Does 301 vs 302 matter when dealing with "social signal"?
-
When looking at links and how search engines look at "social signal," does it matter if a link is 301 vs 302?
In addition to that, if I build out my own short URL system that gets used for link redirects that include referral attributes, would/could I get penalized if I use 301 instead of 302?

Hi Robert,
Jonathan has said that nothing will be passed as parameters, but even if they were, I don't see that there would ever be a _penalty _for this (in the true sense of a penalty - algorithmic or manual penalisation for spam). You could flood Google with a million query strings and no canonicalisation if you did it badly which could get dangerous, is the only thing I can think of and even then, this would be easy to fix with canonicalisation on your own sites.

That's exactly what I'm looking at, thank you Jane.
@Robert, the "referral attributes" would not be passed through as parameters, but maybe as session data instead, therefor providing stronger SEO benefit.
Very thorough, thank you Jane

Jane,
Frankly, when I read your response I was a bit dismayed at myself. I think you zeroed in much better than anyone else did.
In his question Jonathan adds an interesting qualifier: "...own short URL system that gets used for link redirects that include referral attributes, would/could I get penalized if I use 301 instead of 302?" (italics are mine and are used to highlight the qualifier).
You state, "There would be no reason to penalise a URL shortener or its target URLs for this."
Don't you think that would be dependant on the "referral attributes" he is adding?
Best,
Robert

Hi Jonathan,
I think I understand what you're asking - you're asking if it matters for social signals if a link out from a social media website (be it Twitter, Facebook, Pinterest, etc.) goes through a 301 or a 302 redirect, e.g. a bit.ly link goes through one 301 to get to the target page, right?
Unfortunately, I don't know whether a 301 or 302 has any influence over how Google treats links from social media (which are usually also nofollowed, but we're talking purely about social signals here). I can only speculate that if I were Google and I wanted to look at social signals as opposed to SEO ranking signals, I would not take into account whether the redirect was a 301 or a 302.
If I were building my own tool to do this, I'd absolutely use 301s just because they are best practice for SEO, so you're going to get the benefit of the 301 if the link comes from somewhere other than a nofollowed social media site. There would be no reason to penalise a URL shortener or its target URLs for this.

Please provide an exact example of what you are trying to do, or planning to do. That will allow you to get much better advice.

I think Spencer answers this well. You also have to ask, what is the issue with social signals that you are worried about? The only application I could think of is you want to redirect, not pass link juice (like with a page with a lot of poor quality links) but want to maintain social signals to that url.
I am going to guess that the 302 would not work for passing social as well.
Best,

It's hard to understand exactly what you're asking but I'll try to answer anyways.
A 301 redirect is a permanent redirect and passes link juice.
A 302 redirect is a temporary redirect and does not pass link juice.
There are very few situations where you would use a 302 redirect instead of a 301 redirect. I've never advised anyone to use a 302.
Unless you're doing something manipulative I highly doubt you would be penalized for using a 301 redirect. Note that Bitly uses 301 redirects.
Here's a great Moz resource to check out on the topic of redirects.

Tricky 301 question
A friend has relaunched a website but his web guys (he didn't consult me!) didn't do any 301s and now traffic unsurprisingly has tanked. The old site and database no longer exists and there are now 2000+ 404's. Any ideas how to do the 301s from old urls to new product urls WITHOUT it being a massive manual job?

Pages are being dropped from index after a few days - AngularJS site serving "_escaped_fragment_"
My URL is: https://plentific.com/ Hi guys, About us: We are running an AngularJS SPA for property search.
Intermediate & Advanced SEO | | emre.kazan
Being an SPA and an entirely JavaScript application has proven to be an SEO nightmare, as you can imagine.
We are currently implementing the approach and serving an "escaped_fragment" version using PhantomJS.
Unfortunately, pre-rendering of the pages takes some time and even worse, on separate occasions the pre-rendering fails and the page appears to be empty. The problem: When I manually submit pages to Google, using the Fetch as Google tool, they get indexed and actually rank quite well for a few days and after that they just get dropped from the index.
Not getting lower in the rankings but totally dropped.
Even the Google cache returns a 404. The question: 1.) Could this be because of the whole serving an "escaped_fragment" version to the bots? (have in mind it is identical to the user visible one)? or 2.) Could this be because we are using an API to get our results leads to be considered "duplicate content" and that's why? And shouldn't this just result in lowering the SERP position instead of a drop? and 3.) Could this be a technical problem with us serving the content, or just Google does not trust sites served this way? Thank you very much! Pavel Velinov

Best to Post Dynamic Content (Listings) under "Posts" in Wordpress?
My commercial real estate web site is being migrated to Wordpress from Drupal. Is it advisable to place dynamic content that will use taxonomy under "Posts" ? Listings will be changed every few months and there could be anywhere from several hundred to several thousand of them on the site. Developers have given me different advice. One has been adamant that listings and neighborhood pages (there will be about 25 neighborhood pages) should not be in the post section which is to be strictly reserved for blog entries. The last thing I want is to create a site structure which is unfriendly to SEO!!!! I would very much appreciate the perspective of anyone proficient with Wordpress and SEO. Thanks!!!

How to get power tweets & Likes for social signals!
Hi, Just been looking into social signals a little deeper. From what I have read a tweet from one page is not the same as a tweet from another page, the authority and influence is also a big part. So a tweet from CNN does a lot more then a tweet from a random. So how do you find these authority and influential pages/users? I have come across Klout.com which gives a score out of 100, which is one way I guess BUT I have also noticed mozbar stats change for different facebook pages. Q: Can you use the mozbar on facebook & twitter pages to workout who will generate the best social signals? Cheers

What does "base" link mean here?
On http://www.google.com/support/webmasters/bin/answer.py?answer=139394, it says: rel="canonical" can be used with relative or absolute links, but we recommend using absolute links to minimize potential confusion or difficulties. If your document specifies a base link, any relative links will be relative to that base link. Where would a document specify a base link? And how?
