Bars: each Monday to Sunday week's average daily spend. Line: rolling 7-day average.
Spend divided by instant-form leads. Rolling line uses the 7 days' total spend over total leads.
Cost per 1,000 impressions.
Form leads as a share of link clicks.
All four studios on one scale.
Each dot is one studio in one week (or month for CPA). The line is the straight-line fit for that studio, and r is its correlation: near 1 means costs rise with spend, near 0 means no link, negative means they fall. Spend and costs both rose over the summer, so part of any link is the season, not the budget.
Full Monday to Sunday weeks only.
Full Monday to Sunday weeks only, form leads.
April to September, six points per studio, so treat the fit as a rough guide.
Ad spend divided by all sales, so it assumes every sale came from ads. October covers 1 to 10 only.
Sales as a share of form leads in the same month. Leads can close the month after, so single months are noisy.
Six full months. October is left out because sales lag leads.
