Website run certain scripts that take a lot of executive list time to execute? Remove or optimize the unnecessary scripts in your website. A good example is a date picker. These are often quite complex components and you often only need them on your quote page or in your shopping cart process. It is then wise to split this off from your main script, so that that heavy script is only executed where it is really needed. These kinds of optimizations improve your FID scores.
Useful to do now? My advice is to check your Google Analytics: which pages receive the most SEO traffic and contribute to achieving your business goals? Then check the scores of these pages and tackle the pages that need it in the field of CLS, FID and LCP. And be sure to hire your web builder! The recommendations are in fact quite technical in nature. They undoubtedly know how to implement the recommendations. And you want that, because the faster you optimize.
