Google has changed its search algorithm in 2018 resulting that slower websites were pushed down the rankings.
WEBSITE STUCK, OR SLOW?
Google notes that slow mobile sites often serve as a hindrance to the user experience: "In fact, 53% of visits are abandoned if a mobile site takes more than three seconds to load, according to Google data from 2016."
A slow mobile site doesn’t just frustrate your customers, it can limit your business. In retail, we see that for every one-second delay in page load time, conversions can fall by up to 20%.
