优化谷歌广告代码，使其后加载，不影响博客加载速度。
将：<script async src="https://pagead2.googlesyndication.com/pagead/js/adsbygoogle.js"></script>
替换为：

<script>
window.onload = function() {
        setTimeout(function() {
                let script = document.createElement("script");
                script.setAttribute("async", "");
                script.src = "//pagead2.googlesyndication.com/pagead/js/adsbygoogle.js";
                document.body.appendChild(script);
        }, 2e3);
}
</script>

自动广告代码：<script data-ad-client="ca-pub-9880195064782685" async src="https://pagead2.googlesyndication.com/pagead/js/adsbygoogle.js"></script>

优化代码：

<script>
window.onload = function() {
        setTimeout(function() {
                let script = document.createElement("script");
                script.setAttribute("data-ad-client", "ca-pub-你的id");
                script.setAttribute("async", "");
                script.src = "//pagead2.googlesyndication.com/pagead/js/adsbygoogle.js?";
                document.body.appendChild(script);
        }, 0);
};
</script>
