Optimal UI/UX design.

UI/UX design techniques can help to increase a website’s conversion rate by:

  • Focusing on what matters, such as providing clear and concise information and prioritizing key features.
  • Using intuitive navigation and white space to make the website more user-friendly.
  • Guiding users toward a conversion, such as making a purchase or signing up for a newsletter.

Add the right elements.

It’s important to include all the right elements in order to create an effective and engaging user experience. This includes a clear call to action, testimonials, effective copywriting and high-quality images + illustrations.

Properly combined, these components help to build trust and drive conversions, resulting in a more successful website overall.

Fast and reliable infrastructure.

High-quality code and a reliable backend platform are essential for the success of a website. These elements ensure that your site is efficient, fast, and secure, and can handle a large amount of traffic.

“Underscore did a fantastic job designing BHS’s new digital exhibit about the Lefferts family papers. Thanks to their vision, hard work, and creativity, we now have an elegant and usable site to feature our beautiful archival materials and to tell the story of one Brooklyn family’s history. I could not have imagined a better outcome.”

“Underscore is amazing. Not only did they re-design our entire site to make it more interactive and fluid; they also built a beautiful, flexible, simple-to-manage online store for us under a time crunch during our busy season.

Ever-helpful, patient, and willing to explain and re-explain, they worked closely with us to get just the right look and feel for everything, and it was all done in a matter of weeks. Anyone looking for design and/or website help would do well to contact them.”

“I came to Underscore with just a small, somewhat messy idea. They worked with me to develop it into a beautifully designed, easily navigable site.

Underscore’s approach to my project as a collaborator and partner made me feel like my project was as important to them as it was to me.”
