If you are using seo panel 3.2 or above version, you can limit each cron execution to check only few keywords. But you need to execute cron more than 1 time day according to the number of keywords.
You can limit keyword in report generation by following methods
1) Go to Admin panel => Reports Manager => Report Settings => Number of keywords needs to be checked in each cron execution:
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.
