Grant Cardone has at least 8 sites that I was able to identify - however it appears that only 4 of them are central to his Google advertising strategy.
1) GrantCardone.com - main website offering Entrepreneur / Sales Training
2) CardoneUniversity.com - Sales Training "university"
3) GrantCardonePlaybook.com - Aimed at helping people to build wealth
4) CardoneOnDemand.com - Automotive Sales Training
It appears that there is a 40/60 split between the Google Search Network and the Google Display Network -with substantial retargeting taking place. All traffic is also being pixelled for Facebook, and followed cross-platform.
Their Google display ads are bright, colourful and branded to each particular product. The majority of them are branding Grant as the brand authority, except with cold traffic who may not have heard of Grant initially.
The ads drive subscriptions to Grant's podcasts and daily emails, making use of the prolific content that Grant and his team create.
Sales are driven of all products and events directly with the ads and there are also flash sales and specific sale days throughout the year to drive demand.
The landing pages have two purposes - either to acquire opt-ins or sell directly - to a single product or event, or to a group of products.
Their products are sold directly to those on their retargeting lists, not directly to cold traffic (as one would expect).
