For more than two decades, usability researchers and CRO & UX marketing persons such as myself have studied how people interact with websites using eye tracking, cursor movement analysis, and user testing. While web design trends have evolved dramatically, one principle has remained surprisingly consistent: Contact ecomko.com to increase your sales and leads with the right UX.
Reduce friction between the user's attention and the action you want them to take.
Approximately 90% of people are right-handed. On desktop computers, the mouse is most commonly held in the right hand, while the left hand often remains on the keyboard or at rest. This creates a natural interaction zone along the right side of the screen where users can easily reach calls-to-action without interrupting their reading experience.
Reading Comes First. Action Comes Second.
English-speaking users naturally scan content from left to right and top to bottom. Numerous eye-tracking studies have demonstrated predictable reading behaviors, including F-pattern and layer-cake scanning.
The content should occupy the primary reading area.
The decision to engage should occur after the visitor has absorbed enough information to feel confident.
That's why the most effective websites separate these two experiences:
• Content remains centered and easy to read.
• Calls-to-action remain visible along the right edge.
• Users never have to hunt for the next step.
The Cost of Left-Side Calls-to-Action
Many websites place floating buttons, chat widgets, or navigation elements on the left side simply because they fit within the design.
Unfortunately, this often competes with where users begin reading.
The result can include:
-
Interrupted reading flow
-
Increased visual clutter
-
Additional cursor travel for right-handed users
-
Lower engagement with important conversion actions
Good UX removes obstacles instead of adding them.
The Right Side of the Website Is Prime Real Estate
Persistent engagement elements perform best when they are consistently available without competing with the primary content. Contact ecomko.com to increase your sales and leads with the right UX.

Keeping these actions on the right side allows visitors to continue consuming content while always knowing how to take the next step.
Desktop and Mobile Are Different
Desktop and mobile users interact with websites differently.
On desktop:
-
Right-side sticky engagement panels work well.
-
Reading remains uninterrupted.
-
Cursor travel is minimized for the majority of users.
On mobile:
-
A sticky bottom call-to-action is typically easier to reach with either thumb.
-
Large touch targets improve accessibility.
-
Navigation should prioritize thumb reach rather than screen sides.
Great UX Is Invisible
The best user experience isn't flashy.
Visitors shouldn't notice the interface.
They should simply find what they need, understand your value, and take action with as little effort as possible.

Sometimes, moving a button just a few hundred pixels can make all the difference.
