New AddThis URL Sharing
-
So, AddThis just added a cool feature that attempts to track when people share URL's via cutting and pasting the address from the browser.
It appears to do so by adding a URL fragment on the end of the URL, hoping that the person sharing will cut and paste the entire thing. That seems like a reasonable assumption to me.
Unless I misunderstand, it seems like it will add a fragment to every URL (since it's trying to track all of 'em). Probably not a huge issue for the search engines when they crawl, as they'll, hopefully, discard the fragment, or discard the JS that appends the fragment.
But what about backlinks? Natural backlinks that someone might post to say, their blog, by doing exactly what AddThis is attempting to track - cutting and pasting the link.
What are people's thoughts on what will happen when this occurs, and the search engines crawl that link, fragment included?

Thanks, Ryan.

I am not sure why you received the malware alert. Here is a direct link to the video on viddler: http://www.viddler.com/explore/jpozadzides/videos/2/
I can share that I used TYNT. Every page of my content had a hash tag on it and I never saw a search result with a hashtag. I never saw any indication in GWMT that my site used hashtags.
Matt clearly says "Google takes a URL and truncates at the hashmark. If you have bla-bla-bla #3 and bla-bla-bla #4 those both get treated or canonicalized as the same URL"

Seems like Rand concurred back in 2009:
http://www.seomoz.org/blog/whiteboard-friday-using-the-hash
Useful stuff. About halfway down the comments on the above link Rand mentions needing specific analytics code to track things accurately. Anyone have experience with Google Analytics and # symbols?
By the way, Ryan, that link you posted is being flagged by Avast as containing malware. No idea if it's real or not.

I was just watching a Matt Cutts video from 2007. Yes, I know that would be considered the dark ages of SEO but I believe for this topic, the video has relevancy.
@22 minutes in Matt says when Google encounters a hashtag in a URL they truncate it.

The hash tags do not appear in the SERPs.

Hi Ryan,
Thanks for the response!
My interest isn't so much about visitors being able to follow the backlink or not, but how the SE's will index them. When a SE crawls a site with URL fragments, my experience has been that they do a good job discarding them.
What I'm seeing is two possibilities:
-
The SE's will discard the fragment when they crawl, and simply index the page as if it didn't have a fragment on the end, meaning a backlink with a fragment is identical to one without. Or,
-
They won't discard the fragment, and we'll end up with duplicates in the SERP's, which would, in part, be dealt with via a canonical tag.
It's great that you've used a similar service with TYNT.com Do you have any experience in how the SE's behave when crawling a link from TYNT and indexing that page?
Cheers.

This is nothing new to the web, just new to AddThis. TYNT.com offers this identical service. I have used them for some time but since I use AddThis for social sharing, it is more convenient for me to move this service to AddThis and eliminate one vendor.
The hashtag that is added to the end of URLs is there for tracking purposes. You can remove it or alter it, and you will still wind up on the exact same page. The hashtag has no effect on backlinks other then to track them.

Google Displaying Wrong Homepage URL
Hi Everyone, Google is displaying www.domain.com instead of domain.com. We have our preferred URL set up as domain.com, and even redirect www.domain.com to domain.com, but in the search results it is showing www.domain.com. Problem is we are seeing referral data from www.domain.com and in Google it says "No information is available for this page." Anyone seen a way to resolve this?

What is the fastest way disassociate an old URL with a new domain name?
We have a client with an old domain which was spammy (bad links). Until two months ago, it was forwarding to his current domain and (I believe) causing a penalty. Two months ago we transferred ownership of the spammy URL to a third party and setup an unrelated blog for Google to pick up on. Google did pick up on the URL. After two months Google Webmaster Tools is still showing 200 links from the old domain, to the new domain (from the spammy domain). Also, when you search the company name, the spammy domain still appears in the results (page two). Is there a faster way disassociate the old domain entirely from the business? I.e., just delete the domain, forward the domain to another website, etc.? If you have experience in this, I'd love to hear from you. Thanks!

Client wants to remove mobile URLs from their sitemap to avoid indexing issues. However this will require SEVERAL billing hours. Is having both mobile/desktop URLs in a sitemap really that detrimental to search indexing?
We had an enterprise client ask to remove mobile URLs from their sitemaps. For their website both desktop & mobile URLs are combined into one sitemap. Their website has a mobile template (not a responsive website) and is configured properly via Google's "separate URL" guidelines. Our client is referencing a statement made from John Mueller that having both mobile & desktop sitemaps can be problematic for indexing. Here is the article https://www.seroundtable.com/google-mobile-sitemaps-20137.html

We would be happy to remove the mobile URLs from their sitemap. However this will unfortunately take several billing hours for our development team to implement and QA. This will end up costing our client a great deal of money when the task is completed. Is it worth it to remove the mobile URLs from their main website to be in adherence to John Mueller's advice? We don't believe these extra mobile URLs are harming their search indexing. However we can't find any sources to explain otherwise. Any advice would be appreciated. Thx.0 -

New websites
Hi Moz community, My company updated and used a new developer to build and re-design their charity websites: www.runforcharity.com, www.cycleforcharity.com and www.sportforcharity.com. This sites were "re-launched" at the beggining of December 2015 and I have now been able to get a good 6 weeks worth of data. I've been religiously using Moz.com for a couple of years and I use it simply for SEO purposes. Our websites are built upon organic traffic being driven to them and I have noticed that the PA on the new sites has taken a hammering. They all appear to have a PA of 1 and I'm at a loss why? It appears that no page has h1 text? Would this be an issue with the developer or something the content team is doing wrong? Any help of advice would be much appreciated. Many thanks Ryan

Linking to URLs With Hash (#) in Them
How does link juice flow when linking to URLs with the hash tag in them? If I link to this page, which generates a pop-over on my homepage that gives info about my special offer, where will the link juice go to? homepage.com/#specialoffer Will the link juice go to the homepage? Will it go nowhere? Will it go to the hash URL above? I'd like to publish an annual/evergreen sort of offer that will generate lots of links. And instead of driving those links to homepage.com/offer, I was hoping to get that link juice to flow to the homepage, or maybe even a product page, instead. And just updating the pop over information each year as the offer changes. I've seen competitors do it this way but wanted to see what the community here things in terms of linking to URLs with the hash tag in them. Can also be a use case for using hash tags in URLs for tracking purposes maybe?

New URL Structure caused virtually All rankings to drop 5 to 10 positions in latest report ?.. Is this normal
Hi All, We changed out url structure on our website to both reduce both the size of our category url structure (reduce the number of layers '/ ' ) and also to replace the underscores we originally had to hyphens... We did this during a new site design. Anyway we relaunched it a week ago. We did the 301 redirects from old to new , new site maps etc, and the latest moz ranking report is showing most of them dropping 5 to 10 positions i.e from 3rd to 10th etc... Is this something to be expected , and then it should recover or should this be telling me alarm bells. I would have expected not such a negative shift in all my rankings ?.. Anyone thoughts of this would be greatly appreciated... thanks Pete .

Which URLs were indexed 2 years ago?
Hi, I hope anyone can help me with this issue. Our french domain experienced a huge drop of indexed URLs in 2012. More than 50k URLs were indexed, after the drop less than 10k were counted. I would like to check what happened here and which URLs were thrown out of the index. So I was thinking about a comparison between todays data and the data of 2012. Unfortunately we don't have any data on the indexed pages in 2012 beside the number of indexed pages. Is there any way to check, which URLs were indexed 2 years ago?
