Speed is a customer problem first
People rarely wait to find out whether a slow page is worth it. They return to the results and open the next one, and you never learn it happened.
That is the honest case for speed: it protects enquiries you have already paid to attract, through advertising or through the search work that got you ranked.
What usually makes a business website slow
Oversized images are the most common cause by a wide margin — photographs uploaded straight from a camera or phone and resized in the browser rather than on the server.
After that: too many third-party scripts, chat widgets, tracking tags and font files; plugins or builders that load code for features the page does not use; and hosting that is cheap because it is shared with a great many other sites.
How it relates to search
Google uses page experience signals, including loading and stability measures, as part of how it ranks pages. They are one factor among many, not a substitute for relevance, and a fast page about the wrong topic will not rank.
The practical reading is this: speed rarely wins you a position on its own, but it removes a handicap, and the same fixes improve the experience for every visitor regardless of how they arrived.
What can be fixed without a rebuild
Compressing and correctly sizing images, serving modern image formats, removing scripts nobody uses, loading fonts sensibly and enabling caching are all maintenance tasks rather than redesign work.
A rebuild is only justified when the platform itself forces the weight — for example a theme that cannot load anything selectively. Establish which of the two you are dealing with before spending anything.
How to measure it honestly
Test the pages that matter commercially, not just the homepage, and test them on a phone connection rather than office broadband.
Record the numbers before you change anything. Without a baseline there is no way to tell whether the work helped, and speed improvements are easy to undo accidentally with the next plugin.
