The verdict in three sentences
A lead-focused B2B website redesign budgets in 2026 Dublin between 10,000 and 25,000 EUR depending on scope. The question is not "what does it cost" but "what does it return": a conversion uplift of +0.5 to 2 points on existing traffic transforms the maths. Build a business case before you go to your board: project cost, cost per lead before/after, return on investment at 12 months.
The budget by scope
A B2B redesign is not a facelift: it is a conversion machine. Here are the 2026 envelopes by ambition, on the Dublin market.
| Scope | 2026 price (EUR) | Main lever | Timeline |
|---|---|---|---|
| Targeted redesign | 10,000 – 14,000 | UX + conversion funnel | 6 – 8 wks |
| Full redesign | 14,000 – 20,000 | + content + technical SEO | 8 – 10 wks |
| Redesign + acquisition | 20,000 – 25,000 | + landing pages + tracking | 10 – 12 wks |
| Recurring SEO | 500 – 2,500 /month | Content, link building | Ongoing |
| A/B testing & CRO | 1,000 – 3,000 /month | Continuous optimisation | Ongoing |
The line that returns most is not design but conversion funnel optimisation: forms, calls to action, trust signals. That is where a 1-point conversion gain is won.
The ROI calculation
A B2B business case rests on three numbers: traffic, conversion rate, value of a lead. Here is a costed model for a 16,000 EUR redesign.
| Metric | Before redesign | After redesign | Effect |
|---|---|---|---|
| Visitors/month | 3,000 | 3,000 | Stable |
| Conversion rate | 1.5 % | 2.7 % | +1.2 pt |
| Leads/month | 45 | 81 | +36 |
| Cost per lead | 55 EUR | 31 EUR | -44 % |
| Leads gained/year | — | +432 | ROI |
At constant traffic, moving from 1.5 % to 2.7 % conversion generates 36 extra leads a month. If 20 % convert into clients at 4,000 EUR margin each, that is ~345,000 EUR of additional annual margin: the redesign pays back in weeks.
Mini case study
Sarah is CFO of a 60-person industrial SME in Dublin. She must get sign-off on a 16,000 EUR redesign plus SEO at 1,200 EUR/month. She presents the business case: total year-1 cost = 16,000 + 14,400 = 30,400 EUR. Estimated gain: +36 leads/month, of which 7 extra clients/year at 4,000 EUR margin = 28,000 EUR in year one, then 336,000 EUR at cruising speed in year two. The board approves, noting cost per lead divided by 1.8. She ties the SEO spend to a 6-month traffic target.

FAQ
How do I justify a B2B redesign to my board?
With a costed business case: current traffic, conversion rate, value of a lead. A 1-point conversion gain on existing traffic is often enough to pay back the project in under a year.
What conversion uplift can I expect from a redesign?
In 2026, a serious B2B redesign targets +0.5 to 2 points of conversion depending on the current site. A dated, poorly optimised site offers the greatest upside.
Is recurring SEO essential?
To generate durable traffic, yes. Allow 500 to 2,500 EUR/month in 2026 depending on ambition. Without regular content, organic traffic stalls then declines against competitors.
How much does a B2B lead cost via an optimised site?
It depends on the sector, but a successful redesign often cuts cost per lead by 30 to 45 %. In our model it drops from 55 to 31 EUR thanks to a better conversion rate.
Should I invest in A/B testing?
Once traffic exceeds a few thousand visitors a month, yes. A CRO budget of 1,000 to 3,000 EUR/month enables continuous optimisation and locks in the conversion gain over time.
