>B) If you want credibility, share testimonials from your prominent customers, not reporters who spent 5 minutes reading your press release

I don't know about this. If I read a testimonial on a website, I immediately assume it's fake.

I agree with article, but we run A/B tests for our landing page year ago and those "As seen on" logos increased our conversion rates.

I'd add to this... stop putting your own press releases on your website. It's even worse than press mentions.
