How long after google crawl do you need 301 redirects
-
We have just added 301's when we moved our site. Google has done a crawl & spat back a few errors. How long do I need to keep those 301's in place? I may need to change some. Thanks

Google will continue to crawl your old URLs as long as links to them exist, so you will want to keep those 301s in place for as long as those links exist. Does that make sense?
It's not that Google will crawl a URL, see that it is being 301'd and never crawl that URL, Google will continuously crawl that URL as long as it is being linked to, and you need to have the 301 in place to tell Google that the page has moved.

Thanks for the quick response. Basically, we changed from a hosted solution to magento & needed to redirect all of our old url's to the magento URL structure. I guess what I need to know is, once google has crawled & found the 301, does it then ignore the 301 in future (as it already knows it has been moved)?

You need to keep those 301s in place as long as you have links pointing to the old site that you want to get credit for. If you can contact the owners of the sites that are linking to your old site and get them to change the links, you can remove the 301s. Otherwise you will want to keep them in place.

Google's ability to crawl AJAX rendered content
I would like to make a change to the way our main navigation is currently rendered on our e-commerce site. Currently, all of the content that appears when you click a navigation category is rendering on page load. This is currently a large portion of every page visit’s bandwidth and even the images are downloaded even if a user doesn’t choose to use the navigation. I’d like to change it so the content appears and is downloaded only IF the user clicks on it, I'm planning on using AJAX. As that is the case it wouldn’t not be automatically on the site(which may or may not mean Google would crawl it). As we already provide a sitemap.xml for Google I want to make sure this change would not adversely affect our SEO. As of October this year the Webmaster AJAX crawling doc. suggestions has been depreciated. While the new version does say that its crawlers are smart enough to render AJAX content, something I've tested, I'm not sure if that only applies to content injected on page load as opposed to in click like I'm planning to do.

301 Redirect Timing Questions
Hey all, Quick question on 301 redirects and the timing of creating them when transitioning from an old site to a new site. Does the timing matter? Can redirects interfere with DNS propigation (which seemed to happen to us when we did redirects minutes after redirecting someone's DNS A record to now point to the new site) And lastly, how long AFTER a new site launch can one still submit redirects and not lose the google juice? All the best,

.EDU via a 301 Redirect?
I recently received a link to my website from an .edu. However, the way they configured it was they pointed the link to one of their internal pages and then made that page 301 to my website. Is there anyway to gain any link juice from that sort of link?

Where does Wordpress store the 301 redirects?
Hi, I've just created a campaign for my new wordpress blog and found 11 301 redirects which I was not aware of. It looks like wordpress has created them automatically. Does any one know how wordpress handles this issues or where are they stored so I can delete them? They are of no use for me. 9 of these redirects point to the same url with an added '/' and are in pages 1 is on a post. I've been changing the permalink and some urls several times and maybe one of these times the Wordpress has automatically created the 301 redirect. But why? I do not want to keep the old url. the last redirect is very strange it goes from http://www.mydomain.com/folder to http://www.mydomain.com where folder is the folder where I installed wordpress. But again, I want no one to type the url with the folder name or even know this folder exists. Any comment on this would be greatly appreciated. Thanks a lot, David

Magento - Google Webmaster Crawl Errors
Hi guys, Started my free trial - very impressed - just thought I'd ask a question or two while I can. I've set up the website for http://www.worldofbooks.com (large bookseller in the UK), using Magento. I'm getting a huge amount of not found crawl errors (27,808), I think this is due to URL rewrites, all the errors are in this format (non search friendly): http://www.worldofbooks.com/search_inventory.php?search_text=&category=&tag=Ure&gift_code=&dd_sort_by=price_desc&dd_records_per_page=40&dd_page_number=1 As oppose to this format: http://www.worldofbooks.com/arts-books/history-of-art-design-styles/the-art-book-by-phaidon.html (the re-written URL). This doesn't seem to really be affecting our rankings, we targeted 'cheap books' and 'bargain books' heavily - we're up to 2nd for Cheap Books and 3rd for Bargain Books. So my question is - are these large amount of Crawl errors cause for concern or is it something that will work itself out? And secondly - if it is cause for concern will it be affecting our rankings negatively in any way and what could we do to resolve this issue? Any points in the right direction much appreciated. If you need any more clarification regarding any points I've raised just let me know. Benjamin Edwards

301 Redirects
Last year we merged 3 websites into 1 website and launched the new site in February. When developing the new site I created 301 redirects for all the pages from the old sites to the new site. Unfortunately when the new website was created the URLs were not optimised for search engines. I now need to optimised the page URLs. In theory I need to create new 301 redirects from this existing pages to the new optimised URLS. I am concerned that in a few years I might end up with a string of 301 redirects and if I break some links I might loose some ranking. How many redirects will link juice work for? I hope I'm clear here, if not I've attached a image showing what I'm doing. Thank you. unledfh.jpg
