Changing .html to .asp in URLs
-
Hi Mozzers,
I have a question. The webmaster of a client of mine needs to make changes to some files which will effect the URL's.
Essentially everything is staying the same but the end of the URL will change from .html to .asp.
This is because the site will be dynamically loading content (perhaps from a database) (i.e. latest news to come from their blog etc..) In order to do this we would need to change the filenames of the whole website. (i.e. personnel.html would become personel.asp).
Changing URLs can harm indexation but a small change to the end - would Google drop these pages? A 301 redirect is not possible from old URL to new.
What impact would this have on Rankings?
Thanks
Gareth

Hi Kevin, O French and Dr Pete,
Thanks for your input - I'm being told a 301 isn't possible but looking at your comments we can do it and I'll push for it.
Thanks so much for all of your help

Yeah, I'm with Kevin - there's a way to do a 301-redirect, and you need to find it. Otherwise, you'll lose the value of most of the current links to your site, and you'll create a ton of 404s from visitors and links with old URLs trying to find the old content. That's an SEO nightmare waiting to happen, and it's bad for usability, too.

Similar to Kevin's response, I have a section in my web.config performing a similar action, should be something like this I believe -
<match url="^([a-z]*).htm"></match>
<action type="Redirect" url="{R:1}.asp"></action>
This should just redirect any instance of .htm to .asp.

Why isn't a 301 possible? If the host doesn't have ISAPI_Rewrite, then a custom 404 that contains a 301 will work.
There would be a big impact on rankings otherwise.

Desktop Ranking Disappeared After URL Change; Mobile Ranking Improved
A client's developer moved a site onto a new (WordPress) CMS, where the only change was URLs - the front end code stayed the same. The site is 10+ years old and previously had fantastic rankings (#1-4) with inner pages for some relatively generic search phrases (eg 10,000 searches / month in the UK, per Keyword Planner). Now, on Desktop searches the site isn't appearing anywhere in the 300+ results for a key search phrase, where it used to rank between #2-4; however over the last 3 weeks on Mobile the site ranks better than before, even though the site isn't at all mobile-friendly (it's over 10 years old). During the move, there were some errors by their developer: mistakenly left in a sitewide rel=canonical tag referring to the homepage 3-4 301s before finally reaching new URLs a lot of 301s missed (250+ crawl errors appeared in Search Console) page content differentiation by parameter, instead of individual URLs For example, the page that used to rank for the targeted phrase, this left 4 different URLs indexed, with the same content. To tackle this, we have so far: put in correct rel=canonical tags set up Search Console to recognise URL parameter as differentiating content fixed all crawl errors appearing in Search Console added a link direct to the problem page, direct from the homepage stopped duplicate content being indexed (including for the page in question) ensured the page load speed is still good (< 0.75s) Ranking for Desktop over Mobile would make sense, but not Mobile over Desktop! I'd really appreciate any advice on how to tackle this. Thanks!

URL Question: Is there any value for ecomm sites in having a reverse "breadcrumb" in the URL?
Wondering if there is any value for e-comm sites to feature a reverse breadcrumb like structure in the URL? For example: Example: https://www.grainger.com/category/anchor-bolts/anchors/fasteners/ecatalog/N-8j5?ssf=3&ssf=3 where we have a reverse categorization happening? with /level2-sub-cat/level1-sub-cat/category in the reverse order as to the actual location on the site. Category: Fasteners

OSE says URL redirects to URL with trailing slash but it doesn't.
Site is www.example.com/folder/us and OSE says this URL redirects to www.example.com/folder/us/, but it does not. When I look at the OSE report for the latter version with the "/" it says "No Data Available For This URL". Why would that be? The original URL is www.example.com and it redirects to www.example.com/folder/us. Is this anything I need to worry about? I thought that the trailing / doesn't really mean much anymore but nonetheless, why does it think it redirects there?

Change in url structure - added category page
I have recently started an e-commerce website and have now changed the url structure and added another level to my category pages. So where it before was www.website.com/shirts it is now www.website.com/clothes/shirts. So I added the clothes category (just an example) before the shirt category and am now finding that the old url is still found in the search index and is still live on my site. How could this be? I use wordpress and simply change the urls in the backend. The products are still under www.website.com/product/blue-shirt-123 so they won't be affected but I suppose it now means I have duplicate category pages? So my question is: Should I 301 the the old category page (www.website.com/shirts)to the new url (www.website.com/clothes/shirts). And how can the old url still be live on my site? If this was a bit unclear, please let me know. Appreciate your replies!

