Making sure that your search engine helps it be as easy as possible to your customers to find what they are looking for is business-critical. It is also quite hard – very good search engines can cost an awful lot of money and demand a lot of continual effort to keep them about scratch.

As an example: in Monday 12th December 2006, I wanted to buy a copy of Jamie Oliver’s new make book Jamie’s Italy coming from. So , I just went to the “Books” section of their website and searched for “olivers italy” and these 9 items appeared on the results page:

1 . “The American Tractor” by Meat W. Ertel 2 . “A Garden in Lucca: Obtaining Paradise in Tuscany” simply by Paul Gervais 3. “History in Exile: Memory and Identity on the Borders with the Balkans” simply by Pamela Ballinger 4. “Oliver Tractors” by simply Jeff Hackett, Mike Schaefer 5. “Wyoming (Moon Handbooks S. )” by Put on Pitcher 6. “Wines of Australia (Mitchell Beazley Wine beverages Guides)” simply by James Halliday 7. “All Music Tips for Jazz: The Definitive Tips for Jazz Music” by Ron Wynn (Editor), et al. 8. “Larousse Gastronomique: The World’s Greatest Cookery Encyclopedia” by Succeed Montagne being unfaithful. “The Teacher’s Calendar: The Day-By-Day Directory to Holiday seasons, Historical Events, Birthdays and Special Days and nights, Weeks and Months” by simply Holly McGuire (Compiler), ainsi que al.

Jamie Oliver’s book did not appear anywhere on the effects page, even though it had been Amazon’s 3rd best-selling book in the earlier 24 hours.

The problem was that I had tapped out “olivers italy”, instead of “oliver’s italy” (which would have go back Jamie Oliver’s at the top of the search results list). That solitary missing bruit was the only thing that it took to get Amazon’s costly search engine to splutter, fall over and fail.

Hence – in the event that Amazon cannot do it, it ought to be impossible, correct?

Wrong – here are several things the boys & girls by Amazon may – and should – include thought about.

Two types of problems

There are two basic types of issues that a user can easily experience when searching for some thing:

– User-error – the correct search phrase is accessed incorrectly (i. e. the consumer intends to a search term that would cause the search engine to return results which have been relevant to the requirements, but they enter it incorrectly). — Search engine problem – the wrong search term is entered (i. e. the user enters a search term that your search engine will not relate to their particular needs).

User error

People generally your correct key phrase incorrectly because they either:

— Don’t know ways to spell it. – Have made a keying in error

It’s important to find out that there are an incredible number of potential customers so, who can’t mean very well. For instance , a the year 2003 survey on the literacy (i. e. studying and writing) estimated that there were 16% of English language adults (aged 16 to 65-year-olds) experienced literacy levels no above those anticipated of an 13 year-old (source: The Skills for lifetime Survey).

Also, a few not forget that according to the British Dyslexia Relationship around 4% of the population are greatly dyslexic and a further 6% have slight to average dyslexia challenges.

Because of this your search engine has to represent people producing basic knowledge-based spelling errors.

Your engine also need to account for folks who know how to mean what they are trying to find, but generate typing problems. The main categories of typing error are:

– Personalities close to one other on the key pad being moved into erroneously (either in place of – or additionally to — the correct letter). For example: wrong/wring; for/dfor. – Characters staying omitted. As an illustration: missing/missng; oliver’s/olivers. – Individuals being came into too many circumstances. For example: impossible/imposssible. – People being moved into in the incorrect order. Including: disaply/display; being/ebing.

Your engine will need to allow visitors to make these mistakes and still return beneficial and relevant results.

Even though we now have named these kind of issues? End user error’, when your search engine fails to return data that the user is seeking it is, of course , your problem and not theirs!

Search results error

When people enter the wrong term into a search results, it is only incorrect because you may have not anticipated it. You must aim to cover as many bases and foresee as many varied search terms as is possible.

What to do

The next steps to make your search engine perform better are really basic:

— Sit down and make a list of all spelling mistakes, typing problems and alternate search terms that you think could possibly be relevant to your webblog (e. g. actually check out your keyboard and think about what letters happen to be close to you another). — Ask others in your organisation to make similar lists. — Do some research into what search terms people are using on your own site (e. g. interviews, questionnaires, look at your search engine records, etc . ) – Apply everything you discover how to your search engine.

And that’s it. You now have the knowledge you need to begin improving your site’s search engine.

Other thoughts

– Improvements in word processing software have made people lazy typists. Software that auto-corrects a large number of spelling and typing problems means that people are no longer forced to review and correct their operate to the same extent as in the past. Which means many people are stepping out of the behavior of specific spelling/typing. Therefore , when they transfer of an auto-correcting environment (and onto a site, for example) they are very likely to make – and less vulnerable to notice/correct — mistakes!

– Listings pages ought to display the search term the user entered in large text (e. g. 28pt). This may help people area any inadvertent errors. Search engine pages should also provide the telephone quantities for consumer enquiries/assistance.
