Less than a month after announcing its Search Analytics API, Google has now stated that "it's now time to gradually say goodbye to the old CSV download scripts for information on queries and rankings." Google will keep the script downloads available for a bit longer, but will turn off access for good on October 20, 2015. Google recognized the benefit the downloads have brought users over the years, but the technology underlying the scripts has been replaced with the Search Analytics API and it's time to move on.
"These download scripts have helped various sites & tools get information on queries, impressions, clicks, and rankings over the years," John Mueller, Google Webmaster Trends Analyst, commented on a blog announcement. "However, they didn't use the new Search Analytics data, and relied on the deprecated Client Login API."
The short time frame between announcement and action (less than two months) suggests that Google has seen positive adoption of its Search Analytics API. Mueller confirmed in his blog announcement. He mentioned "lots of usage" and encouraged those using the API to let Google know what they are developing in the comments section of the blog post. Change is seldom easy, so reactions have been mixed. But, integrations with a deprecated API is never a suggested development route.
In the Search Analytics announcement, Mueller commented that the Search Analytics API should be easy to adjust to for anyone who has used any of Google's other APIs or one of the Search Console APIs. The newer API verifies data presence, click count, top pages, top queries, top mobile queries, and more.
