Web Design Mistakes

• Having web design done by a freelancer, a relative or a family friend, rather than a corporate web design company.
• Instead of getting results by paying a relatively high fee once, not getting any results by paying low fees over and over.
• Creating web applications not from the customer's perspective and taking their needs and expectations into consideration, but from their own eyes and subjective values.
• Not knowing the logic of search engines and having a website built by only paying attention to visual beauty.
• Not paying attention to the interactive and functional website. 
• Establishing a site to say "I have a site too" without analyzing the target audience and purposes
• Choosing cheap and slow hosting.
• Not paying attention to registering the domain name in one's name when purchasing the domain
• Not paying attention to Internet Advertising

Content and Design Errors

• Users should be able to understand the content of your site in a very short time.
• An illegible, fancy or very low font should not be used.
• Excessive use of media such as Flash elements, videos and music can bore your visitors as it affects the loading of the site.
• Make sure that contact information is added to the website. Otherwise, there may be problems with feedback
• It should have a clear  site navigation. Let visitors easily find what they want.
• Make sure the site displays the same in all browsers
• Put functional links under the designed pages, this is also beneficial for search engines.
• If you are displaying your products on your website, place your products in the correct category and subcategories in a way that everyone can understand
• Optimization for search engines may generally be eliminated due to reasons such as grammatical and spelling errors, plural expressions, underscores and hyphens. If the search engine bots on the site do not achieve their purpose, this is very bad in terms of indexing.
• Visitors who enter your website hate the horizontal scroll bar. Horizontal scroll bars may appear depending on users' monitor resolutions. Horizontal scroll bars appearing on low-resolution pages may cause visitors to be unable to fully view the site.
• The blocks used in the design are very boring and hinder reading the content, causing users to leave the site quickly.
• Everyone hates pop-ups that open for advertising or for no reason.
Users react negatively when websites ask for email addresses. No one wants to give this information without a guarantee, thinking that it will come back as spam.
• When websites request e-mail addresses from their visitors, they must explain the privacy policy to the users andThey must undertake that they will not be given to third parties for advertising. Otherwise, no one wants to give their personal information without a guarantee, thinking that it will return as spam
• If the domain name is too long, this is a negative situation for visitors. In long site names, if the user types the name of the site and it does not appear, 80% of them will not try it a second time. That's why a short and understandable domain is important for site visitors.
