CPR stands for Cerebro Product Rank. The CPR formula removes the guess work out of product launch giveaway to help your product ranking at the top of page 1 for your desired keywords. Basically, in simple words CPR 8-day giveaway is an option in Helium 10 tool that provides a number which shows that you must giveaway provided number items in 8 days to rank your product on 1st page. According to Enabler criteria less than 600 CPR 8-day giveaway is recommended.

Example:
Keyword= Garlic Press

CPR-8 Day= 160 (total Giveaways in 8 days)

One day Giveaway= 160/8=20 per day

If you maintain that 20 giveaways per day for 8 days then most probably you would be ranked on top positions of page 1 against that KW.

Note: Sometimes you got ranked before that calculated numbers and sometimes take a bit more time.
