Lead Generation Terms
Cost Per Lead (CPL)
Cost per lead is the amount paid for each lead received. In personal injury lead generation, CPL is calculated by dividing total marketing spend by the number of leads generated. Personal injury CPL ranges from $20 to $600 depending on lead source, exclusivity, geographic market, and case type. Google Ads leads typically cost $100-$500 per lead, while social media leads may cost $20-$100 but convert at significantly lower rates. CPL alone is an incomplete metric. Cost per signed case is more meaningful because it accounts for lead quality and conversion rate. See our complete pricing guide for detailed benchmarks.
Cost Per Signed Case (CPSC)
Cost per signed case is the total marketing spend divided by the number of cases signed from that spend. CPSC is the most important metric in personal injury lead generation because it measures what you actually pay to acquire a new client. A lead source with a $50 CPL and 5% conversion rate produces a $1,000 CPSC. A lead source with a $200 CPL and 30% conversion rate produces a $667 CPSC. The "expensive" leads are often cheaper per signed case. Every firm should track CPSC by channel, case type, and lead source.
Conversion Rate
Conversion rate is the percentage of leads that progress to the next stage of the sales process. In personal injury, conversion rate is measured at multiple stages: lead-to-contact rate (percentage of leads successfully reached), contact-to-consultation rate (percentage of contacted leads that schedule a consultation), and consultation-to-signed-case rate (percentage of consultations that become retained clients). The overall lead-to-signed-case conversion rate for personal injury leads ranges from 1-3% for low-quality sources to 15-30% for high-quality exclusive leads. See our complete guide to personal injury lead conversion rates for industry benchmarks.
Exclusive Lead
An exclusive lead is a lead that is sold to only one buyer. In personal injury lead generation, an exclusive lead means only one attorney or law firm in a given practice area and geographic region receives the lead. Exclusive leads have significantly higher conversion rates than shared leads because there is no competition for the prospect's attention. Injury Lead Gen delivers 100% exclusive leads. Every lead is sent to one attorney only. Learn more about exclusive vs shared leads.
Shared Lead
A shared lead, also called a non-exclusive lead, is a lead that is sold to multiple buyers simultaneously. In personal injury, shared leads are typically sold to 3 to 8 attorneys at the same time. Shared leads cost less per lead than exclusive leads but have significantly lower conversion rates because multiple firms are competing to contact and sign the same prospect. The first attorney to call often wins, creating a race condition that favors firms with the fastest response times. Most data shows that exclusive leads deliver better cost per signed case despite higher per-lead pricing.
Lead Source
Lead source is the marketing channel or platform from which a lead originates. Common personal injury lead sources include Google Ads (pay-per-click search advertising), Google Local Service Ads, social media advertising (Facebook, Instagram, TikTok), organic search (SEO), referrals, and television/radio. Lead source is the single most important factor in lead quality. Google Ads leads, generated when someone actively searches for a lawyer, convert at 5-10x the rate of social media leads, where prospects are passively interrupted by advertising. See our detailed comparison of Google Ads vs social media leads.
Speed to Contact
Speed to contact is the time elapsed from lead delivery to the first contact attempt with the prospect. Speed to contact is the number one factor in personal injury lead conversion, after lead source and exclusivity. Data shows that the attorney who calls first signs the case 78% of the time. Leads contacted within 60 seconds convert at dramatically higher rates than leads contacted after 5 minutes, 30 minutes, or hours. Best practice is to contact every new lead within 60 seconds of delivery. Read our complete guide to speed to contact for personal injury leads.
Lead Replacement
A lead replacement policy is a guarantee from a lead generation company that invalid leads will be replaced at no cost to the buyer. Invalid leads include wrong phone numbers, duplicate submissions, people not actually seeking legal help, and leads outside the contracted case type or geographic area. A lead replacement policy ensures that clients only pay for genuine leads. Injury Lead Gen offers an industry-leading lead replacement policy. Any lead that does not meet quality standards is replaced at no charge.
