Google Adword has an HTML snippet to track conversions:
It is composed of two parts:
- For other clients, an image tag.
As far as I can see, the image tag has some advantages:
- It works on all browsers.
- It is asynchronous.
- It's shorter to have only this version, compared to both this and the js version.
Any reason not to drop the
<noscript> tag and just use the image conversion snippet directly?
