Many thanks for your review @saulverez! Great to hear that you’re using it for your current role.
In relation to the performance mention I’d be happy to work with you to check for any possible causes if you’re experience any issues with your site. Site Kit is primarily a wp-admin operated plugin, so any performance impact you’ve determined may be as a result of any features you’ve added via tag manager, your current AdSense configuration or a third party related conflict. If you do wish for me to check this wish you feel free to open a support topic.
Thanks again for your review, and best of luck with your Site Kit enabled site.
