When to use mod rewrite / canonical / 301 redirect
-
Hello,
I have taken over the management of a site which has a big problem with duplicate content. The duplicate content is caused by two things:
- Upper and lower case urls e.g: www.mysite.com/blog and www.mysite.com/Blog
- The other reason is the use of product filters / pagination which mean you can get to the same 'page' via different filters. The filters generate separate URLs.
http://www.mysite.com/casestudy
http://www.mysite.com/casestudy/filter?page=1
http://www.mysite.com/casestudy/filter?solution=0&page=1
http://www.mysite.com/casestudy?page=1
http://www.cpio.co.uk/casestudy/filter?solution=0"Am I right to assume that for the case sensitive URLs I should use a 301 redirect because I only want the lower page to be shown?
For the issue with dynamic URLs should we implement a mod-rewrite and 301 to one page?
Any advice would be greatly appreciated.

Hi
I would definitely setup a 301 redirect for the case sensitive URLs issue - you may already know how to setup this up but I thought I would include this link - http://webmasters.stackexchange.com/questions/18670/how-to-redirect-any-url-to-lowercase-url
For your pagination issue you need to look at if it is possible to change /casestudy to a "view all" page and then place a canonical link to the /casestudy page in the of each page in the paginated set.
Another option for your pagination is using rel="next" and rel="prev" and for the filter parameters you could tell Googlebot not to crawl these parameter URLs.
Hope this helps

Which Version Url to Use for Canonical Tags and in General for Homepage.
I want to put canonical tags on the homepage of a site. cant figure out the version of URL of the homepage should be with a / at the end or without the / ( www.example.com of www.example.com/ ) if I put into the google the URL with / I get the URL without the / in my browser, and it isn't showing as a redirect in my moz extension or other tools. But when I copy the URL from browser and paste elsewhere it pastes with a / I have two questions 1 - in general how does it work with URLs of homepages - I see this happening with lots of sites? 2 - which URL should I set as the canonical version of my homepage? Thanks so much

301 redirect and search engines
How long until 301 redirects get recognized by search engines? I noticed my link on Google isn't forwarding over to my new domain even after the 301 redirect. If I go to the site directly, the 301 redirect works. Anyone know how long it takes for search engines to pick it up? Thanks!

How to redirect my .com/blog to my server folder /blog ?
Hello SEO Moz ! Always hard to post something serious for the 04.01 but anyway let's try ! I'm releasing Joomla websites website.com, website.com/fr, website.com/es and so on. Usually i have the following folders on my server [ROOT]/com [ROOT]/com/fr [ROOT]/com/es However I would like to get the following now (for back up and security purpose). [ROOT]/com [ROOT]/es [ROOT]/fr So now what can I do (I gues .htaccess) to open the folder [ROOT]/es when people clic on website.com/es ? It sounds stupid but I really don't know. I found this on internet but did not answer my needs. .htaccess RewriteEngine On

302 to 301 redirect
Our site has quite a few 302 redirects that really ought to be 301's. Our IT department is really busy so the question is, given that the 302's have probably been in place for years, is it worth changing them to 301's now? Thanks

Job/Blog Pages and rel=canonical
Hi, I know there are several questions and articles concerning the rel=canonical on SEOmoz, but I didn't find the answer I was looking for... We have some job pages, URLs are: /jobs and then jobs/2, jobs/3 etc.. Our blog pages follow the same: /blog, /blog2, /blog/3... Our CMS is self-produced, and every job/blog-page has the same title tag. According to SEOmoz (and the Webmaster Tools), we have a lots of duplicate title tags because of this problem. If we put the rel=canonical on each page's source code, the title tag problem will be solved for google, right? Because they will just display the /job and /blog main page. That would be great because we dont want 40 blog pages in the index. My concern (a stupid question, but I am not sure): if we put the rel=canonical on the pages, does google crawl them and index our job links? We want to keep our rankings for our job offers on pages 2-xxx. More simple: will we find our job offers on jobs/2, jobs/3... in google, if these pages have the rel=canonical on them? AND ONE MORE: does the SEOmoz bot also follow the rel=canonical and then reduce the number of duplicate title-tags in the campaigns??? Thanx........

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
