Stop wasting money by finding spend that cannot plausibly create the intended business outcome. A low campaign CPC can still waste the entire budget; an expensive segment can be valuable when it consistently creates profitable customers. Audit the path from query to customer, not only the price column.
Protect measurement first
Test every primary conversion, remove duplicates and confirm values and attribution are reasonable. If tracking is broken, pause or cap spend that depends on it. Do not let an automated strategy learn from page views, unqualified forms or test transactions presented as commercial success.
Remove clearly irrelevant demand
Review search terms, locations, devices, schedules and network performance. Add negative keywords for persistent, unambiguous mismatches. Correct location settings and stop paying for destinations the business cannot serve.
Avoid sweeping exclusions based on a few clicks. Waste prevention should not become demand prevention.
Match the page to the promise
Send each intention to the closest useful landing page. Make price logic, eligibility, location and action visible. A generic home page forces paid visitors to restart their search and makes campaign optimisation appear worse than it is.
Consolidate priorities
Pause obsolete experiments, duplicate coverage and campaigns with no owner. Give each active campaign a goal, budget, measurement method and review date. Small accounts often waste money by spreading limited data across too many structures.
Use decision rules
Define when to investigate, revise, pause and scale. Rules can include tracking failure, irrelevant-term share, cost per qualified lead and customer acquisition threshold. Use ranges and commercial judgement rather than rigidly pausing after an arbitrary number of clicks.
Google's spend management guidance explains average daily budgets, billing data and monthly charging limits. Check the billing report as well as campaign columns so control matches actual charges.
Assign one accountable owner
Someone must review search terms, landing-page changes, sales feedback and billing. An account with many editors and no decision owner accumulates silent waste.
