Abstract

Advice given in printed and web-based sources on HTML META tags with NAME='DESCRIPTION' is surveyed.To determin patterns of relationships among descriptions on the same site,links were followed automatically from 460 pages registered withYahoo! and previously found to contain descriptions.Sites where the registered page pointed to many other pages were significantly less likely to reuse the same description on those other pages; where different descriptions were used words from the registered page's description tended to appear toward the beginnings of other descriptions.
