According to Baymard Institute research, the average abandonment rate on commercial websites is over 70%. This means more than two-thirds of visitors leave without taking any target action. The reason isn't always traffic quality. Most often, the problem is the website itself. Here are the 10 most common mistakes.

1. Slow loading speed

If your site takes longer than 3 seconds to load, you're losing 53% of mobile visitors before they see anything. Google uses Core Web Vitals as a ranking factor. Check your site through PageSpeed Insights and bring LCP scores to the "green zone."

2. No mobile version

In 2026, over 65% of web traffic is mobile. If your site is uncomfortable to browse on a smartphone, you're pushing away most potential clients. Mobile-first isn't a trend — it's a baseline requirement.

3. Confusing navigation

Users should find needed information in 3 clicks or fewer. If the menu is overloaded, categories are illogical, and search doesn't work — people will go to competitors who make it simpler.

4. No clear CTAs

CTA (Call to Action) — buttons or links leading to the target action: order, call, submit a request. If a visitor doesn't know what to do next — they do nothing. Every key page should have one main CTA.

5. Poor contact forms

A form with 10+ fields, no autocomplete, no validation, and unclear errors is a conversion trap. Cut the form to the minimum: name and phone or email. Clarify the rest in person.

6. No SSL certificate

A site without HTTPS shows a "Not Secure" warning in Chrome. Users don't trust such sites — especially if they need to enter personal data. SSL starts free (Let's Encrypt) and is mandatory in 2026.

7. SEO ignored from day one

Many clients think: "First we'll launch the site, then we'll do SEO." But fixing URL architecture, heading structure, and meta tags after launch is far more expensive than doing it right from the start. SEO needs to be built into the structure during development.

8. No analytics

Without Google Analytics 4 and Search Console, you don't know where users come from, which pages are popular, or where they drop off. Without data, improving conversion is impossible — it's just shooting in the dark.

9. Weak or absent content

"We are a young dynamic company offering a wide range of services" — such text sells nothing and distinguishes you from nothing. Quality content answers the client's question, removes objections, and explains the specific value of your offer.

10. No social proof

Reviews, case studies, client logos, certificates, real team photos — these transform skeptics into buyers. According to Nielsen, 92% of consumers trust recommendations from acquaintances, and 70% trust online reviews from strangers. If your site lacks these, you're underusing the most powerful persuasion tool available.

What to do next

Go through this list and honestly assess your website. If you found 3 or more problems — it's a signal for a serious audit or rebuild. The cost of quality redesign pays off through conversion growth within 2–3 months.
