|What ranking factors must get lost by 301 Redirect?|
I know 301-redirects are common and basically recommended by Google.
We all know that a bit of the PR gets lost, but usually this shouldn't have any remarkable effect to the ranking.
Much more interesting in my eyes, but rarely discussed: What other factors must get lost, unavoidable? Some things take a lot of time, according to John Müller, but let's say we are patient webmaster. What ranking effecting "signals" cannot transferred to the new URL, even not on the long run?
Just Google knows?
I am not 100% sure this relates to what you are asking, but social media would be lost with a switch different URL. That might have some (secondary) effect?
Also, if you are moving one page (or a few pages) from one domain to another, then you need to be concerned about the effect the new domain will have on the pages.
Barry Schwartz (aka RustyBrick) asked John Mueller about sites escaping a penalty by moving content WITHOUT doing a 301 redirect, and john Mu seemed to imply that google could easily see the move without the 301 redirect and associate the new pages on the new site with the old site.
So to me, it seems that if a penalty could migrate without a 301 redirect, there is a possibility that there is some BENEFIT that could be passed along that is related to the history of the original domain (or the history of the owner or author), probably moreso with a proper 301 redirect.
just conjecture on my part though.
No tricks on my side.... but for example regarding technical URL-issues many webmaster use 301 where it may not always be the best solution.
Today I had the opportunity to ask John Müller from Google and he said:
Usually we try and succeed in transferring ALL ranking signals, except a bit of PR, which shouldn't effect your rankings remarkably.
I mentioned social signals and he said, that they still are no ranking signals. It's more a question of how social platforms deal with redirects than a question for Google.
IN THE MEANTIME Google is able to consider +1s when Domains change by 301. He doesn't know how others like FB deal with redirects, but supposed they will follow considering redirects in future.
Was this a google hangout?
If so, would love to see it (if you have a link).
Yes, but it was a german one.
Ach... das ist schade...
:) na dann....:

In this case could the attempt to escape a penalty also be interpreted as a webmaster simply trying to begin with a clean slate that does not carry the link baggage with it?

Yes, I think that is what Barry Schwartz was asking, really.

I wouldn't read too much into the answer than JohnMu gave because Barry was asking a completely different question to the answer JohnMu was providing.
