I recently overhauled a website for a client. Their preference was to switch from a www url to a non-www url as part of the redesign.

Once we launched the site, it took a major plummet in its position on SERPs. Now, I know this could be for several reasons outside of the projected issue I presented. But has anyone else ever made a similar switch and saw their website take a decline on SERPs?

Thanks in advance for your comments.

  • Do you redirect with a 301 header? If not, there ya go :)

  • You have both www and non-www properties verified in GSC and both have seen a "plummet in SEO"? And by "plummet in SEO" are you solely referring to your apparent position in the SERPs? What about the number of visitors?

  • Whenever you make a change like this, there is a fairly significant disruption. Www versus non-www are two different sites. Martijn makes a good point. Make sure that www redirects to non-www. Otherwise, you will just have to wait. It will work out.

  • Possible duplicate of SEO preference for www or no-www, does a site with one rank better than the other?

  • @marcanuy this is not exactly a duplicate of that question. That question is asking for an opinion on www vs. non-www. This one is asking for possible problem & solution they might have missed during the switch from www to non-www.
