Google Ads vs Buying Personal Injury Leads: A Full ROI Comparison

Running your own Google Ads: what it takes

To run your own PI ads at scale, you need:

• A media buyer or agency who understands legal keywords, Google Search + Performance Max, and negative-keyword lists that filter out non-injury queries.
• A conversion-optimized landing page (or 20 of them, one per vertical + geo) with proper TCPA consent capture.
• Ad copy that clears Google's legal-vertical policy reviews.
• Meaningful budget — competitive PI keywords cost $80–$400 per click. You need $8,000–$25,000/month minimum to gather statistically-meaningful data.
• A tracking and attribution stack (GTM, GA4, CallRail, offline conversion imports back to Google) to prove which clicks turned into cases.
• Patience — the first 60–90 days are spent burning money on test data.

Buying leads: what it takes

• Sign a spec sheet with the vendor (geo, vertical, exclusivity tier, volume target).
• Connect your CRM to the vendor's webhook.
• Turn intake on.
• Get invoiced weekly for delivered leads.

No media buying skill needed. No landing pages. No creative. No policy risk. First lead in 48–72 hours.

The math: cost per signed case, head to head

In our client dataset, established firms running their own Google Ads (with a good agency) hit a cost-per-signed-case of $1,100–$1,800 for auto accident leads. Firms buying exclusive leads from a vendor hit $900–$1,400. Shared leads: $700–$1,500.

The buying-leads approach usually wins on CPSC in the first year because the vendor already has the campaign optimization done. In year 2+, mature in-house Google Ads programs can beat vendor pricing, but require ongoing investment in a media buyer.

When Google Ads is the right call

• You already have an experienced legal media buyer or agency on retainer.
• You want to own the customer relationship top-to-bottom (rebranding, remarketing, list building).
• You have budget to burn on 60–90 days of learning without expecting positive ROI.
• You have a large intake team that can handle intermittent volume as campaigns scale up and down.

When buying leads is the right call

• You want predictable case flow starting this week, not in Q2.
• You don't want to hire a media buyer or manage an agency.
• You want to test scaling into new geos without building out landing pages.
• You want a predictable per-lead cost rather than variable CPCs.

The hybrid approach most firms end up on

The majority of scaled PI firms end up doing both: a core Google Ads program for their home geo, plus vendor-purchased leads to scale into secondary geos and fill capacity when in-house campaigns dip. Start with buying leads to prove the intake operation, then layer in-house media buying once you understand what a good lead looks like. Book a call to talk through what mix makes sense for your firm.
