You optimize your creation process: more method, fewer errors
Even if you have some knowledge of UX Design , it is likely that you have not thought of everything.
Have you created personas , defined a user journey, created an empathy map ?
Do you know the most effective methods for organizing your site's information architecture?
Do you know how to go about conducting user testing?
Are you an expert in analytics?
Do you have the necessary tools and software for each stage of your project?
In summary, are you 100% sure of what you are doing?
Using an agency means, above all, benefiting from proven methods that will save you precious time . But it is also a way to take a step back from your project: you certainly have a precise idea of the result you want to obtain, but does it really correspond to what users expect? A partnership with a UX Design agency prevents you from falling into the pitfall of vision and helps you stay focused on UX.
You get better results right out of the box
User experience is at the heart of the success of your site or application. Engagement and conversion rates are closely linked to visitor satisfaction . Who wants to buy or subscribe to a service when paytm database navigation is laborious and the journey poorly thought out?
Today, competition is such on the web that 68% of Internet users leave a site because of a bad experience and 44% of them will tell their friends about it. In short, for the sake of your turnover, it is in your best interest to entrust your UX Design to experts.

When do you need a UX Design agency?

At the beginning of your web project
Even before you launch your product to see if it meets its audience, optimize the UX as much as possible. Sometimes a bad user experience is the cause of the failure of a site or an application. You might think that it is your service that is not suitable, when the problem comes from elsewhere and can easily be solved with experienced partners .
When the results aren't there
Your turnover does not match your forecasts? The problem may come from UX Design . Even if your product is already launched, there is always time to improve it. By using an agency, you will quickly find the problems that prevent a good user experience .

UX Design Agency: How to Choose It?
To choose your UX Design agency well , you will first have to define your needs.
Some questions to ask yourself
What are your goals : reduce the shopping cart abandonment rate, encourage visitors to choose a particular subscription, optimize the steps of a sales funnel ?
Do you need a long-term partner who defines your strategy or a simple executor who will take care of the operational part of the project?
What are the deadlines to be met? Some agencies specialize in speed of execution.
What is your budget ?
What is your field of activity (be careful, however, with specialist agencies which sometimes show inflexibility following the creation of automatisms)?
What type of product do you offer: e-commerce , subscription service, SaaS, mobile application, professional software, social network, etc.?
Do you want to interact with the team in person or will video conferences do the trick?
The 5 steps to choosing your UX Design agency
> Step 1 - First, check if UX Design is the agency's core business and not an option added to a web development job, for example. Although it can be advantageous to contact an agency with varied skills that can take charge of your entire web project , it is important to ensure that UX is at the center of their concerns. To do this, you can get recommendations from those around you, but also rely on existing texts and articles on the agency's website: what exactly are they talking about?
> Step 2 - Once an initial selection has been made, browse the portfolio of each agency. Go and test the sites they have created and put yourself in the shoes of an average user. Did you enjoy the experience or did you detect many malfunctions ? Did you quickly find the information you were looking for? Preferably choose services that might interest you to see if the desire to buy comes to mind. Because let's remember here, UX Design is not limited to the visual and structural aspect of a site. It must also increase its commercial value.
