How to Manage Google Ads Keywords for Agencies (Step-by-Step)

Agencies juggling dozens of accounts need a repeatable keyword management process, not one-off cleanups. This guide assumes you already run Google Ads campaigns for clients and have access to Google Ads Manager (MCC). By the end, you'll have a workflow for google ads keyword management for agencies that you can apply across every account, not just the one you happen to be looking at today.

Step 1: Structure Your Accounts for Multi-Client Keyword Work

Before you touch a single keyword, get your account structure right. If you're still logging into separate Google Ads accounts for each client, switch to Google Ads Manager (MCC), which lets you link every client account under one login and jump between them without re-authenticating. This alone saves hours a month once you're past five or six clients.

Naming conventions matter more than they seem to at first. When a new account manager picks up a client account mid-quarter, they shouldn't have to guess what "Campaign 2 - Copy" means or which negative list applies where. Set a standard format for campaigns, ad groups, and negative keyword lists, something like [Client]-[Service]-[Match Type], so anyone on the team can orient themselves in minutes.

Finally, decide access levels deliberately. Not everyone on your team needs edit access to every client account. Google Ads Manager lets you assign admin, standard, read-only, or email-only access per linked account. Give junior team members or contractors view-only access until they've proven they understand a client's account, and reserve edit rights for people who are actually responsible for that client's results. This one decision prevents a surprising share of the "who changed this bid" conversations agencies have internally.

Step 2: Audit the Search Terms Report Before Touching Keywords

Once your structure is clean, start with the Search Terms report (Campaigns > Search terms in Google Ads) for each client. Sort by cost or clicks first, not conversions, so you can see where budget is actually going before you decide whether it's going to the right place. A search term with high spend and zero conversions is your first stop.

This is also where a lot of agency reporting goes wrong: search terms and keywords are not the same thing, and mixing them up in a client deck makes you look sloppy. A keyword is what you bid on and target, like "commercial roof repair." A search term is what the person actually typed into Google, which might be "commercial roof repair near me" or, less usefully, "how to repair a roof yourself." Your keyword can be matched to dozens of different search terms depending on match type. When you report to a client, be specific about which one you mean.

As you go through each account, keep a running note of terms that show up across multiple clients, not just once. If you manage several local service businesses and you keep seeing "jobs," "salary," or "free" as search terms triggering ads, that's not a one-off problem with a single account. It's a pattern that points to a vertical-wide fix, which sets up the next step. Treating every audit as an isolated event, rather than building a library of known offenders, is one of the main reasons agencies redo the same cleanup work every quarter instead of getting ahead of it.

Step 3: Remove Junk Terms and Build Negative Keyword Lists

Once you've flagged irrelevant search terms, add them as negative keywords, but be deliberate about the level. A negative keyword added at the campaign level only blocks that term in that one campaign. A negative keyword added to a shared list can apply across every campaign it's attached to. Adding negatives at the wrong level is a common mistake: the exclusion looks like it's in place, but it's quietly not applying to the account where the waste is actually happening.

For agencies, shared negative keyword lists are where the real efficiency gains show up. If you manage several local service clients, plumbers, electricians, HVAC companies, they likely share a similar set of junk terms: "jobs," "salary," "free," "DIY," "how to." Build one shared list for that client type and apply it across every relevant account instead of rebuilding the same exclusions one campaign at a time.

This is also where a tool built for the Search Terms report earns its keep. Keywordme is a Chrome extension that sits directly inside Google Ads and lets you remove a junk search term and add it to a negative list with one click, right from the Search Terms report, instead of exporting the report to a spreadsheet, cleaning it up, and re-uploading changes. For an agency running this process across a dozen accounts a week, that's the difference between a five-minute task and a half-hour one, repeated for every client.

A quick checklist for this step:

• Confirm whether each negative should live at the campaign level or a shared list level before adding it.
• Group shared negative lists by client vertical, not by individual client, where the exclusions genuinely overlap.
• Review existing shared lists periodically. A term that was junk for one client last year might be a legitimate service they now offer.

