Customer service is the provision of service to customers before, during and after a purchase.
There are different levels of knowing your customers, often customer service relies on demographics or customer data collection. Yet, customer and customer dynamics as a group are affected through modalities of experience. Hence it is important to know your customers and to the culture that you want to create. This is where psychology enters into the realm of customer service.
Customers tend to be more forgiving of organizations who acknowledge and apologize for their mistakes rather than denying them. Taking responsibility for mistakes and correcting them is considered an important aspect of good customer service. When a customer experiences poor service and is ignored, the customer is less likely to return to that company again. Stonewalling is unforgivable, but unfortunately common.
Customer relationship management (CRM) is the practice of intelligently finding, marketing to, selling to, and servicing customers. CRM is a broadly used term that covers concepts used by companies, NGO’s and public institutions to manage their relationships with customers and stakeholders. Technologies that support this business purpose include the capture, storage and analysis of customer, vendor, partner, and internal process information. Functions that support this business purpose include Sales, Marketing and Customer Service, Training, Professional Development, Performance Management, Human Resource Development and Compensation.
The best way to get a new customer is through customer referal. With every new lead you must run after the new customer. If you do not then someone else will.

George O,
Here are some tips for marketing online:
1. Become an expert on the subject.
Most people are not doing this, so you’ll have an edge up. Start marketing yourself in forums, chatrooms, and blogs as an expert on whatever your website’s subject is. Find out why your product, service, or website is better than anyone else’s. (Then tell other people that!)
2. Give away tons of free samples of your product.
With online websites, it’s really easy to find 100000 websites that sell or do the same thing. Make people able to TRUST your website by giving away your product for free, and then by having people write back in and saying how well it’s worked for them. Otherwise, they won’t trust you, and they’ll just leave.
3. Come up with, and market, your USP.
(Unique Selling Point) You need to show people why you’re better than anyone else!Anyways, I hoped this helped. This stuff is just the TIP of the iceberg of marketing!
Good luck!
