><strong>Targeting Precision<\/strong><\/td>\n<td>High \u2013 closely aligned with product keywords<\/td>\n<td>Low \u2013 broader and less specific<\/td>\n<\/tr>\n<tr>\n<td><strong>Search Intent<\/strong><\/td>\n<td>High \u2013 buyers know what they want<\/td>\n<td>Medium to low \u2013 buyers still exploring<\/td>\n<\/tr>\n<tr>\n<td><strong>Traffic Volume<\/strong><\/td>\n<td>Moderate<\/td>\n<td>High<\/td>\n<\/tr>\n<tr>\n<td><strong>Conversion Rate<\/strong><\/td>\n<td>Generally higher<\/td>\n<td>Generally lower<\/td>\n<\/tr>\n<tr>\n<td><strong>Ideal Use Case<\/strong><\/td>\n<td>Conversion, efficiency<\/td>\n<td>Awareness, keyword testing<\/td>\n<\/tr>\n<tr>\n<td><strong>Strategy Fit<\/strong><\/td>\n<td>Middle to bottom of funnel<\/td>\n<td>Top of funnel<\/td>\n<\/tr>\n<tr>\n<td><strong>How to approach it<\/strong><\/td>\n<td>Higher bids, watch ACoS, graduate winners to manual<\/td>\n<td>Conservative bids, judge on keywords discovered<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p><strong>Close Match<\/strong> is your <em>sales driver<\/em>. It targets shoppers who are actively searching for products like yours.<\/p>\n<p><strong>Loose Match<\/strong>, on the other hand, is your <em>research assistant<\/em>. It helps you discover how shoppers think, even when they don\u2019t use your exact keywords.<\/p>\n<p>Run both simultaneously. Not as an either or decision, but as two instruments doing separate jobs in the same account.<\/p>\n<p>Both match types target keywords, not ASINs, and they both surface in <strong>Top of Search<\/strong>, <strong>Rest of Search<\/strong>, and <strong>Product Page<\/strong> placements.<\/p>\n<p>The real power comes from knowing <em>when to push<\/em>, <em>when to pull back<\/em>, and <em>when to move data<\/em> from one match type into your manual campaigns.<\/p>\n<h2>The two targeting types nobody talks about<\/h2>\n<p>Every discussion of auto campaigns concentrates on the keyword pair and ignores the other half of the mechanism, which behaves entirely differently.<\/p>\n<p><strong>Substitutes<\/strong> places your advertisement on detail pages for competing merchandise. The shopper is already examining an alternative. Whether this pays comes down to comparison, and comparison is brutal: superior imagery, a stronger rating, or a keener price wins the switch, while an inferior offering simply funds a rival&#8217;s traffic. Audit the pages you actually appear beside before concluding the format underperforms.<\/p>\n<p><strong>Complements<\/strong> positions you beside merchandise a buyer might purchase alongside yours. A lens hood next to a camera body. Replacement filters beside a purifier. Genuinely undervalued where an authentic pairing exists, and money set alight where the relationship is imaginary.<\/p>\n<p>Both accept independent bids, exactly as the keyword pair does. Both deserve isolating into their own ad groups. And both frequently sit switched on, unexamined, absorbing a quarter of an auto campaign&#8217;s expenditure while nobody reviews whether the adjacencies still make commercial sense.<\/p>\n<p>I would audit these annually at minimum. Catalogs shift, rivals emerge, and an adjacency that flattered you eighteen months ago may now situate you beside something demonstrably superior.<\/p>\n<h2>Optimizing close and loose match performance<\/h2>\n<p>Switching them on is not a strategy. Tuning them is.<\/p>\n<h3>Bid each targeting type separately<\/h3>\n<p>Amazon assigns individual bids to close match, loose match, substitutes, and complements. Most sellers never touch them and leave one default across all four.<\/p>\n<p>That is the mistake. We tested identical bids across both types on client accounts and it consistently overpaid for discovery traffic while starving the converting half, which is precisely the wrong way round.<\/p>\n<p>Bid higher on close match where conversion is healthy. Bid lower on loose match and treat that budget as a research ceiling rather than a sales target.<\/p>\n<h3>Watch four numbers<\/h3>\n<p>Automatic campaigns are automatic. Your reporting should not be.<\/p>\n<ul>\n<li><strong>Impressions.<\/strong> Are you visible at all?<\/li>\n<li><strong>Click-through rate.<\/strong> Is the targeting relevant and the listing appealing?<\/li>\n<li><strong>Conversion rate.<\/strong> Do the clicks turn into orders?<\/li>\n<li><strong>ACoS and TACoS.<\/strong> Are you profitable, and is the account growing?<\/li>\n<\/ul>\n<p>A diagnostic worth memorizing. High impressions with weak click-through usually means the targeting is too loose, or your main image is losing the comparison. Healthy click-through with weak conversion means the problem sits on the detail page rather than in the campaign, and no bid adjustment fixes that.<\/p>\n<h3>Build negative keywords deliberately<\/h3>\n<p>Automatic campaigns absorb budget quietly if nobody prunes them.<\/p>\n<p>Two tools do the pruning. <strong>Negative exact<\/strong> blocks one specific search term. <strong>Negative phrase<\/strong> blocks anything containing a phrase, which is blunter and more powerful.<\/p>\n<p>I&#8217;d review search terms monthly at minimum, weekly during a launch, and add negatives for anything that has spent meaningfully without converting. Our guide to <a href=\"https:\/\/zonhack.com\/zh\/optimize-negative-keywords-on-amazon\/\">optimizing negative keywords<\/a> covers doing it without accidentally blocking traffic you wanted.<\/p>\n<h3>Harvest keywords into manual campaigns<\/h3>\n<p>In my experience this is where the real return sits, and it is the step most sellers never reach.<\/p>\n<ol>\n<li>Run close and loose match in <strong>separate ad groups<\/strong>.