With the new Search Analytics API, it's now time to gradually say goodbye to the old CSV download scripts for information on queries & rankings. We'll be turning off access to these downloads on October 20, 2015.
These download scripts have helped various sites & tools to get information on queries, impressions, clicks, and rankings over the years. However, they didn't use the new Search Analytics data, and relied on the deprecated Client Login API.
Farewell, CSV downloads, you've served us (and many webmasters!) well, but it's time to move on. We're already seeing lots of usage with the new API. Are you already doing something neat with the API? Let us know in the comments!
