Think of it this way. . . would you use copy that would work equally well for your competitors? Copy that if they just changed the name of the company or product would work for them as well as you?
If you use copy that makes you look just like everybody else, you're giving the reader no compelling reason to buy from you (unless you're the cheapest). You're communicating no clear benefit over your competitors. It's the same with your photos. Stock photos don't cut it.
Use professional photos of your staff, facilities, products, processes and happy customers to build trust, convey quality and create desire. Choose images that strategically communicate the benefits that you or your products provide. Don't choose images just to make your website or brochure pretty. Use images to influence how buyers see you.
Perception is everything.
