Ad libraries from advertising platforms: research what your competition is doing.
Ad libraries from major advertising platforms
An ad library is a repository or large public database containing all the relevant information about active ads. You can find data such as campaign text, images, and videos, targeting details, start and end dates, advertiser information, and ad spend. However, the amount and type of information will vary depending on the ad library you're using.

AliExpress Ads - EU Advertising Transparency Repository
In this first section, we'll discuss the AliExpress ad library, which collects advertising generated throughout the EU . Any user (as it's a public repository) can search for ads without needing an AliExpress account.
To perform a search, you must first select the European Union country in which you want to search for ads, then enter keywords or the advertiser's name into the search engine.
In this case, AliExpress stores both active and inactive campaigns in its ad library. It even displays ads that have been removed for violating company policy, although in these cases the information provided is more limited.
Additionally, for those users who wish to perform a more personalized search, AliExpress has made an API available .

In the case of Amazon, you will only be able to access ads that have been published during the last year in the Amazon store, as well as affiliate marketing content .
As for the countries you can access, the number is more limited than with AliExpress, being restricted to Europe, but there is also an Ad Library API.
When searching, you can enter the name of the brand, advertiser, creator, author, or product. However, the results do not include images of the advertised products.

Google Ads - Advertising Transparency Center
The Google Ads ad library is called the "Advertising Transparency Center." The existence of this section on the various advertising platforms is primarily due to the obligation to comply with certain legal transparency regulations . In Europe, for example, this obligation is included in the Digital Services Act, which seeks to protect users and guarantee greater advertising clarity.
But returning to Google's ad library, in this case, only active ads with a maximum age of just under six years are displayed. The country-by-country search options in this case are much broader than the previous platforms we mentioned, as Google allows you to view ads from virtually any country in the world , not just those in the EU. You can even search by platform and choose different Google environments, such as YouTube, Google Maps, or Google Shopping , among other options.
In the search engine, you can enter the advertiser's name or website to perform the search and choose whether you want to display all topics or only ads related to political issues.
