      Saturday I waas doing some correcting of some duplicate titles, including nofollowing tags, etc. (my main problem was duplicate titles due to tags and categories being indexed).

      Now this morning I see that one of my pages refuses to load, citing a 301 redirect loop.

      http://www.incredibleinfant.com/feeding/switching-baby-formula/

      Originally, the page was posted under the wrong category.

      http://www.incredibleinfant.com/uncategorized/switching-baby-formula

      I resaved it under the correct category (feeding) and now it won't load.

      Can someone help me figure out how to correct this mess?

      Thanks so much

      Heather

          Hi Heather,

          Yes this is what I was looking for.

          Sorry for not getting back to you sooner.

          Generally the Wordpress core systems work great, its other modules that tend to cause issues. I don't see a specific problem with the htacess, did you install any other redirecting scripts like canonical redirects?

          It sounds like this maybe a somewhat common issue and you may find quicker answers to this sort of technical issue directly on the Wordpress forums. I've done some basic things with WP before, but I have not digested it to the degree you would expect to find on the official forums.

              Hi Heather, can you post your HTACCESS info that pertains to this redirect?

              You may simply have an ambiguous statement in there.

                How effective are 301 redirects in passing page rank?

                301 redirect page rank

                I have a blog which is ranking well for certain terms, and would like to repurpose it to better explain these terms it is ranking for, including updating the url to the new term the blog will be about. The plan being to 301 redirect the old url to new. In the past, I've done this with other pages, and have actually lost much of the rankings that I had earned on the original URL. What is your take on this? Maybe repurpose blog, but maintain original URL just to be on the safe side? Thanks

                How do you fix redirect chains and temporary redirects?

                Hi, I have a lot of issues popping up with temporary redirects and redirect chains. I'm still confused as to what exactly redirect chains are and I don't know how to find where the "chains" are or how to fix them. I'm having two issues mainly:1. Temporary RedirectsI have around 100 pages on our www.twowayradiosfor.com website that are being flagged as temporary redirects. All of them have one thing in common: they are review pages (basically, when a customer clicks on the Review button to review a certain product, they are redirected to a review page for that product).URL Example:  https://www.twowayradiosfor.com/reviewhelpful.asp?ProductCode=CLS1410-COMBO&ID=44&yes=noI went into our website and set any URL containing the following as noindex:/review.aspWill that fix the issue? If yes, will I also need to do that for any URL containing /reviewhelpful.asp?2. Redirect ChainsIt seems like basically every product page on my website has this issue (over 100 pages). Here's an example of one:https://www.twowayradiosfor.com/Motorola-CLS1110-p/cls1110.htmI don't see any broken links on this page or links that redirect to another page that redirects, etc. What is causing this? Is it something on my header bar that is redirecting (since that header bar appears on every page, maybe that is why this issue shows up on a lot of pages)?I am new to Moz and still trying to figure this stuff out. I really appreciate any help. Thanks, Sawyer

                301 Redirect non existant pages

                Hi I have 100's of URL's appearing in Search Console for example: ?p=1_1 These go to on to 5_200 etc.. I have tried to do htaccess and the mod rewrite is on as I can redirect directories to the root i.e RewriteRule ^web_example(.*)$ /$1 [R=301,N,L] However I have tried all kinds of variations to redirect ?p= and either it doesn't work at all or it crashes the website. Can anyone point me in the right direction to fix this.

                301 redirect adding trailing slash to url

                I am looking into a .htacess file for a site I look after and have noticed that the urls are all 301 redirecting from a none slash directory to a trailing slashed directory/folders. e.g. www.domain.com/folder gets 301 redirected to www.domain.com/folder/ Will this do much harm and reduce the effect on the page and any links pointing to the site be lessened? Secondly I am not sure what part of my htaccess is causing the redirect. RewriteCond %{HTTP_HOST} !^www.domain.co.uk [NC] RewriteCond %{HTTP_HOST} !^$
                RewriteRule ^(.*) http://www.domain.co.uk/$1 [L,R,NE] RewriteCond %{THE_REQUEST} ^./index.php
                RewriteRule ^(.)index.php$ /$1 [R=301,L] or could a wordpress ifmodule be causing the problem? Any info would be apreciated.

                Redirect URLS with 301 twice

                Hello, I had asked my client to ask her web developer to move to a more simplified URL structure. There was a folder called "home" after the root which served no purpose. I asked for the URLs to be redirected using 301 to the new URLs which did not have this structure. However, the web developer didn't agree and decided to just rename the "home" folder "p". I don't know why he did this. We argued the case and he then created the URL structure we wanted. Initially he had 301 redirected the old URLS (the one with "Home") to his new version (the one with the "p"). When we asked for the more simplified URL after arguing, he just redirected all the "p" URLS to the PAGE NOT FOUND.  However, remember, all the original URLs are now being redirected to the PAGE NOT FOUND as a result. The problems I see are these unless he redirects again: The new simplified URLS  have to start from scratch to rank 2)We have duplicated content - two URLs with the same content Customers clicking products in the SERPs will currently find that they are being redirect to the 404 page. I understand that redirection has to occur but my questions are these: Is it ok to redirect twice with 301 - so old URL to the  "p" version then to final simplified version. Will link juice be lost doing this twice? If he redirects from the original URLS to the final version missing out the "p" version, what should happen to the "p" version - they are currently indexed. Any help would be appreciated. Thanks

                301 Redirects in subfolders

                Hi, we're making our site into a static site but I would like to transfer the Google juice. Most of the links and database exist on subfolders though. Could I simply do 301 redirects on the subfolders and retain the value or does it have to be on the full domain?

                Index.php and 301 redirect with Joomla

                Hi, I'm running Joomla 1.7 with SEF on and I'm trying to do a htaccess redirect which fails. I have approximately 100 in effect so far and all working fine, but I have one snag. Index.php is not working as I need it to when it's redirected to www.myurl.com/ If I turn on index.php redirect to root using this code #index.php to root
                RewriteCond %{HTTP_HOST} ^myurl.com$ [OR]
                RewriteCond %{HTTP_HOST} ^www.myurl.com$
                RewriteRule ^index.php$ "http://www.myurl.com/" [R=301,L] And then go to www.myurl.com/test.html I'm redirected to the homepage. I think this is because all pages are index.php in joomla. SEOMOZ and Google both think that index.php and root are duplicate pages. Does anyone have any advice for overcoming this? Thanks, Adam

                Any way around buying hosting for an old domain to 301 redirect to a new domain?

                Howdy. I have just read this QA thread, so I think I have my answer. But I'm going to ask anyway! Basically DomainA.com is being retired, and DomainB.com is going to be launched. We're going to have to redirect numerous URLs from DomainA.com to DomainB.com. I think the way to go about this is to continue paying for hosting for DomainA.com, serving a .htaccess from that hosting account, and then hosting DomainB.com separately. Anybody know of a way to avoid paying for hosting a .htaccess file on DomainA.com? Thanks!
