PPC for UK law firms uses Google Ads and Microsoft Advertising to target high-intent legal searches — 'no win no fee solicitor', 'conveyancing solicitor near me', 'employment law advice UK'. Legal is one of the highest-CPC Google Ads categories in the UK (£15–£50+ per click for personal injury, £10–£30 for conveyancing), but also one of the highest conversion value categories — a personal injury client represents thousands of pounds in fees. SRA advertising rules apply to all law firm PPC.
Legal Google Ads requires both regulatory compliance (SRA advertising rules) and commercial precision (bidding on keywords where the CPA is justified by the case or instruction value). A personal injury firm can justify a £200 CPA for a case worth £3,000+ in fees; a conveyancing firm needs a lower CPA target for a lower average fee. Setting the right CPA target based on the actual value of the client acquired is the foundation of profitable legal PPC.
Legal PPC campaign structure
- Practice area campaigns — separate campaigns for each major practice area with specific ad copy and landing pages
- Location targeting — geo-targeting to the relevant catchment area for each practice
- Competitor keyword campaigns — bidding on competitor brand terms where permitted under SRA rules
- Call extension campaigns — legal enquiries often come via phone; call extensions are critical
- Time-of-day bidding — legal enquiries have strong weekday daytime patterns; adjust bids accordingly
- Negative keyword management — filtering out unqualified queries ('free legal advice', 'how to be a solicitor')
SRA Advertising Guidance requires that law firm advertising is accurate, honest, and not likely to mislead. Specific rules: claims about being 'best' or 'number one' require substantiation; testimonials from clients in current matters are prohibited; price advertising must comply with SRA transparency rules (certain fees must be published); and any financial claims must be accurate and verifiable. Google's own policies for legal advertising in the UK add additional requirements around certain legal service categories.
High legal CPCs are managed through: precise keyword targeting (exact match and phrase match rather than broad match to eliminate wasted spend), rigorous negative keyword management, landing page optimisation to improve conversion rate (so each expensive click converts more often), location restrictions (reducing CPC by targeting achievable geographic catchment areas rather than nationwide), and ad scheduling (focusing budget on the hours when legal enquiries convert most effectively). These techniques can reduce effective CPA by 30–50% compared to poorly configured campaigns.
