If they asked me, I would tell them that there is no such thing as a relevant ad. Even if I'm shopping for a specific product, if an ad gets through my defenses I stop shopping. If I see an ad for your brand, I will avoid your brand.
And it's not just obvious ads. You can't trust online customer reviews, because there's an industry devoted to spamming them, both positively and negatively.
And you can't trust third-party reviews, because they're often disguised press releases. Or biased by payment. For example, I've been told that many sites that review VPN services basically auction their rating slots.
Some platforms have awakened to this, so they have rules or guides what to do when customer tries to blackmail free stuff with negative reviews. However, not all.
