"Consider how a mastery of search engine anatomy would help with the role of the teacher librarian in developing information literacy with colleagues and students."
Wow, I learned a great deal by fishing around in the help areas of Google, Yahoo and DMOZ. Even the vocabulary stunned me. Today's readings also made me wish I had invested in Google many years ago, as Google was one of the first search engines to use web crawlers. How Search Engines Work gives a clear overview for non-tech-savy folk.
DMOZ, which I had never heard of before, is a non-profit, volunteer organization which lists websites. Web page creators can submit their page and a volunteer approves the page and lists it. While this seems rather 1990's (!) according to Web Workshop a listing with DMOZ can help improve ranking and relevancy as Google's crawlers use DMOZ listings to create their own listings. Yahoo has a similar process, but also suggests to web page creators that they focus on key user search terms in titles of pages, to increase the chances of a 1-10 ranking.
What is the importance of relevancy and ranking... money. If people are creating webpages, they want to get hits to their site. Hits, in many cases, are monetized nowadays, so income can be generated through advertising; additionally, income can be generated through sales and services. According to many sources read today (see links) readers tend to stay with in hits 1-10, so the closer your pages comes to the top, the higher the chance someone will read it.
Meta data is an interesting topic, summarized simply as the tags one includes in the html code on your web page. According to Monash, though, "meta tags are less useful than they were a few years ago, largely because of the high rate of spamdexing". Never the less, a librarians understanding of metatagging is important as recognizing that key word searching will provide a greater level of relevancy that general searches. Demonstrating to students and staff the back pages of websites and showing the html code and metatags would help them to see how thinking out search terms prior to using a search engine, would save time and energy and result in more relevant websites appearing in the index.
I have noticed recently, that students tend to search in the http:// section of a webpage, and aren't using Google as much. They expect that their topic will appear as a website. Interestingly, very often they do hit with quick success.
Monash has a great set of key words to help create a Boolean search, so this page is worth keeping to show students how to use AND OR NOT in their searches to limit pages. For example, the site uses
"nirvana AND Buddhism, NOT Cobain. " as a way to make sure that a student's search does not come up with a set of sites irrelevant to a project on Buddhism.
