On May 28, 2020, Google introduced a new algorithm for calculating store rankings to display them at the top of search results. Now, AMP technology is not mandatory.
The key factor affecting the store ranking is the speed of rendering the largest visible content block — LCP.
Google has created an excellent tool for calculating and analyzing ranking issues — Measure.
To check the impact on ranking, you can use the calculator Lighthouse Scoring Calculator.
The example below shows what the store ranking would be if all metrics were set to maximum speed, and the LCP value was 4.7 seconds.
