The mysterious usqp=mq331AQCCAE parameter doesn’t seem to cause any noticeable problems at this time.

While Google Analytics has yet to clarify what this string of characters means, there are several plausible explanations for the usqp=mq331AQCCAE organic traffic AMP URL parameter:

1. usqp=mq331AQCCAE is a Google Analytics tracking code.

Most online commentators seem to believe the URL extension is simply a tracking parameter that Google AMP Cache is sending. Google could be using this tracking parameter internally to log some sort of metrics such as clicks from search results.

2. usqp=mq331AQCCAE is a spam referral.

Historically Google's incoming URLs have been "clean,” so it is not clear that this URL parameter is a tracking code from Google. However, because this pattern has been slowly growing on AMP pages and appears to come from nothing but organic traffic sources, it is unlikely to be a spam referral.

3. usqp=mq331AQCCAE is a malware redirect.

Since numerous unrelated sites have reported the same exact usqp=mq331AQCCAE character string, it is not likely to be malware related.
