Some early lead activity can occur within 1 day after the campaigns go live, but new PPC campaigns generally go into a learning mode for 5 to 7 days almost immediately after being launched. Meaningful optimization typically requires enough conversion data to identify what is producing qualified inquiries which takes approximately 21-30 days AFTER the learning period ends. A structured testing phase can be conducted concurrently to begin refining keywords, ads, and landing pages before scaling.
