Our last post on the impact of Google’s encrypted search change left us with data up to November 2nd and with an average of 6.5% of sites’ Google natural search traffic labeled (not provided.) Since then, Rand Fishkin at SEOMoz published data showing sites surveyed had an average of 12% of Google natural search traffic (not provided) in the week of Nov. 4 – Nov. 10th. Brian Whalley at Hubspot recently updated that an average of 11.36% traffic was (not provided) for Hubspot customers.
Our original look was at 5 high traffic websites – 2 online retailers, 3 service providers – more than 1.7 million visits in total. We updated the data to include up to Nov 20th and today, we are giving you a view both averaged week over week and day over day by website.
The percentage of traffic (not provided) grew from less than 1% in the week immediately after the launch, to 8.875% of traffic from Nov. 18-Nov. 20th (although not a full week.)
Looking at the five websites day over day, the site (site 5) with the most traffic lost to (not provided) peaked at 14% on November 17. One of the five sites (site 2) lost consistently less traffic than the others, averaging 3.4% in the week between Nov. 14-Nov 20th, compared to a 10.84% for all other sites in the same time period.
