There's one thing I do for the social sharing plugins that I think everyone should do. Or, instead, I think it should be a default configuration within social sharing plugins, but it isn't - that thing is called asset cleanup. Both Social Warfare and Social Snap (and just about every social plugin) place their code on pages where social buttons are not present, triggering errors in Core Web Vitals and hurting your score. Asset cleanup is all about making sure your pages are only loading the necessary code and stripping plugin code from pages where they are not needed. Plugin files, scripts, hidden images; anything that doesn't need to be there should be removed from the page code. Stripping those assets from pages that don't need them can drastically improve your PageSpeed score. You can do this in two ways; with a plugin or by manually locating and dequeuing those elements in your fucntions.php file.
