You can limit keyword in report generation by following methods

2) Change it according to the number of keywords needs to be checked. Ideal number will be between 15 to 20
3) Then increase the frequency of cron execution in a day according to total number of keywords. Eg:
If you have 60 keywords. Then execute cron job 60 / 3 = 20
times a day.
