Frequently asked questions

How many keywords should I target per listing?
Focus on 15-20 primary keywords for your listing copy, with another 50-100 in your backend search terms. Quality matters more than quantity, target keywords with real purchase intent.
Are Amazon keyword search volumes accurate?
No third-party tool has exact Amazon search volumes. Amazon doesn't share this data. All tools provide estimates based on different methodologies. Use them for relative comparison, not absolute numbers.
How often should I update my keywords?
Review keywords quarterly or when you see ranking changes. Seasonal products need more frequent updates. Jarvio monitors keyword performance automatically and suggests updates.
