If your Dynamic Synonyms are not generating and you are seeing the message "We may not have enough search traffic to generate synonyms for you", this is likely due to insufficient search traffic.
Generation of AI Synonyms is mainly dependent on the volume of non-empty searches. In general, most applications need at least 40K non-empty searches per week to find viable AI Synonyms, but this number can be more as it takes into account different variables and use-cases.
Additionally, Dynamic Synonyms are generated every Wednesday and so it can take up to 7 days from registering to see AI Synonyms relevant for your search.
