What will be an ideal response?

? The nature of blogging and social media allows us to rate companies, service, prices, etc. If you receive poor service you can blog about it and that could have a negative impact on the company. If you get an excellent deal on a purchase you can also blog about it or post it on Facebook and that will have a positive impact on the company.
