The Site Audit tool now detects WWW resolve issues!
Do you have “twin” domains? Find out with the Site Audit tool!
Now you will know if your WWW and non-WWW webpages have been duplicated and are competing for high positions in search results.
If your website has a WWW resolve issue, you will receive a notification reading “A domain name configured incorrectly.”

To check which pages are affected and tell bots to treat them as one page:
  • Use the Canonical meta tag to indicate which page is the main copy.
  • Apply a 301 redirect to transfer duplicate content pages to the preferred version.
  • Check your CMS (Content Management System). It can automatically generate multiple URL versions for each page.
Fix WWW resolve issues and accumulate both link juice and popularity for your main page!
