The story accurately reports on the increased advertising spending by Shein and Temu in Europe, specifically in France and the UK, as well as the reduction in the US. These claims are supported by data from Sensor Tower, a credible source for app analytics. The article also correctly attributes the strategic shift to the end of the de minimis exemption by President Trump, which previously allowed the companies to import goods duty-free into the US. However, the article could improve its accuracy by providing more detailed data on the specific figures for advertising spending increases in other European countries and the long-term impact of the tariff changes on these companies' operations.

The article presents a balanced view of the challenges faced by Shein and Temu due to the new US tariffs and their strategic responses. It includes perspectives on both the companies' advertising strategies and the potential limitations of their market expansion in Europe. However, the story could benefit from additional viewpoints, such as insights from industry analysts or competitors, to provide a more comprehensive picture of the market dynamics and competitive landscape.

The article is generally well-written, with a clear structure and logical flow of information. It effectively explains the impact of the US tariffs on Shein and Temu's business strategies and provides relevant data to support its claims. However, some readers might benefit from a more detailed explanation of the de minimis exemption and its implications for international trade.

The article relies on data from Sensor Tower, a reputable source for market intelligence, which enhances its credibility. The inclusion of expert commentary from Kimber Maderazzo, a marketing professor, further supports the analysis. However, the article would be strengthened by citing additional sources or reports to corroborate the claims about the impact of tariffs and the companies' strategic shifts.

While the article provides some context for the strategic changes of Shein and Temu, it lacks detailed explanations of the data collection methods used by Sensor Tower or the specific criteria for measuring advertising spending. Additionally, the article does not disclose any potential conflicts of interest or affiliations that might affect the reporting. Greater transparency in these areas would improve the article's credibility.
