Chapter 5 left you with a trimmed keyword list: the buyer searches that survived an honest read, sorted into small ad groups by product. This chapter decides what runs first and how Google is allowed to match it.
The short version is that a B2B account launches on exact match and waits for broad match. Exact match buys the searches you already know a buyer types. Broad match goes looking for the ones you don't know yet, and in B2B that search is expensive and hard to watch until the account has proven what a qualified lead looks like. Here's why, with the numbers behind it. If you want the list-building step first, it's in Chapter 5.
"Injection Molding Quote" Gets 170 Searches a Month. That's What Ready to Buy Looks Like in B2B.
Ready-to-buy searches in B2B are small, and that's normal. When we pulled US search volumes for the four kinds of B2B company this guide follows, the searches that ask for a quote barely registered next to the product terms. Across the US, "injection molding quote" logs roughly 170 searches in a typical month. "Cnc machining quote" gets 90 and "online cnc quote" 70, while "cnc machining" by itself reports 135,000.
Searches for a supplier sit between the two: "fastener supplier" at 2,900 a month, "light industrial staffing agency" at 1,300, "injection molding companies" at 1,900. They're bigger than the quote searches and far more focused than the product terms.
These two groups, the quote searches and the supplier searches, are the ones we call buyer intent keywords. They're specific: a product, a service, a part, a request for a price. They're few: a B2B list built this way is short next to the thousands of ideas Keyword Planner returns. And as Chapter 2 showed, advertisers already in these auctions usually bid more for them than for the product term alone.
That makes them the first campaign. Our name for it is Isolation. Every keyword is exact match, every bid is set by hand per ad group, and each product or service gets its own small group and its own page. Isolation is a BrandRocket name, not a Google setting.
Here's what a first Isolation campaign looks like for two of the business types in this guide. Take a managed IT firm first. Its local search, "managed it services near me" (about 9,900 a month nationally), anchors the first group. "Managed it service provider" (5,400) anchors the second. Pricing searches get a third group only when the firm is prepared to publish real price ranges on that page. For a 3PL, one group holds "3pl companies" (8,100), another "3pl fulfillment services" (480), and a third the specific services it actually runs, such as pick and pack or freight forwarding, if the searches have volume. Each group gets an ad that repeats its keywords and a page from Chapter 4 that answers them.
That's a short list on purpose. Every keyword on it is one you've read, decided a buyer types, and can point at the right page. Nothing on it is there because a tool suggested it.
Exact Match Isn't Exact Anymore. Google Also Matches Searches It Decides Mean the Same Thing.
Years ago, an exact match keyword matched only those words in that order. Those days are gone. Google's help page says that with exact match, "Ads may show on searches that have the same meaning or same intent as the keyword." Its list of close variants for exact match includes misspellings and plurals, reordered words, added or dropped words like "for" and "the," implied words, synonyms and searches with the same intent. Google is direct about the choice you have: "There's no way to opt out."
For a B2B account that's mostly fine. A buyer who types "quote for injection molding" means the same thing as "injection molding quote." Where it bites is when Google's idea of the same meaning and yours differ. "Industrial shelving" and "garage shelving" can look close to a model; to a rack maker selling to warehouses, they're different customers.
Two consequences matter for the setup:
- Exact match keeps priority. When a buyer types precisely your exact match keyword, Google gives that keyword first claim on the search, ahead of broad or phrase keywords and ahead of a Performance Max campaign. Isolation keeps the searches that match its keywords word for word after broader campaigns join the account.
- Negatives don't stretch the same way. Google is explicit that negative keywords don't extend to close variants. A negative for "job" doesn't block "jobs." A B2B negative list has to spell out the plurals, synonyms and other variations itself; Google does handle misspellings.
Exact Match Protects the Searches You Know Work. Broad Match Goes Looking for the Ones You Haven't Found.
Our method builds the account from the inside out. The inside is the set of searches you know a buyer types, the list from Chapter 5. Isolation runs them on exact match, with bids you control.
The outside is the long tail: phrasings so particular that no one building a keyword list would ever think to type them in. A purchasing manager types a part description in her own words. An engineer adds a material and a tolerance. A maintenance supervisor uses the name his plant calls the machine. Each of those searches is rare, but together they add up to a real share of what buyers type, and that's where an account eventually grows.
The second campaign goes after them. We call it Exploration: a copy of Isolation seeded with its three to five best keywords, set to broad match, with Google setting bids toward a target cost per qualified lead. Broad match lets Google match searches related to your keyword, not just close to it, and the bidding is what keeps that from turning into a free-for-all.
Practitioners disagree sharply about when, or whether, broad match belongs in a B2B account. One specialist who works with managed IT firms told his audience in 2023 that broad match is "a bad idea so just don't even try it." Specialists in logistics and IT services run phrase and exact match only. Others, including former Googler Jyll Saskin Gales, start on exact and move to broad with Smart Bidding. We sit with the last group, with one firm condition: broad match only after the account has earned it.
Google's Search Terms Report Leaves Out Rare Searches, and B2B Searches Are Rare.
There's a second reason B2B accounts should be slow with broad match, and Google spells it out. The report that lists what searchers typed before clicking your ad has gaps, and Google says so. Google's help page says "Some search terms that don't have enough query activity are omitted from the search terms report in order to keep with our standards on data privacy." Its separate search terms insights view groups some of those into themes, and Google doesn't publish how much goes unshown.
In a consumer account with thousands of searches a day, the gap is likely smaller. In a B2B account, rare searches are the norm. A buyer's exact phrasing may appear once a month. When broad match is running, some of the clicks you pay for will come from searches you'll never see named in the report, which makes it harder to find and block the ones that don't fit.
Exact match keeps that gap smaller, because you chose every keyword. That's not a reason to avoid broad match forever. It's a reason to turn it on only when the account has enough qualified leads for Google's bidding to steer by, and to watch it closely when you do.
Broad Match Copies Your Past Buyers. It Needs About 30 Qualified Leads a Month to Copy From.
Exploration runs on Smart Bidding, where Google sets each bid from what it predicts a click is worth, based on the conversions the account has recorded. That's the mechanism that makes broad match work. It looks for more searches and more people like the ones who became qualified leads before. With too few of those, it has little to go on.
So Exploration waits for volume. Our trigger is roughly 30 qualified leads a month, counted by the tracking set up in Chapter 1. For most accounts that happens around months two or three. An account spending more can hit that mark well before month two. Plenty of B2B accounts take longer, and some never reach it, which Chapter 7 deals with directly.
When it does start:
- Set the target cost per lead from Isolation's real number, not a hope. Google recommends starting from the account's recent actual cost per conversion.
- Open the search terms report daily for Exploration's first month, blocking each wrong search the day it shows up. Expect to find competitor names, job searches and consumer phrasings even after Chapter 5's cleanup.
- Use the account-level negative list for the words that should never trigger any ad, like jobs, careers and salary. It holds up to 1,000 terms and applies across the account's campaigns.
- Keep Isolation running. Searches identical to its exact match keywords still go to it first, and you can scale it back later if Exploration carries the account.
Done in that order, broad match finds searches you would never have thought of, at a price you've already proven you can afford. If the account never gets there, that's a legitimate place to stop, and the next chapter explains how to run it well.
