Then, mass customization techniques are used to produce and ship the doll. As consumers experience this level of customization more frequently, they begin to assume that since the technology is available, all sites should be able to offer this convenience. Now is a good time to review the interactive features of your site to see if it's time for a personalization makeover. These are the sites your audience sees, and the sites that set your visitors' expectation level when they come to your site. These are the people who have used your web site and are best equipped to give you an outsider's opinion.
Many sites link to vendor sites to add shopping carts and discussion forums.
That trend continues as sites link to vendors who supply syndicated content, personalized email newsletters, calendars, and a variety of other interactive features. Since the personalization supplied by outside vendors normally requires profile data, it's important to make sure you can obtain the data they collect on your behalf. Some of these services store data using one-way encryption, which means it cannot be decrypted and exported in a form you can use. So be sure to include your technical team when evaluating new technology provided by an outside vendor. It's always hard to project the ROI of investments like this, so look for ways to link to outside services that will enhance your site.
