The Google Adwords Keyword Tool seemed to have a bug of sorts, as was noted by SEO Consult’s blog and other SEOs too, leading to discussions starting a week earlier on AdWords help forums too.
The problem was that the tool was reporting ZERO volume for a large number of keywords, when using the Exact Match match type.
Google also acknowledged the issue, as has been quoted, “We’re aware of a potential issue that is affecting the keyword tool in AdWords, and are working hard to fix it.” A random selection of keywords were reporting zero for volume and mostly head and middle tail were affected at both global and local volumes.
But it seems Google has got rid of the bug in the keyword tool, and a search for 'wine' in exact phrase is showing the numbers as earlier.
