“I’ve run my business for 15 years without a website and it works just fine” — I hear this regularly from owners of service, manufacturing and retail businesses. And they’re right: you can run a business without a website. The question is: what does that cost you?
Data That Changes the Perspective
Before we get to the numbers, a few market facts:
70%of B2B buyers check a supplier’s website before first contact (Demand Gen Report, 2024). If you don’t have one — some of them will never call.-4.42%conversion for every additional second of page load time (Portent, study of2,000+sites). A slow site = fewer enquiries, even if you have traffic.88%of users won’t return to a website after a bad experience (Adobe, 2023). An old, broken site can be worse than having no site at all.53%of mobile traffic abandons a site that takes more than3seconds to load (Google, 2024).
ROI Example: HVAC Installation Company, 8 Employees
Let’s take a concrete case. An HVAC installation company (air conditioning, ventilation) in Wrocław, 8 employees, revenue 1.8 million PLN annually. Until now, clients came through referrals and the Oferteo platform.
Investment: business website in the Business package — 4,800 PLN (incl. VAT). Blog with 12 SEO articles (6,000 PLN, written internally by a technician). Total: 4,800 PLN one-time.
Results after 12 months (data from Google Analytics and CRM):
280unique monthly users from Google (organic)3.5%conversion rate (contact form)9–10new enquiries per month60%of enquiries convert to jobs- Average job value:
3,200 PLN - Monthly revenue from organic channel:
~18,000 PLN
Year 1 ROI:
Annual organic revenue: 18,000 PLN × 12 = 216,000 PLN
Investment cost: 4,800 PLN
ROI = (216,000 − 4,800) / 4,800 × 100% = 4,400%This is obviously a simplified model — some enquiries would have arrived via referrals anyway. But even with 10% attribution to the website — ROI of 440% is a result every CFO approves.
What Destroys Website ROI?
The website alone doesn’t generate traffic. Three factors that most commonly undermine results:
1. Slow Loading
LCP (Largest Contentful Paint) above 2.5s is the first conversion killer. Google’s algorithm penalises slow sites in rankings — you get less traffic. Users who do land on it leave faster. 1 second of delay = 7% fewer conversions (Akamai, 2023).
Verify Lighthouse Performance before accepting the deliverable. If the score is below 80 — the site is technically broken.
2. No Technical SEO
A site without schema.org, without sitemap.xml, without canonical URLs, without meta descriptions is a site invisible to Google’s crawlers. You can have beautiful design and 0 organic traffic after 12 months.
3. No CTA (Call to Action)
Many business owners think putting a phone number in the footer is enough. Eye-tracking research shows that 70% of users never reach the footer. The CTA must be visible above the fold, on every page, in the form.
When Is a Website NOT Enough?
ROI materialises when:
- your industry is searched in Google (air conditioning installation, lawyer in Wrocław, office cleaning in Kraków);
- you have something to say (blog, case studies, testimonials);
- the site is technically sound (fast, responsive, with CTAs).
If you operate exclusively B2B in a closed market (tenders, long-term contracts, internal referrals) — website ROI may be low. But even then: 70% of B2B buyers check the website before contact. No site = no credibility.
