Why are bit.ly links being indexed and ranked by Google?
-
I did a quick search for "site:bit.ly" and it returns more than 10 million results.
Given that bit.ly links are 301 redirects, why are they being indexed in Google and ranked according to their destination?
I'm working on a similar project to bit.ly and I want to make sure I don't run into the same problem.
-
Given that Chrome and most header checkers (even older ones) are processing the 301s, I don't think a minor header difference would throw off Google's crawlers. They have to handle a lot.
I suspect it's more likely that either:
(a) There was a technical problem the last time they crawled (which would be impossible to see now, if it had been fixed).
(b) Some other signal is overwhelming or negating the 301 - such as massive direct links, canonicals, social, etc. That can be hard to measure.
I don't think it's worth getting hung up on the particulars of Bit.ly's index. I suspect many of these issues are unique to them. I also expect problems will expand with scale. What works for hundreds of pages may not work for millions, and Google isn't always great at massive-scale redirects.
-
Here's something more interesting.
Bitly vs tiny.cc
I used http://web-sniffer.net/ to grab the headers of both and with bitly links, I see an HTTP Response Header of 301, followed by "Content", but with tiny.cc links I only see the header redirect.
Two links I'm testing:
Bitly response:
Content (0.11 <acronym title="KibiByte = 1024 Byte">KiB</acronym>)
<title></span>bit.ly<span class="tag"></title> <a< span="">href="https://twitter.com/KPLU">moved here</a<>

I was getting 301->403 on SEO Book's header checker (http://tools.seobook.com/server-header-checker/), but I'm not seeing it on some other tools. Not worth getting hung up on, since it's 1 in 70M.
-
I wonder why you're seeing a 403, I still see a 200.

I show the second one (bit.ly/O6QkSI) redirecting to a 403.
Unfortunately, these are only anecdotes, and there's almost no way we could analyze the pattern across 70M indexed pages without a massive audit (and Bitly's cooperation). I don't see anything inherently wrong with their setup, and if you noticed that big of a jump (10M - 70M), it's definitely possible that something temporarily went wrong. In that case, it could take months for Google to clear out the index.
-
I looked at all 3 redirects and they all showed a single 301 redirect to a 200 destination for me. Do you recall which one was a 403?
Looking at my original comment in the question, last month bit.ly had 10M results and now I'm seeing 70M results, which means there was a [relatively] huge increase with indexed shortlinks.
I also see 1000+ results for "mz.cm" which doesn't seem much strange, since mz.cm is just a CNAME to the bitly platform.
I found another URL shortner which has activity, http://scr.im/ and I only saw the correct pages being indexed by Google, not the short links. I wonder if the indexing is particular to bitly and/or the IP subnet behind bitly links.
I looked at another one, bit.do, and their shortlinks are being indexed. Back to square 1.
-
One of those 301s to a 403, which is probably thwarting Google, but the other two seem like standard pages. Honestly, it's tough to do anything but speculate. It may be that so many people are linking to or sharing the short version that Google is choosing to ignore the redirect for ranking purposes (they don't honor signals as often as we like to think). It could simply be that some of them are fairly freshly created and haven't been processed correctly yet. It could be that these URLs got indexed when the target page was having problems (bad headers, down-time, etc.), and Google hasn't recrawled and refreshed those URLs.
I noticed that a lot of our "mz.cm" URLs (Moz's Bitly-powered short domain) seem to be indexed. In our case, it looks like we're chaining two 301s (because we made the domain move last year). It may be that something as small as that chain could throw off the crawlers, especially for links that aren't recrawled very often. I suspect that shortener URLs often get a big burst of activity and crawls early on (since that's the nature of social sharing) but then don't get refreshed very often.
Ultimately, on the scale of Bit.ly, a lot can happen. It may be that 70M URLs is barely a drop in the bucket for Bit.ly as well.
-
I spot checked a few and I noticed some are only single 301 redirects.
And looking at the results for site:bit.ly, some even have breadcrumbs ironically enough.
Here are a few examples
<cite class="_md">bit.ly/M5onJO</cite>
None of these should be indexed, but for some reason they are.
Presently I see 70M pages indexed for "bit.ly"
I see almost 600,000 results for "bitly.com"
-
It looks like bit.ly is chaining two 301s: the first one goes to feedproxy.google.com (FeedProxy is like AdSense for feeds, I think), and then the second 301 goes to the destination site. I suspect this intermediary may be part of the problem.
-
I wasn't sure on this one, but found this on readwrite.com.
"Bit.ly serves up links to Calais and gets back a list of the keywords and concepts that the linked-to pages are actually about. Think of it as machine-performed auto tagging with subject keywords. This structured data is much more interesting than the mere presence of search terms in a full text search."
Perhaps this structured data is submitted to Google?? Any other ideas?

