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?

Link juice through URL parameters
Hi guys, hope you had a fantastic bank holiday weekend. Quick question re URL parameters, I understand that links which pass through an affiliate URL parameter aren't taken into consideration when passing link juice through one site to another. However, when a link contains a tracking URL parameter (let's say gclid=), does link juice get passed through? We have a number of external links pointing to our main site, however, they are linking directly to a unique tracking parameter. I'm just curious to know about this. Thanks, Brett

If Robots.txt have blocked an Image (Image URL) but the other page which can be indexed has this image, how is the image treated?
Hi MOZers, This probably is a dumb question but I have a case where the robots.tags has an image url blocked but this image is used on a page (lets call it Page A) which can be indexed. If the image on Page A has an Alt tags, then how is this information digested by crawlers? A) would Google totally ignore the image and the ALT tags information? OR B) Google would consider the ALT tags information? I am asking this because all the images on the website are blocked by robots.txt at the moment but I would really like website crawlers to crawl the alt tags information. Chances are that I will ask the webmaster to allow indexing of images too but I would like to understand what's happening currently. Looking forward to all your responses 🙂 Malika

Duplicate URLs ending with #!
Hi guys, Does anyone know why a site can contain duplicate URLs ending with hastag & exclamation mark e.g. https://site.com.au/#! We are finding a lot of these URLs (as duplicates) and i was wondering what they are from developer standpoint? And do you think it's worth the time and effort adding a rel canonical tag or 301 to these URLs eventhough they're not getting indexed by Google? Cheers, Chris

How to de-index old URLs after redesigning the website?
Thank you for reading. After redesigning my website (5 months ago) in my crawl reports (Moz, Search Console) I still get tons of 404 pages which all seems to be the URLs from my previous website (same root domain). It would be nonsense to 301 redirect them as there are to many URLs. (or would it be nonsense?) What is the best way to deal with this issue?

Replace dynamic paramenter URLs with static Landing Page URL - faceted navigation
Hi there, got a quick question regarding faceted navigation. If a specific filter (facet) seems to be quite popular for visitors. Does it make sense to replace a dynamic URL e.x http://www.domain.com/pants.html?a_type=239 by a static, more SEO friendly URL e.x http://www.domain.com/pants/levis-pants.html by creating a proper landing page for it. I know, that it is nearly impossible to replace all variations of this parameter URLs by static ones but does it generally make sense to do this for the most popular facets choose by visitors. Or does this cause any issues? Any help is much appreciated. Thanks a lot in advance

Attack of the dummy urls -- what to do?
It occurs to me that a malicious program could set up thousands of links to dummy pages on a website: www.mysite.com/dynamicpage/dummy123 www.mysite.com/dynamicpage/dummy456 etc.. How is this normally handled? Does a developer have to look at all the parameters to see if they are valid and if not, automatically create a 301 redirect or 404 not found? This requires a table lookup of acceptable url parameters for all new visitors. I was thinking that bad url names would be rare so it would be ok to just stop the program with a message, until I realized someone could intentionally set up links to non existent pages on a site.

http://www.eee.mysite.com
http://www.w.mysite.com The site these links are coming from is a html site. Any ideas whats going on or a way to get rid of these urls? When I visit the strange URLs such as http://www.dwww.mysite.com, it shows the home page of http://www.mysite.com. Is there a way to redirect anything like this back to the home page?0 -
Adding index.php at the end of the url effect it's rankings
I have just had my site updated and we have put index.php at the end of all the urls. Not long after the sites rankings dropped. Checking the backlinks, they all go to (example) http://www.website.com and not http://www.website.com/index.php. So could this change have effected rankings even though it redirects to the new url?
