Patricia knew the firm was overpaying for Google Ads. She just didn't know by how much. The answer turned out to be: a lot.

The Situation

The account had been running on a single broad-match campaign for 3 years. It worked — cases came in — but nobody had examined whether the budget was being spent efficiently. A full search term audit revealed that 40% of spend was on queries like 'law school London', 'legal advice free chat', and 'employment lawyer' — none relevant to the firm's personal injury focus.

The Turning Point

A search term report showing £11,200/month spent on completely irrelevant queries was the evidence needed to justify a full restructure. The cost-per-case figure of £340 made the business case undeniable.

What We Did — And Why

We rebuilt the account from scratch: separate campaigns for each case type (road traffic, employer liability, clinical negligence), each with tightly themed ad groups, specific landing pages matching the query intent, and a negative keyword list of 340 terms. Bidding migrated from manual CPC to Target CPA using 18 months of conversion data. Ad copy was rewritten to emphasise 'no win, no fee' — the primary decision driver for personal injury claimants.

The Results

In Their Own Words

The ads weren't broken. The architecture was. With the right structure, the same budget works much harder.
