Remarketing is a clever way to connect with visitors to your website who may not have made an immediate purchase or enquiry. It allows you to position targeted ads in front of a defined audience that had previously visited your website - as they browse elsewhere around the internet.
Your remarketing ads can show on any website that accepts advertising from the Google Display Network and in NZ this includes many of the most popular local websites like NZherald, Trademe, Metservice, Stuff and many more. There is a high degree of targeting flexibility and you can even filter your targeting to show only on specific sites and or exclude specific sites.
At Adhesion, a lot of our clients find remarketing to be a very cost-effective form of online advertising for reminding visitors to purchase your offering(s) and increasing brand awareness. For any business with a website, if you're considering advertising online, our experts highly recommend investing in some remarketing.
Google Remarketing is an ideal advertising tactic especially where the sales process is long and considered and competitive. Executed in the right way it can be a powerful tool to improve sales conversions and to raise your brand profile.
Most remarketing ads are delivered in text and or image display formats and are managed from within Google Ads (AdWords) platform. A growing number of ads are becoming animated including video formats. Image animation in display ads is usually achieved by using GIFs or HTML5.
Display ad sizing options are determined by the spaces allocated on websites that accept the advertising. There is a large number of standard sizes and at Adhesion we normally recommend building display ads to the most common 4 or 5 sizes.
It's quite simple really. Remarketing works by placing cookies on your website visitors' device(s) when they meet your criteria. Their cookie ID is added to your remarketing audience list. You can have multiple lists with a range of different criteria.
For example you may wish to target visitors that viewed a particular page or section on your website but didn't make a purchase or complete and enquiry form.
Each cookie has a unique ID which is automatically added to your remarketing list. You can have multiple lists with a range of different membership periods, goals and criteria.
There are a number of advertising controls including the period of time that a cookie ID stays on your remarketing list, impression caps on how many ads per day are shown to an individual and the ability to block ads on certain websites. You can also set criteria to control the targeting of your ads, for example: by age, gender, location and interests based on your browsing behaviour.
The Google remarketing feature has recently been through a revision and Google has added more features and controls for advertisers. The remarketing feature now allows more flexibility through using upgraded Google Analytics code. This allows for lists to be created and managed without the need to place specific code on the website.
However, be aware of some recent changes that can affect remarketing:
Don’t worry, Google is responding by updating their Google Ads (AdWords) cookies so that everything (i.e. ‘conversion attribution’) will work as normal. However, expect to see some drops in activity from Safari users. How much of a drop? Well, to give you some idea, nearly half of mobile users use Safari due to iPhone being so popular, and slightly over half of all traffic is now mobile.
There is a minimum threshold of 100 cookie ID's on each remarketing list before a campaign can become active.
To be successful it's important to
If your aim is raise brand awareness then you can create ads that achieve exactly that by displaying your brand to visitors over a period of days, weeks or months. And as remarketing is part of Google Ads (AdWords) you will be able to track outcomes through normal conversion tracking.
We’ve learned that with display ad formats, may people will not click directly on the ad but will be prompted and motivated to revisit the website through normally pathways (direct and organic). This makes normal ad metrics less relevant with display ads and we normally recommend using view-through conversion measurement which requires Google Ads conversion tracking code.

Facebook remarketing works very similarly to Google remarketing, except that audience lists can be made from people’s Facebook User IDs and phone numbers (as well as their emails). You can then take these lists and generate smart lists of Facebook users called ‘Lookalike Audiences’.
Put simply, Facebook generates an average user based on the people in your list, then creates another list out of Facebook users who are 99% similar to your average user. This is an impressively powerful feature for reaching potential customers.