<\/li>\n<li>Read the search term report and find terms with genuine clicks and conversions.<\/li>\n<li>Move those winners into <strong>manual campaigns<\/strong> on exact or phrase match, where you control the bid precisely.<\/li>\n<li><strong>Negate them in the automatic campaign<\/strong>, so you stop bidding against yourself.<\/li>\n<\/ol>\n<p>That loop turns a passive traffic source into structured keyword research. It takes under an hour a month.<\/p>\n<h3>Separate the targeting types<\/h3>\n<p>I&#8217;d treat this as the first change to make in any account where automatic campaigns have been left running untouched.<\/p>\n<p>Give each targeting type its own ad group, or its own campaign entirely. Cleaner data. Easier budget control. Genuinely granular optimization rather than the illusion of it.<\/p>\n<p>Splitting close match, loose match, substitutes, and complements into four separate ad groups is slightly more setup and considerably more control, and it is the difference between an account you can reason about and one you can only guess at.<\/p>\n<h2>Building a long-term strategy around both<\/h2>\n<p>Beyond weekly housekeeping, the pair occupy distinct positions in your funnel and deserve distinct budgets.<\/p>\n<p><strong>Precision targeting owns the bottom.<\/strong> Shoppers arriving through tightly related queries have already decided what they want. They are choosing a supplier, not a product. Bid confidently, defend the position, and accept a higher cost per click, because a shopper this far down the funnel converts at a rate that comfortably justifies the premium you paid to reach them.<\/p>\n<p><strong>Broad targeting owns discovery.<\/strong> Its output is intelligence, not profit. Vocabulary you had not considered. Adjacent needs your product happens to satisfy. Seasonal language shifting beneath you while you were not watching. Fund it as research with a ceiling rather than as a sales channel with a target.<\/p>\n<p><strong>Allocating between them.<\/strong> A reasonable opening split weights the precise side heavily, perhaps three quarters, leaving the remainder for exploration. Shift the ratio as evidence arrives. A mature catalog in a settled category needs less exploration. A new launch needs considerably more.<\/p>\n<p><strong>Graduating winners.<\/strong> Every converting query discovered through broad targeting belongs in a manual campaign where you control the bid precisely. Harvest monthly, and negate the graduated terms in the automatic campaign so you stop paying twice for the same traffic.<\/p>\n<p><strong>Newer sellers should start here.<\/strong> Manual campaigns before you know your buyers&#8217; vocabulary are guesswork with a budget attached. 30 days of automatic data replaces guessing with evidence. Cheaply, too. In my experience it is the fastest route out of the beginner&#8217;s trap of bidding on the words a founder would use instead of the words a customer actually types.<\/p>\n<h2>Key takeaway<\/h2>\n<p><strong>Close match<\/strong> gives you precision. It converts shoppers who already know what they want.<\/p>\n<p><strong>Loose match<\/strong> gives you reach. It tells you what shoppers actually search for, which is information you cannot buy this cheaply anywhere else.<\/p>\n<p>Used properly, with separate ad groups, deliberate bids, negative keywords, and a monthly review, the pair become a research engine rather than a spend leak. Used badly, they are an auto campaign nobody has opened in four months, which in our experience describes the majority of them.<\/p>\n<p>For where these campaigns sit in a wider plan, our guides to <a href=\"https:\/\/zonhack.com\/zh\/amazon-ad-placement-strategies-for-sellers\/\">Amazon ad placement<\/a> and <a href=\"https:\/\/zonhack.com\/zh\/keyword-targeting-vs-product-targeting-on-amazon\/\">keyword versus product targeting<\/a> cover the next two decisions, and our guide to <a href=\"https:\/\/zonhack.com\/zh\/tacos-vs-acos-vs-roas\/\">TACoS, ACoS, and ROAS<\/a> covers judging the result honestly.

Loose match targets broader and more loosely related terms. Close match converts better, loose match discovers keywords you would not have thought to bid on.<\/p>\n<h3>Should I run close match and loose match in the same campaign?<\/h3>\n<p>Run them in separate ad groups, or separate campaigns entirely. Mixing them makes the data unreadable, because you cannot tell which targeting type produced which result or set a meaningful bid for either.<\/p>\n<h3>Can I set different bids for close match and loose match?<\/h3>\n<p>Yes. Amazon lets you set individual bids per targeting group within an auto campaign, including for substitutes and complements. Use it, since the four do different jobs and one default bid across all of them wastes budget.<\/p>\n<h3>Is close match better than loose match?<\/h3>\n<p>Neither is better in the abstract. Close match is stronger for converting high-intent shoppers, loose match is stronger for discovering search terms and testing demand. Most accounts benefit from both, bid differently and judged against different expectations.<\/p>\n<h3>How do I use auto campaigns to find keywords?<\/h3>\n<p>Run loose match with a modest bid, then read the search term report. Move converting terms into manual campaigns with controlled bids, and add terms that spend without converting as negatives. In our experience this harvest is the most valuable output of an auto campaign.<\/p>\n<h3>How often should I review auto campaign performance?<\/h3>\n<p>Monthly for most accounts, weekly during a launch or after a structural change. These campaigns are frequently set up and then forgotten, which is how a discovery tool quietly becomes a budget leak.<\/p>\n<hr \/>\n<p><em>Last updated: August 29, 2026.
