Google removes ‘Not Selected’ from Index Status
FWIW “not selected” is now removed (it wasn’t providing much value & confusing too many people), so you won’t be seeing fluctuations there anymore.John Mueller from Google has just confirmed that the “Not Selected” removal from Google Webmaster Tools was in fact intentional. The feature was confusing to webmasters, John says, and it sounds like it’s not coming back.
The graph above is taken from one of John’s Google+ posts where he attempted to explain the feature to curious webmasters saying:
“Here’s an example of the Webmaster Tools Index-Status graph for a site that started redirecting most of its URLs to a new domain recently. The rise in “not selected” shows that we’ve started picking up the redirect and have dropped the old URLs from our index.”
John repeatedly attempted to explain to concerned webmasters that this feature does not necessarily hint at website issues and poor quality signals:
“”Not selected” URLs aren’t bad — they’re just a sign that we crawled URLs that we feel aren’t necessary to index on their own. For example, that can happen when we find duplicates through URL structures or session-IDs. Having “not selected” URLs wouldn’t result in a lower ranking of those URLs that are indexed.”
It looks like it’s the constant questions about “Not Selected” were indicating that the feature was confusing webmasters while adding little value so it was removed.
I personally wish they’d kept it – any data they remove from us is a loss for visibility and transparency.
