How long time to get my Remarketing tag inlcuded into Google Adwords interface ?

How long we have to wait for validation of my remarketing tag in Adwords ?

Taking into account the Remarketing tag your Google Adwords account can vay according to the frequency of the indexation of the URLs of your site.

Google doesn’t give any precise information about how long it takes for validation but based on the comments of several clients, we have conclued that it almost always takes several days ? We tested this in our online shop and we had to wait approximately five days.

We emphasized that time needed for this variable and can be shorter.
We think that it depends on the number of pages that Google has to index again for your shop.
