The verdict in three sentences
A serious SEO content strategy for a B2B site costs 800 to 2,500 EUR/month in 2026, depending on article volume and competitive ambition. ROI is not immediate: expect 6 to 9 months before organic traffic delivers a steady lead flow. Well run, it drives a cost per lead of 20 to 60 EUR, three to five times cheaper than paid acquisition on the same audience.
What a content budget covers
A content budget is not just "writing articles." It spans keyword research, production, on-page optimization, internal linking and rank tracking. Here is the typical split of a monthly retainer.
| Line item | Share of budget | Indicative 2026 cost |
|---|---|---|
| Keyword research & strategy | 15 % | 150 to 400 EUR |
| Optimized writing (per article) | 50 % | 80 to 150 EUR/article |
| On-page & internal linking | 15 % | 120 to 350 EUR |
| Rank tracking & reporting | 10 % | 80 to 250 EUR |
| Link building (optional) | 10 % | 100 to 500 EUR |
A full semantic cluster (1 pillar page + 6 to 10 satellite articles) represents roughly 2 to 3 months of production at a steady pace.
Article volume and expected results
The crux of B2B SEO is consistency. Here are three commitment levels and their 12-month results, 2026 order of magnitude for a moderately competitive B2B niche in Dublin.
| Tier | Articles/month | Budget/month | Leads/month at 12 months |
|---|---|---|---|
| Kickstart | 4 | 800 to 1,200 EUR | 5 to 12 |
| Growth | 6 | 1,500 to 2,000 EUR | 12 to 25 |
| Domination | 8+ | 2,200 to 2,500 EUR | 25 to 50 |
To dominate a precise B2B niche, you generally need 40 to 60 quality articles published over 8 to 12 months. Below 4 articles/month, traffic momentum struggles to build.
Mini case study
Stephanie, marketing director at an HR software vendor in Dublin, picks the Growth tier at 1,800 EUR/month, i.e. 21,600 EUR/year. At 12 months her site generates 18 qualified leads/month. With a 12 % close rate and a 9,000 EUR average annual license, that's 2.16 new customers/month, roughly 233,000 EUR of new ARR over the year. Her cost per lead starts at 100 EUR then drops below 50 EUR once the article stock compounds. Break-even hits in month 7.

FAQ
How much does an SEO-optimized B2B blog article cost?
Between 80 and 150 EUR for a well-researched, optimized 800-to-1,200-word piece. Highly technical expert content (2,000+ words) can reach 250 EUR.
How long until ROI?
Expect 6 to 9 months for a steady lead flow. First rankings appear in month 2 or 3, but volume takes off around month 6 when internal linking kicks in.
What cost per lead should I target?
20 to 60 EUR once the strategy matures, versus 100 to 250 EUR on Google Ads for the same B2B keywords. SEO becomes profitable over time.
How many articles to dominate a niche?
Usually 40 to 60 quality articles over 8 to 12 months, structured as semantic clusters around 5 to 8 pillar pages. Consistency beats raw volume.
Do I need to pay for link building on top?
On competitive niches, yes: 100 to 500 EUR/month of quality links speeds up rankings. On a low-competition local Dublin niche, content alone is often enough.
