Hello, can you please explain to me what will be the best answer to this paragraph? Are you agree or not?

Digital marketing tools were always expected to make things faster, but some of the biggest changes that they have brought to bear are faster and more accurate metrics, increased interactivity with potential clients, and typically lower overhead costs than pre-digital marketing tools. Before digital marketing, a company would make an ad and mostly hope for the best, whereas now, marketing experts can tailor specific ads to individual customers and have rapid feedback on the ads success.

While the digital marketing revolution has completely revolutionized B2C and B2B marketing, it has affected both in different ways. B2C marketing can cast a much wider, yet precise net and effectively reach its desired customer base through video, website, social media, and music advertising. B2B marketing uses similar tactics but through more professional-based channels such as LinkedIn, Facebook Pages, and websites. A successful digital marketing campaign can build a brand and its reputation (and protect/maintain it) as opposed to just communicating the name and product/service that the company provides.