Step 4: Organize Keywords into Intent-Based Groups and Match Types

With junk terms cleared out, turn your attention to how your actual keywords are organized. Grouping keywords by product name alone tends to produce ad groups with mixed intent. Someone searching "roof repair cost" and someone searching "roof repair near me" are both interested in roofing, but one is comparison shopping and the other is ready to call. Cluster keywords by intent, informational, commercial, transactional, so your ad copy and landing pages can match what the searcher actually wants at that moment, rather than a generic offer that fits none of them well.

Match type choice should follow from that same thinking, not be an afterthought. Broad match gives Google the most latitude to match your keyword to a wide range of search terms, which can surface volume you'd otherwise miss, but it needs a well-built negative keyword layer and, per Google's own guidance, works best paired with Smart Bidding so the algorithm has conversion signals to steer toward relevant traffic. Phrase match narrows things to search terms that include the meaning of your keyword phrase, giving you a middle ground. Exact match gives you the tightest control over which search terms trigger your ad, at the cost of some reach. For agencies, the mistake to avoid is applying broad match uniformly across every client without checking whether that account's negative list coverage can support it.

Doing this manually across several accounts is where agency time really disappears: clustering keywords, then applying the right match type to each cluster, then repeating for the next client. Keywordme supports keyword clustering and lets you apply match types instantly from within the Search Terms report, which cuts down the back-and-forth between spreadsheets and the Google Ads interface that this kind of work usually requires. For an agency managing several accounts with similar structures, that consistency matters as much as the speed.

Step 5: Build a Repeatable Optimization Cadence Across Clients

A clean account structure and a good keyword audit are only useful if you repeat them. Set a fixed schedule: weekly search term reviews to catch new junk terms early, and a monthly pass to refresh keyword lists, revisit match types, and check whether shared negative lists still make sense for each client. Without a schedule, the accounts that get attention are the ones with the loudest client, not necessarily the ones that need it most.

Bulk editing is what makes a schedule realistic at agency scale. If you identify a new junk term that applies across five client accounts in the same vertical, you shouldn't have to open each account individually and repeat the same three clicks. Applying the same negative keyword or match type change across multiple accounts at once, through Google Ads Manager's bulk actions or a tool built for that workflow, turns a task that used to take an afternoon into one that takes minutes.

Document the process as an SOP: what gets reviewed, how often, who's responsible, and where the shared lists live. This matters more than it might seem for smaller agencies. Team turnover is normal, and a written process means the next account manager can pick up a client's keyword management without relearning it from scratch or, worse, letting an account drift for a month while they figure it out. A short SOP covering the steps above, structure, audit, negatives, clustering and match types, cadence, is usually enough. It doesn't need to be a long document, it just needs to exist somewhere the whole team can find it.

Step 6: Track Results and Report Keyword Changes to Clients

Once the workflow is running, the last piece is proving it's working. Track before and after metrics on the same keyword set: impressions, cost, and conversion rate. "Performance improved" means nothing to a client without numbers attached to a specific change and a specific time window.

Be precise about attribution in your reporting. Wasted spend saved from adding negative keywords is a different result from new qualified traffic gained by expanding into new keyword clusters. Lumping both into one vague "optimization" line item makes it harder for a client to understand what you actually did, and harder for you to show which part of the work is driving the account forward. Separate the two in your reports, even if it takes an extra line.

None of this is a one-time exercise. New search terms show up continuously as campaigns run, some junk, some genuinely high-intent terms worth adding as new keywords. Revisiting the Search Terms report on your set cadence, rather than only when a client asks why spend went up, is what keeps the account improving instead of just getting cleaned up occasionally and drifting again in between.

Keeping the Workflow Consistent as You Scale

Run this loop on a schedule, and check that negative lists and keyword clusters stay applied consistently as you onboard new clients or scale existing accounts. The structure you set up in Step 1 only pays off if new accounts get folded into it the same way, with the same naming conventions, the same shared negative lists where they apply, and the same review cadence from day one.
