If an online web form is difficult to navigate around, then it wouldn’t get the desired results for you. The form should be easy to circumnavigate around, and shouldn’t make your customers fret over it. A bad form sends the wrong impression and may make you lose out on customers rather than building on more. 
Some of the common web form mistakes made by developers are: 

Input Validation 
Input Validation is extremely essential in the design of a web form. The main purpose of input validation is to catch a basic mistake and to inform visitors about it, so that they can duly rectify it. However, it can turn out to be a real disturbance if the mistakes aren’t caught properly, which is why this feature tends to be confusing more than helpful. 

These mistakes can be avoided by ensuring the following features: 
•    Don’t try and be too strict on the forms by cutting every minor mistake. Customers might eventually lose interest in filling the form if they get stuck up on every answer. 
•    Give Examples: You can lead by giving a few examples of what you want from them. If you want the mobile number to be posted in a particular manner, then post an example of the format on the form, so that the respondent can understand what is required. 
•    Report Errors Early: Instead of telling respondents that they made a mistake right at the end of the process, tell them if they are making any errors early on. This will give the customers an indication of what they can expect, and how they should proceed with the process.

Copying Paper Form 
While in paper forms everything is cramped up to ensure that not much paper is wasted, form creators on software tools don’t have to worry about this aspect. However, some form creators don’t get a hang of what is required over here and end up following the same paper mentality in their online forms as well. This paper mentality may make way for unaesthetic and unrealistic forms that may not look attractive to fill up. Customers don’t want the same old boring templates, so give them something that is new and interesting. Innovative and creative ideas in form making can be useful, as they get you the appreciation and the response that you would want from your form. 

Fancy Components 
Always ask yourself a few questions before you add fancy components to the form that you are making. While some form-creators take no question into perspective while creating forms, it is necessary that you take some of these questions into consideration: 

•    Does the new fancy component work with older versions of browsers? 
•    Does it work on mobile devices, especially old ones? 
•    Does it perform a seamless experience across platforms? 
•    Does it work similarly well in all languages? 
•    Will it be the same next year?
