The Impact of Attribute REV in SEO

[webg]

Hi,

I'm looking for information about rev="" attribute in SEO. What do this attribute communicate to search robots?

Does it Impacts in the positioning of pages / keywords?

Does anyone have information that could help me?

It will communicate that the relationship between the linked document and the current document. It's reverse of the rel attribute. Browsers do not use the attribute, but search engines can learn more about the relationship, such as: glossary, index, chapter, subsection and appendix.

I understand that it is used as an indicator of what the page is from the domain.

But my question is if the search robots "get score" on what is filled.

Exemplos:

1. text

rev=”Vote-for”
rev=”Vote-abstain”
rev=”Vote-against”

So I ask: The examples above, do they influence positively or negatively to the external page or page that is using these parameters?

2. [In cases that the client uses this example above, filling the rev attribute to add event markers from GA.  May have some interference for robots or else for the positioning of the page in search results?

3. If it not influence on the points mentioned, interference may be negative / positive at in some time?](http://www.site.com)
