In the realm of computers, %00 represents null, meaning there is nothing—it indicates the end point, suggesting that reading should stop here and no further processing is needed. Interestingly, consider a link like this:
<a href="https://www.buyrfidcard.com/" %00 rel="nofollow">buy rfid card</a>
Since many websites automatically add rel="nofollow" to links,
what if that's the case?
<a href="https://www.buyrfidcard.com/%22 %00">buy rfid card</a>
After the first% 22 takes effect,
the actual situation after the change of% 00 interception is
as follows (rel="nofollow" automatically increases):
<a href="https://www.buyrfidcard.com/" %00" rel="nofollow">buy rfid card</a>

Will the rel="nofollow" attribute still take effect? It's not hard to find that when using AI or online search engines to seek answers, different opinions emerge. According to the official statements from search engines, the conclusion is that it depends on whether the server allows %00 to take effect. So, what are your new interpretations on this matter?
