The Importance of Async Ad Tags
It's been 6 years now that Google made page speed a ranking factor to determine its position in the SERP. The faster a page loads compared to its competitors, the higher it will end up in Google's search result list. If you have ads on your page, asynchronous loading will play a significant role to achieve that goal. Every time you load a JavaScript file on your page, it's important to understand how that will impact load speed. This article will show you with a real-life example why this is so important. Synchronous vs Asynchronous: What's the difference? Synchronous loading means in this context: one after another, or serial loading.

The browser literally does nothing but downloading that file, while it could have done th

Bot Filtering for Ads
GoogleBot crawls over the internet 24/7. While doing so, it also loads all ads it finds on your pages. You don't want to count impressions or clicks made those bots, crawlers and spiders.
