UPDATE: Keyword Unmapping Postponed
We recently notified you about a change to the way we “map” keywords for the Standard match type. A limited number of synonyms that are currently mapped in your account will be unmapped in the near future. The original launch date that was communicated, July 29th, has been postponed by a few days.

We will notify you shortly after the launch so that you can begin uploading new terms. If you have any questions regarding this change, please contact us.

———————————-

Today we received a an email from Yahoo concerning one of our search accounts. Yahoo is going to be implementing keyword changes July 29th 2008. Here’s the email in its entirety:

We wanted to let you know that a limited number of keywords in your account that are currently linked to synonyms, or “mapped,” will soon become unmapped to give you more control over your keywords. As you may know, we use various matching technologies to link some bidded keywords to other terms that a searcher might use synonymously to look for them. This mapping connects some keywords with related synonyms, such as “car insurance” with “auto insurance.”

What does this mean for your account?
You may still receive traffic for these terms through the Advanced match type even after these terms are unmapped. For better control, however, we suggest adding these “new” terms to your existing account, along with new bids and ads. If you choose to add the new terms, keep in mind that they will be rejected as duplicates prior to July 29, if you are adding to the same ad group as your existing bidded term.

This seems like a good thing, the more control we have over our terms and their individual bids the more valuable our campaign. Yahoo has certainly taken a lot of heat recently from the industry including myself but this seems like a smart move. Please don’t stop here Yahoo!

Here’s the keyword that was mapped and its new terms via the email from Yahoo. I don’t think i’m giving away any secrets by posting this
