Law Firm PPC: Google Ads Strategy for Legal Services

By Harrison Hill· Founder & Chief Strategist

Legal PPC is among the most expensive in any sector. Personal injury keywords can exceed £30 per click, commercial litigation £20+, and even conveyancing clicks run £5-10 in competitive areas. Without tight strategy, a £3,000 monthly budget evaporates in days with nothing to show for it.

At iNDEXHILL, we manage paid media campaigns for professional services firms. This guide covers how to structure legal PPC campaigns that generate qualified enquiries at sustainable cost per acquisition.

Campaign Architecture for Law Firms

Legal PPC requires granular campaign structure. Mixing practice areas in a single campaign leads to budget being consumed by the highest-CPC terms while lower-cost, high-value areas get nothing.

Recommended Campaign Structure

  • Brand campaign — Firm name, partner names, branded terms
  • Conveyancing campaign — Lower CPC, high volume, strong ROI
  • Family law campaign — Moderate CPC, emotional journey, needs specific messaging
  • Employment law campaign — Split employee-side vs employer-side
  • Personal injury campaign — Highest CPCs, needs strict qualification
  • Commercial/corporate campaign — High case values, lower volume

Why Granular Structure Matters

Each practice area has different CPCs, conversion rates, and case values. Separate campaigns allow independent budget control, bid strategies, and performance measurement.

Law Firm PPC Budget by Practice Area

Recommended budget split for a multi-practice firm

  • Conveyancing
  • Family Law
  • Employment Law
  • Brand Protection
  • Commercial / Niche

Conveyancing takes the largest share due to high volume and strong ROI despite lower CPCs. Brand protection at 15% prevents competitors from siphoning branded search traffic. Personal injury is excluded here due to its exceptionally high CPCs requiring a dedicated, larger budget.

Frequently Asked Questions

Minimum £2,000-3,000/month for a single practice area in a mid-size city. Competitive areas (personal injury, commercial law in London) may need £5,000-10,000+ monthly. Start with your highest-value practice area, prove ROI, then expand.

Both serve different purposes. PPC provides immediate visibility for competitive terms while SEO builds. Long-term, SEO delivers lower cost-per-acquisition. Short-term, PPC generates enquiries from day one. Most successful firms run both simultaneously.

Focus on long-tail, location-specific terms rather than broad practice area terms. 'Employment tribunal solicitor Birmingham' costs less and converts better than 'Employment solicitor'. Use exact match for high-CPC terms and build comprehensive negative keyword lists.

Yes, and it's highly effective. Someone who visited your divorce page but didn't enquire is a warm lead. Remarketing keeps your firm visible during their consideration period. Ensure ad content remains compliant and doesn't reference specific legal matters.
