When you use LinkedIn search URL for adding contacts to your campaign, our app processes one page with results at a time, because we care about your accounts and try to imitate human behavior whenever possible.
It roughly takes one minute to pick leads from a search page. The more pages there are, the more time it takes to process them.
The search is considered complete if one of the conditions is met:
500 leads were added to the campaign
a 100th page was processed
