Set up Google Analytics

This is for tracking how many people visit your website and where they're from.

Actually you don't need Google Analytics, but you can just use any analytics plugin here https://wordpress.org/plugins/search/analytics/

Get your Google Tag. About Google Tag: https://developers.google.com/tag-platform/gtagjs

Insert this into "Lay Options" → "Custom <head> content"

Replace "GA_TRACKING_ID" with your tracking ID which looks like: "UA-X13XXX0XX-1"

<!-- Global site tag (gtag.js) - Google Analytics -->
<script async src="https://www.googletagmanager.com/gtag/js?id=GA_TRACKING_ID"></script>
<script>
    window.dataLayer = window.dataLayer || [];
    function gtag(){dataLayer.push(arguments);}
    gtag('js', new Date());
    gtag('config', 'GA_TRACKING_ID', {
        send_page_view: false
    });
</script>
<script>
    window.laytheme.on('newpageshown', function(){
        if( typeof gtag != 'undefined' ) {
            gtag('event', 'page_view', {
                page_title: document.title,
                page_location: window.location.href,
                page_path: window.location.pathname,
                send_to: 'GA_TRACKING_ID'
            })
        }
    })
</script>

Sending the "page_view" event manually when Lay Theme's "newpageshown" event is triggered makes sure Google gets all page views.