Home Page Disappears From Google - But Rest of Site Still Ranked
As title suggests we are running into a serious issue of the home page disapearing from Google search results whilst the rest of the site still remains. We search for it naturally cannot find a trace, then use a "site:" command in Google and still the home page does not come up. We go into web masters and inspect the home page and even Google states that the page is indexable. We then run the "Request Indexing" and the site comes back on Google. This is having a damaging affect and we would like to understand why this issue is happening. Please note this is not happening on just one of our sites but has happened to three which are all located on the same server. One of our brand which has the issue is: www.henweekends.co.uk

Brand name not ranking in Google
Hi Moz'ers, Could you help me with something I cannot seem to figure out by myself. In June 2017 my company started a rebranding campaign. We've changed our brand name and launched a new website: https://spotler.com. Everything is going fine, but if you Google our brand name "Spotler" our website doesn't show up. How can it be? Our domain authority is 38. It would be wonderful if you could help me. Let me know if you need more information. Best, Simone

Wrong URLs indexed, Failing To Rank Anywhere
I’m struggling with a client website that's massively failing to rank. It was published in Nov/Dec last year - not optimised or ranking for anything, it's about 20 pages. I came onboard recently, and 5-6 weeks ago we added new content, did the on-page and finally changed from the non-www to the www version in htaccess and WP settings (while setting www as preferred in Search Console). We then did a press release and since then, have acquired about 4 partial match contextual links on good websites (before this, it had virtually none, save for social profiles etc.) I should note that just before we added the (about 50%) new content and optimised, my developer accidentally published the dev site of the old version of the site and it got indexed. He immediately added it correctly to robots.txt, and I assumed it would therefore drop out of the index fairly quickly and we need not be concerned. Now it's about 6 weeks later, and we’re still not ranking anywhere for our chosen keywords. The keywords are around “egg freezing,” so only moderate competition. We’re not even ranking for our brand name, which is 4 words long and pretty unique. We were ranking in the top 30 for this until yesterday, but it was the press release page on the old (non-www) URL! I was convinced we must have a duplicate content issue after realising the dev site was still indexed, so last week, we went into Search Console to remove all of the dev URLs manually from the index. The next day, they were all removed, and we suddenly began ranking (~83) for “freezing your eggs,” one of our keywords! This seemed unlikely to be a coincidence, but once again, the positive sign was dampened by the fact it was non-www page that was ranking, which made me wonder why the non-www pages were still even indexed. When I do site:oursite.com, for example, both non-www and www URLs are still showing up…. Can someone with more experience than me tell me whether I need to give up on this site, or what I could do to find out if I do? I feel like I may be wasting the client’s money here by building links to a site that could be under a very weird penalty 😕

Can too many NoFollow links damage your Google rankings?
I've been trying to recover from a Google algorithm change since Sep 2012, so far without success. I'm now wondering if the nofollow on external links in my blog posts are actually doing me damage. http://www.smartdatinguk.com/blog/ Does anyone have any experience of this?

