It is believed that page loading speed is more important for SEO promotion on Google.
The search giant recently updated its GSC Internet Core Metrics report (which includes speed data), and has also begun to conduct related polls in SERPs .
In 2021, site load speed will officially be considered one of the user experience metrics in Google rankings.
There were no such loud statements from Yandex. However, they are promoting Turbo Pages on the pretext that a fast site is cool.
