2 Questions about 301 Redirects
-
So I have a couple of questions about 301 redirects:
- Do Google penalties EVER pass through a 301? I've done 20+ domain 301s in the last year and have yet to see it happen, but the other day I read a an article (or maybe it was a QA post?) that suggested doing 302s to avoid transferring penalties. Has anyone seen any authoritative information regarding this?
- I 301'd a domain in February that another SEO firm had built a lot of spammy links and I began building contextual links for it at a very slow rate (like 10 or so a month). Within a month, my domain authority was a 26 on the new domain and my inbound links were non existent. By month 2, my links were 70k and domain authority was 34. By month 3, down to 25k inbound links and domain authority of 29, where it has settled for the last 3 months despite some really high quality links. My question (don't worry it's coming), is does anyone have any clue why my links shot up so quickly and then dropped? I'm assuming the 301 links kicked in and then only about 45% ended up 'sticking'??
Thanks in advance

Do Google penalties EVER pass through a 301?
Yes. 301 redirects make sure end users, search bots and link equity are passed to the new page. It is true though that not all link equity is passed with a 301, however good or bad it is passed. I have found this out with my own testing with clients as well as a few post i found on SEO round table and Google groups.
Does anyone have any clue why my links shot up so quickly and then dropped?
Where you tracking your external links use OSE? If so they crawl a different amount of domains and URLs each time they update their index so chances are you are looking at different data sets each time.

1. In a hangout two or three months ago, John Mueller said that 301s can pass a penalty. Whether or not a 302 will do so as well, I don't know, but I'd be hesitant to bet on them not doing so. We've never tried redirecting in a penalty situation. I have spoken to some colleagues, however, that say they've had clients come to them that had 301'd and the penalty showed up on a new domain shortly thereafter.
2. Did your drop-off happen to coincide with a Penguin update? At one time, Matt C. had said that the results of cleaning up a link profile wouldn't really come into play until the next update (for an algorithmic slap). But others and I have seen instances in which that seems to no longer always be the case - 2 weeks to two months, with no update, is showing evidence of removed dampening.

Mobile Redirect - Cloaking/Sneaky?
Question since Google is somewhat vague on what they consider mobile "equivalent" content. This is the hand we're dealt with due to budget, no m.dot, etc, responsive/dynamic is on the roadmap but still a couple quarters away but, for now, here's the situation. We have two sets of content and experiences, one for desktop and one for mobile. The problem is that desktop content does not = mobile content. The layout, user experience, images and copy aren't the same across both versions - they are not dramatically different but not identical. In many cases, no mobile equivalent exists. Dev wants to redirect visitors who find the desktop version in mobile search to the equivalent mobile experience, when it exists, when it doesn't they want to redirect to the mobile homepage - which really isn't a homepage it's an unfiltered view of the content. Yeah we have push state in place for the mobile version etc. My concern is that Google will look at this as cloaking, maybe not in the cases where there's a near equivalent piece of content, but definitely when we're redirecting to the "homepage". Not to mention this isn't a great user experience and will impact conversion/engagement metrics which are likely factors Google's algorithm considers. What's the MOZ Community say about this? Cloaking or Not and Why? Thanks!

Moving website and domain name without 301 Redirect or rel=canonical
I do not wish to draw attention to my company, so I am using code names. For the sake of this discussion, we are a new car dealership representing Brand X Cars. The manufacturer of Brand X Cars pushes its dealers toward a website hosting company called CarWebsites in order to maintain a level of quality and control with each dealer. However, we have found the platform to be too restricting, and are switching to our own WordPress site. Unfortunately Brand X is claiming ownership of our original domain, BrandXCarDealer.net, so we have switched to BrandXCarDealer.com (which we prefer anyways). Now both websites are running, and there is duplicate content of everything. Brand X is not cooperative and will not 301 redirect to the new site, and we do not have access to the of the website for a rel=canonical. Brand X is also dragging its feet on shutting down BrandXCarDealer.net. We do still have access to change the content of the pages on the BrandXCarDealer.net site, but that is pretty much as far as our control goes. So my question is, is there anything we can do, without using a 301 redirect or rel=canonical, to tell Google to pay attention to the new BrandXCarDealer.com rather than the old BrandXCarDealer.net? Any suggestions are appreciated. Thanks!

What is the difference between rel canonical and 301's?
Hi Guys I have been told a few times to add the rel canonical tag to my category pages - however every category page actually is different from the other - besides the listings that I have for my staff on each pages. Some of them specialise in areas that cross over in other areas - but over really if I'm re directing for eg: Psychic Readings over to Love and Relationships because 5 of my staff members are in both categories - the actual delivering of content and in depth of the actual category which skills are provided at different levels don't justify me creating a rel tag from Psychic Readings over to Love and Relationships just because i have 5 staff members listed under both categories. Tell me have I got this right or completely wrong? Here is an eg: Psychic Readings category https://www.zenory.com/psychic-readings And love and relationships category - https://www.zenory.com/love-relationships Hope this makes sense - I really look forward to your guys feedback! Cheers

G.A. question - removing a specific page's data from total site's results?
I hope I can explain this clearly, hang in there! One of the clients of the law firm I work for does some SEO work for the firm and one thing he has been doing is googling a certain keyword over and over again to trick google's auto fill into using that keyword. When he runs his program he generates around 500 hits to one of our attorney's bio pages. This happens once or twice a week, and since I don't consider them real organic traffic it has been really messing up my GA reports. Is there a way to block that landing page from my overall reports? Or is there a better way to deal with the skewed data? Any help or advice is appreciated, I am still so new to SEO I feel like a lot of my questions are obvious, but please go easy on me!

Suspicious external links to site have 302 redirects
Hi, I have been asked to look at a site where I suspect some questionable SEO work, particularly link building. The site does seem to be performing very poorly in Google since January 2014, although there are no messages in WMT. Using WMT, OPenSiteExplorer, Majestic & NetPeak, I have analysed inbound links and found a group of links which although are listed in WMT, etc appear to 302 redirect to a directory in China (therefore the actual linking domain is not visible). It looks like a crude type of link farm, but I cant understand why they would use 302s not 301s. The domains are not visible due to redirects. Should I request a disavow or ignore? The linking domains are listed below: http://www.basalts.cn/

URL Shortners Question
Does anyone know if there are any URL shortners that track when googlebot visits them? I want to know when googlebot visits a shortened link that does NOT got to a URL I control. Any ideas would be much appreciated.

Buying a website and redirecting everything
We are considering purchasing an existing website in our industry with a domain authority of 52 and 20K inlinks and redirecting it to our new website with a domain authority of 26 and 1,000 inlinks. Would this be the best way to improve our new site's authority and inlinks? Would Google penalize us for doing that or would it effectively transfer the old sites authority to us?
