User Experience
What is A/B testing?
A/B testing, also known as split testing or bucket testing, is a method of comparing two versions of a webpage or app to determine which one performs better. It's essentially an experiment where variants are shown to users at random, with statistical analysis used to evaluate performance against conversion goals. At Optimizely, they've conducted nearly 2 million tests across over 9,000 brands. The process involves creating a modified version of a page (ranging from a simple button change to a complete redesign), then randomly showing visitors either the original control or the variation. User engagement is measured and analyzed to determine whether changes had positive, negative, or neutral effects on behavior. This method allows teams to make data-driven improvements to user experiences and optimize conversion rates over time.

What is Largest Contentful Paint and how does it affect page performance?
Largest Contentful Paint (LCP) measures the time taken for the largest element on your page to load. For example, on a webpage, this is typically an image. A good LCP score is 2.5 seconds or less (shown in green), while 2.5-4 seconds needs improvement (orange), and anything above 4 seconds is poor (red). According to the experts, the best largest contentful element to have is text, as it loads fastest. To optimize LCP for images, you should resize dimensions, reduce file sizes to below 250kB, and use modern formats like AVIF or WebP.

Can you change the order of sections within your LinkedIn experience section?
Yes, you can change the order of positions within your LinkedIn experience section to highlight the most relevant roles. To do this, click the pencil icon on your experience section, then use the hamburger icons (drag handles) on the right side of each position to drag and drop them into your preferred order. This is particularly useful when preparing for job interviews and wanting to showcase specific experience that aligns with a potential position. The changes are automatically saved when you click the X to exit the editing mode.

How can e-commerce website owners improve loading speed to reduce abandonment rates?
E-commerce website owners can improve loading speed by implementing three key strategies. First, resize images to be appropriately sized rather than uploading enormous files while ensuring they remain large enough for users to view product details. Second, compress images using tools like Optimizilla to reduce file size without sacrificing quality. Third, convert images to faster file formats like WebP for optimal loading times. These techniques are crucial because 40% of shoppers will abandon e-commerce sites that take more than three seconds to load, making user experience optimization essential for reducing abandonment rates and improving conversions.

How is AI being used to enhance user experiences in creative agency work?
Creative agencies are leveraging AI to create compelling user experiences that enhance brand engagement. In Brian Tillman's work with Blackbird, an AI company doing cutting-edge research on narrative intelligence, they fully embraced AI-generated art to develop a bold visual identity where the interface feels interactive, with elements like glowing eyes that seem to watch users as they scroll. Rather than just implementing a vision, the focus is on creating the best possible experience using collective skills, resulting in websites that are engaging, tactile, and industry-defining. This approach effectively plants a flag for brands in competitive digital spaces.

How does empathy influence design thinking?
Empathy influences design thinking by allowing designers to observe the world through others' perspectives, putting aside preconceptions to understand users' needs at an emotional and psychological level. It fuels creativity that transforms into human-centered solutions by creating a bond between developers and users. David Kelley, IDEO's founder, explains design thinking as deeply understanding problems and realities of people you're designing for, meeting their needs in technologically feasible and strategically viable ways. Airbnb's success story demonstrates how empathy-driven design—improving listing photos—doubled their revenue and transformed their business.
