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.

Removing Multiple 301 Redirects
During my last redesign (and migration to Drupal) some of the updated SEO friendly url's on the new site were misspelled. Rather than updating the 301 redirects to point to the correct page the developer just added an additional 301 redirect. So it was redirected like this website.com/oldpage (301 to) website.com/new-paige (301 to) website.com/new-page Instead of website.com/oldpage (301 to) website.com/new-page I'll be finishing another redesign and updating to https soon, should I remove the redirect to the misspelled domain and just have one 301 from the original page? These multiple redirects have been up for over a year. Thanks for any specific advice!

Max Number of 301 Redirections?
Hi, We currently made a re-design of a website and we changed all our urls to make them shorter. I made more than 300 permanent redirections but plenty more are needed since WMT is showing some more 404s from old urls that I hadn't seen because they were dynamic. The question is, please, is there a limit? I think we have more than 600 already. We don't want to create a php commando to redirect all the old ones to our home, we are redirecting them to their correspondent url. By the way, Im doing them with the 301 method in .htaccess. Thanks in advance.

.htaccess Redirect 301 issues
I have completely rewritten my web site, adding structure to the file directories. Subsequently added was Redirect information within the .htaccess file. The following example ...

Returns this response in the URL bar of ...

I am at a loss to understand why the suffix "?file=armaflex" is added The following code is inserted at the top of the file ...
RewriteEngine On redirect html pages to the root domain RewriteRule ^index.html$ / [NC,R,L] Force www. prefix in URLs and redirect non-www to www RewriteCond %{http_host} ^just-insulation.com [NC]
RewriteRule ^(.*)$ http://www.just-insulation.com/ [R=301,NC] Any advice would be most welcome.0 -
I have an eCommerce store with a lot of 301 redirects. Would that hurt my rankings?
I use BigCommerce, and they have a system where all the URLs are dynamically generated from the name of each product. So if I named a product "widget x y z" the url would be /widget-x-y-z/, and if I changed that to "blue widget x y z", it would change to /blue-widget-x-y-z/ and automatically redirect the old one to the new one. As a result, in 6 months, because of a lot of tweaking and experimenting, I've ended up with a hefty list of 400 redirects. Some of them are very old, and some are recent. So my question is in two parts: a) does having all of these redirects hurt my rankings? b) if so, would deleting them help?

301 redirecting some pages directly, and the rest to a single page
I've read through the Redirect guide here already but can't get this down in my .htaccess I want to redirect some pages specifically (/contactinfo.html to the new /contact.php) And I want all other pages (not all have equivalent pages on the new site) to redirect to my new (index.php) homepage. How can I set it up so that some specific pages redirect directly, and all others go to one page? I already have the specific oldpage.html -> newpage.php redirects in place, just need to figure out the broad one for everything else.

Will Google index a 301 redirect for a new site?
So here is the problem... We have setup a 301redirect for our clients website. When you search the clients name it comes up with the old .co.uk website. We have made this redirect to the new .com website. However on the SERPs when it shows the .co.uk it shows the old title pages which currently say 'Holding Page'. When you click on that link it takes you to the fully functioning .com website. My question is, will the title tags in the SERPs which show the .co.uk update to the new ones from the .com? I'm thinking it will be just a case of Google catching up on things and it will sort itself out eventually. If anyone could help I would REALLY appreciate it. Thanks Chris

Google crawl index issue with our website...
Hey there. We've run into a mystifying issue with Google's crawl index of one of our sites. When we do a "site:www.burlingtonmortgage.biz" search in Google, we're seeing lots of 404 Errors on pages that don't exist on our site or seemingly on the remote server. In the search results, Google is showing nonsensical folders off the root domain and then the actual page is within that non-existent folder. An example: Google shows this in its index of the site (as a 404 Error page): www.burlingtonmortgage.biz/MQnjO/idaho-mortgage-rates.asp The actual page on the site is: www.burlingtonmortgage.biz/idaho-mortgage-rates.asp Google is showing the folder MQnjO that doesn't exist anywhere on the remote. Other pages they are showing have different folder names that are just as wacky. We called our hosting company who said the problem isn't coming from them... Has anyone had something like this happen to them? Thanks so much for your insight!
