Below is a list of tips you can follow to identify and avoid fake online reviews or ratings:

1. Research the review website: What kind of reviews does it specialize in? What do customers say about it?
2. Look for extreme ratings: Large clusters of the same rating can indicate some manipulation.
3. Check for reviews with poor grammar: The presence of grammar or spelling mistakes can be a red flag.
4. Analyze sentiment: When the sentiment in reviews is far-fetched, that can be a sign that the reviews are fake.
5. Use detective software: Companies can use software to detect patterns in user review behavior.
