Should Your Law Firm Advertise on Google? Costs, ROI, and What to Expect

Legal search terms are consistently among the most expensive categories in Google Ads - personal injury and criminal defence keywords in major Canadian cities can run well into double digits per click. Before committing a budget, it's worth understanding why that's true and what a realistic outcome actually looks like.

Why legal clicks cost so much

Cost per click in Google Ads is driven largely by auction competition - how many advertisers are bidding on the same keyword and how much a client is worth to them. Because a single retained client can be worth thousands of dollars in fees, firms are willing to bid high, which pushes the price of every click up for everyone else targeting the same terms, regardless of firm size.

What a realistic starting budget looks like

A meaningful test budget depends heavily on practice area and city, but a firm should generally expect to spend enough to gather at least a few dozen clicks a week in order to learn anything - a budget too small to generate meaningful data will mostly just demonstrate that ads are expensive without telling you whether they'd actually work at scale. Starting narrow (one practice area, one city) and expanding once you see real conversion data is safer than a broad campaign from day one.

Search ads vs. Local Services Ads

Standard Google Search ads put you in the sponsored results above organic listings, targeted by keyword. Google's Local Services Ads (where available for legal services) work differently - pay-per-lead rather than pay-per-click, with a Google-verified badge - and can offer more predictable costs, though availability and category coverage varies. It's worth checking whether Local Services Ads are available for your practice area and region before committing to a standard search campaign.

The landing page matters as much as the ad

A high-quality ad sending traffic to a generic homepage, rather than a page specifically about the service and city the ad targeted, wastes a meaningful share of that expensive click. A dedicated landing page - clear headline matching the search intent, a visible phone number, a simple way to get in touch - converts noticeably better than sending paid traffic to a general page and hoping they find their way to the right information.

When ads make more sense than SEO (and vice versa)

Ads make the most sense when you need clients now, in a practice area with real urgency (criminal, injury, family), and you have a budget you can afford to spend while you learn what converts. SEO and directories make more sense as a longer-term, lower-cost complement that keeps producing traffic without ongoing spend - most firms with a healthy client pipeline eventually run some mix of both rather than relying on either exclusively.
