The social bookmarking phenomenon emerged several years ago as the trendy habit of people using free social bookmarking sites to categorize and manage their favorite webpages.
Traditionally, we resorted to the search engine’s internal classification system to handle your website’s themes. Search engines use the keywords on each webpage together with the keyword density to classify webpages by topic types. However, since search engines do not really understand webpages and keywords, they rely on statistical methods to classify your webpage according to their existing database of webpages with similar keywords.
Detecting when words are “similar” is easy for human beings. However, this is not an easy job for search engines, which are powered by computers. Computers do not understand synonyms that are different in spelling but similar in meaning. As I discussed in a previous post, several years ago Google acquired a company called Applied Semantics that attempts to handle this problem with its own invention, semantic technology.
Now the practice of “tagging” comes along to solve this problem. The best entity to determine a particular webpage’s classification is the webpage’s author, who is human being, fully understanding what the webpage s/he has written is about. Thus s/he “tags” it, using different words or sets of words to summarize the content of his/her website pages.
For example, since I am the author of this webpage, I can tag this it with keywords such as “social bookmarking”, “tag”, “tagging”, “Applied Semantics” or even some other related topics (such as social marketing sites “Technorati”, “de.licio.us”) that I think are the most important keywords related to this page. On the other hand, as viewed by a search engine, this webpage might be classified as “webpage” as this word appears most frequently in the article. Do you see the differences of machine versus human being?
At the same time, websites like Technorati and de.licio.us emerge as the mainstreams of so-called social bookmarking services as they allow users to register an account and bookmark their favorite websites with appropriate tags they themselves assigned to the webpages. They can even share their database with others (hence the term “social”). These bookmarking websites steadily emerge as a good source of “commentaries” and “classifications” of webpages in cyberspace. Some people further comment that the goal of tagging is not to classify, but to memorize.
It’s very logical that search engines will also consider the information from these bookmarking websites as a source of authoritative sites and webpages for particular popular keywords. This leads to the practice by some people of manipulating the social bookmarking websites (e.g., creating multiple user accounts to bookmark their own webpages with the carefully chosen tags as keywords) to artificially generate their own “popular” webpages within social bookmarking websites. Such people hope this will increase the search engines’ positioning of their webpages in search results.
An interesting book on this topic can be found here. This book teaches you how to use this tactic when blogging using popular website software like Wordpress, and actually reveals the drawback of referencing a webpage by tagging from the search engines’ perspective. This is because they are able to be manipulated by human beings, and so can create bias for a webpage.
The use of different variations of a keyword, such as “programme”, “program”, “programmes”, “programs” for the same concept can create a lot of confusion as well, creating additional problems with tagging.
One way to take advantage of this growing trend is to add a user-friendly component in your webpage to allow users to easily add your webpage to their favorite social bookmarking websites. If you take a look at the end of each post in my blog, you will see some lines of popular bookmarking websites like Del.icio.us, Spurl, Furl, Simpy, Blink, Digg, and those specializing in blogs like Technorati. Those lines allow my visitors to easily bookmark my webpage in their social bookmarking accounts. Someone coined the term “Social Media Optimization” (SMO), parallel to what we commonly referred to “Search Engine Optimization” (SEO). But note that SMO also extends to Web 2.0 sites’ optimization such as Facebook.com, Myspace.com, etc. We’ll talk about this in a later post.
