Account structure is the skeleton everything else hangs on. Get it right and your budget flows to the services that matter, your ads match what people search, and your reporting tells you plainly what is working. Get it wrong and you get a tangled account where one runaway keyword eats the budget, your emergency ads compete with your maintenance ads, and you cannot tell which service is actually profitable. For a trade running real money through Google Ads, structure is not busywork. It is the difference between control and chaos.
The hierarchy is simple to state. An account contains campaigns. Campaigns contain ad groups. Ad groups contain keywords and ads. Budget and most settings live at the campaign level. Ad relevance lives at the ad group level. The whole art of structure is deciding what deserves its own campaign and what belongs together in an ad group.
Campaigns Are Where You Control Budget and Priority
Because budget is set per campaign, you split into separate campaigns whenever you need separate budgets or separate priorities. For a trade, the most useful ways to divide are by service line and by intent.
By service line means a campaign for each major service you want to control independently. An HVAC company might run separate campaigns for AC repair, heating repair, and installation, because those have different values, different seasonality, and deserve different budgets. If they all sat in one campaign, the algorithm and the budget would blur across them and you could not push money toward, say, installation when that is what you want to sell.
By intent means separating emergency or high-urgency searches from research or lower-urgency ones, because an emergency lead is worth more and you may want to bid and budget it differently. Emergency AC not working is a different customer from AC maintenance plan, and putting them in one bucket averages away the difference.
Other legitimate reasons to split into separate campaigns: different geographic areas that need different budgets, or branded searches for your own business name kept separate from non-branded so the cheap, high-converting branded clicks do not distort your prospecting numbers. Anyone searching your business name should be captured in a dedicated, tightly controlled branded campaign.
Ad Groups Are Where You Control Relevance
Within a campaign, ad groups exist for one reason: to keep keywords, ads, and landing pages tightly matched so the ad the searcher sees mirrors the words they typed. The cardinal rule is tight themes. Every keyword in an ad group should be close enough in meaning that a single set of ads speaks to all of them.
If an ad group contains drain cleaning, water heater repair, and toilet installation, no single ad can be relevant to all three, so your ads are generic, your Quality Score suffers, and you pay more. Split them. One ad group for drain cleaning keywords with drain cleaning ads pointing at a drain cleaning page. One for water heaters, and so on. Tighter ad groups produce more relevant ads, better Quality Scores, lower costs, and higher conversion rates.
A workable pattern is a handful of tightly themed ad groups per campaign, each holding a small set of closely related keywords rather than a giant grab-bag.
Keyword Match Types and the Search Terms Report
Inside ad groups, be deliberate about match types. Phrase match and exact match give you tighter control over what triggers your ads; broad match casts wide and, without careful management, pulls in irrelevant searches that waste money. Many local accounts do best leading with phrase and exact match on their money keywords, using broad match cautiously and only alongside smart bidding and diligent negative-keyword work.
Regardless of match type, the search terms report is where structure meets reality. It shows the actual queries that triggered your ads. Review it regularly. Add irrelevant queries as negative keywords so you stop paying for them, and promote strong new queries into their own tightly themed ad groups. This ongoing pruning is what keeps a well-structured account clean over time.
Negative Keywords Protect the Whole Thing
Negatives are as important as the keywords you target. Common ones for trades include jobs, salary, and careers to filter job seekers, free and DIY to filter people who will never pay, and the names of services you do not offer. Build a negative keyword list and apply it across campaigns, then keep adding to it from the search terms report. Without disciplined negatives, even a perfectly structured account bleeds money on searches that were never going to book.
You can also use negatives to keep campaigns from cannibalizing each other. If you run separate emergency and maintenance campaigns, negatives help route each query to the right one instead of both bidding on the same search.
Keep It as Simple as It Can Be
There is a temptation to over-engineer, dozens of campaigns and hundreds of thin ad groups. That is its own failure mode, because thin ad groups and campaigns starve of the data that both you and smart bidding need to make good decisions, and the account becomes impossible to manage. The goal is enough separation to control what needs controlling, and no more.
A sound default for a typical trade: a branded campaign, one campaign per major service line, emergency separated from non-emergency where the volume justifies it, each campaign holding a few tightly themed ad groups, a shared negative keyword list, and conversion tracking feeding it all. That structure gives you real control without drowning you in complexity.
