小巴是自家公司網站 LogoMaker.com 的行銷人，這家公司會透過網站販售圖像標誌設計服務。有好幾位同事表示這個網站很難使用；小巴認為該網站若能讓使用者在瀏覽期間感到滿意，即可締造更出色的業績。 為了改善網站的使用者體驗，他應該專心處理哪兩個方面的工作？請選擇最合適的答案。

The correct answers are Navigation and Landing Pages. Navigation refers to how easily users can find their way around a website. If users find the website difficult to use, improving navigation will make it more intuitive and user-friendly, directly addressing the "hard to use" feedback. Landing pages are the specific pages users arrive at after clicking a link or advertisement. Optimizing these pages ensures they are relevant, engaging, and guide users toward the desired action (e.g., purchasing a logo design). A poor landing page experience can lead to high bounce rates and lost sales, even if the rest of the site is good. Images are important for aesthetics but don't directly address usability issues. Optimization is a broad term that encompasses many things, but navigation and landing pages are specific, actionable areas for improving user experience. Professional certification is irrelevant to website usability.
