301 redirect syntax for htaccess
-
I'm working on some htaccess redirects for a few stray pages and have come across a few different varieties of 301s that are confusing me a bit....Most sources suggest:
Redirect 301 /pageA.html http://www.site.com/pageB.html
or using some combination of:
RewriteRule + RewriteCond + RegEx
I've also found examples of:
RedirectPermanent /pageA.html http://www.site.com/pageB.html
I'm confused because our current htaccess file has quite a few (working) redirects that look like this:
Redirect permanent /pageA.html http://www.site.com/pageB.html
This syntax seems to work, but I'm yet to find another Redirect permanent in the wild, only examples of Redirect 301 or RedirectPermanent
Is there any difference between these? Would I benefit at all from replacing Redirect permanent with Redirect 301?
-
There is no difference between "Redirect 301", "Redirect permanent" and "RedirectPermanent". It is clear from mod Alias documentation:
"This directive makes the client know that the Redirect is permanent (status 301). Exactly equivalent to
Redirect permanent
." "permanent - Returns a permanent redirect status (301) indicating that the resource has moved permanently."But, these directives are really confusing, because they are not page to page, but directory to directory. For example:
Redirect 301 /a-very-old-post/ http://yoursite.com/a-very-new-post/
Surprisingly, it will redirect all old subpages to new subpages. In particular it will redirect /a-very-old-post/page1 to /a-very-new-post/page1 Therefore better to use RedirectMatch or RewriteCond+RewriteRule for page by page redirections and for redirections with query strings.

In **apache **"permanent" "RedirectPermanent" is the same as "Redirect 301"
By default, the "Redirect" directive establishes a 302, or temporary, redirect.
If you would like to create a permanent redirect, you can do so in either of the following two ways:
- Redirect 301 /oldlocation http://www.domain2.com/newlocation
- Redirect permanent /oldlocation http://www.domain2.com/newlocation

https://www.aleydasolis.com/htaccess-redirects-generator/
If no <var>status</var> argument is given, the redirect will be "temporary" (HTTP status 302). This indicates to the client that the resource has moved temporarily. The <var>status</var> argument can be used to return other HTTP status codes:
<dl> "permanent" & "Redirect 301"</dl>
<dl>
<dd>Returns a permanent redirect status (301) indicating that the resource has moved permanently.</dd>
"temp"</dl>
<dl>
<dt>Returns a temporary redirect status (302). This is the default.</dt>
"seeother"</dl>
<dl>
<dd>Returns a "See Other" status (303) indicating that the resource has been replaced.</dd>
"gone"</dl>
<dl>
<dd>Returns a "Gone" status (410) indicating that the resource has been permanently removed. When this status is used the <var>URL</var> argument should be omitted.</dd>
</dl>

Regular expressions
Rewrite rules often contain symbols that make a regular expression (regex). This is how the server knows exactly how you want your URL changed. However, regular expressions can be tricky to decipher at first glance. Here's some common elements you will see in your rewrite rules, along with some specific examples.
- ^ begins the line to match.
- $ ends the line to match.
- So, ^folder1$ matches folder1 exactly.
- . stands for "any non-whitespace character" (example: a, B, 3).
- * means that the previous character can be matched zero or more times.
- So, ^uploads.*$ matches uploads2009, uploads2010, etc.
- ^.*$ means "match anything and everything." This is useful if you don't know what your users might type for the URL.
- () designates which portion to preserve for use again in the $1 variable in the second string. This is useful for handling requests for particular files that should be the same in the old and new versions of the URL.

I have a question about the impact of a root domain redirect on site-wide redirects and slugs.
I have a question about the impact (if any) of site-wide redirects for DNS/hosting change purposes. I am preparing to redirect the domain for a site I manage from https://siteImanage.com to https://www.siteImanage.com. Traffic to the site currently redirects in reverse, from https://www.siteImanage.com to https://siteImanage.com. Based on my research, I understand that making this change should not affect the site’s excellent SEO as long as my canonical tags are updated and a 301 redirect is in place. But I wanted to make sure there wasn’t a potential consequence of this switch I’m not considering. Because this redirect lives at the root of all the site’s slugs and existing redirects, will it technically produce a redirect chain or a redirect loop? If it does, is that problematic? Thanks for your input!

