Your site should not only be
fast in numbers, it should also feel fast for the people using
it! Your content needs to be on screen as fast as possible! Not all of
your users, probably not even most of them, will have access to
lightning-fast 4G connections or the newest phones. You need them to have
an awesome experience on your site as well! Bonus: Google will reward
you, as page speed is a ranking factor. Google Lighthouse is a new tool
that looks at site speed from a more practical approach, by putting user
experience front and center!
