How long will Google take to stop crawling an old URL once it has been 301 redirected
-
I need to do a clean-up old urls that have been redirected in sitemap and was wondering about this.
-
I agree with Ryan. As long as the old URLs are out there in the web, Google will follow them.
At the same time, redirected URL list will be very lengthy if you are maintaining a big site and maintaining them will consume your resources.
Check link value of the old URLs as a first step. If they have no value then you will be fine to retire such old URLs.
-
Google's crawler will always attempt to crawl any links it finds. If somewhere on the internet there is a link to an old URL and Google sees that link, it will never stop trying to explore that link. Each time it attempts to crawl the link, it will see the 301 and follow the redirect, but if you ever remove that redirect then the original URL will be seen.

Google is indexing bad URLS
Hi All, The site I am working on is built on Wordpress. The plugin Revolution Slider was downloaded. While no longer utilized, it still remained on the site for some time. This plugin began creating hundreds of URLs containing nothing but code on the page. I noticed these URLs were being indexed by Google. The URLs follow the structure: www.mysite.com/wp-content/uploads/revslider/templates/this-part-changes/ I have done the following to prevent these URLs from being created & indexed: 1. Added a directive in my Htaccess to 404 all of these URLs 2. Blocked /wp-content/uploads/revslider/ in my robots.txt 3. Manually de-inedex each URL using the GSC tool 4. Deleted the plugin However, new URLs still appear in Google's index, despite being blocked by robots.txt and resolving to a 404. Can anyone suggest any next steps? I Thanks!

1000 Pages on old website. What to do with the 301 redirects for this domain?
Hi Moz Community, I have a 301 redirect question... I just acquired an old domain: Totally in my niche Domain is 14 years old Website exists of 1000 pages Great amount of backlinks Website is offline since about 2 weeks Will place a new website online asap with new url structure For the 50 best scoring pages I wrote a new, but fully comparable/related article. I will put a 301 redirect from those old to the new pages. My question: What to do with the 950 other url's? Should I put a 301 redirect to the homepage? Should I forward those pages to the 404 page? Should I divide the 950 url's with a 301 redirect to the 50 new ones? Another solution maybe? Any idea what would be the best solution so we can save as much Google juice as possible? Thanks in advance!

301 redirect: canonical or non canonical?
Hi, Newbie alert! I need to set up 301 redirects for changed URLs on a database driven site that is to be redeveloped shortly. The current site uses canonical header tags. The new site will also use canonical tags. Should the 301 redirects map the canonical URL on the old site to the corresponding canonical for the new design . . . or should they map the non canonical database URLs old and new? Given that the purpose of canonicals is to indicate our preferred URL, then my guess is that's what I should use. However, how can I be sure that Google (for example) has indexed the canonical in every case? Thx in anticipation.

Mobile URL parameter (Redirection to desktop)
Hello, We have a parallel mobile website and recently we implemented a link pointing to the desktop website. This redirect is happening via a javascript code and results in a url followed by this paramenter: ?m=off Example:
Technical SEO | | echo1
http://www.m.website.com redirects to:
http://www.website.com/?m=off Questions: Will the "http://www.website.com/?m=off" be considered duplicate content with "http://www.website.com" since they both return the same content? Is there any possibility that Google will take into consideration the url ending in "/?m=off"? How should we treat this new url? The webmaster tools URL parameter configuration at the moment isn't experiencing problems but should we submit the parameter anyway in order not to be indexed or should we wait first and see the error response? In case we should submit this for removal... what's the best way to do it? Like this? Parameter: ?m=off Does this parameter change page content seen by the user? - doesn't affect page content Any help is much appreciated.
Thank you!0 -
CDN Being Crawled and Indexed by Google
I'm doing a SEO site audit, and I've discovered that the site uses a Content Delivery Network (CDN) that's being crawled and indexed by Google. There are two sub-domains from the CDN that are being crawled and indexed. A small number of organic search visitors have come through these two sub domains. So the CDN based content is out-ranking the root domain, in a small number of cases. It's a huge duplicate content issue (tens of thousands of URLs being crawled) - what's the best way to prevent the crawling and indexing of a CDN like this? Exclude via robots.txt? Additionally, the use of relative canonical tags (instead of absolute) appear to be contributing to this problem as well. As I understand it, these canonical tags are telling the SEs that each sub domain is the "home" of the content/URL. Thanks! Scott

Can you 301 redirect a page to an already existing/old page ?
If you delete a page (say a sub department/category page on an ecommerce store) should you 301 redirect its url to the nearest equivalent page still on the site or just delete and forget about it ? Generally should you try and 301 redirect any old pages your deleting if you can find suitable page with similar content to redirect to. Wont G consider it weird if you say a page has moved permenantly to such and such an address if that page/address existed before ? I presume its fine since say in the scenario of consolidating departments on your store you want to redirect the department page your going to delete to the existing pages/department you are consolidating old departments products into ?
