Which of the following is an alternative to cookies being developed for advertising and e-commerce?

• A. Contextual advertising only
• B. Interest-based advertising (IBA) and methods for website remarketing without third-party cookies
• C. Traditional banner ads
• D. Social media widgets

Answer: (B)

The idea being tested is how advertising and e-commerce can work without relying on third-party cookies. The best answer combines two practical responses: interest‑based advertising and methods for website remarketing that don’t use third‑party cookies. Interest‑based advertising targets users by inferred interests across sites, while non-cookie remarketing uses alternative signals or first‑party data to re-engage visitors without third‑party cookies. Together, they offer a broader, cookie‑less approach to both reach and re‑engage audiences.

Context helps: contextual advertising targets by the content of the page rather than by user tracking, which is useful but narrower and doesn’t cover personalized remarketing. Traditional banner ads describe a format, not a strategy. Social media widgets are tools for engagement, not a direct replacement for cookie‑based targeting and remarketing.
