Thus, a customer database can include from contact data (mail, telephone etc.) to specifications and details about the transactions performed. The type of information that you are requesting from your customers always depends on the utility that you have for your business and your marketing strategies.

For example, a real estate business owner knows that people usually buy a house only once in their life, so you will not need to store as much information regarding your buyer’s preferences, unlike a hairdresser whose clients usually make one or more visits per month.

So creating a database is the best way to keep your customers’ information tidy and up to date. It also allows you to contact your customers and prospects, build loyalty, provide a better service and promote your sales.

To Recap, What Is A Database Worth From The Marketing Viewpoint?


Having information from your customers, from contact information to their particular preferences allows you:

  • Increase your sales through techniques such as email marketing, telemarketing or telephone marketing, etc.
  • Retrieve old or undecided clients by taking advantage of the remarketing strategies.
  • Offer personalized promotions tailored to each customer based on their profile in your database (preferences in payment modes, purchases made previously, etc.)
  • Keep your customers and prospects informed about your novelties, special offers, etc.
  • Provide quality care, that is possible thanks to the registration of the specific characteristics of each client in your database.

What Kind Of Information Can You Collect In Your Customer Database?

If we think about how to  Create a Customer Database, there are three major sources of information that largely determine the type of data you can collect. They are the following:

  • Your Business
  • Your Website
  • Your Social Networks

Your Business

It allows you to obtain the most “hard” or specific information related to real customers: you can register the name of your buyers, their address, telephone or email, their credit card, the product they bought, what date they did it, etc.

Your Website

In addition to being the “virtual cover” of your business, or your cover letter, your website is a very complete and valuable source of information on getting specific information about your audience, that is to say, those people who are interested in your proposals, which cover your online offers, etc.


Using a free tool like Google Analytics you can know who visits your site, what sections or products they have explored, where they came from, how long they’ve been on your website, and more.

Your Social Networks

Besides to being the virtual space par excellence for the capture of your audience and the positioning and promotion of your brand, Social Networks are an excellent source of information for your database.

Beside to analyzing the profile of your followers, after posting a post on Facebook, Twitter, etc. You can study the impact of each type of publication on people interested in your proposals, reviewing the amount of times shared, receiving Likes and getting Comments.

That way you can register what your audience likes best and improve your content marketing strategy. You can also analyze users that enter into a particular demographic profile, based on criteria such as age, gender, and location, as a complement to your market studies.

If you have a mobile phone company you can relieve the customers who buy all the new features you offer and give them special offers.
