In google search console, for my website, when the number of impressions increased (red trend in google search console), then the ranking in google search decreased (green trend in google search console aka "position"). Then, when the number of impressions decreased, then the ranking in google search console increased.
I thought that when my website links are displayed in google search at a better position, there should be more impressions because users don't click to visit subsequent google pages. They usually click on the links on the first page.
As you can see at the end of the trend, the impressions increased by at least 3000 and meanwhile the average position lowered by at least 20 and vice versa.
