What does rel="nofollow me" do?

I notice on SO userpage all urls have rel="nofollow me" (i was thinking of putting nofollow on m开发者_如何学JAVAy site so i checked here to see what SO does). What does the 'me' part do?

This is a combination of two independent uses of the rel attribute.

• rel="nofollow" tells search engines to ignore the link when ranking pages.
• rel="me" is a microformat

rel="me" is a link from a page about a person to another page about the same person.

Basically Rel="nofollow" not to follow link or not share your website repo to that page. This page could be internal as well it could be external page. Rel="me" To give a social Repo to that page.

Rel="nofollow me" Means not to follow link but pass social repo to that page. Usually Facebook is a great example. From SEO point of view, now SEs are also considering social factors and I recommend to build your link on relevant page with high rate of traffic.

<a rel="me nofollow" href="https://example.org">

"me" instructs the search engines that the external website being linked(example.com) is another expression of me. The page where "me" appears and the destination website listed into the href field have the same owner.
