7 common mistakes in website development and how to avoid them in your business

In the digital age, your website isn't just a business card: it's your online marketer, your operations center, and often the first point of contact between your brand and a potential customer. Therefore, making mistakes during the development of your site can cost you dearly: fewer visits, fewer sales and a weakened professional image.

At Vexus, we have worked with many businesses that came to us after having bad experiences: slow sites, unprofessional designs, or structures that didn't convert. Based on that, we put together the 7 most common mistakes we've seen in website development and, most importantly, how you can avoid them so that your site works for your business.

‍

1. Not having clear objectives from the start

One of the most common mistakes is starting a project without a well-defined goal. Do you want to attract prospects? Selling products? Schedule appointments? Many sites fail because they are not aligned with a specific strategy.

Avoiding it is simple: before thinking about design, structure, or even content, define the main purpose of your site. Being clear about who you are addressing and what action you want them to take will allow you to make better decisions throughout development.

2. Ignore mobile optimization

More than 70% of web traffic comes from smartphones. If your site doesn't look good or doesn't work properly on mobile, you're losing a large part of the market. Even today we see poorly adapted sites, with buttons that are too small, hidden menus or images that don't load.

The solution is to work with a mobile-first or responsive approach from the start of the project. The site must adapt perfectly to different screen sizes, maintaining clear navigation and fast loading times. At Vexus, we always test on multiple real devices before launching any site.

3. Don't consider the charging speed

A slow site is a site that doesn't convert. If your page takes longer than 3 seconds to load, there's a good chance that users will leave before they see the full page. This not only affects your conversion, but also your ranking in Google.

To improve this, it is essential to optimize the size of the images, use modern formats such as WebP, avoid unnecessary plugins and choose a good server. Tools such as Google PageSpeed Insights or GTmetrix can help you identify what is slowing down your site.

‍

4. Leave technical and content SEO for later

A classic mistake is to focus solely on visual design and leave SEO as something “for later”. This is a big problem, because many important elements for positioning must be integrated right from the start of development.

We're talking about a good URL structure, correct use of headers (H1, H2, etc.), optimized titles and descriptions, alternative text in images, clear content focused on keywords, and adequate loading speed. At Vexus, we include these practices from the start in all projects.

5. Confusing or unintuitive navigation

If a person enters your site and doesn't understand where to go, what to do, or how to go back, they just leave. A poor user experience is one of the main reasons a site doesn't convert.

Avoid this by creating a clear structure, with a visible and simple menu, well-placed call-to-action buttons, and well-organized pages. The rule is simple: make everything easy. Think about a visitor's journey and make sure that each step brings them closer to the final goal.

6. Don't measure results or make adjustments

A website isn't something that is launched and forgotten. Another common mistake is not installing analysis tools or reviewing user behavior. Without data, you're making decisions blindly.

Integrate tools such as Google Analytics, Google Search Console or Hotjar to understand how your visitors navigate, which sections generate the most interest and where they go. With that data, you can continuously improve and achieve more conversions.

7. Improvise the content or leave it for last

Content is as important as design. Many businesses start with the visual design of the site and then improvise the texts. The problem is that without a good message, the design loses impact and the user doesn't understand what you offer.

From the start, define a clear value proposition and write with your ideal customer in mind. Texts must be persuasive, aimed at solving real problems and with clear calls to action. At Vexus, we always work on design and content as a single strategic block.
