B2B SaaS is different digital marketing from ecommerce. The value of a deal is €5,000–50,000 a year, the sales cycle is 30–120 days and 3–7 people take part in the decision. That shapes everything.
In brief
- LinkedIn is B2B SaaS’s most effective channel.
- Content marketing and SEO produce the most over the long term.
- A realistic media budget: €3,000–15,000/month for a SaaS company.
- CAC target: 30–40 % of the annual commitment.
Why digital marketing matters in this industry
Customers in this industry behave differently through the buying process than others do. That shapes both the choice of channel and the message. Without an understanding of the industry, advertising usually eats money without producing results.
The best channels in this industry

- LinkedIn Ads — reaching the decision-makers.
- Google Ads — competitor terms and intent.
- Content marketing: guides, case studies, benchmarks.
- SEO and technical content: use-case and comparison pages.
- Webinars and events — raising lead quality.
A realistic monthly budget
- Early-stage SaaS: €3,000–5,000/month of media + €1,500–2,500/month of management.
- Growth-stage SaaS: €5,000–15,000/month of media + €2,500–5,000/month of management.
- Enterprise SaaS — €15,000+/month of media across several channels.
The most common mistakes in this industry

- Measuring the number of leads rather than their quality. 100 bad leads ≠ 10 good ones.
- Not connecting the advertising to the CRM, so the sales team does not know where a lead came from.
- No nurturing — only 10 % of leads are ready to buy immediately.
- Writing all the competitor comparisons yourself instead of using analysts’ data.

Frequently asked questions
What is a realistic CAC in B2B SaaS?
The general guideline: CAC should be 30–40 % of the annual commitment (ARR). If the annual commitment is €5,000, a CAC of €1,500–2,000 is fine.
How quickly will I see results?
The first leads in 2–4 weeks. A settled flow of leads in 3–6 months. Closed deals 2–6 months after that.
Does Google Ads work in B2B SaaS?
It works, but not alone. The combination of LinkedIn plus Google Ads plus content works best.
