Community Tagging An Important Factor For Search Ranking
Filed in archive SEO by Arun Radhakrishnan on May 17, 2008
An excerpt from SEO By the Sea
There were a few rules followed in the process of clustering together photos from landmarks identified by tags from community members who took the pictures and uploaded them to Flickr. The authors tell us that the following assumptions were at the core of those rules:
(1) A cluster would contain photos taken from many different users, indicating that there is a broad interest in the subject shown in the photos,
(2) There would be some amount of visual cohesiveness in the images - in other words, people were finding the same things about the scenes at the locations interesting, with the same objects being photographed or the same type of photos being taken, and;
(3) The group of photos would be distributed relatively uniformly in time - showing that there was an interest in the landmark itself, and not a specific event that happened at the landmark's location.
Observing time-lines in the creation of tags and using that information along with the data obtained from keywords used by users and the actual images that they click on is a process that will get more refined as activity on the web increases.
