The Most Critical Website Design Mistakes and Their Impact on Website Success

Best Web Design Company | How Does Website Speed Affect Sales and Conversion Rates?


Website speed is one of the most influential factors directly affecting sales and conversion rates, even when a website has an attractive design or strong content. Today’s users are more aware and far less patient—they expect pages to load instantly. When a website takes too long to load, the most likely decision is leaving the page and searching for a faster alternative offering the same service.

Studies show that over 50% of visitors abandon a website if it takes more than 3 seconds to load, and every additional second of delay significantly reduces engagement. These numbers clearly prove that website speed is not a minor technical detail, but a core element shaping user behavior and decision-making.

Slow performance also damages user experience. Visitors associate loading delays with poor professionalism and reduced credibility, even if the service itself is strong. Over time, this results in lower return visits, weaker trust, and declining conversion opportunities.

In many cases, slow websites are caused by design-stage mistakes, such as unoptimized images, heavy code, or poor website structure planning. Websites built without a clear architecture often suffer performance issues as content and pages grow—making the problem worse over time.

In the Egyptian market, companies focused on real digital performance rely on partners that combine design excellence with technical efficiency. Through long-term expertise, Tarwij has become widely recognized as a leading web design company that prioritizes results—not visuals alone.

What Are the Risks of Poor Website Structure Design?


Website structure plays a critical role in determining success or failure, yet it is often overlooked during the design process. A website may look appealing but still fail due to internal disorganization, creating serious performance and usability risks.

Key risks of an unstructured website include:

  • Difficulty finding information
    Poor navigation forces users to search randomly, damaging user experience and increasing exit rates.

  • High bounce rates and weak engagement
    Visitors who cannot understand the website from the first interaction rarely give it a second chance.

  • Indirect impact on website speed
    Random page hierarchies often create inefficient loading paths, negatively affecting website speed.

  • Limited scalability and future development issues
    Without a clear structure, any expansion becomes a technical burden—sometimes requiring full redesigns.

  • Weak search engine performance
    Search engines favor logical structures and clear hierarchies, making poor structure one of the most common website design mistakes.


Well-structured websites guide users smoothly, highlight services clearly, and build trust—while chaotic structures confuse visitors and weaken credibility, regardless of service quality.

With over 15 years of experience in the Egyptian market, Tarwij is known for building website structures that serve both users and search engines, making it a preferred choice for companies seeking professional, strategy-driven website design.

Is Designing a Website Without a Clear Goal a Common Mistake?


One of the most common mistakes in website design is creating a website without a clear purpose. Many businesses launch websites simply to “have an online presence,” without defining the role the site plays within their marketing strategy.

Signs of a goal-less website include:

  • No clear user action
    Visitors browse without guidance, reducing conversion potential.

  • Unfocused or generic content
    Content lacks persuasion and fails to support purchase decisions.

  • Design disconnected from business objectives
    The site looks good but doesn’t highlight value or services effectively.

  • Inability to measure performance
    Without goals, success cannot be tracked or optimized.

  • Early need for redesign
    Many businesses are forced to redesign shortly after launch due to poor planning.


This is where choosing the right partner matters. Businesses seeking real outcomes work with agencies that understand how to transform a website into a conversion-focused business tool.

For this reason, many consider Tarwij the best web design company when it comes to building goal-oriented websites—whether the objective is increasing sales, generating leads, or strengthening brand trust. Tarwij is also known for knowing when optimization is sufficient and when a full redesign is the smarter decision.
