Google Ads for Law Firms

The standard failure in a multi-practice law firm account is subtle enough to survive for years. Everything looks reasonable. Campaigns exist for each practice area, the budget is spent, leads arrive, and cost per lead sits somewhere in a defensible range. What has actually happened is that a shared budget has quietly reallocated itself toward whichever practice produces the cheapest conversions, an automated bidding strategy has learned to optimize a conversion action that means four different things, and the practices with the highest value per matter are being starved because their leads cost more. The account is working exactly as configured, and the configuration describes a business the firm does not have. This guide covers building an account that respects the fact that practice areas are separate businesses.

1Multi-Practice Account Architecture

Structure should mirror the firm's actual economics rather than its org chart or its website navigation.

• One campaign group per practice area, minimum. Not one campaign with ad groups per practice, which surrenders budget and bidding control at exactly the level where you need it.
• Separate again where economics diverge within a practice. If two matter types under one practice differ substantially in value, they are separate campaigns.
• Geography can differ by practice. A firm may serve one practice statewide and another within a single county. Shared location settings force a compromise that suits neither.
• Schedules can differ by practice. Urgent practices need after-hours coverage. Planning practices do not.
• Device bidding can differ. Some practices are searched almost entirely on phones and others substantially on desktop.
• Label everything by practice. So reporting can be sliced without reconstruction every month.
• Consider separate accounts at scale. Large firms with genuinely independent practice groups sometimes benefit from separate accounts under one manager, particularly where budget authority sits with different partners.

2Why Budgets Must Not Be Shared

Shared budgets are convenient and they are the most common structural mistake in multi-practice legal accounts.

• Money flows to cheap conversions, not valuable ones. A shared budget will drift toward whichever practice converts most easily, which is usually the one with the lowest matter value.
• High-value practices get starved silently. Their higher cost per lead reads as inefficiency rather than as the price of better work.
• Partners cannot verify their allocation. Which turns every budget conversation into an argument without data.
• Seasonal practices distort the rest. A practice with a demand spike will consume shared budget during its peak and leave others dark.
• Capacity changes cannot be actioned quickly. When a practice fills up, you want to cut its spend precisely, not proportionally.
• Set practice budgets from the allocation decision. Growth, maintenance, and constrained practices should have visibly different numbers.
• Review allocation quarterly, not monthly. Frequent enough to respond to capacity, infrequent enough to avoid thrashing.

3Conversion Actions Per Practice

A single conversion action across a multi-practice firm is the technical root of most reporting problems, because the same event means different things in different practices.

• Define a conversion action per practice. So each campaign optimizes toward its own definition of success.
• Assign values reflecting matter economics. Not equal values, or bidding will favor whichever practice is cheapest to convert.
• Set only practice-relevant actions as primary. Secondary actions can be observed without influencing bidding.
• Call conversions need duration thresholds. Above 60 seconds so short calls do not train the algorithm.
• Import retained matters where possible. Offline conversion import per practice is where reporting becomes genuinely useful.
• Accept different attribution windows. A practice with a months-long cycle needs a longer window than one that retains same-day.

4Practices Excluding Each Other

This is the multi-practice problem with no equivalent in single-practice accounts. Your practices generate traffic for each other, and most of it is wasted.

The routing decision matters more than the exclusion. When a term genuinely belongs to two practices, decide which campaign should own it based on which practice you want to grow, then negate it everywhere else. Leaving it in both means they bid against each other and you pay a premium to compete with yourself.

5Bidding Across Incompatible Economics

• Do not run one bidding strategy account-wide. Practices with different conversion volumes and values need different approaches.
• Target CPA per practice, set from matter value. A practice with high matter value can sustain a target several times another's.
• Low-volume practices may need manual control. Automated strategies require conversion volume to learn, and a niche practice may never supply it.
• Value-based bidding only where values are real. Maximize conversion value optimizes toward whatever you told it a conversion is worth, so wrong values produce confidently wrong outcomes.
• Let each practice learn separately. Structural changes to one campaign should not reset learning across the account.
• Seasonal practices need seasonal adjustments. Applied to those campaigns only.
• Do not chase impression share across practices. It is a meaningful target in a growth practice and a waste in a maintenance practice.

6Landing Pages and Practice Matching

• Never send paid traffic to the firm homepage. A generalist homepage asks the visitor to navigate, and paid traffic does not navigate.
• One landing page per campaign, matched to the practice. Speaking only to that matter type, with no cross-practice menu competing for attention.
• Tone must match the practice. Practices whose buyers arrive distressed and practices whose buyers arrive planning require completely different registers, and a shared template serves neither.
• Match the contact method to the practice. Some practices convert by phone and others by form, and forcing one pattern across the firm costs matters.
• Show the relevant attorneys only. A page listing every attorney in the firm dilutes the specialist impression the page needs to create.
• Keep firm navigation minimal on landing pages. Enough for credibility, not enough to lose people into other practices.
• Test per practice. A change that helps one practice's page frequently hurts another's.

7Brand Campaigns for Multi-Practice Firms

• Firm name traffic is practice-ambiguous. Someone searching your firm name may want any of your practices, which makes routing the key decision.
• Send brand traffic to a genuine routing page. Not a homepage that buries practice areas below the fold.
• Individual attorney names deserve their own coverage. Particularly for attorneys with personal reputations, and this traffic is usually high intent.
• Attribute brand conversions carefully. Brand campaigns capture demand other channels created and will flatter themselves in any report that does not account for it.
• Watch for competitors bidding on your firm name. Common in legal and worth monitoring.
• Keep brand budget separate. It should not compete with practice acquisition budget, because it will always win on efficiency and always be the wrong winner.

8Account Governance With Multiple Partners

The account structure is the easy part. The recurring difficulty in firm accounts is that several partners have opinions and one budget.

• Agree the allocation before the quarter, not during it. Mid-quarter reallocation requests are where account discipline dies.
• Give each partner their practice's numbers. Visibility reduces the suspicion that another practice is being favored.
• Name one decision maker. Someone with authority to say no to a partner, or the account is managed by whoever emailed most recently.
• Document capacity constraints in writing. So cutting a practice's spend reads as an operational decision rather than a slight.
• Report practice-level results consistently. Same format every month, so trends are visible and single bad months do not trigger restructuring.
• Escalate structural changes deliberately. Adding a practice to the account is a firm decision with budget consequences for everyone else.

9Reporting Practice by Practice

• Cost per retained matter, by practice. The only figure that means anything, and it is never comparable across practices.
• Never report a firm-wide cost per lead. It is an average of incompatible things and it invites the wrong decisions.
• Consultation-to-retention rate, by practice. Where practices differ enormously and where intake problems show up.
• Matter value by practice and campaign. So allocation rests on revenue rather than volume.
• Cross-practice leakage. Search terms and conversions arriving in the wrong practice's campaign.
• Declined matters by practice. Particularly for practices at capacity, where every lead has a cost and no benefit.
• Attribution windows per practice. Reported with the window stated, since a shared window misrepresents the slower practices.
• Firm-wide spend against firm-wide revenue annually. The one blended number worth keeping, as a sanity check on everything else.
