Below is a chart of the ASCII character set:
The majority of the time the Open Directory Project ranks its directory listings alphanumerically. However I have noticed that in many categories the editor has decided to ignore all the characters preceding the first alphabetical character.
For example, "#1 Free Clip Art" is a listing title in the directory. But the #1 part of the title is ignored in ranking the listings. The rank is based on the first letter of the revised title, Free Clip Art, which is F.
Unlike the Open Directory Project, Yahoo! takes into account all characters in the listing title in its rankings. Therefore, the listing, "#1 Vacations, Cruises & Giveaways" ("#" is #35 in the ASCII chart) ranks above, "1 Above All Resorts.com" ("1" is #49 in the ASCII chart).
Once upon a time Yahoo! extracted its web search results from its web directory. This is no longer the case after Yahoo! replaced its old search results with Google powered listings, which are ranked by relevance, not alphanumerically.
As a result, the Yahoo! Directory now refers far fewer visitors than before. So I think web marketers who register domain names to take advantage of alphanumerical ranked listings in Yahoo! are now mostly wasting their time.
To do this place the following code in between the HEAD section:
Some servers may not recognize the ".js" file type. If that is the case with your server, contact your hosting company and ask them to add the following line to the "mime.types" file in the server's config directory, and then restart the server.
The first solution is probably more convenient to use. But both solutions work just as well.
