How to deal with old, indexed hashbang URLs?
-
I inherited a site that used to be in Flash and used hashbang URLs (i.e. www.example.com/#!page-name-here). We're now off of Flash and have a "normal" URL structure that looks something like this: www.example.com/page-name-here
Here's the problem: Google still has thousands of the old hashbang (#!) URLs in its index. These URLs still work because the web server doesn't actually read anything that comes after the hash. So, when the web server sees this URL www.example.com/#!page-name-here, it basically renders this page www.example.com/# while keeping the full URL structure intact (www.example.com/#!page-name-here). Hopefully, that makes sense. So, in Google you'll see this URL indexed (www.example.com/#!page-name-here), but if you click it you essentially are taken to our homepage content (even though the URL isn't exactly the canonical homepage URL...which s/b www.example.com/).
My big fear here is a duplicate content penalty for our homepage. Essentially, I'm afraid that Google is seeing thousands of versions of our homepage. Even though the hashbang URLs are different, the content (ie. title, meta descrip, page content) is exactly the same for all of them. Obviously, this is a typical SEO no-no. And, I've recently seen the homepage drop like a rock for a search of our brand name which has ranked #1 for months. Now, admittedly we've made a bunch of changes during this whole site migration, but this #! URL problem just bothers me. I think it could be a major cause of our homepage tanking for brand queries.
So, why not just 301 redirect all of the #! URLs? Well, the server won't accept traditional 301s for the #! URLs because the # seems to screw everything up (server doesn't acknowledge what comes after the #).
I "think" our only option here is to try and add some 301 redirects via Javascript. Yeah, I know that spiders have a love/hate (well, mostly hate) relationship w/ Javascript, but I think that's our only resort.....unless, someone here has a better way?
If you've dealt with hashbang URLs before, I'd LOVE to hear your advice on how to deal w/ this issue.
Best,

Celts,
Did you ever resolve this? What you were discussing back in 2012 is called a "hashbang", and you can learn more about it here on Google. It is technically a way to get AJAX-loaded pages indexed on their own URL.
You asked this question a couple of years ago, and things have changed since then with push states and HTML 5 being preferred over hashbangs, and not loading a page's content with AJAX still the recommendation when possible.

Thanks for your answer. Yeah, I've seen the hash tag function as you've described it when being used for named anchors. However, in my case, Google IS indexing the URLs that contain the #! and it is also grabbing my homepage's title and using it in the SERPs on those results. So, given that that's happening, I'm concerned that the #! IS hurting me in this case.
In thinking more about this, I think what I'll do is put a canonical tag on the homepage and that should hopefully provide the extra guidance/insurance that I need to tell spiders that there is only ONE version of the homepage.

Google ignores the hash tag when indexing URLs. You can offer your home page with various versions of hash tags appended to the end of the URL and Google will not mind a bit. It will not case any issue for SEO.
A few more notes:
- Hash tags are used in HTML as an onpage anchor. Wikipedia is a good example. Take a look at the following page: http://en.wikipedia.org/wiki/Guitar. If you hover over the HISTORY link in the Table of Contents at the top of the page, notice the URL for the HISTORY link is http://en.wikipedia.org/wiki/Guitar#History. When you click the link, you remain on the same page but move to the History part of the page.
If you search Google.com for "Guitar History" you will notice the WIki page is listed first. (see attachment). The URL offered by Google is the page URL without any hash tag. Google does offer the ability to "Jump to History" which includes the hash tag link. That is a benefit to using anchor text on a page. Otherwise Google does not take the hash tag nor anything after it into account when indexing pages.
Rand offers a short video on this exact topic: http://www.seomoz.org/blog/whiteboard-friday-using-the-hash
I am not familiar with the exclamation point (bang) being used after the hash tag outside of twitter. The standard twitter URLs use it.
Summary - the hash bag is not the reason for your recent drop in rankings.
I am unclear what you mean by "Google still has thousands of the old hashbang (#!) URLs in its index." Can you share an example?

Why is page still indexing?
Hi all, I have a few pages that - despite having a robots meta tag and no follow, no index, they are showing up in Google SERPs. In troubleshooting this with my team, it was brought up that another page could be linking to these pages and causing this. Is that plausible? How could I confirm that? Thanks,

No-index pages with duplicate content?
Hello, I have an e-commerce website selling about 20 000 different products. For the most used of those products, I created unique high quality content. The content has been written by a professional player that describes how and why those are useful which is of huge interest to buyers. It would cost too much to write that high quality content for 20 000 different products, but we still have to sell them. Therefore, our idea was to no-index the products that only have the same copy-paste descriptions all other websites have. Do you think it's better to do that or to just let everything indexed normally since we might get search traffic from those pages? Thanks a lot for your help!

Removing old versions of a page.
Recently one of my good friends updated his iweb based screen printing site to wordpress per my recommendation. This update has helped dramatically boost his rankings to #3 for most local keywords. This new site is now V5 of his site, but all older iweb versions are still on the ftp. There are a total of 209 pages on the ftp, as versions of about 30 actual pages. The pages have changed significantly with each update, leaving very little duplicate content, but the old ones are still on the google index. Would it hurt the rankings to clean up these older versions & 301 redirect to the new versions, or should we leave them? The site for reference is: http://takeholdprinting.com

What Should I Do With My URL Names?
I release property on my blog each week, and it has come to the point we will get property in the same area as we have had in the past. So, I name my URL /blah-blah-blah-[area of property]/ for the first property in that area right. Now I get a different property in that same area and the URL will have to be named /blah-blah-blah-[area of property]-2/. Now I'm not sure if this is a major issue or not, but I'm sure there must be a better way than this, and I don't really want to take down our past properties - unless you can give me good reason too, of course? So before I start getting URLs like this: /blah-blah-blah-[area of property]-2334343534654/ (well, ok, maybe not that bad! But you get my point) I wanted to see what everyones opinion on it is 🙂 Thanks in advance!

Best solution to get mass URl's out the SE's index
Hi, I've got an issue where our web developers have made a mistake on our website by messing up some URL's . Because our site works dynamically IE the URL's generated on a page are relevant to the current URL it ment the problem URL linked out to more problem URL's - effectively replicating an entire website directory under problem URL's - this has caused tens of thousands of URL's in SE's indexes which shouldn't be there. So say for example the problem URL's are like www.mysite.com/incorrect-directory/folder1/page1/ It seems I can correct this by doing the following: 1/. Use Robots.txt to disallow access to /incorrect-directory/* 2/. 301 the urls like this:
Intermediate & Advanced SEO | | James77
www.mysite.com/incorrect-directory/folder1/page1/
301 to:
www.mysite.com/correct-directory/folder1/page1/ 3/. 301 URL's to the root correct directory like this:
www.mysite.com/incorrect-directory/folder1/page1/
www.mysite.com/incorrect-directory/folder1/page2/
www.mysite.com/incorrect-directory/folder2/ 301 to:
www.mysite.com/correct-directory/ Which method do you think is the best solution? - I doubt there is any link juice benifit from 301'ing URL's as there shouldn't be any external links pointing to the wrong URL's.0
