Portal is a new term, generally synonymous with gateway, for a World Wide Web site that is or proposes to be a major starting site for users when they get connected to the Web or that users tend to visit as an anchor site.

Stickiness Portals, Search Engines, Web Servers, Bots, Shopping Carts…
"Stickiness" refers to a Web site's ability to attract engaged, repeat visitors who spend more and more of their time on a given site instead of briefly alighting and then flitting off to some other corner of cyberspace.
The two most important measurements of what a Web site has to offer advertisers are
ad views and the average time each visitor spends on the site.
If you can make your visitor spend more time at your site, they will view more ads and they can be considered more loyal to the site and presumably somewhat more likely to click on the ads and patronize advertisers.
