The verdict in three sentences
Local B2B SEO turns buying-intent queries ("X supplier London", "Y provider Greater London") into recurring qualified leads with no cost per click. A realistic 2026 budget sits between 800 and 3,000 EUR/month, with first results within 3 to 6 months and a cost per lead that often drops below 120 EUR. The three levers that make the difference: optimised service pages, a flawless Google Business Profile, and targeted local link building.
What it costs and what it returns
Local SEO is not a one-off fixed cost: it is a monthly investment whose return compounds over time. Here are the 2026 orders of magnitude observed in the London market for a B2B SME.
| Local SEO service | Monthly budget 2026 (EUR) | Leads/month at 6 months | Estimated cost per lead |
|---|---|---|---|
| Starter (1 area, 5 pages) | 800 - 1,200 | 5 - 10 | 100 - 160 EUR |
| Growth (multi-area) | 1,500 - 2,200 | 12 - 20 | 90 - 140 EUR |
| Premium (national + local) | 2,500 - 3,000 | 20 - 25 | 100 - 150 EUR |
| SEO + expert content | 3,000 - 4,000 | 25 - 40 | 80 - 130 EUR |
Compare this with Google Ads on the same London B2B keywords, where CPC climbs fast and cost per lead stays structurally higher.
| Channel | Average cost per click | Cost per lead | Effect when budget stops |
|---|---|---|---|
| Google Ads B2B | 3 - 9 EUR | 180 - 400 EUR | Traffic drops to zero |
| Local SEO (year 1) | 0 EUR | 90 - 150 EUR | Traffic persists |
| Local SEO (year 2+) | 0 EUR | 40 - 80 EUR | Durable asset |
The three local SEO levers that convert
High-performing B2B local SEO relies on precise mechanics. Service pages (one page per service and per area) capture high-intent long-tail queries. An optimised Google Business Profile (categories, photos, reviews, weekly posts) generates a stream of calls and direct enquiries. Local link building (professional directories, regional press, partners) strengthens geographic authority.
| Lever | Concrete action | Time to impact |
|---|---|---|
| Service pages | 1 page per service + area | 2 - 4 months |
| Google Business | Reviews, photos, posts | 1 - 2 months |
| Local link building | 3 - 5 links/month | 3 - 6 months |
| Expert content | 2 articles/month | 4 - 8 months |

FAQ
How long before the first leads from local SEO?
Expect 3 to 6 months for significant results. Early ranking gains and calls via Google Business often appear from month 2, but stable volume arrives around month 6.
Is local SEO profitable versus Google Ads?
Yes, over time. Ads cost 180 to 400 EUR per B2B lead and stop dead without budget; SEO drops below 120 EUR in year 1, then 40 to 80 EUR in year 2 thanks to the accumulated asset.
Agency or freelancer?
For multi-service, multi-area B2B, a structured agency secures content, technical work and link building at once. A freelancer suits a single area and a tight budget (800 to 1,200 EUR/month).
Is the Google Business Profile enough?
No, but it is a pillar. It drives calls and directions, but without service pages or link building you quickly plateau on competitive queries.