GWT, URL Parameters, and Magento
I'm getting into the URL parameters in Google Webmaster Tools and I was just wondering if anyone that uses Magento has used this functionality to make sure filter pages aren't being indexed. Basically, I know what the different parameters (manufacturer, price, etc.) are doing to the content - narrowing. I was just wondering what you choose after you tell Google what the parameter's function is. For narrowing, it gives the following options: Which URLs with this parameter should Googlebot crawl? <label for="cup-crawl-LET_GOOGLEBOT_DECIDE">Let Googlebot decide</label> (Default) <label for="cup-crawl-EVERY_URL">Every URL</label> (the page content changes for each value) <label style="color: #5e5e5e;" for="cup-crawl-ONLY_URLS_WITH_VALUE">Only URLs with value</label> ▼(may hide content from Googlebot) <label for="cup-crawl-NO_URLS">No URLs</label> I'm not sure which one I want. Something tells me probably "No URLs", as this content isn't something a user will see unless they filter the results (and, therefore, should not come through on a search to this page). However, the page content does change for each value.I want to make sure I don't exclude the wrong thing and end up with a bunch of pages disappearing from Google.Any help with this is greatly appreciated!

Canonical URL Issue
Hi Everyone, I'm fairly new here and I've been browsing around for a good answer for an issue that is driving me nuts here. I tried to put the canonical url for my website and on the first 5 or 6 pages I added the following script SEOMoz reported that there was a problem with it. I spoke to another friend and he said that it looks like it's right and there is nothing wrong but still I get the same error. For the URL http://www.cacaniqueis.com.br/video-caca-niqueis.html I used the following: <link rel="<a class="attribute-value">canonical</a>" href="http://www.cacaniqueis.com.br/video-caca-niqueis.html" /> Is there anything wrong with it? Many thanks in advance for the attention to my question.. 🙂 Alex

URL rewriting from subcategory to category
Hello everybody! I have quite simple question about URL rewriting from subcategory to category, yet I can't find any solution to this problem (due to lack of my deeper apache programming knowledge). Here is my problem/question: we have two website url structures that causes dublicate problems: www.website.lt/language/category/ www.website.lt/language/category/1/ 1 and 2 pages are absolutely same (both also returns 200 OK). What we need is 301 redirect from 2 to 1 without any other deeper categories redirects (like www.website.com/language/category/1/169/ redirecting to .../category/1/ or .../category/). Here goes .htaccess URL rewrite rules: RewriteRule ^([^/]{1,3})/([^/]+)/([^/]+)/([^/]+)/([^/]+)/([^/]+)/$ /index.php?lang=$1&idr=$2&par1=$3&par2=$4&par3=$5&par4=$6&%{QUERY_STRING} [L] RewriteRule ^([^/]{1,3})/([^/]+)/([^/]+)/([^/]+)/([^/]+)/$ /index.php?lang=$1&idr=$2&par1=$3&par2=$4&par3=$5&%{QUERY_STRING} [L] RewriteRule ^([^/]{1,3})/([^/]+)/([^/]+)/([^/]+)/$ /index.php?lang=$1&idr=$2&par1=$3&par2=$4&%{QUERY_STRING} [L] RewriteRule ^([^/]{1,3})/([^/]+)/([^/]+)/$ /index.php?lang=$1&idr=$2&par1=$3&%{QUERY_STRING} [L] RewriteRule ^([^/]{1,3})/([^/]+)/$ /index.php?lang=$1&idr=$2&%{QUERY_STRING} [L] RewriteRule ^([^/]{1,3})/$ /index.php?lang=$1&%{QUERY_STRING} [L] There are other redirects that handles non-www to www and related issues: RedirectMatch 301 ^/lt/$ http://www.domain.lt/ RewriteCond %{HTTP_HOST} ^domain.lt RewriteRule (.*) http://www.domain.lt/$1 [R=301,L] RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_URI} !(.)/$RewriteRule ^(.)$ http://www.domain.lt/$1/ [R=301,L] At this moment we cannot solve this problem with rel canonical (due to our CMS limits). Thanks for your help guys! If You need any other details on our coding, just let me know.

Hyphen in URL
Hi, I would like to know if the following statement holds true today or it doesn't matter whether we use hyphens or underscore If you have a URL like keyword1_keyword2, Google will only return that page if the user searches for keyword1_keyword2 ( highly unlikely ) . But If you have a URL like keyword1-keyword2, that page can be returned for the searches - keyword1,keyword2 and even “keyword1keyword2” Thanks
