Organic vs PPC vs Paid Inclusion

Many search engines had to find new revenue streams as the dot com bubble burst and targeted pay per click text ads provided that stream.

Yahoo! also has a paid inclusion program which is said to ensure coverage but not to have any effect on relevancy. Listing in their paid inclusion does get your site a human review though, so it may help improve your relevancy scores some.

1. Regular organic traffic: Organic search results are the free results off to the left side of the page.

2. Pay per click ads: Pay Per Click ads are usually at the right side of the page. Some search engines also place a few at the top & bottom of pages. Typically PPC ads in most search engines (such as Google, MSN, and Yahoo!) are above or below the search results are in a colored box. AOL and Ask Jeeves do not make it as easy to distinguish their paid listings though.

3. Paid inclusion: Paid inclusion sites list in the regular organic listings but paid inclusion is said to have no effect on relevancy. They are blended into the search results and can not be easily distinguished from the other search results.

AltaVista was known to have a problem with mixing paid inclusion and organic ads for a while. Google feels paid inclusion is a conflict of interests with relevancy and has never had a paid inclusion program.

    Hi there 

    Why do dogs eat their poop? One reason dogs eat their poop is because it just plain taste
    good. Another reason is it could be a vitamin deficiency. One other reason for the poop
    eating is that it is an instinctual behavior in the wild to eat the poop to keep other predators
    from tracking their movements.

    Some solutions for stopping poop eating are: You can put meat tenderizer on it.

    What do you think?

    Wow, I've found the same to be true too!  How did you find that?  

    Bye, bye - Wendy!
