Correctly setting your browser cache is very important!
Why is this important:
Setting up caching does not affect the speed of the first loading of the site for a new visitor, but the speed of the site during all subsequent visits and page transitions.
The files are saved in the user’s browser and when they are needed again, they are no longer downloaded from your server, but are immediately displayed, as they were downloaded earlier.
Many files on the site change very rarely and can be cached for a long time, and some files should not be cached at all.
What is included in the service:
I will set up a cache of static files of your resource for the time recommended by search engines!
If your site uses files from third-party resources (google-analytics, yandex metrika, widgets, pixels, etc.), then we cannot influence the cache of other resources!
IN PageSpeed Insights There is an item “Set rules for the effective use of cache for static objects”, the division of the cache of your files into third-party ones is clearly displayed there, you just need to uncheck the item “Show third-party resources”. After the correction, in the SUCCESSFUL AUDITS block there should be an inscription with a green label “Configuring rules for efficient use of cache for static objects - 0 resources found.” - it means everything is in order with your settings.
