The rankings evaluate individual brands, not overarching companies, making Google's position at the summit doubly impressive as it is just one of the Alphabet brands.
In third place was Amazon, while Facebook moved up from 17th last year to ninth. The highest ranked British brand is Vodafone, which came in at 50th, 20 places down from the previous year.
Brand Finance analyses factors such as brand loyalty, familiarity, corporate reputation and marketing investment in creating the Global 500, and it also evaluates which brands are the most powerful.
This year's most powerful brand is Lego, with last year's leader Walt Disney falling five places. Lego has been boosted by The Lego Batman Movie, while digital innovations such as its new Lego Life social network have helped to broaden it into more of a shared pursuit.
Disney's ranking was hurt by the fact many of its biggest films last year were the work of sub-brands, such as Star Wars: Rogue One, which was produced by Lucasfilm, and Finding Dory, which was produced by Pixar.
Google was the second most powerful brand, with Nike taking third place.
Global fast food outlets McDonald's, KFC and Domino's Pizza continue to drop down the rankings of the world's most valuable brands, with McDonald's falling from 12th to 16th as it continues to be hit by associations with unhealthy eating.
"Increasingly, there is a view that you can't just have homogenous brands everywhere," said Haigh. "If you take someone like McDonald's, they do actually vary their menu quite significantly from country to country. It's fair to say that monolithic brands are fragmenting."
There is also a growing dissatisfaction across the globe with American brands, said Haigh, who added that the election of Donald Trump could impact a company's international standing.
"There was a period when American brands were considered to be very aspirational. Gradually goodwill towards American brands has been eroded," he said.
"One of the interesting dimensions at the moment is the extent to which Trumpism is actually going to accelerate this negative view about American brands."