Google Ranking Generally in Germany - Keywords & Umlauts
Hi Mozzers, I was hoping i could get some advice/opinions on a website ranking problem i have been working on, in particular one of the pages. This is our German language website which is hosted from Germany and a flaunt German speaking member of staff from our German office moderates the text content of the website for us.Our website seems to get good traffic ,visitor navigation and conversions. One of the keywords i focus building around is Schallpegelmessgerät which is one way of basically saying Sound level meter in German. The keyword uses an umlaut which i cannot use in the URL, but google is picking up and putting into the snippets, but apart from that our on-page optimization is good according to the moz tool. I have been trying to improve our content and we post many blog articles around the topic/keyword but google.de seems to choose not to even display this on the first couple of pages and sometimes ranks our blog articles around the third page. We are even been outranked by some low quality cheap online shop websites some of which with low quality content and low page and domain authorities. I had accepted this but after looking at bing.de and doing a search i find our page in the top 5 results, i understand that google and bing's algorhythms are different but just struggling to get my head around it all. Here is our website & page - http://www.cirrusresearch.de/produkte/schallpegelmessgerat/ Any advice on this situation would be greatly appreciated, thank you very much for reading this James

Google Not Indexing XML Sitemap Images
Hi Mozzers, We are having an issue with our XML sitemap images not being indexed. The site has over 39,000 pages and 17,500 images submitted in GWT. If you take a look at the attached screenshot, 'GWT Images - Not Indexed', you can see that the majority of the pages are being indexed - but none of the images are. The first thing you should know about the images is that they are hosted on a content delivery network (CDN), rather than on the site itself. However, Google advice suggests hosting on a CDN is fine - see second screenshot, 'Google CDN Advice'. That advice says to either (i) ensure the hosting site is verified in GWT or (ii) submit in robots.txt. As we can't verify the hosting site in GWT, we had opted to submit via robots.txt. There are 3 sitemap indexes: 1) http://www.greenplantswap.co.uk/sitemap_index.xml, 2) http://www.greenplantswap.co.uk/sitemap/plant_genera/listings.xml and 3) http://www.greenplantswap.co.uk/sitemap/plant_genera/plants.xml. Each sitemap index is split up into often hundreds or thousands of smaller XML sitemaps. This is necessary due to the size of the site and how we have decided to pull URLs in. Essentially, if we did it another way, it may have involved some of the sitemaps being massive and thus taking upwards of a minute to load. To give you an idea of what is being submitted to Google in one of the sitemaps, please see view-source:http://www.greenplantswap.co.uk/sitemap/plant_genera/4/listings.xml?page=1. Originally, the images were SSL, so we decided to reverted to non-SSL URLs as that was an easy change. But over a week later, that seems to have had no impact. The image URLs are ugly... but should this prevent them from being indexed? The strange thing is that a very small number of images have been indexed - see http://goo.gl/P8GMn. I don't know if this is an anomaly or whether it suggests no issue with how the images have been set up - thus, there may be another issue. Sorry for the long message but I would be extremely grateful for any insight into this. I have tried to offer as much information as I can, however please do let me know if this is not enough. Thank you for taking the time to read and help. Regards, Mark Oz6HzKO rYD3ICZ

Will changing Google Places address hurt rankings?
I have a client transferring ownership of their service business (photo booth rental). The current listed address will change, so my main concern is preserving the rankings during the transition. Should I change the Google Local listing to a new physical address, or change it to "serve a surrounding area"? It seems best to set as "serving a surrounding area", but I know Google is really weird about making local listing changes. I've seen and heard about countless listings falling completely off the map after being updated. Any advice appreciated.

Why am I not ranking in Google, but I am in Yahoo and Bing?
The website in question is: www.stbarthexclusives.com Our keywords are currently ranking for both Bing and Yahoo, but we're not appearing anywhere on Google. The website is being crawled successfully, but we still don't have any results. I hoping somebody can point me in the general right direction to fix/correct this problem. Additionally, there's a decent amount of "rel=canonical tags" on the website. If that helps your evaluation. Any advice would be greatly appreciated
