• How to track Google AdWords campaigns with Matomo

  19 décembre 2017, par InnoCraft

  In 2016, Google AdWords was the most popular ad service on earth. As a result, it may be your first source for ad spending. Are you interested in knowing whether you are making a profit out of it ? Would you like to know how to track users coming from AdWords with Matomo (Piwik) efficiently ? This is what this article is about.

  

  What you need to know about Google AdWords

  By default, each ad you create in Google AdWords is not tracked. Even worse than that, every click on your ad is identified in Matomo (Piwik) as an organic result coming from Google with the following value : “Keyword not defined”.

  To make it simple, if you do not track your AdWords campaigns both your paid and organic traffic will be biased within your Matomo (Piwik) account. It will be impossible for you to measure your return on investment and it means that you are throwing your money down the drain.

  In order to avoid this, we will show you how to track Google AdWords traffic into Matomo (Piwik).

  How to track paid Google AdWords campaigns into Matomo

  If you want to analyze Google AdWords campaigns within Matomo (Piwik) properly, you need to add additional tracking parameters to the final URL of each of your ads.

  We recommend using the following tool to add the needed additional tracking parameters : https://matomo.org/docs/tracking-campaigns-url-builder/

  You will then be able to push additional data to Matomo (Piwik) such as :

  • pk_campaign : the name of your ad campaign
  • pk_kwd : the keyword associated to this campaign
  • pk_source : the source of your campaign
  • pk_medium : the type of source, in our case either cpc, cpm, cpa
  • pk_content : the content of your ad

  If your campaign URL looks like this : https://your-website.com/, your campaign URL will then look like this after adding the campaign parameters :

  https://your-website.com/?pk_campaign=Name-Of-Your-Campaign&pk_kwd=Your-Keyword&pk_source=google&pk_medium=cpc&pk_content=My-Ad-Headline

  As each ad URL can be fired by different keywords and can correspond to different campaigns or headlines, you will need to customize the campaign parameters for each URL.

  Customizing all of your URLs individually would take you a lot of time under circumstances. That’s why you should know, that each URL parameter can be filled automatically in AdWords with a feature called “Tracking template”.

  Simplifying the campaign URL parameters with tracking templates

  You can define tracking templates either at the account, campaign or ad group level. For example, by using a tracking template at the account level, all your campaigns will have the same landing page with the URL parameters you defined in the tracking template. By defining it at the campaign level, it means that all your ad groups within the campaign will have the same landing page and so on and so forth. Any tracking template defined in a campaign, will overwrite a tracking template defined at the account level.

  Tracking template at the account level

  To edit the template at the account level, you need to click on “Settings”, then click on the “Account” settings tab and define your tracking template pattern. For example :

  https://your-website.com/?url={lpurl}&pk_campaign=AdWords&pk_kwd=Your-Keyword&pk_source=google&pk_medium=cpc&pk_content=My-Ad-Headline

  

  This will apply to all your URLs within your account. So it is only useful if your website domain is the same across all your ads. The URL parameter is compulsory here.

  It can be limiting to have a static value for “pk_campaign” and “pk_kwd” so Google allows you to use dynamic insertion, such as follows :

  https://your-landing-page.com/?url={lpurl}&pk_campaign={campaignid}&pk_kwd={keyword}&pk_source=google&pk_medium=cpc&pk_content={creative}

  The “keyword” means that the data is automatically replaced with the keyword which fired the ad within your account.

  Visit the following page if you want to know more about the different dynamic tags that AdWords supports : https://support.google.com/adwords/answer/6305348#urlinsertion

  Tracking template at the campaign level

  If you wish to define a tracking template at the campaign level, you will find this option within the “Campaign” settings under the campaign URL options :

  

  Tracking template at the Ad Group level

  You can also set it at the Ad Group level within the “Ad Group” settings :

  

  As Google mentions : “If you set up URL options at the campaign level, ad group level, or ad level, those settings will override the account-level options“.

  Now that your URLs are properly configured, you will be able to analyze AdWords traffic performances within Matomo (Piwik) once a click is coming from those sources.

• Can't play at a good framerate with JavaAV

  31 mars 2017, par TW2

  I have a problem in framerate when I use JavaAV (which use JavaCPP + ffmpeg). When I set my framerate as mentionned at DemuxerExample.java, the frame change each 47000ms which is too long and false. It’s better when I set 1000 / demuxer.getFrameRate() * 1000 ( 47ms) but it’s also false. I can’t have a good framerate. Here is my player class :
