extensions d'Google Ads

You can set within the interface as many ad extensions as you want to add for your campaigns of - ! Indeed, Google offers you these features limitless d’usage.

Cependant, bien que le paramétrage de ces extensions d’annonces soit un jeu d’enfant, il faut garder en tête que pour que les extensions d’annonces s’affichent, votre annonce doit remplir le seuil de qualité prévu par Google.

Dans cet article, nous faisons le point sur les différents types d’extensions d’annonces et comment les paramétrer dans vos campagnes SEA. 

What is the difference between manual and automatic extension? 

Google evolves its platform and regularly proposes new ad extensions. In order to be able to fully use the potential of these functionalities, it is first of all necessary to understand the difference between manual extensions and automatic extensions.

Google Ads directly creates the automatic extensions and displays them under the ads. Indeed, Google bases itself on its calculations by adding extensions necessary to improve the performance of the ads. For manual extensions, you will need to configure them within the interface by filling in additional information.

How much does it cost to set up the extensions?

Good news, you don't have to pay extra for setting up your ads! You pay the same cost for a click on the title of the ad. However, clicks are not charged for the manual extension "Merchant reviews".

For example, if one of your prospects or customers downloads your application from the application extension in your ad, then the click will be charged.

Dans tous les cas, vous ne payez que deux clics maximum par impression (que ce soit sur l’annonce ou sur ses extensions).

What are the manual extensions? 

  • Call extensions
  • Hook extensions
  • The location
  • Site extracts

Automatic extensions

How are the extensions displayed if you set them all up? 

It's Google Ads who chooses whether or not to display the extensions of your ads if the quality threshold of the ad is met. It is therefore Google Ads which will automatically choose the most effective combination in relation to the click rate per keyword. Google can choose up to 3 extensions different on the same ad, however it does not guarantee any type of broadcast. 

In short, if your ad extension is not triggered, this is due to the ranking of the ad, which is too low. If you notice that your ads are not displayed, we advise you to increase your bid and improve the quality of your ad. 


The ad extensions allow you to gain visibility and improve your click-through rate. The latter has an impact on the Quality Score taken into account by Google to classify the relevance of your ad. Eventually, c’est Google qui décidera d’afficher les extensions d’annonces ou non. Nous vous conseillons donc de tester plusieurs extensions et d’y ajouter des informations supplémentaires pour que les internautes remarquent du premier coup d’œil vos annonces. En ce sens, un bon paramétrage des extensions d’annonces permet d’augmenter les performances de vos campagnes et de maximiser votre ROI. Un atout indispensable pour vos campagnes SEA à ne surtout pas négliger, en somme.
