a more in-depth analysis of search engines, I would have to suggest a more tangible method of evaluating this criteria. However, I can’t see relevance of search results being measured according to ‘rules’; I think personal opinion is an important part of determining relevancy (what may be relevant to one person may be irrelevant to another). Therefore, I don’t think a definitive statement of a search engine’s accuracy and relevance for all people is possible. Due to the short time-span for this assignment and a lack of inside knowledge of the operation of search engines, the Speed criteria could be measured only by my own guess. This meant that no specific numbers about search speed could be returned and the results I came to are very much debateable. In retrospect, I

think the Speed criteria should have been evaluated according to the following points: CPU time taken to perform search (based on 100 searches). Of course, finding these details would probably require access to the search engine server. Average ping time (ping search server from about 10 worldwide locations). Again, this point would have been very difficult to do, especially in the limited timeframe. I think a measurement of speed according to the above points would be more accurate and useful, and would provide more specific results. I think the Search Options and Additional Services Criteria were very useful and establishing specific points that the search engines could be easily evaluated against (either true or false) made establishing a score for each search engine easier.

The only flaw with the criteria as set out in Part 2 was probably a lack of points, and the scope of these points may have been too narrow. For a more in-depth study, I think more criteria points would have to be established. I think the Layout and Design Criteria were too broad. I think for a more in-depth study, more (and more specific) criteria would have to be established. I would also suggest a true/false style points system (rather than three points per option system) for fairness and less personal opinion. Furthermore, I think the criteria addressed layout and design too generally, and not specifically for the advanced web user. In retrospect, I stand by my selection of search engines. I think they represented the search engines used by advanced web users, although I think

a more in-depth study would have to evaluate more search engines (I think Excite and Infoseek should also have been evaluated) because many advanced web users would also use the mainstream search engines such as Yahoo, Excite, AltaVista, Infoseek, Metacrawler etc. Overall, I think the evaluation performed was adequate as a more simplistic evaluation. While some problems with the criteria became apparent after use, I think the criteria were generally fair and useful for an advanced web surfer. 6.
