It is interesting to watch the varied reactions to the new Yahoo! search. As a spectator I can sit back and take it all in and form my own opinions. I can then apply my ideas to my clients and watch them succeed. One such topic of interest of late is Yahoo!'s policy on spam in the index.

To quote what Yahoo! considers unwanted:

"Some, but not all, examples of the more common types of pages that Yahoo! does not want included:

• Pages that harm accuracy, diversity or relevance of search results
• Pages dedicated to directing the user to another page
• Pages that have substantially the same content as other pages
• Sites with numerous, unnecessary virtual hostnames
• Pages in great quantity, automatically generated or of little value
• Pages using methods to artificially inflate search engine ranking
• The use of text that is hidden from the user
• Pages that give the search engine different content than what the end-user sees
• Excessively cross-linking sites to inflate a site's apparent popularity
• Pages built primarily for the search engines
• Misuse of competitor names
• Multiple sites offering the same content
• Pages that use excessive pop-ups, interfering with user navigation
• Pages that seem deceptive, fraudulent or provide a poor user experience
• Yahoo!'s Site Guidelines are designed to ensure that poor-quality pages do not degrade the user experience in any way."

As you can see, there is a lot of grey area here. While most points are pretty straight forward, some like "Pages in great quantity, automatically generated or of little value" could include dynamically generated database driven pages (like a storefront or e-commerce site) while "Excessively cross-linking sites to inflate a site's apparent popularity" could include sites which use legitimate link building strategies to help their rankings.

So what do you do? How do you know if your site falls into these categories? In other words, how do you determine if your site may be considered spam?

I would suggest taking a critical look at your site. Does it follow the guidelines listed in their help section on pages which Yahoo! does want included in its index? For example, are they original? Built for humans primarily? Contain useful information? These are all questions you need to keep in the back of your mind as you assess your site.

If you have concerns that perhaps you could be violating some of these rules, perhaps you need to look at what is needed to ensure you are in full compliance with Yahoo!'s recommendations. I would strongly suggest you do this review. If you do get removed from the index because of the spam policy it could be very difficult to get re-indexed according to Yahoo!'s own spam police.
