Below are a few quick ideas on how you can advertise on Google Adwords audiences who have previously interacted with your account
An important thing to note before getting started:
**Remarketing lists** targeting the Google Display Network must have a minimum of 100 active visitors or users within the last 30 days for your ads to show; **lists** targeting Google search must have a minimum of 1,000 active visitors or users. **List** targeting on Gmail ads must have a minimum of 100 active users or visitors.
Since you have such a small number of visitors it’s unlikely that you will be able to retarget these audiences with a high level of effectiveness on AdWords without outside data. To do this you should link your Adwords and Analytics accounts (see below). This will allow you to create Custom Audiences and download Engagement Packs. With these tools, you may have had enough traffic in the last 90 days to actually target and bid a PPC ad.
There are two ways that I would approach this, one is from a **dynamic remarketing** perspective serving up banner ads to past product/service visitors. The other is through targeting and bidding (**PPC ad with “Target and Bid”**) on users who have previously interacted with your site and based on the keywords that you mentioned in your comment. It should be noted that it’s going to be important to set up an event tag with custom conversion value in order to truly understand the impact of your advertising efforts.
