Google Confirms No Loss in Link Authority on HTTPS Implementation

In what should help satisfy a question on the minds of a lot of SEOs — Google’s John Mueller has confirmed via a comment on Google+ there’s no loss in link authority when moving from HTTP to HTTPS.


This comes as a response to the recent news that Google will now default to indexing HTTPS pages when a duplicate HTTP version also exists.

Understandably, that led to some concern over whether or not link authority would be lost as a result of inbound links to HTTP pages no longer being counted. Now we have the answer, and the answer is no.

This was again confirmed on Twitter by Google’s Gary Illyes after SEJ’s Brent Csutoras reached out for clarification.

Google will count the collective signals from inbound links pointing to both the HTTP and HTTPS versions of a page. Moreover, this will be done automatically, so there’s no need to worry about redirects.

A huge question on people’s minds has been answered by two top executives at Google. Go ahead and move to HTTPS without worrying about loss of link signals. You may even get a rankings boost from it in the process.

Google’s Gary Illyes provided more insight in a Facebook comment on this story, stating that it’s a priority for the company to make site moves easier in the near future, especially when it comes to 301 redirects:

    Glad to see they;
    a) opted to answer it
    b) decided to do the right thing the right way

    Don’t simply rush off to implement HTTPS/SSL – you need to double check everything first.
    1) Make sure you don’t cause conflicts by having an HTTPS page requesting non-HTTPS resources (I believe this can cause some browsers to throw a warning)
    2) Certain 3rd party resources/functions may hit issues due to URL based referencing (such as Disqus comments may go haywire :D).

    So look and think before you leap.

  • Claire Greenhow

    I noticed a significant drop when I made the move earlier in the year but slowly the old links seem to be getting picked up and sorted out.

    I don’t know whether it is harmful in shifting from HTTP to HTTPS.

      Shifting from HTTP to HTTPS won’t be harmful, SEO-wise. As stated on the news, the link authority you got while your site is still on HTTP won’t be loss when you implement HTTPS. Plus, Google favors HTTPS sites.
