SearchTools Analysis: Recommendations for Search Results

Recommending Pages for Special Searches

Search engines use statistical and lexical analysis to match query terms to indexed text, but often, human judgment is more effective. Many search queries are for names, items or even ID numbers. For the most frequent questions on a site, it makes sense to manually identify the best page or pages, and integrate these into the search results. You may want to do this for the top 25 or 100 questions, depending on the traffic on the site. Instead just of relying on the search engine's ability to match terms, you can add human understanding to make the results more useful for the common cases, making best use of both approaches.

Dell does a pretty good job of this: they make sure that a bunch of appropriate introductory pages show up when users type the query "linux" on their site. As shown the example below, if they had not done that, the search engine would have shown them only the Large Business Linux pages first, and people in other situations would have thought that there was no Linux solution for them.

Another way to approach this is to consider the most common searches on a site as candidates for a Knowledge Base, and the manual links in the search results as pointers into that database or FAQ.

The 2001 Forrester Search Report quotes a telecom company site administrator as saying "About half of our visitors come to the site looking for a specific product." When a site visitor searches by a code, such as an error message or product ID, the search engine should recognize the pattern and make sure that the appropriate types of pages, such as product specs, troubleshooting or FAQs, come first in the search results.

For example, at the Sharp USA site, searching for a laser printer using Atomz search and promote tools brings up a special offer:

  • Intranet Usability: The Trillion-Dollar Question Alertbox at, November 11 2002 by Jakob Nielsen
    Results of an international usability study by the NNGroup on intranets finds that many are wasting employee time by failing to provide usable intranets. They found that "search usability accounted for an estimated 43% of the difference in employee productivity between intranets with high and low usability." They recommend that intranets make sure that the main search engine indexes all pages, shows results in relevance order with manual recommendations at the top, encourage useful page titles and descriptions. The NNGroup finds that tasks requiring 27 hours annually on a usable intranet could take as long as 196 hours on a less-usable one.
  • Beyond the spider : the accidental thesaurus. Searcher Magazine, October, 2002, by Rich Wiggins new
    An excellent article providing examples of manual recommendations at the AT&T web site and AOL's Keywords. A case study of creating the Keywords feature at Michigan State University describes the process of designing and maintaining a manual recommendations database. Also analyzes the distribution of queries in the search logs, which conform to the Laws of Pareto, Bradford and Zipf, showing that concentrating on a very few common cases will provide the best return for effort. A similar function, implemented at Bristol-Meyers Squibb, has had great success.
  • Why search is not a technology problem: Case Study, BBCi Search (follow link to 3.4 MB PowerPoint file) ASIST IA Summit February 2002 by Matt Jones
    Describes how the British Broadcasting Corporation added a search engine to their web site, offering access to both all the information in the BBC site and web-wide information. The group created some "use models" to show examples of information needs and find ways to add context to search results. They chose to create a taxonomy based on the most frequent searches, and test the process over the course of several months, starting with paper prototypes. They found significant user sensitivity to wording and layout, and to functions that break with their expectations. Showing manual recommendations was successful once they integrated with the other results, and people loved the search zones tabs once they found them (after several visits). Recommends early testing and use models to learn how people really use search engines.

  • New HP Wetware Product leads to Smarter Search Louis Rosenfeld's Blog, September 13, 2001
    Describes the recommendations links at the Hewlett Packard site for such common topics as handhelds, and suggests that the hybrid of manual "best bets" for popular queries with standard search results is a hopeful trend.

Examples of Sites with Recommendations

Search Tools Supporting Manual Recommendations

  • AskJeeves - originally a question-answering customer service search engine
  • Atomz - recognizes special meta tags for top ranking, Atomz Promote provides powerful tools to control exactly what appears for specific search results.
