Global Online Advertising Industry: An Analysis from Aarkstore Enterprise looks at global online ad spend and notes the trends in different countries worldwide.

In Canada, for example, internet marketing accounts for roughly a third of all expenditure on advertising.

However, the US is said to be the most well developed market for internet marketing worldwide.

Reporting rapid growth in the internet marketing sector, Aarkstore Enterprise suggests that the emergence of social networks in recent years has helped to buoy the industry.

Meanwhile, the UK leads alongside the "pan-European sector" and the Netherlands in terms of online ad spend by geography.
