Back in August of this year, while at Search Engine Strategies in San Jose, I sat in a session where one of the speakers talked about site search. He said something that I fundamentally disagree with but it got me thinking about why you should or should not implement a search feature on your own site.
I believe that implementing site search is smart for large sites, but only if you can be sure it works nearly perfectly. On the other hand, the speaker in this session (and I completely forget who it is) said that, for analytical purposes, every site should implement site search, even if it doesn't do a good job. This is what I fundamentally disagree with.
I'll agree that there is a wealth of information you can get from analyzing your site search usage, but I don't think it's wise to trade usability for data. Data is wonderful--and necessary--to help improve site usability, but data has to be more than just data, it has to be used to improve what's wrong with your site, not just get information.
According to this presenter, site search provides good keyword data, and it does. But if your site search blows you're doing yourself more harm than good, unless you're using your site search data specifically to help you improve your site search function.
When do you need site search and when should you forget about it?
The problem with site search on a lot of sites is that they often don't really work all that well. They'll produce good results for some searches but not for others. I've been on a number of sites testing their search only to find that there are "no matches" for exact searches on products they clearly sell. This is a problem.
When site search is available on large sites, people tend to use them. That's good. But if they search for something you have but the search doesn't find it, they'll assume you don't carry it. What do they do from there? They'll move on to the next site. That's bad.
If a site search can't produce the correct results, you're better off just removing it so your visitors will find it the old fashioned way--through navigation. At least this way you know they'll find what they want.
The first thing to look for in terms of making sure your site search is up to par, is making sure it returns results for products or services you carry. If the search can't find what is there, then either scrap it or fix it. Next, you need to make sure it produces relevant results for slightly incorrect searches. This is means that searching for "winter boots" will return results even if all your products are "snow boots".
This is where keyword research comes in handy (and, yes, site search analytic data, too!) You need to know all the different ways that people search for things that you offer. Then you need to test your site search to make sure it produces results for all the different ways people search for what you offer. Site search can't be so rigid that if something isn't described perfectly that it can't be found. Flexibility is key.
The minimum performance barrier
If you can get your site search to do those two things on a consistent basis then I'd say, go ahead and put it on your site. But, and this is crucial, always be working on improving it. This is where you can really use the analytical data you get from searches being performed. On a regular basis test as many searches as possible and see what the results are.
If you find more than 25% of searches produced incorrect results then you might need to pull your site search down and retool it some more. If you're getting less than 25% failed results then keep tweaking your search feature and eliminate the failures.
This should be a continuous process. Always test using your analytics data, test using keyword research, and test for any new products that are added.
A few other points about what your site search should be able to do. You want to be very accommodating to misspellings. If people are searching for specific product names it's easy to make a mistake and spell it incorrectly. Again, keep an eye on this with your analytics data. And finally, if you don't carry a certain product that was searched, your site search should produce results recommending similar products. Never leave your searchers empty handed.
