For quite some time Google has provided a keyword tool for advertisers with search volume represented by a green bar. While this green bar did help to indicate the popularity of a specific term, there was no way to know the actual number of searches.
Over the past few weeks I have seen accounts where some have reported seeing the introduction of actual search figures appearing along side the search volume green bar.
Barry Schwartz posted earlier this month at search engine land and referenced an adamap.com post and screenshot, but he was also unable to see the figures at that time. It appears as if Google is testing out the feature for consideration of a future roll-out.
Displaying the actual search figures rather than a general green bar will certainly make their tool more valuable to advertisers in the future. I for one welcome the release, whenever it may be.
