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.
