Ans: The importance of these metrics varies depending on what users are doing on your website. If they only intend to read content and not interact with anything, then FMP and FCP would be the best metrics to look at. However, if people are landing on your page and interacting with things immediately, then TTI and FCI would be better metrics. Splitt and Mueller from Google recommend site owners to look at multiple sets of data and find areas of improvement according to what’s important for the audience.
