We have been cooperating closely with Google and others since 2015 to ensure that the use of Cookiebot does not negatively affect your website's ranking and the indexing of its content or the website's performance. This was an important requirement for Google prior to them officially listing Cookiebot on www.cookiechoices.org.
Cookiebot does not affect the website's performance because the script is delivered in less than 100ms (on average). In automatic cookie blocking mode the script is loaded synchronously in order to apply control over all other scripts loading however in manual mode it can be loaded asynchronously meaning the rest of the website is not waiting for the Cookiebot script to be loaded, further improving performance.
Any search engine crawler will access your website simulating a "full consent" (in effect, the cookie consent banner will not be visible to the crawler). That way the crawler will have access to all content on the website (and not be excluded from certain parts of your website that may not be visible to users who have not accepted certain categories of cookies). The cookie texts from the cookie consent banner are not indexed by the crawler and will therefore not affect the indexation of your website. The cookie consent banner is only shown to a special Adsense version of the Google crawler, which checks the ad partners’ cookie compliance. In other words, the search engine crawler will not "see" or be "blocked" by a Cookiebot consent banner or in any other way be affected by the use of Cookiebot.

Hi, I have read your article but Cookiebot uc.js still shows up in pagespeed as a blocking resource. It takes up more than a second of time. I can imagine that a user will have this the first time but the actual pagespeed should be higher.
Pagespeed should not be able to detect cookiebot in order to verify actual pagespeed.
