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?

Google does not want to index my page
I have a site that is hundreds of page indexed on Google. But there is a page that I put in the footer section that Google seems does not like and are not indexing that page. I've tried submitting it to their index through google webmaster and it will appear on Google index but then after a few days it's gone again. Before that page had canonical meta to another page, but it is removed now.

1 duplicate I have recently transfered my old html site to wordpress.
To keep the urls the same I am using a plugin which appends .htm at the end of each page. My old site home page was index.htm. I have created index.htm in wordpress as well but now there is a conflict of duplicate content. I am using latest post as my home page which is index.php Question 1.
Should I also use redirect 301 im htaccess file to transfer index.htm page authority (19) to www.example.com If yes, do I use
Redirect 301 /index.htm http://www.example.com/index.php
or
Redirect 301 /index.htm http://www.example.com Question 2
Should I change my "Home" menu link to http://www.example.com instead of http://www.example.com/index.htm that would fix the duplicate content, as indx.htm does not exist anymore. Is there a better option? Thanks0 -
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)

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

URL mapping for site migration
Hi all! I'm currently working on a migration for a large e-commerce site. The old one has around 2.5k urls, the new one 7.5k. I now need to sort out the redirects from one to the other. This is proving pretty tricky, as the URL structure has changed site wide. There doesn't seem to be any consistent rules either so using regex doesn't really work. By and large, the copy appears to be the same though. Does anybody know of a tool I can crawl the sites with that will export the crawled url and related copy into a spreadsheet? That way I can crawl both sites and compare the copy to match them up. Thanks!

Google News URL Structure
Hi there folks I am looking for some guidance on Google News URLs. We are restructuring the site. A main traffic driver will be the traffic we get from Google News. Most large publishers use: www.site.com/news/12345/this-is-the-title/ Others use www.example.com/news/celebrity/12345/this-is-the-title/ etc. www.example.com/news/celebrity-news/12345/this-is-the-title/ www.example.com/celebrity-news/12345/this-is-the-title/ (Celebrity is a channel on Google News so should we try and follow that format?) www.example.com/news/celebrity-news/this-is-the-title/12345/ www.example.com/news/celebrity-news/this-is-the-title-12345/ (unique ID no at the end and part of the title URL) www.example.com/news/celebrity-news/celebrity-name/this-is-the-title-12345/ Others include the date. So as you can see there are so many combinations and there doesnt seem to be any unity across news sites for this format. Have you any advice on how to structure these URLs? Particularly if we want to been seen as an authority on the following topics: fashion, hair, beauty, and celebrity news - in particular "celebrity name" So should the celebrity news section be www.example.com/news/celebrity-news/celebrity-name/this-is-the-title-12345/ or what? This is for a completely new site build. Thanks Barry
