Amazon Exact Match gives you 100% control over your ad placements.
Let's be honest. If you are running Amazon PPC right now, you've probably noticed that your tightly controlled Exact Match campaigns are suddenly acting a lot like Broad Match.
You set up an Exact Match keyword to isolate high-converting traffic, but when you pull your Search Term Report (STR), you find your budget bleeding out on irrelevant clicks.
This isn't a mistake on your end - it is a fundamental shift in how Amazon handles semantics.
Amazon’s aggressive push for AI-driven "semantic matching" means your Exact Match keywords are no longer strictly exact. The algorithm is force-feeding plurals, loose synonyms, and "close variants" into your campaigns, whether you want them or not.
Here is what is happening behind the scenes in your ad console:
• You bid strictly on garlic press stainless steel, but Amazon matches you with "metal garlic crusher." You pay for a click, but the buyer was looking for a completely different design.
• You bid on running shoes men, but your ad shows up for "mens jogging sneakers." Your Click-Through Rate drops because the specific intent is slightly off.
• You bid on yoga mat thick, but Amazon expands it to "thick workout mats for floor." Suddenly, your ACOS spikes due to highly competitive, broader intent that you never asked for.
Amazon's goal is to maximize ad inventory and impressions. Your goal is to maximize profitability and Unit Economics.
Right now, those two goals are in direct conflict.
You can no longer rely on match types to do the heavy lifting for you. To stop Amazon from draining your budget on "close variants," you need to adapt your strategy immediately:
• When launching an Exact Match campaign, proactively add known synonyms and variations as Negative Exact keywords. If you are selling a "garlic press," negate "crusher," "mincer," and "squeezer" on day one if they don't convert for you.
• Checking your Search Term Reports once a week is no longer enough. You need to pull them every 48 hours specifically to hunt down and negate Amazon’s auto-expanded terms before they eat your margin.
• If a "close variant" is actually driving profitable sales, don't leave it to chance. Pull that variant out, make it its own dedicated Exact Match keyword, and then negate it in the original campaign. Control the bid, control the placement.
• Often, Amazon will push your ads to top placements for these close variants, charging you a premium CPC for a keyword you didn't even explicitly bid on. Keep your base bids realistic to avoid overpaying for algorithm-generated traffic.
Your Exact Match campaigns need a babysitter more than ever.
Stop letting Amazon's algorithm redefine what "exact" means for your brand.
