As of September 2018, Personal Blocklist works in the most recent version of Chrome (version 69.0.3497.100), but it may not work in previous editions.

Click About Google Chrome Wait for Chrome to update if necessary, then click RELAUNCH when prompted. Unlike Block Site, Personal Blocklist doesn't prevent users from accessing blocked websites; however, it does hide the blocked websites from Google search results. For example, if you were to block facebook.com in Personal Blocklist, you'd still be able to open Facebook, but no "facebook.com" websites would appear in Google search results. This is the page from which you'll install Personal Blocklist. It's a blue button in the upper-right side of the Personal Blocklist window. This option appears at the top of the page. Personal Blocklist will install. Unfortunately, blocking individual search results by clicking a link next to them isn't currently possible, but you can block a website from search results by going directly to the website in question. You can also type a phrase into Google to bring up a list of search results and then select the result that you want to hide. It's an image of a white hand on a red background that's in the upper-right corner of the page. A drop-down menu will appear. This link is near the top of the drop-down menu and contains the website's URL after it. Clicking this link prompts the current site's address to be added to Personal Blocklist. It's in the top-left corner of the Chrome window. This confirms your addition to the Personal Blocklist app. Your selected site will no longer return search results in Chrome. Try searching for your website's name in Google search (e.g., if you blocked Facebook, you would type facebook into Google). In the resulting list of links, you should briefly see the link to the website show up, after which it will disappear. Entering the blocked website's URL will still result in the website loading. If you want to block the website from being accessible in Google Chrome, use Block Site to block the website as well. One way that people can use to get around your restrictions is by using incognito mode, but you can enable Personal Blocklist in incognito to fix this problem: Click Select More tools Click Extensions Click DETAILS below the "Personal Blocklist (by Google)" heading. Scroll down and click the grey "Allow in incognito" switch {"smallUrl":"https:\/\/www.wikihow.com\/images\/d\/d5\/Android7switchoff.png","bigUrl":"\/images\/thumb\/d\/d5\/Android7switchoff.png\/35px-Android7switchoff.png","smallWidth":460,"smallHeight":394,"bigWidth":"35","bigHeight":"30","licensing":"<div class="mw-parser-output"><p>I edited this screenshot of an Android icon.
