Creating a website is not just a matter of beautiful design. It is a complex process in which it is important to take into account hundreds of nuances. Mistakes at the start can lead to loss of traffic, customers and money. In this article we will tell you about the most common, but often unnoticeable mistakes in website development, and most importantly - how to avoid them.
Common mistakes in planning and design
Planning mistakes are the cause of most website problems.
In the preparation phase, it is important:
- Unclear project objective
Without a clearly articulated purpose and understanding of the site's goals, you can stray away from the needs of your audience. The site should respond to your customers' needs and solve their problems. - Ignoring the portrait of the target audience
Designing without taking into account the age category and interests of potential customers leads to a site without visitors and conversions. - Design overload
Too many details, animations and complex effects distract the user. Instead of a modern website, you get a heavy page that you want to leave as soon as possible. - Poor mobile adaptation
In 2025, more than 70% users are accessing websites from mobile devices. If a website doesn't display well on smartphones, you lose most of your traffic.
To avoid these mistakes, you need to clearly define the site's objectives at the start, map out user scenarios, and trust professionals who know the current UX/UI trends.
Problems with SEO and contentthat are being forgotten
Even the most beautiful website will be useless without proper SEO and the right content.
- Absence of SEO optimisations in the development of
Many companies make a website, and SEO is remembered later. This is a big mistake. Even at the design stage, it is important to take into account the structure of the site, the logic of URLs, the speed of page loading, micropagination and other SEO factors. - Poor quality texts
Content is the foundation of a website. Often, content is left "for later" or assigned to people with no SEO copywriting experience. As a result, the relevance of pages suffers, and the site loses its position in the search engine results. - Mistakes in technical SEO
Lack of correct meta tags, incorrect redirects, duplicate pages and other technical deficiencies greatly hinder promotion. - No elaborate structure of the site
If the navigation structure is confusing, the page becomes inconvenient for both users and search engine robots. This worsens behavioural factors and reduces the site's ranking.
The solution is simple: you need develop an SEO and content plan before the project starts, not after.
How to test a website before launch
Even the most professionally made website needs a thorough review before publishing.
What to look out for:
- Checking on all devices
Check how the site displays on different smartphones, tablets, laptops and monitors. - Download speed test
Use tools like Google PageSpeed Insights to test your speed. Optimise images, connect CDNs, minimise scripts. - Audit of SEO indicators
Make sure all pages are indexable, meta tags are spelled correctly, and sitemap and robots.txt are set up. - Checking all forms and buttons
Test form submission, correctness of the shopping basket, newsletter subscription and feedback. - Analytics and tracking
Install Google Analytics, Yandex.Metrics or other analytics systems before launch to collect user behaviour data right away. - Content testing
Check texts for literacy, keyword relevance and consistency with brand intonation.
Proper pre-launch testing - the key to a successful project start-up and risk minimisation.
