Speculation Rules API

Recommended Posts

With the new Speculation rules API browsers can prerender pages. This can lead to ad impressions being requested and logged without users navigation to the page (and not seeing ads).

I think it would make sense to delay the logging to be delayed till after the prerenderingchange event to:

  • Avoid views never seen
  • Avoid reduction of CTR 


if (document.prerendering) {
      document.addEventListener("prerenderingchange", doSomething, { once: true, });
} else {
