Q & A

  • What are Core Web Vitals and why are they important for a website?

    -Core Web Vitals are a set of metrics developed by Google to measure the quality of user experience on a website. They are important because they help ensure that a website provides a fast, responsive, and stable experience across all devices, which is critical for user satisfaction and search engine ranking.

  • What is the role of the Chrome Lighthouse tool in website optimization?

    -The Chrome Lighthouse tool is a hidden feature that generates a report on a website's performance, accessibility, best practices, SEO, and more. It provides suggestions on how to improve the website, making it faster and more user-friendly, which can enhance the overall user experience and SEO ranking.

  • What does SEO stand for and what is its significance in the context of website visibility?

    -SEO stands for Search Engine Optimization. It is significant because it involves optimizing a website to rank higher in search engine results, making the website more visible to users. This includes factors like page speed, content quality, and user experience.

  • How does Google determine which pages to show to users in search results?

    -Google determines which pages to show in search results based on various factors, including page speed, the quality of information presented, user experience, and Core Web Vitals. Pages that load faster and provide a better user experience are more likely to be ranked higher.

  • What is Cumulative Layout Shift (CLS) and why should it be minimized?

    -Cumulative Layout Shift (CLS) measures the visual stability of a page by quantifying the unexpected layout shifts that occur as the page loads. Minimizing CLS is important because layout shifts can negatively impact user experience by causing elements to move unexpectedly, which can lead to accidental clicks or a confusing interface.

  • What is the Largest Contentful Paint (LCP) and what is considered a good LCP score?

    -Largest Contentful Paint (LCP) measures the time it takes for the largest content element, such as an image or text block, to become visible on the page. A good LCP score is considered to be within 2.5 seconds, indicating that the most important content loads quickly, enhancing the user's perception of page speed.

  • What is First Input Delay (FID) and what is the recommended threshold for a good FID score?

    -First Input Delay (FID) measures the time from when a user first interacts with a page (e.g., clicks a button) to when the browser is actually able to process the input. The recommended threshold for a good FID score is less than 100 milliseconds, ensuring that the page responds quickly to user interactions.

  • How can setting explicit width and height attributes on images improve a website's layout stability?

    -Setting explicit width and height attributes on images helps improve layout stability by reserving the necessary space in the browser for each image as the page loads. Without these attributes, images may load later and cause the page layout to shift unexpectedly, leading to a poor user experience.

  • What is the purpose of meta tags and meta descriptions in SEO?

    -Meta tags and meta descriptions serve to provide additional information about a webpage to search engines and users. A well-crafted meta description can help increase click-through rates from search results by giving users a clear and concise summary of the page content, which can also indirectly influence SEO.

  • Why have meta keywords become less relevant in modern SEO practices?

    -Meta keywords have become less relevant in modern SEO practices because they were often abused by webmasters to manipulate search rankings. Search engines like Google have moved towards more sophisticated methods of understanding page content, such as natural language processing, reducing the reliance on meta keywords.

  • How can the responsiveness of a website be tested across different devices?

    -The responsiveness of a website can be tested using the developer tools in a browser, such as Chrome's DevTools. By selecting the 'Responsive' mode, developers can simulate how the website looks on various devices, from smartphones to tablets and desktops, ensuring a consistent user experience.
