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.

Reusing an already 301 redirected URL for a very important keyword
I have a question about reusing an already 301 redirected URL Till now I never reused an URLs that has been already redirected with a 301 redirect. However, I just started working on a website where in past they created a lot of 301 redirects without thinking about the future, and now certain URLs, that are currently redirected with a 301, would be very useful (exact match) and needed (for some of the most important keywords for this specific business), to maintain an optimal, homogeneous and "beautiful" URL structure. Has any of you ever reused a URL that was previously redirected with a 301 redirect? If yes what are your experiences with it? Can content on the reused URL (that was previously 301 redirected and than the redirect removed) normally rank if the page is reestablished and the redirect is removed (and you do great content, on page, internal linking, backlinking, .... ) or is such an URL risky / not recommended / "burned" forever and not recommended to be reused again... especially for very important keywords since it present the exact match ?! Thank you very much for all your help! Regards

How google crawls images and which url shows as source?
Hi, I noticed that some websites host their images to a different url than the one their actually website is hosted but in the end google link to the one that the site is hosted. Here is an example: This is a page of a hotel in booking.com: http://www.booking.com/hotel/us/harrah-s-caesars-palace.en-gb.html When I try a search for this hotel in google images it shows up one of the images of the slideshow. When I click on the image on Google search, if I choose the Visit Page button it links to the url above but the actual image is located in a totally different url: http://r-ec.bstatic.com/images/hotel/840x460/135/13526198.jpg My question is can you host your images to one site but show it to another site and in the end google will lead to the second one?

Google stopped crawling my site. Everybody is stumped.
This has stumped the Wordpress staff and people in the Google Webmasters forum. We are in Google News (have been for years), and so new posts are crawled immediately. On Feb 17-18 Crawl Stats dropped 85%, and new posts were no longer indexed (not appearing on News or search). Data highlighter attempts return "This URL could not be found in Google's index." No manual actions by Google. No changes to the website; no custom CSS. No Site Errors or new URL errors. No sitemap problems (resubmitting didn't help). We're on wordpress.com, so no odd code. We can see the robot.txt file. Other search engines can see us, as can social media websites. Older posts still index, but loss of News is a big hit. Also, I think overall Google referrals are dropping. We can Fetch the URL for a new post, and many hours later it appears on Google and News, and we can then use Data Highlighter. It's now 6 days and no recovery. Everybody is stumped. Any ideas? I just joined, so this might be the wrong venue. If so, apologies.

Increase 404 errors or 301 redirects?
Hi all, I'm working on an e-commerce site that sells products that may only be available for a certain period of time. Eg. A product may only be selling for 1 year and then be permanently out of stock. When a product goes out of stock, the page is removed from the site regardless of any links it may have gotten over time. I am trying to figure out the best way to handle these permanently out of stock pages. At the moment, the site is set up to return a 404 page for each of these products. There are currently 600 (and increasing) instances of this appearing on Google Webmasters. I have read that too many 404 errors may have a negative impact on your site, and so thought I might 301 redirect these URLs to a more appropriate page. However I've also read that too many 301 redirects may have a negative impact on your site. I foresee this to be an issue several years down the road when the site has thousands of expired products which will result in thousands of 404 errors or 301 redirects depending on which route I take. Which would be the better route? Is there a better solution?

How to Stop Google from Indexing Old Pages
We moved from a .php site to a java site on April 10th. It's almost 2 months later and Google continues to crawl old pages that no longer exist (225,430 Not Found Errors to be exact). These pages no longer exist on the site and there are no internal or external links pointing to these pages. Google has crawled the site since the go live, but continues to try and crawl these pages. What are my next steps?

Vanity / Short URLs 301?
Hi everyone, I'm working on a website that uses a lot of short urls eg http://www.forest.com/oaktrees. A quick check reveals these are currently 302 status. My question is should these be made 301s - a lot of them are in off-page content and looking at GA attract a lot of clicks. I've not managed to see a definitive answer to this after several Google searches. All help and advice greatly appreciated. Bw Jon

How long should I keep 301 redirects?
I have modified a the URL structure of a whole section of a website and used mod_rewrite 301 redirect to match the new structure. Now that was around 3 months ago and I was wondering how long should I keep this redirect for? As it is a new website I am quite sure that there are no links around with the old URL structure but still I can see the google bot trying from time to time to access the old URL structure. Shouldn't the google bot learn from this 301 redirect and not go anymore for the old URL?
