I reported at the Search Engine Roundtable that the Overture Keyword Suggestion Tool no longer takes you to the tool; instead, it redirects you to the Yahoo Search Marketing landing page. I emailed Yahoo for a statement, and they have confirmed that they have decommissioned the tool.
There are tools you can use within the Yahoo Search Marketing console that you can use instead, but it requires that you login. The Overture tool has been plagued with issues for a long time. Overture’s tool, to me, is a historic SEM tool that will forever be remembered amongst SEMs – it is a bit sad to me to see it go. There are many good alternatives that are much better then the Overture tool. For more, see our Search Marketing: Search Term Research category.
