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?

How to stop URLs that include query strings from being indexed by Google
Hello Mozzers Would you use rel=canonical, robots.txt, or Google Webmaster Tools to stop the search engines indexing URLs that include query strings/parameters. Or perhaps a combination? I guess it would be a good idea to stop the search engines crawling these URLs because the content they display will tend to be duplicate content and of low value to users. I would be tempted to use a combination of canonicalization and robots.txt for every page I do not want crawled or indexed, yet perhaps Google Webmaster Tools is the best way to go / just as effective??? And I suppose some use meta robots tags too. Does Google take a position on being blocked from web pages. Thanks in advance, Luke

How can I make a list of all URLs indexed by Google?
I started working for this eCommerce site 2 months ago, and my SEO site audit revealed a massive spider trap. The site should have been 3500-ish pages, but Google has over 30K pages in its index. I'm trying to find a effective way of making a list of all URLs indexed by Google. Anyone? (I basically want to build a sitemap with all the indexed spider trap URLs, then set up 301 on those, then ping Google with the "defective" sitemap so they can see what the site really looks like and remove those URLs, shrinking the site back to around 3500 pages)

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?

Are these URL hashtags an SEO issue?
Hi guys - I'm looking at a website which uses hashtags to reveal the relevant content So there's page intro text which stays the same... then you can click a button and the text below that changes So this is www.blablabla.com/packages is the main page - and www.blablabla.com/packages#firstpackage reveals first package text on this page - www.blablabla.com/packages#secondpackage reveals second package text on this same page - and so on. What's the best way to deal with this? My understanding is the URLs after # will not be indexed very easily/atall by Google - what is best practice in this situation?

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?

URL Structure for Directory Site
We have a directory that we're building and we're not sure if we should try to make each page an extension of the root domain or utilize sub-directories as users narrow down their selection. What is the best practice here for maximizing your SERP authority? Choice #1 - Hyphenated Architecture (no sub-folders): State Page /state/ City Page /city-state/ Business Page /business-city-state/
Intermediate & Advanced SEO | | knowyourbank
4) Location Page /locationname-city-state/ or.... Choice #2 - Using sub-folders on drill down: State Page /state/ City Page /state/city Business Page /state/city/business/
4) Location Page /locationname-city-state/ Again, just to clarify, I need help in determining what the best methodology is for achieving the greatest SEO benefits. Just by looking it would seem that choice #1 would work better because the URL's are very clear and SEF. But, at the same time it may be less intuitive for search. I'm not sure. What do you think?0
