The Indicator Guide to investigating online reviews

How to analyze online reviews and spot suspicious accounts

Businesses love to tout positive online reviews.

From banks and apps to plumbers, restaurants and beyond, companies proudly display virtual badges or real-life stickers that celebrate their high ratings and popularity. Reviews are a great source of information for consumers — as long as they’re real.

The reality is that fake or inauthentic reviews are rampant online. Between 30% and nearly 40% are fake, according to some estimates. People and companies sell reviews as a service, and unscrupulous businesses do their best to game review platforms and systems.

Fake reviews typically take two forms:

  • Favorable reviews and ratings placed by inauthentic accounts

  • Positive reviews placed by real people that were paid or otherwise compensated to give a review

This guide equips you with fundamental knowledge to help you analyze online reviews for signs of inauthenticity. I suggest reading it alongside my investigation into the suspicious reviews for a range of online businesses run by a Pakistan-based scam network.
