For users with higher than average search needs, we've introduced Search Credits. Each Search Credit represents an additional 150 pages of search. (A standard page is 500 words)
Search Credits can purchased directly from the Subscription section of your account. An active subscription is required to purchase new credits.
Standard monthly searches remaining are always used first to preserve your Search Credits.
Search Credits do not expire and unused credits will rollover as long as your PRO subscription is active. If you cancel a subscription with unused Search Credits, those credits are still available up to the end of the term of your subscription (30 days from your last renewal).
