Overview

Developing a site that uses Google Adsense has to be treated carefully. Developers often want to avoid their own clicks to not being penalized by Google and minimize the speed of loading pages when debugging the site locally.

It basically presents the following problems:

  • accidental clicks. Avoid repeatedly accidentally clicking on served ads while developing the site which can lead to an account ban.

Although publishers are not permitted to click on their own ads for any reason, we do understand that accidental clicks may occur. We therefore don't require that you contact us every time you click on your ads. Rest assured that your account is being properly credited for all clicks and impressions we consider to be valid.

  • speed. Testing the site locally without waiting for each ad request to resolve, avoiding any javascript external request.

There are two main options to avoid them:

  • telling Google that the ad request is only for testing purposes
  • avoid the javascript request at all

Alternative 1: Google code parameter to make tests

There is a special parameter that can be enabled in Google Ad code to avoid accidental clicks and set them up as tests.

The downside of this approach is that it requires more checks to modify an ad code and if not enabled in production, ads clicks won’t generate any revenue.

To use this code you must have an AdSense account with active permission to use AdSense Custom Search Ads.

The parameter is 'adtest' : 'on' and it is defined like:

The adtest parameter is used to indicate that a request for ads is a test. When the adtest parameter has a value of on, Google treats the request as a test and does not count the ad impressions or track the clickthrough results.

An easier and safer alternative is to avoid the ad request at all.

Alternative 2: Avoid showing adsense ads locally

Jekyll templates can access the value of an environment variable passed at build time to avoid any external javascript request. Based on this variable the ads can be chosen to be shown or hidden depending on its value.

When building the site with jekyll build the variable JEKYLL_ENV defaults to development, setting it up as production makes it possible to hide the ads in liquid templates

To build a production ready jekyll site it can be specified like this:


$ JEKYLL_ENV=production jekyll build


When using bundler it should be used like:


$ JEKYLL_ENV=production bundle exec jekyll build

Environment in Jekyll liquid template

The environment can be accessed through the variable jekyll.environment.

The Adsense ad code provided by Google can be surrounded with the environment detection so they only gets loaded in production like this:

{% if jekyll.environment == "production" %}
  <script async src="//pagead2.googlesyndication.com/pagead/js/adsbygoogle.js"></script>
  <!-- simpleit_after_content -->
  <ins class="adsbygoogle"
       style="display:block"
       data-ad-client="ca-pub-****************"
       data-ad-slot="***********"
       data-ad-format="auto"></ins>
  <script>
    (adsbygoogle = window.adsbygoogle || []).push({});
  </script>
{% endif %}

A good practice is also to include something locally when not showing them, to quickly identify ads placement, it can be:

  • text with some color different from the rest of the site design
  • a placeholder
  • an image like the ad from example ads
