Frequently asked questions
How much should a law firm spend on Facebook ads per month?
Law firms typically need $1,000–$2,500/month minimum to generate consistent consultation leads. High-value practice areas like personal injury can justify $3,000–$5,000+/month given the case value. The minimum viable budget for testing is $500–$1,000/month for 4–6 weeks.
What is a good cost per lead for lawyers on Facebook?
A good CPL for legal Facebook ads is $50–$150 for general practice areas. Personal injury and mass tort campaigns can tolerate $150–$300+ CPL given case values. Estate planning and family law should aim for $50–$100 CPL.
What audience should lawyers target on Facebook ads?
Targeting depends heavily on practice area. Family lawyers should target life events like 'recently divorced' or 'new relationship'. Estate planning attorneys should target 45–70 year olds with high income or homeowner status. Business lawyers should target small business owners and self-employed individuals. Always layer geographic targeting to your jurisdiction.
What Facebook ad format works best for law firms?
Lead Generation forms with a free consultation offer have the lowest CPL for most practice areas. Video testimonials from satisfied clients build the trust needed before someone shares sensitive legal issues. For retargeting website visitors, single image ads with a clear CTA outperform other formats.
Should law firms use Facebook ads or Google Ads?
Google Ads wins for urgent, high-intent searches ('DUI lawyer', 'personal injury attorney'). Facebook works better for less-urgent practice areas (estate planning, business law) and for building a retargeting pool of people who visited your site but didn't call. Many successful law firms run both: Google for immediate-need cases, Facebook for nurturing and less urgent matters.
How do I advertise legal services on Facebook without violating ad policies?
Avoid making specific outcome guarantees ('we'll win your case'). Don't use language suggesting outcomes are certain. For personal injury, avoid targeting based on sensitive health information. Focus ads on the process ('free consultation', '15+ years experience') rather than implied outcomes. Disclosures like 'results may vary' are good practice.
What is the best Facebook ad campaign objective for a law firm?
The Leads objective with a native lead form is best for most law firms — it captures consultation requests without requiring someone to visit your website. If you get 50+ monthly leads, switch to Conversions objective to let the algorithm optimize more effectively.
