One signed case can cover a year of marketing, which is exactly why the auction is brutal and why speed to lead decides who wins.
Personal injury is the most expensive marketing auction in law, and the firms that win it are rarely the ones bidding highest. They are the ones who answer the phone first, follow up fastest, and have enough trust built up front that the caller does not shop three more firms before signing.
The money goes out now. It comes back when the case resolves.
A contingency practice fronts everything. Records, experts, filing costs, and the marketing that brought the case in the door, all paid out of cash the firm already has and recovered whenever the matter closes. That gap is what makes personal injury spend hard to steer. If you wait on settled cases to tell you which channel worked, you are adjusting bids with information that is two years old. The closest checkpoint you can actually act on is the signature on the retainer. Grade every source there, with the case type attached, and the auction stops being a guess.
Be visible at the exact moment someone searches after an accident, which means the map pack and Local Services Ads before anything else
Answer every call, including nights and weekends, because a missed call is a case that signs down the street
Build enough trust before the call that the caller stops shopping
Track cost per signed case, not cost per click, because a cheap lead that never signs is not cheap
Grading a channel on cost per lead
Two sources can deliver leads at the same price and put completely different case loads on your books. A purchased lead is sold to more than one firm by design. A call off your own listing is not. Until you know the decline rate behind each source and the case types it brings, cost per lead is a number about advertising, not a number about your practice.
Spending past what intake can absorb
Every lead is money out before a single fee comes in, so a lead that rings out is a straight loss on capital you already committed. Firms in that spot usually add budget instead of adding coverage, which doubles the loss. Buying the hours your leads actually arrive costs less than the extra spend and raises the yield on every channel you are already funding.
One bid for every case type
A rear-end soft tissue claim and a commercial trucking case can cost the same to click and are worth nothing alike once signed. They also tie your money up for very different stretches. Bid them identically and your budget drifts toward whatever is cheapest to acquire instead of the work your firm is built to fund. Split the campaigns by case type, price them separately, route them to different intake scripts.
In this order.
Set what your cash can carry
A contingency practice can only fund so many open files at once. We start there. How many cases your cash supports, which case types you want that money sitting in, and what a signed file of each type returns when it closes. That ceiling sets your bids. And before any budget moves, the leads you already paid for have to get answered, because a missed call is a case you funded and handed to somebody else.
Take the demand that already exists
Google Business Profile and the map pack first, since those calls arrive with no click charge attached. Review cadence is what moves that ranking, and our SEO page covers how. Then Local Services Ads, which bill per lead instead of per click, laid out in full on the advertising page. The order is the point for a firm watching its outlay: buy the cheap demand before you walk into the expensive auction.
Buy the auction with something to show
Search on case-type terms, priced per case type rather than one blended bid, with a negative list that keeps your card away from traffic that was never going to sign. Streaming and social carry the testimonial footage, so your name is familiar before the phone rings. A caller who already knows your firm asks fewer questions and gets to the retainer faster.
Report what the money bought
Call tracking on every source, with the case type recorded on each signed file. The monthly report is one number: cost per signed case, split by source and by case type, next to how long that money has been out. Bids move on that. They do not move on impressions.

What is a good cost per signed case for a personal injury firm?
There is no single benchmark, and an agency that quotes you one is guessing. It moves with your fee, your case mix, and how much of your signed work you keep instead of referring out. Run it on your own numbers: spend for the period divided by the cases that spend signed, split by source and by case type, then set against the average fee those cases carry. For one personal injury client, DeLoach Law Firm, $1,500 in spend returned roughly $15,000.
Should a personal injury firm buy leads or build its own channels?
Both, with the bought side capped. A purchased lead clears fast and fills a slow month, and the vendor is selling that same accident to your competitors at the same hour, so part of what you paid for is a race. Owned channels take months to produce and keep producing after you stop paying. The reason we cap the bought side is cash: a contingency firm can shut off purchased leads the week money gets tight, and it cannot rebuild a ranking or a review base on that timeline.
How fast does a personal injury firm need to answer a new call?
Minutes, not hours. Somebody who just got hurt is still deciding whether they need a lawyer at all, and that window closes on its own. Answer speed is also the only improvement on this page that costs nothing per lead, which is why High Arc Media times your answer rate before touching a budget. For firms that cannot staff every hour, we build AI voice intake that qualifies the caller and books the consult instead of taking a message.
How long before marketing shows up as signed cases?
Signings can start in the first month. DeLoach Law Firm signed three new cases in month one. Fee revenue runs on a separate clock, because the case has to resolve before the firm collects, so we report on signed cases and case type and let the settlements land when they land.
What should a personal injury firm cut when cash gets tight?
Cut by payback length, not by whatever is easiest to cancel. Hold the profile, the map pack, and the campaigns on the case types that sign and close fastest. Pause the experiments and the case types that would tie your money up for years. Under pressure most firms do the reverse and cut the channels they can measure while keeping the ones they cannot. Write the cut order down while the year is good, so nobody is deciding it in a bad month.
You bankroll every case you sign. Make sure the right ones reach you first.
