Search Engines for Hire

Good search results increase the overall usability of a Web site. But according to Laust Sondergaard, CEO of Mondosoft, "Most people don't realize that upwards of 75 percent of Web site visitors will abandon a site if it has poor search capabilities."

Picking the right search solution is an important decision. While free search engines like ht://dig are especially attractive to sites on a budget, many businesses prefer to partner with a search specialist offering commercial-grade support. Various commercial solutions are available for businesses with medium to large Web sites, intranets, extranets, or portals, including:

AltaVista (solutions.altavista.com). AltaVista created the first full-text search service. Today, its Search Engine 3.0 powers large sites for companies like TicketMaster, Amazon.com, Reuters, Buy.com, and Proctor & Gamble.

AskJeeves (business.ask.com/products). A pioneer in the natural language search space, AskJeeves' latest offering is its Answers 5.0 engine. It allows customized navigation via natural language queries and AskJeeves' patented popularity technology. Answers 5.0 is available in three editions: Standard, without customization options; Enterprise, with personalization and targeting features; and Global, with content localized in nine languages. An installation can be up and running in a few weeks, and starts at $100,000.

Atomz (www.atomz.com). Atomz.com Search lets customers add a search engine to any Web site with a few lines of HTML. This is unique in that it's the only hosted site search engine for e-commerce and personalized sites that can track and manage visitor sessions without special customization.

dtSearch (www.dtsearch.com). dtSearch is specifically designed for intranets, and offers an entire line of out-of-box search software. dtSearch Web powers large sites such as CodeHound.com and eMedicine.com, and includes programmable APIs that support multiple programming languages. The recently announced dtSearch Publish lets you publish Web sites with dtSearch on CDs and DVDs.

Inktomi (www.inktomi.com/products/search). Boasting customers like MSN Asia and Fujitsu Siemens Computers, Inktomi Search Software has been adopted by more than 2,000 enterprises, extranets, and entities to allow their users to search. Inktomi Search offers natural language search capabilities compatible with hundreds of file formats, and it has full Unicode support.

Mondosoft (www.mondosoft.com). Mondosoft MondoSearch 4.1 is a site search engine that presents results in customizable categories by relevance, language, and file data type (with graphic icons). It currently supports 12 languages. An optional addition, the Behavior Tracking Module, provides search usage logs in detail, such as what search terms visitors employ, and which search terms were used to find a given page. MondoSearch uses an internally developed database for its data repository, and its Behavior Tracking Module uses Microsoft's SQL Server.

Keeping an Eye on Privacy

Coping with COPPA
COPPA is the first privacy bill to come out of Washington. If your site collects personal data from children, make sure you understand the FTC compliance requirements.
Save Your Site from Spambots
Spambots spider the Web gathering email addresses. Use Apache's mod_rewrite module to protect your site from address scraping.
S T R A T E G Y :
Legal Code
Savvy users will see right through the escape clauses in your privacy policy. Bret A. Fausett has a better idea: Give them some protection, and get their business.

None of Your Business?
Don't make employees choose between getting paychecks and maintaining their privacy. According to Mimi Rosenheim, it's all about trust. Tell them what personal data you're collecting and make sure it's secure.
