Credits are equivalent to the number of search engine results pages scanned for a keyword or expression. For example, for 1 keyword expression audited on 2 pages, 2 credits are used.
In one audit campaign, if you wish to audit 10 keywords on 2 results pages, a total of 20 credits will be used. Credit consumption therefore, is linked to the number of pages scanned for every keyword or expression.
Our PPC Visibility Audit tool maps out the number of credits that will be used at the end of an audit setup, before it is launched.
