It's an easier way to source all of those testimonials that people have on their website and really cool because it shows that people "like me" value the product. If they do their job right, you could have a testimonial that is more valueable than anything you could have sourced yourself because you are surfacing that diamond in the rough. Especially if you a big brand with thousands, or millions, of people tweeting at you.
Cool prooduct, nice work guys.
In fact, the exact opposite concept of this could exist, scrape Twitter for consumers to show them who they shouldn't do business with, and it would still be social proof.
Again, in this context, a company will always seek out positive social proof.
What you said about social proof is absolutely true! It is the relevancy that helps people make a decision and through credibility it is even easier.
The tweets we suggest are high-signal and we believe it will help your product, newsletter or whatever you are selling.
So the company is able to "lie" to potential customers.
How companies manipulate Glassdoor is an interesting case study
I doubt there is more money in that direction though
E.g. on Amazon I ended up only ever reading 3 star reviews. Not for their positivity or negativity, but because they often point out some shortcomming of the product that might or might not effect me. Say some audio hardware not supporting some MIDI feature. I might not care about it at all, or it is a dealbreaker. I have made more pruchase decision based on those reviews than positive ones. For the latter what usually lacks is knowledge about the context, the use case they have.
If you filter for positive shoutouts only, the result becomes strongly biased by definition :).
Tweet compilations actually decrease trust for me if they are on a website. Twitter sucks overall and bringing obviously filtered tweets is a turnoff.
As a consumer in both business and general, I want third parties who give unbiased reviews, covering multiple vendors / products which solve my problem. This is why genuine influencer marketing is doing well. I actually spend a fair amount of time on youtube looking at reviews and finding trustworthy sources there. They need to point out flaws and put some products down do gain that trust
How does this filter even assure that these are real accounts and not bots or a Serbian click farm selling positive impressions?
Step 2, use tweets for marketing
Since they're Tweets it's also theoretically organic, which is even better.
