>>> Google caccia via i nostri lettori.
Se devo essere sincero Jacob Nielsen non ha mai avuto un grande ascendente sulla mia persona. Ma mi sono facilmente e felicemente ricreduto dopo aver letto questa sua analisi sulle influenze che ha avuto Google sia sulla navigazione degli utenti che sulla progettazione dei siti da parte dei Webmaster.
In pratica salutiamo la fidelizzazione dell'utente. O cerchiamo di imbarcarlo. Tutto è lecito. Ma non tutto è efficace.
Moving between sites has always been easy. But, from an information foraging perspective, it used to be best if users stayed put because the vast majority of websites were horrible and the probability that the next site would be any good was extremely low. I thus advised early website designers to follow two design strategies:
- First, convince users that the site is worthy of their attention. As I described above, this means having good information and making it easy to find.
- Second, once they arrive, make it easy for users to find even more good stuff so that they stay rather than go elsewhere. An entire movement was devoted to the idea of sticky sites and extended visits.
In the last few years, Google has reversed this equation by emphasizing quality in its sorting of search results. It is now extremely easy for users to find other good sites.
Information foraging predicts that the easier it is to find good patches, the quicker users will leave a patch. Thus, the better search engines get at highlighting quality sites, the less time users will spend on any one site.
The growth of always-on broadband connections also encourages this trend toward shorter visits. With dial-up, connecting to the Internet is somewhat difficult, and users mainly do it in big time chunks. In contrast, always-on connections encourage information snacking, where users go online briefly, looking for quick answers. The upside is that users will visit more frequently, since they have more sessions, will find you more often, and will leave other sites faster.
The patch-leaving model thus predicts that visits will become ever shorter. Google and always-on connections have changed the most fruitful design strategy to one with three components:
- Support short visits; be a snack
- Encourage users to return; use mechanisms such as newsletters as a reminder
- Emphasize search engine visibility and other ways of increasing frequent visits by addressing users' immediate needs
Better intra-site navigation and better site maps may tip the balance slightly back in favor of longer stays, but it's safest to assume that users' visits to any individual website will become ever shorter
