If you only have a couple of embarrassing or lame Amazon searches that you don’t want to pollute other pages, you can also edit your own search history. First, Amazon’s site saves your recent searches in a “cookie” file stashed in your browser’s settings folder on your computer, then Amazon ads on other sites can then read that cookie to see what product to feature. That’s a consequence of how Amazon does this retargeting. You will, however, have to repeat this on each browser that you use for any Amazon shopping. You may still see Amazon ads, but they won’t be keyed into your recent queries and clicks around the Seattle retail giant’s site.
On that page, click the button next to “Do Not Personalize Ads from Amazon for this Internet Browser” and then click the “Submit” button below it. To do that, visit /adprefs or log into your Amazon account in a browser, click on your username in the top right corner of the page, and then click on the “Your advertising preferences” link. Instead, you can tell Amazon to stop sending you ads based on your shopping habits. But it’s easy to forget to do that when you have 10 different pages open in tabs in your browser and you’re also switching between the Web, e-mail and other apps. You can avoid this problem by doing your online shopping in a private-browsing or incognito-mode window. I realized this firsthand a few weeks ago, when a few searches to check prices for a toilet seat left me staring at Amazon photos of toilet seats through the rest of the evening’s Web reading. But Amazon’s outsized inventory and the time many of us spend there can make its retargeted ads more obvious and obnoxious than most. “Retargeting” - showing you ads for something you’ve looked for at some online store even as you visit other sites, in the hope that the reminder will persuade you to complete the purchase - is a common marketing practice. Every time I look for something on Amazon, I get ads for the same product on every other site.
