How to use the estimate
This is not a promise of performance. It is a planning number. If you need 30 leads, expect a 5% landing page conversion rate, and pay $4.50 per click, you need about 600 clicks, which means about $2,700 in media spend.
For a new account, it is usually better to fund enough traffic for a clear test than to run a tiny budget for months without usable data.
Read the number like an operator
If the estimate feels too high, do not immediately cut the budget. First ask whether the landing page can convert better, whether the target lead count is realistic, or whether a narrower service area would produce cleaner demand.
If the estimate feels affordable, check the operational side. Paid leads lose value quickly when calls are missed, forms are answered slowly, or lead quality is never reviewed.
