I think the key with this approach is to be genuinely helpful and to avoid actually trying to sell a product. That's incredibly counterintuitive, but the product probably isn't the endgame for your consumer. What are they using it for? Be an expert resource on THAT.
The Home Depot blog is a really excellent example of this principle in action. Instead of selling their products, they're showing very creative and aspirational ways that people can use them. They did an entire DIY series on concrete. Concrete!
So they do all of these posts about concrete, but they're never pitching you a hard sell on it. The path to purchase is there if you want it, but really they're just focused on being experts on all of the wonderful, aspirational things you can do with concrete. It's very shareable and pinnable and I want every one of those projects in my home. They've planted the idea of buying concrete without selling it to me. It's very obvious they are an authority on concrete, and it doesn't matter that they're a seller. In fact, I'm more likely to buy it from them now because their expertise on it is clear.
So I started with that instead of outreach because when the content is that good, you can push it out on social and get a good response. You can share what you're doing with influencers and they won't mind because it's obvious you know what you're talking about. Next thing you know, they're coming to you for comment as an expert. The quality has to be there or you're right, you just look like you're pushing product and that does get tend to get ignored.