Contact Rate
Contact rate is the percentage of leads successfully reached by phone or other communication channel. Contact rate is calculated by dividing the number of leads successfully contacted by the total number of leads received. A strong contact rate for personal injury leads is 60-80%. Low contact rates often indicate poor lead quality, slow response times, or insufficient follow-up attempts. Improving contact rate through faster speed to contact and multiple follow-up attempts is one of the highest-leverage changes a firm can make.
Intake
Intake is the process of qualifying a new lead, gathering case information, and signing them as a client. In personal injury law firms, intake typically involves an initial phone call to assess the case, collection of accident details and injury information, a determination of whether the case meets the firm's criteria, and execution of a retainer agreement. Firms with dedicated intake specialists or teams consistently outperform firms where attorneys handle intake themselves, because the intake process is handled faster, more consistently, and without competing priorities.
Lead Qualification
Lead qualification is the process of determining whether a lead meets the criteria for a viable personal injury case. Qualification criteria typically include: the lead was involved in an accident caused by another party's negligence, injuries were sustained that required medical treatment, the statute of limitations has not expired, the accident occurred in a jurisdiction the firm serves, and the case type matches the firm's practice areas. Effective lead qualification ensures attorneys spend their time only on prospects with legitimate cases.
Return on Investment (ROI)
Return on investment is a measure of the profitability of a marketing expenditure. ROI is calculated using the formula: (Revenue - Cost) / Cost x 100. In personal injury marketing, ROI is calculated by comparing the attorney fees collected from cases generated by a specific marketing channel to the total cost of that channel. For example, if a firm spends $10,000 on lead generation and signs cases that produce $100,000 in fees, the ROI is 900%. A positive ROI means the marketing is profitable. Personal injury firms should calculate ROI by channel to determine where to allocate budget.
Advertising and Marketing Terms
Google Ads (PPC)
Google Ads is Google's pay-per-click (PPC) advertising platform that allows businesses to display ads in Google search results and across Google's display network. In personal injury marketing, Google Ads is the primary method for reaching prospects who are actively searching for legal help. Advertisers bid on keywords like "car accident lawyer" or "personal injury attorney near me" and pay each time someone clicks their ad. Google Ads for personal injury is one of the most expensive verticals, with cost per click ranging from $50 to $300+, but it delivers the highest-intent leads of any digital channel. Learn more about how Google Ads leads compare to social media leads.
Google Local Service Ads (LSA)
Google Local Service Ads are a pay-per-lead advertising product from Google designed for local service providers, including personal injury attorneys. LSAs appear at the very top of Google search results, above standard Google Ads. Attorneys must pass Google's screening process to earn a "Google Screened" badge. Unlike traditional Google Ads where you pay per click, LSAs charge per lead, so you only pay when a prospect contacts you through the ad. LSAs are a valuable supplement to standard Google Ads campaigns but offer less control over targeting and volume.
Search Engine Optimization (SEO)
Search engine optimization is the practice of improving a website's visibility in organic (unpaid) search engine results. For personal injury law firms, SEO involves optimizing website content, building authoritative backlinks, managing local citations, and creating content that ranks for relevant search terms. SEO is a long-term strategy that typically takes 6-12 months to produce results but generates leads at zero marginal cost once rankings are achieved. Local SEO, optimizing for map pack results and "near me" searches, is especially important for injury attorneys. Read our complete personal injury marketing guide for a full breakdown of SEO vs other channels.
Social Media Advertising
Social media advertising is paid advertising on platforms such as Facebook, Instagram, TikTok, and LinkedIn. In personal injury marketing, social media ads interrupt users who are browsing their feeds, unlike Google Ads, where users are actively searching for legal help. This fundamental difference in user intent results in significantly lower lead quality. Social media leads for personal injury typically convert at 1-3%, compared to 15-30% for Google Ads leads. Social media is most effective for remarketing (re-engaging website visitors) and brand awareness rather than direct lead generation.
Cost Per Click (CPC)
Cost per click is the amount an advertiser pays each time someone clicks on their ad. In Google Ads, CPC is determined by an auction system where advertisers bid on keywords. Personal injury has some of the highest CPCs in all of Google Ads, with average costs ranging from $50 to $300+ per click depending on keyword, geographic market, and competition. CPC is a cost input that ultimately affects cost per lead and cost per signed case, but a high CPC does not necessarily mean poor ROI if conversion rates are also high.
