| # Cumulative Layout Shift Changes in Chrome 97 |
| |
| ### BFCache rollout causes big CLS improvements across the web |
| |
| Chrome broadly rolled out the [BFCache](https://web.dev/bfcache) in January 2022. |
| |
| ## How does this affect a site's metrics? |
| |
| For page loads which are restored from BFCache instead of being fully loaded on |
| a back/forward navigation, any layout shifts which occur during page load are |
| skipped. This can result in big improvements for sites with layout shifts during |
| page load. |
| |
| ## When were users affected? |
| |
| The BFCache was widely rolled out in January 2022. |
| The CrUX report included this update starting with the January 2022 report. |
