  swresample/resample : optimize exact_rational=on:linear_interp=on case
  separate dsp.resample to dsp.resample_common and dsp.resample_linear
  
  and choose to call faster resample_common even when linear_interp=on
  
  when c->frac and c->dst_incr_mod are both zero
  speed up resampling when exact_rational and linear_interp are both
  
  enabled because exact_rational force c->frac and c->dst_incr_mod to
  
  be zero when soft compensation does not happen
  benchmark on exact_rational=on:linear_interp=on

• How to track Google AdWords campaigns with Piwik

  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 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 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 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 Piwik.

  How to track paid Google AdWords campaigns into Piwik

  If you want to analyze Google AdWords campaigns within 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://piwik.org/docs/tracking-campaigns-url-builder/

  You will then be able to push additional data to 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 Piwik once a click is coming from those sources.
