The verdict in three sentences
For a professional services firm, local SEO turns searches like "divorce lawyer Strasbourg" into qualified appointments. In 2026, a EUR 600-1,500/month engagement drives +40-70 % calls via an optimised Google Business Profile and local pages. With an average case worth EUR 2,000-8,000, a handful of new clients a year repays the whole year.
The levers of local SEO for a firm
Local SEO rests on three pillars: the GBP listing, local pages and reviews. Here is the typical investment.
| Lever | Content | 2026 order of magnitude |
|---|---|---|
| Google Business Profile | Optimisation, posts, categories | included in the retainer |
| Local pages | 15-30 pages per city/expertise | EUR 200-500/page (setup) |
| Client reviews | Collection strategy, replies | included |
| Expert content | Articles, legal/accounting FAQ | included |
| Monitoring & reporting | Rankings, calls, forms | included |
| Monthly retainer | EUR 600-1,500/month |
The ROI of a won case
In professional services, local SEO is judged by case count, not raw traffic.
| Metric | Before local SEO | After 6 months |
|---|---|---|
| Calls via GBP/month | 12 | 20 (+67 %) |
| Qualified forms/month | 5 | 9 |
| New cases/month | 2 | 4 |
| Average case value | EUR 2,000-8,000 | same |
| Time to first results | - | 3-6 months |
