Does a Website Really Pay Off for a Small Business? Let's Calculate the ROI

“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 of 2,000+ 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 than 3 seconds 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):

• 280 unique monthly users from Google (organic)
• 3.5% conversion rate (contact form)
• 9–10 new enquiries per month
• 60% 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.
