When it comes to trusting brand sponsorships, Latin American countries lead the way with 81 percent of both Colombian and Venezuelan Internet consumers and 79 percent of Brazilians trusting this form of advertising.
In contrast, sponsorships hold the least sway amongst Swedish (33 percent), Latvian (36 percent) and Finnish online consumers (38 percent).
In comparison, 52 percent of British Internet consumers trust brand sponsorships, placing Britain 34th out of the 50 countries surveyed.
Brand websites, globally the most trusted form of advertiser-led advertising, hold the greatest sway in China (82 percent). Following China are Pakistan (81 percent) and Vietnam (80 percent).
However, brand websites tend to be trusted least amongst Swedish (40 percent) and Israeli (45 percent) Internet consumers.
Britain ranks 38th amongst the countries surveyed with 58 percent of British Internet consumers trusting brand websites.
"The regional differences provide a clear guide to advertisers as to how they should focus their ad strategy in different countries.
"It also shows that, despite the authority of word of mouth when it comes to consumer decision-making, advertisers still have a major say in the process.
"This is backed up by past Nielsen studies which showed that the majority of people posting comments online went to the advertiser website or emailed feedback to the company before they posted.
"The website, and monitoring feedback through it, is a golden opportunity for advertisers to shape the tone and content of consumer opinion before it reaches the digital masses," said Carson.
Although brand websites score highly among Internet consumers, the survey shows that other forms of digital advertising are trusted less than ads appearing in traditional media such as TV billboards, radio, magazines and newspapers - despite the latter being the only form of advertising to experience a drop in levels of trust since the 2007 survey.
Text ads on mobile phones (24 percent), online banner ads (33 percent), online video ads (37 percent) and ads in search engine results (41 percent) are the forms of advertising least likely to elicit a degree of trust.
Carson concludes, "Despite the huge increase in the size of the world's Internet population and the sheer amount of time being spent online, the industry has yet to attract advertising revenue consummate with the current levels of online media consumption.
The study shows there is still work to be done to shift advertising revenue from traditional forms of media to the Internet.
The ability to turn this around rests on overhauling the way display advertising is served online so that it becomes a more effective medium for brand advertisers and a more trusted form of advertising in the mind of the consumer."
