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?

Rankings rise after improving internal linking - then drop again
I'm working on a large scale publishing site. I can increase search rankings almost immediately by improving internal linking to targeted pages, sometimes by 40 positions but after a day or two these same rankings drop down again, not always as low as before but significantly lower than their highest position. My theory is that the uplift generated by the internal linking is subsequently mitigated by other algorithmic factors relating to content quality or site performance or is this unlikely? Does anyone else have experience of this phenomenon or any theories?

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 😕

Newly designed page ranks in Google but then disappears - at a loss as to why.
Hi all, I wondered if you could help me at all please? We run a site called getinspired365.com (which is not optimised) and in the last 2 weeks have tried to optimise some new pages that we have added. For example, we have optimised this page - http://getinspired365.com/lifes-a-bit-like-mountaineering-never-look-down This page was added to Google's index via webmaster tools. When I then did a search for the full quote it came back 2nd in Google's search. If I did a search for half the quote (Life is a bit like mountaineering) it also ranked 2nd. We had another quote page that we'd optimised that displayed similar behaviour (it ranked 4th). But then for some reason when I now do the search it doesn't rank in the top 100 results. This, despite, an unoptimised "normal" page ranking 4th for a search such as: Thousands of geniuses live and die undiscovered. So our domain doesn't seem to be penalised as our "normal" pages are ranking. These pages aren't particularly well designed from an SEO standpoint. But our new pages - which are optimised - keep disappearing from Google, despite the fact they still show as indexed. I've rendered the pages and everything appears fine within Google Webmaster Tools. At a bit of a loss as to why they'd drop so significantly? A few pages I could understand but they've all but been removed. Any one seen this before, and any ideas what could be causing the issue? We have a different URL structure for our new pages in that we have the quote appear in the URL. All the content (bar the quote) that you see in the new pages are unique content that we've written ourselves. Could it be that we've over optimised and Google view these pages as spam? Many thanks in advance for all your help.

Does sharing same Business Name affect Google ranking?
Hey guys, We have been working for a client who is offering graphic design work almost 2 months. It is a new business and let's say the business name is ABC Graphic Design. So far all the pages are indexed, we built natural links through local directories, blog postings on relevant niche blogs and social media. We optimised the content and meta tags like we always do. However, none of the target keywords appear on the first 10 pages. This is quite odd considering we had a client who was doing the same business and we managed to show some progress in the first 2 months. We did some research and noticed that there are 2 ABC design websites with similar domain names and offering same services. They have nothing to do with my client and they are located in overseas. When i search ABC Graphic Design, the results show other companies instead of my client. My question is whether having a similar business name would affect the ranking. Obviously the other 2 websites have longer history and better ranking. Any suggestions?

Why Google isn't indexing my images?
Hello, on my fairly new website Worthminer.com I am noticing that Google is not indexing images from my sitemap. Already 560 images submitted and Google indexed only 3 of them. Altough there is more images indexed they are not indexing any new images, and I have no idea why. Posts, categories and other urls are indexing just fine, but images not. I am using Wordpress and for sitemaps Wordpress SEO by yoast. Am I missing something here? Why Google won't index my images? Thanks, I appreciate any help, David xv1GtwK.jpg

Best way to permanently remove URLs from the Google index?
We have several subdomains we use for testing applications. Even if we block with robots.txt, these subdomains still appear to get indexed (though they show as blocked by robots.txt. I've claimed these subdomains and requested permanent removal, but it appears that after a certain time period (6 months)? Google will re-index (and mark them as blocked by robots.txt). What is the best way to permanently remove these from the index? We can't use login to block because our clients want to be able to view these applications without needing to login. What is the next best solution?

De-indexed Link Directory
Howdy Guys, I'm currently working through our 4th reconsideration request and just have a couple of questions. Using Link Detox (www.linkresearchtools.com) new tool they have flagged up a 64 links that are Toxic and should be removed. After analysing them further alot / most of them are link directories that have now been de-indexed by Google. Do you think we should still ask for them to be removed or is this a pointless exercise as the links has already been removed because its been de-indexed. Would like your views on this guys.
