Thanks, the &quot;issue&quot; was an illustrative example, however I am a <i>relatively</i> tech savvy person and I use google frequently and I didn&#x27;t know about this feature. I would be interested to know what percentage of searches leverage it relative to people who type recent year&#x2F;date into the box for just a quick and dirty statistic about visibility.<p>I don&#x27;t actually want to filter backend technology, but I would like to communicate to the search engine that I do not trust (nor want to have returned as a result) any wordpress, blogger or medium website, and I want their rank to be negative.<p>That is another extreme example, however to discover new things is hard and to find useful information, when communities of bad actors have spent years incentivized to rank higher but not produce quality, it could be easier to simply delist everything and gradually add websites you trust to have authority.
