The New York Times has a rare "can't-miss" article about the purchasing power and Internet adoption of the 50+ yr. olds in the US. Excerpted:

Ms. Dougherty said a recent Nielsen survey found that 27.4 million people age 55 and older bought something online in the last six months, compared with about 26 million a year ago. By contrast, the number of adults who bought something online in the last year actually dropped, to 107.4 million from 112 million.

Ms. Dougherty said that since last June, senior citizens have bought clothing, shoes, flowers and gifts at a faster rate than the population in general.

To me, those statistics are massively compelling and signal a significant change in how web designers, developers and yes, SEO/Ms, too must conduct online campaigns.

Mr. Byck cited figures from the United States Census Bureau that showed while 40 percent of the United States population was 50 or older, this group held 75 percent of the nation's financial assets and did 55 percent of all consumer spending. "Without sounding overly harsh, in many ways marketers have taken the 50-plus market for granted," Mr. Byck said. "The reality is that you can't do that anymore."

Ms. Dougherty of Nielsen said one reason businesses had overlooked older consumers was that they were fixated on the 18-to-34-year-old market. Both online and off, the younger group has been heavily pursued by companies who think people's buying preferences are sealed during this span.

"To assume someone at 35 has made all their decisions about brands for the rest of their lives is utterly ridiculous," Ms. Dougherty said. "A lot of companies have an antiquated way of looking at older people, which makes little sense when you look at how much more disposable income they have now."

I rarely make big decisions based on media, but I think that some serious research and possibily a bit more older-demographic-focused usability testing is in order for several of our clients. The tough dichotomy is that these older demographics don't run blogs, don't post to social tagging sites, don't control links and media on the web and rarely are "influencers" of online trends. Thus, there's some issues of duality in terms of how to create a succesful brand online - we won't see MySpace or Flickr or Technorati shifting their focus to these demographics, but if you run a classic e-commerce site, especially one where older consumers could be a significant portion of your market, you cannot afford to ignore designing and building with their demographic in mind.

Any thoughts on how to keep a "Web 2.0" profile (to help attract links and attention from the "Linkerati") while successfully appealing to older consumers?
