Google’s John Mueller confirmed that utilizing a rel=exterior, rel=noopener and/or a rel=noreferrer haven’t any influence in your Google search rankings or search engine optimisation. John mentioned on Reddit that there’s “no impact” by including these hyperlink attributes to your hyperlinks.
The query on Reddit was “What impact do rel=”exterior” backlinks have on search engine optimisation?” John replied “No impact.” He then added that “some websites use it to show the hyperlink a bit otherwise (normally class=exterior although). Additionally rel=noopener & rel=noreferrer haven’t any search engine optimisation impact, they’re normally finished for safety / privateness causes. (Studying https://mathiasbynens.github.io/rel-noopener/ , apparently browsers now implicitly add rel=noopener robotically for hyperlinks that open in new tabs – TIL).”
You possibly can add loads of markup to your web site and hyperlinks however Google doesn’t help or use loads of it. For any markup you need to use and you have an interest in how Google makes use of it or not, it have to be listed within the Google Developer paperwork for it to be supported.
