Where business and technology create a winning customer experience.

I have seen the surveys. I have sat through the usability testing. And it comes up every time. Searchers on your company’s Web sites say that there are “too many results.” They did their search and they saw “1,000 found” or “Results 1-10 of 46,000″ and they feel overwhelmed. Why does this happen? And what are they really trying to tell you when they say there are too many results?


I remember the first time that the usability folks told me that customers wanted fewer results from the site search engine. The customers told us that is what they wanted, so we should do that, right?
“That’s ridiculous,” I chortled. “Why is Google so successful when it brings back millions of results for the same query?” And then I went to the usability tests. And I heard it again and again until I had to ask myself why is Google successful when this is what searchers are saying about your Web site search?
Why indeed? I think Google’s success is based on having the right answer at the top. (Duh!) At least most of the time, they do. And your site search often does not. Jared Spool found that site search actually answers the searchers’ question just 34% of the time. So it’s fair to say that there is a problem here, even if it isn’t the one that users are identifying.
Eye tracking studies show that the first place people look when a search results screen is displayed is the top left of the page, working their way down to the #1 result and scanning down the list from there. No studies show that people’s eyes are attracted to the number of results. So, you can safely conclude that people have already looked at the search results before they look at the number of results at the top right of the screen.
The only reason that they are looking at the number of results is that the results listed did not seem interesting enough to draw their click. So when users complain that there are too many results, what that probably means is that the top results were no good.
Sometimes, the answer to the searcher’s question is on your site, but was not anywhere listed in the results. In that case, the problem is that the search engine did not find the right pages, possibly because the content on the page was not well-written to match the searcher’s words, or because the pages were not even placed in the search engine’s index.
At other times, the answer to the searcher’s question is not on your site at all. You might be surprised how frequently the answer to the searcher’s question is not on any page. When that happens, you need to add the answers to your site.
Most frequently, the answer is on your site, and it is returned by the search engine, but it is ranked so far down in the list that the searcher does not see it. In that case, the search engine’s ranking algorithm may need to be modified, or the answer page may need to be optimized so that its content more closely matches the searcher’s question.
Regardless of the cause of the problem, when searchers say your site search has too many results, you do have a problem. The usability people are wrong if they insist that the number of results be reduced, but the technical folks are also wrong if they want to ignore what the users said because “Google has even more results and the users like Google.” Just because users don’t know how to express the problem doesn’t mean there is no problem. They are trying to tell you that the wrong results are at the top of your search results page and you need to respond.

  1. can you give an example of an algorithm, whick will give the possibility to sord the results, begining with most relevant ones? I’d be very thankful.

  2. Any search engine you have will include a relevance ranking algorithm. No single algorithm is best in all cases, but the best search engines allow ranking algorithms to be tuned, so that you can adjust which factors have more weight to improve the relevance for your site.
    Without knowing your site, it’s hard to know what to suggest, but a good algorithm for basic Web site search looks for the keywords in the title and the page text, boosting pages that mention the terms more. Pages that are selected in response to specific searches might subsequently be boosted for those searches. E-commerce searches might boost products with higher sales or higher profits.
    Your situation determines the best search ranking algorithm.
