What is the "_sm_byp" query parameter seen on countless URLs?
Enter &quot;_sm_byp&quot; in any search engine, quotes included, and notice in the results that all the listed URLs have this query parameter -- make sense we searched for it.<p>However, all these URLs are clearly unrelated. How come they all share this parameter? Where does it come from? Maybe there is an obvious answer to this but I&#x27;ve been unable to figure where it comes from.
