Is Google Ads Worth It for Law Firms? How to Decide Before You Spend

Google Ads is usually worth considering when three things are true:

If any one of these is missing, a campaign is likely to disappoint, however well the account is built.

Fit varies more by practice than by firm size. As a general guide:

Some commercial work does sit in the stronger column. Business owners do search for help with specific, pressing issues, such as an employment tribunal claim, a shareholder dispute or a commercial lease problem. But the general rule holds: the more a buyer relies on recommendation and reputation, the less paid search will do on its own.

Before spending anything, work out the most you can afford to pay for a click. You need four figures, from your own data where possible:

1. Value of a typical instruction. The average fee for a new matter in that practice. Include repeat work only if it is genuinely likely.
2. Acceptable acquisition cost. How much of that fee the firm is willing to spend to win the matter.
3. Click-to-enquiry rate. The share of paid visitors who call or submit a form.
4. Enquiry-to-instruction rate. The share of those enquiries that become paying matters.

Then work through it:

These figures are for illustration only, not benchmarks. The point is the method. If the keywords you need typically cost more than your maximum, the campaign cannot pay for itself unless something changes: a better landing page, faster enquiry handling, a narrower focus on the most valuable services, or a higher-value practice.

Two cautions. First, most firms do not know their enquiry-to-instruction rate by source, and without it the calculation is a guess. Second, the management fee and landing page costs sit on top of the click cost, so include them before deciding.

The cost of Google Ads for a law firm is more than the click price. A realistic budget includes:

• Advertising spend, paid directly to Google. Costs per click vary widely by practice, location and competition, and change over time. Google's Keyword Planner gives current estimates for your own searches and area.
• Management, whether by an agency, a freelancer or someone in-house. Accounts that are set up and left alone become less efficient.
• Landing pages, written for each campaign theme.
• Tracking, for forms and calls, and ideally a link to the firm's CRM or case management system so you can see which enquiries became matters.
• Intake time. Paid search generates enquiries that need answering, qualifying and following up. That time is a real cost, especially if many enquiries are not the right fit.

A budget spread across every practice and location usually produces a few expensive clicks for each and teaches you very little. A focused campaign on one or two priority services usually tells you more, and sooner.

When campaigns fail, the cause is usually one of these:

• Too broad. Without careful keyword choice and negative keywords, ads appear for job seekers, students, people looking for free advice and services the firm does not offer.
• The wrong page. Paid visitors arrive with a specific problem. Sending them to the home page or a general practice page wastes much of what the firm paid for. Our guide to law firm practice area pages covers what a page that converts needs.
• Slow or missed responses. A client with an urgent problem often contacts several firms. Calls that go to voicemail, and forms answered the next day, lose instructions the firm has already paid to attract.
• Measuring the wrong thing. Clicks and form fills are not instructions. A campaign optimised for enquiry volume can fill the inbox with work the firm does not want.
• No time to learn. Campaigns need enough data to settle. Judging, and constantly changing, a campaign in its first few weeks usually produces noise rather than answers.

Firms often ask which is better. They do different jobs.

For many firms, the sensible answer is both, in proportion. Paid search covers priority services while organic visibility builds, and its search term data shows which searches actually lead to enquiries, which helps decide where to invest in law firm SEO. Our guide to how long SEO takes for law firms explains the timeline.

There is one form of paid search that most firms should consider whatever they decide about the rest: bidding on the firm's own name.

People who search for a firm by name are often referrals, existing clients or people who have already chosen. If a competitor or an intermediary is bidding on that name, those people may see someone else first. Brand campaigns are usually inexpensive because the ad is highly relevant to the search, and they protect referrals the firm has already earned. Check what appears when you search for your firm's name, on mobile and desktop, before deciding.

Local Services Ads. Google has introduced Local Services Ads for legal firms in some areas, including London. They appear above standard search ads, use a pay-per-lead model and carry a "Google Screened" badge after verification checks. Availability, practice categories and terms change, so check what is currently offered in your area, and read the terms on how enquiries and data are handled before signing up.

Microsoft Advertising. Bing's audience is smaller, but it often skews towards desktop and workplace users. For some commercial and professional services, it can reach useful searchers at a lower cost. It is usually a second step after Google Search is working.

Automated and display campaigns. Formats such as Performance Max spread spend across search, display, YouTube and other placements with limited visibility into where the money goes. For law firms, where the right search matters more than reach, start with standard search campaigns you can see into and control. Treat automated formats as a later test, not a starting point.

For SRA-regulated firms, paid search ads and their landing pages are publicity and must meet the same standards as the rest of the firm's marketing:

• Accuracy. Publicity must be accurate and not misleading, including information about charges. Phrases such as "fixed fee", "no win, no fee" or "specialist" need to be accurate and properly explained.
• Advertising codes. Paid search ads also fall under the UK Code of Non-broadcast Advertising (the CAP Code), enforced by the Advertising Standards Authority.
• Transparency Rules. Campaigns for services covered by the SRA Transparency Rules, such as residential conveyancing and uncontested probate, should lead to pages that carry the required price and service information.
• Unsolicited approaches. Search ads respond to something a person chose to search for. Remarketing, display and audience-targeted formats reach people who did not ask, so consider them against the SRA's rule on unsolicited approaches to members of the public before using them.
• Tracking and data. Conversion and call tracking rely on cookies and personal data. Make sure consent, the privacy notice and any data shared with ad platforms comply with UK GDPR and the cookie rules.
• Competitor names. Bidding on another firm's name as a keyword is a different matter from using its name in ad text. Take a considered approach and take advice where needed.

If the firm already runs Google Ads, look for these warning signs:

• No one can say how many instructions the campaign produced last quarter.
• The search terms report shows many irrelevant searches.
• Paid traffic goes to the home page.
• The account is managed by a provider who owns it, or the firm cannot log in.
• Reports focus on clicks, impressions and "leads", not matters.
• Fee earners describe the enquiries as poor quality.
• The account has not changed in months.

Any of these is a reason to review the account before deciding whether paid search works for the firm. A poorly run campaign answers a different question.

If the numbers might work, a structured test is better than a large commitment or a half-hearted trial:

1. Choose one or two services. Pick the practices where the fit is strongest and capacity exists.
2. Set the decision criteria first. Agree the maximum cost per instruction the firm will accept and how many instructions would count as success.
3. Build the foundations. Focused campaigns, negative keywords, a landing page for each service, call and form tracking, and a way to record which enquiries became matters.
4. Agree how enquiries will be handled. Who answers calls, how quickly forms are followed up and how enquiries are recorded.
5. Run it for long enough. Allow enough time and budget for the campaign to gather meaningful data, often around three months, with sensible adjustments along the way rather than constant changes.
6. Decide on evidence. Compare the cost per instruction with the criteria you set. Scale up, refine or stop.

The firm should own the Google Ads account and its data from day one, whoever manages it, so that the test's results stay with the firm whatever it decides.

If most boxes are ticked, a focused test is worth considering. If several are not, fix those first: they will decide the result more than the campaign itself.