301 redirect: canonical or non canonical?
Hi, Newbie alert! I need to set up 301 redirects for changed URLs on a database driven site that is to be redeveloped shortly. The current site uses canonical header tags. The new site will also use canonical tags. Should the 301 redirects map the canonical URL on the old site to the corresponding canonical for the new design . . . or should they map the non canonical database URLs old and new? Given that the purpose of canonicals is to indicate our preferred URL, then my guess is that's what I should use. However, how can I be sure that Google (for example) has indexed the canonical in every case? Thx in anticipation.

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

Loss of search engine positions after 301 redirect - what went wrong?!?
Hi Guys After adhering to the On Page optimisation suggestions given by SEOmoz, we redirected some of old urls to new ones. We set 301 redirects from the old pages to new on a page by page basis but our search engine ranking subsequently fell off the radar and lost PR. We confirmed redirection with fiddler and it shows 301 permanent redirect on every page as expected. To manage redirection using a common code logic we executed following: In Http module, using “rewrite path” we route “all old page requests” to a page called “redirect.aspx? oldpagename =[oldpagename]”. This happens at server side. In redirect.aspx we are redirecting from old page to new page using 301 permanent redirect. In the browser, when old page is requested, it will 301 redirect to new page. In hope we and others can learn from our mistakes - what did we do wrong ?!? Thanks in advance. Dave - www.paysubsonline.com

Do search engines treat 307 redirects differently from 302 redirects?
We will need to send our users to an alternate version of our homepage for a few hours for a certain event. The SEO task at hand is to minimize the chance of the special homepage getting crawled and cached in the search engines in place of our normal homepage. (This has happened in the past so the concern is not imaginary.) Among other options, 302 and 307 redirects are being discussed. IE, redirecting www.domain.com to www.domain.com/specialpage. Having used 302s and 301s in the past, I am well aware of how search engines treat them. A 302 effectively says "Hey, Google! Please get rid of the old content on www.domain.com and replace it with the content on /specialpage!" Which is exactly what we don't want. My question is: do the search engines handle 307s any differently? I am hearing that the 307 does NOT result in the content of the second page being cached with the first URL. But I don't see that in the definition below (from w3.org). Then again, why differentiate it from the 302? 307 Temporary Redirect The requested resource resides temporarily under a different URI. Since the redirection MAY be altered on occasion, the client SHOULD continue to use the Request-URI for future requests. This response is only cacheable if indicated by a Cache-Control or Expires header field. The temporary URI SHOULD be given by the Location field in the response. Unless the request method was HEAD, the entity of the response SHOULD contain a short hypertext note with a hyperlink to the new URI(s) , since many pre-HTTP/1.1 user agents do not understand the 307 status. Therefore, the note SHOULD contain the information necessary for a user to repeat the original request on the new URI. If the 307 status code is received in response to a request other than GET or HEAD, the user agent MUST NOT automatically redirect the request unless it can be confirmed by the user, since this might change the conditions under which the request was issued.

How to safely reduce the number of 301 redirects / should we be adding so many?
Hi All, We lost a lot of good rankings over the weekend with no obvious cause. Our top keyword went from p3 to p12, for example. Site speed is pretty bad (slower than 92% of sites!) but it has always been pretty bad. I'm on to the dev team to try and crunch this (beyond image optimisation) but I know that something I can effect is the number of 301 redirects we have in place. We have hundreds of 301s because we've been, perhaps incorrectly, adding one every time we find a new crawl error in GWT and it isn't because of a broken link on our site or on an external site where we can't track down the webmaster to fix the link. Is this bad practice, and should we just ignore 404s caused by external broken URLs? If we wanted to reduce these numbers, should we think about removing ones that are only in place due to external broken URLs? Any other tips for safely reducing the number of 301s? Thanks, all! Chris
