How to use

// In your gatsby-config.js
module.exports = {
  plugins: [
      resolve: `gatsby-plugin-google-analytics`,
      options: {
        // Puts tracking script in the head instead of the body
        head: false,
        // Setting this parameter is optional
        anonymize: true,
        // Setting this parameter is also optional
        respectDNT: true,
        // Avoids sending pageview hits from custom paths
        exclude: ["/preview/**", "/do-not-track/me/too/"],
        // Enables Google Optimize using your container Id
        // Enables Google Optimize Experiment ID
        experimentId: "YOUR_GOOGLE_EXPERIMENT_ID",
        // Set Variation ID. 0 for original 1,2,3....
        // Any additional create only fields (optional)
        sampleRate: 5,
        siteSpeedSampleRate: 10,
        cookieDomain: "",

See below for the complete list of Create Only Fields.

To make it easy to track clicks on outbound links in Google Analytics, the plugin provides a component.

To use it, simply import it and use it like you would the <a> element e.g.

import React
import { OutboundLink } from 'gatsby-plugin-google-analytics'

export default () => {

The “anonymize” option

Some countries (such as Germany) require you to use the _anonymizeIP function for Google Analytics. Otherwise you are not allowed to use it. The option adds two blocks to the code:

function gaOptout(){document.cookie=disableStr+'=true; expires=Thu, 31 Dec 2099 23:59:59 UTC;path=/',window[disableStr]=!0}var gaProperty='UA-XXXXXXXX-X',disableStr='ga-disable-'+gaProperty;document.cookie.indexOf(disableStr+'=true')>-1&&(window[disableStr]=!0);


ga('set', 'anonymizeIp', 1);

If your visitors should be able to set an Opt-Out-Cookie (No future tracking) you can set a link e.g. in your imprint as follows:

<a href="javascript:gaOptout();">Deactive Google Analytics</a>

The “respectDNT” option

If you enable this optional option, Google Analytics will not be loaded at all for visitors that have “Do Not Track” enabled. While using Google Analytics does not necessarily constitute Tracking, you might still want to do this to cater to more privacy oriented users.

The “exclude” option

If you need to exclude any path from the tracking system, you can add it (one or more) to this optional array as glob expressions.

The “optimizeId” option

If you need to use Google Optimize for A/B testing, you can add this optional Optimize container id to allow Google Optimize to load the correct test parameters for your site.

The “experimentId” option

If you need to setup SERVER_SIDE Google Optimize experiment, you can add the experiment ID. The experiment ID is shown on the right-hand panel on the experiment details page. Server-side Experiments

The “variationId” option

Besides the experiment ID you also need the variation ID for SERVER_SIDE experiments in Google Optimize. Set 0 for original version.
