Tracking pixel

The endpoint returns a small 1×1 GIF image. You don’t need to use the JavaScript integration and can load this directly:

<img src="https://s.diduthink.com/count?p=/test">

Or you can build your own JavaScript integration if you want. Use the API if you want to send data from a script; /count is only intended to be loaded by the visitor’s browser.

The tracking pixel won’t allow recording the referrer or screen size, and may also increase the number of bot requests (we do our best to filter this out, but it’s hard to get all of them, since many spam scrapers and such disguise themselves as regular browsers).

Wrap in a <noscript> tag to use this only for people without JavaScript:

<script data-goatcounter="https://s.diduthink.com/count"
        async src="//s.diduthink.com/count.js"></script>
<noscript>
    <img src="https://s.diduthink.com/count?p=/test-noscript">
</noscript>

This accepts the following query parameters:

Query count.js Description
p path Page path or event name.
t title Page title.
r referrer Referrer value; usually the Referer header.
e event event; as boolean (true, false, 1, 0, on, off).
q - Query parameters, for getting campaigns.
s - screen size, as width,height,scale.
b - Flag this as a “bot request”; number.
rnd - Ignored; intended as a “cache buster”.

These parameters are guaranteed to be stable; any future incompatible changes will use a new endpoint. Building your own JavaScript integration should be safe, although you may need to modify it if new features get added.

rnd is useful as sometimes browsers and procies have their own opinion about what can or can’t be cached in spite of what the cache headers say.

The b accepts an integer constant from the zgo.at/isbot library and should be >=150. See the count.js source how to detect this. Current values:

  • 150 – Phantom headless browser.
  • 151 – Nightmare headless browser.
  • 152 – Selenium headless browser.
  • 153 – Generic WebDriver-based headless browser.
