Here's the secret: Get a virus, like Covid, then sneeze on a computer screen displaying the article you wish to go viral. Afterwards, you have to say the words "Go Viral" five times. A bit like saying Candyman five times in the mirror to summon the Candyman, only without then getting gruesomely murdered, and with fewer bees involved.

Afterwards, wipe the screen, sit back, relax, and watch the article go viral. Success guaranteed.
