Quotes on a company's own website are worth something only when you can check them somewhere the company does not control. That is why these are collected on independent platforms.
LEVRYO has no published client reviews yet, and nothing invented will appear here. A testimonial with no verifiable person behind it is worth less than an empty page, because a buyer who checks and finds nothing stops trusting everything else too.
Structured data follows the same rule: no Review or AggregateRating markup is emitted until there are real reviews to describe.