Landing Page
A landing page is a standalone web page designed specifically to convert visitors from an advertising campaign into leads. In personal injury marketing, landing pages typically feature a clear headline addressing the prospect's situation, a simple lead capture form, trust signals such as case results and reviews, and a prominent phone number. Effective landing pages are focused on a single conversion action and remove navigation and distractions that might cause visitors to leave without submitting their information. Read our conversion tactics guide for landing page optimization tips.
Call Tracking
Call tracking is the practice of assigning unique phone numbers to different marketing channels to track which channels generate phone calls. Call tracking software such as CallRail, CallTrackingMetrics, or Invoca allows firms to attribute phone call leads to specific Google Ads campaigns, website pages, or marketing channels. Call tracking is essential for personal injury firms because a large percentage of leads come via phone call, and without call tracking it is impossible to accurately measure the ROI of individual marketing channels.
Legal Industry Terms
Personal Injury (PI)
Personal injury is an area of law that deals with cases where a person has been physically or psychologically injured due to the negligence or wrongful conduct of another party. Personal injury encompasses a wide range of case types including auto accidents, truck accidents, motorcycle accidents, rideshare accidents, slip and fall incidents, workplace injuries, wrongful death, medical malpractice, product liability, and dog bites. Personal injury attorneys typically represent plaintiffs (the injured party) and work on a contingency fee basis.
Case Value
Case value is the estimated or actual monetary value of a personal injury case, typically measured as the total settlement or verdict amount. Case value varies dramatically by case type and injury severity. Average personal injury case values by type are approximately: auto accident $15,000-$75,000, truck accident $50,000-$500,000+, motorcycle accident $25,000-$150,000, slip and fall $15,000-$100,000, wrongful death $500,000-$5,000,000+, and workers' compensation $20,000-$100,000. These ranges are broad generalizations. Actual case values depend on injury severity, liability, insurance coverage, and jurisdiction.
Statute of Limitations
The statute of limitations is the legal deadline by which a personal injury lawsuit must be filed. Statutes of limitations vary by state and case type, typically ranging from 1 to 6 years from the date of injury. The statute of limitations creates urgency in personal injury lead generation because prospects who wait too long may lose their right to file a claim. This is one reason why speed to contact matters. Reaching a lead quickly increases the chance of signing the case while the prospect is motivated and the statute has not expired.
Contingency Fee
A contingency fee is a payment arrangement in which an attorney's fee is a percentage of the client's settlement or verdict, paid only if the case is won. Contingency fees are the standard payment structure in personal injury law. Typical contingency fees range from 33% (one-third) for pre-litigation settlements to 40% for cases that go to trial. The contingency fee model means personal injury attorneys bear the financial risk of taking a case. If the case does not result in a recovery, the attorney receives no fee. This model also means that marketing costs are an investment against future contingency fees.
Signed Case / Retained Client
A signed case, also called a retained client, is a lead who has executed a retainer agreement (also called an engagement letter or fee agreement) with a law firm. The signed case is the ultimate goal of lead generation. It represents a committed client whose case the firm will pursue. The metric "cost per signed case" measures how much marketing spend is required to generate one signed case. In personal injury lead generation, the conversion from lead to signed case depends on lead quality, speed to contact, intake process effectiveness, and case qualification criteria.
Demand Letter
A demand letter is a formal written communication sent by an attorney to an insurance company or opposing party, outlining the facts of the case, the injuries sustained, the treatment received, and the amount of compensation demanded. The demand letter is a critical step in the personal injury claims process and typically initiates settlement negotiations. Most personal injury cases are resolved through negotiation after a demand letter is sent, without the need for a trial.
Settlement
A settlement is an agreement between the injured party and the at-fault party (or their insurance company) to resolve a personal injury claim for a specified amount of money, without going to trial. Settlements are the most common resolution for personal injury cases. Approximately 95% of personal injury cases settle before trial. Settlements provide certainty and faster resolution compared to trials but may result in lower compensation. The settlement amount, minus the contingency fee and case expenses, is the client's net recovery.
