What happened?: For about a year now, Google has been stepping up its efforts to make the collection of search results harder. The biggest impact came from dropping the num=100 parameter in September 2025, but there have been smaller and larger changes to how search results are delivered almost every week since then. The latest one: Google routes clicks through redirect URLs of the form google.com/goto, so the target URL is no longer part of the search result itself and only becomes visible when the redirect is followed. We have been observing this on a small scale for several weeks. Google is now rolling it out broadly and confirmed the change to Search Engine Roundtable.
Impact on SISTRIX: The change affects all providers who collect and analyse search results. Without a countermeasure, affected results would carry no target domain and could not be attributed to a website. We already resolve these redirect URLs back to their real targets, and we are now scaling that up to cover all affected results. Every resolved URL costs an additional request against Google, which makes the collection of search results more complex and more expensive. As with num=100, it does not prevent it.
Our approach: We are scaling up the resolution of masked URLs and monitoring how far the rollout extends. While we do this, we expect update cycles to be somewhat slower than usual over the next few days. The data itself remains complete and comparable. Our goal is to be back to the usual rhythm shortly, and we will post an update here as things develop. As with the changes of the past months, this will remain an ongoing process rather than a one time fix.
