An online tutoring service would like to increase the relevance of its ads by integrating them into articles and videos aimed at explaining academic concepts. Which strategy should be used to increase the conversion rate?

Website personalization involves customizing the user experience based on individual preferences and behaviors. While this strategy can improve user engagement, it does not specifically address the integration of ads within content, which is essential for increasing conversion rates in this context.

Search engine marketing focuses on increasing visibility in search engine results through paid advertisements and optimization. Although it can drive traffic to the service's website, it does not involve the integration of ads into existing content like articles and videos, limiting its effectiveness for this specific goal.

Targeted email ads are designed to reach specific audiences based on their demographics or previous interactions. While this approach can be effective for conversions, it lacks the relevance and integration that native advertising provides, which is critical for enhancing user engagement with the academic content.
