Redirection chain and Javascript Redirect
-
Hi,
A redirection chain is usually defined as a page redirecting to another page which itself is another redirection.
URL1 ---(301/302)---> URL2 ---(301/302)---> URL3
But what about Javascript redirect? They seem to be a different beast:
URL1 ---(301/302)---> URL2 ---(200 then Javascript redirect)---> URL3
From what I know if the javascript redirect is instant Google counts it as a 301 permanent redirection, but I'm still not sure about if this counts as a redirection chain.
Most of the tools (such as moz) only see the first redirection.
So is that scenario a redirection chain or no?

It's a delicate balance between efficient routing and ensuring seamless transitions, where every decision shapes the user's path and perception. myvirtualworkplace

A JavaScript redirect, on the other hand, is a redirect that occurs using JavaScript code embedded in a webpage. Instead of relying on server-side redirects, JavaScript redirects are triggered when the page loads or when certain conditions are met, and they instruct the browser to navigate to a different URL. They can be used for various purposes, such as redirecting users after a certain amount of time, after a form submission, or based on user interactions.

I appreciate your detailed explanation. To enhance accuracy in tracing redirects, ensure a cohesive sequence. Consider using a unified approach for hash numbers, perhaps generating a unique identifier for each transition. Additionally, refine the code logic to account for different redirection techniques, ensuring a seamless and connected mapping of the entire journey from A to D. If possible, share snippets of your code for more targeted guidance. shopify website design servicee austin

Thank you for the valuable feedback. While the current code successfully executes, it lacks accuracy in tracing the redirect sequence. The issue stems from the disjointed nature of the captured redirects, as seen in the isolated transitions from A to B, B to C, and C to D, where randomly generated hash numbers (channel_1 and channel_2) are utilized. This disrupts the continuity of the redirect chain, resulting in an inaccurate representation of the actual progression from A through D.
The objective is to effectively track the entire journey, encompassing transitions from A to B to C to D, across various redirection techniques such as meta-refresh, JavaScript, and HTTP redirects. I would greatly appreciate your guidance on refining the code to maintain the integrity of the redirect sequence, ensuring a connected and sequential mapping of the redirection process. Liteblue

In the scenario you described, where there is a sequence of redirects involving both HTTP redirects (301/302) and a JavaScript redirect, it can be considered a redirection chain. The key point is that each step in the sequence contributes to the final destination of the URL.
In your example:
- URL1 redirects to URL2 using an HTTP 301/302 status code.
- URL2, after an HTTP 200 response, triggers a JavaScript redirect to URL3.
From Google's perspective, if the JavaScript redirect is instantaneous and does not introduce a delay, it might treat it similarly to a traditional 301 permanent redirect. However, it's important to note that search engines may interpret JavaScript redirects differently, and their behavior may evolve over time.
Tools like Moz may sometimes focus on the initial HTTP redirect and not delve into subsequent steps, potentially overlooking the complete redirection chain. Therefore, discrepancies in what different tools report could occur.
For a more comprehensive understanding, you might consider using tools or methods that specifically analyze JavaScript-based redirects or inspect the network requests in a browser's developer tools to see the entire redirection sequence. This way, you can get a clearer picture of how search engines and various tools interpret the entire redirection chain, including both HTTP and JavaScript redirects.

Thank you for the insightful feedback. While the current code executes successfully, it falls short in accurately tracing the redirect sequence. The issue lies in the disjoint nature of the captured redirects, exemplified by the isolated transitions A->B, B->C, and C->D, where the hash numbers (channel_1 and channel_2) are generated randomly. This disrupts the continuity of the redirect chain, failing to reflect the actual progression from A through D. The goal is to effectively track the entire journey, A->B->C->D, across different redirection techniques such as meta-refresh, JavaScript, and HTTP redirects. Could you provide guidance on how to refine the code to maintain the integrity of the redirect sequence, ensuring a connected and sequential mapping of the redirection process?

Thank you for your feedback. While the code is currently functional, it doesn't yield the expected outcome. The recorded redirect chain appears disjointed, capturing transitions like A->B (channel_1 -> channel_2), B->C (channel_1 -> channel_2), and C->D (channel_1 -> channel_2). The issue lies in the randomly generated hash numbers (channel_1 and channel_2), preventing the proper linkage of the redirect chain. The goal is to accurately capture sequential events such as A->B->C->D, considering various redirection methods like meta-refresh, JavaScript, and HTTP. How can I modify the code to implement this strategy and ensure the redirection chain is connected as intended?

thx, the code works, but not as expected: A->B->C->D (channel_1 -> channel_2 -> channel_3 -> channel_4).
In my case it will record a redirect chain of A->B->C->D like:
A->B (channel_1 -> channel_2), than B->C (channel_1 -> channel_2), C->D (channel_1 -> channel_2); where channel_1 & channel_2 are random hash numbers.
So I can not link the chain together. that would be the strategy to capture the chain of events (while the pages redirect using, meta-refresh, javascript, http...)? Liteblue USPS

window.location.replace('http://example.com');
It's better than using window.location.href = 'http://example.com';
Using replace() is better because it does not keep the originating page in the session history, meaning the user won't get stuck in a never-ending back-button fiasco.
If you want to simulate someone clicking on a link, use window.location.href
If you want to simulate an HTTP redirect, use window.location.replace
You can use assign() and replace methods also to javascript redirect to other pages like the following:
location.assign("http://example.com");
The difference between replace() method and assign() method(), is that replace() removes the URL of the current document from the document history, means it is not possible to use the "back" button to navigate back to the original document. So Use the assign() method if you want to load a new document, andwant to give the option to navigate back to the original document.

301 Redirects Showing As 307 Redirects
Hi, Our clients are adamant that they have set up 301 permanent redirects on their websites, but when we check using Screaming Frog and various online HTTP status code checkers they are showing as 307 temporary redirects. Examples;

301 Redirect Best Practices
Hi SEOs, Question about ranking/redirects. If I have a particular page that is already ranking for a couple KWs in top SERPs, but know there are higher volume KWs I can optimize for should I just leave it as is or change the URL key and redirect for the time being until Google re-indexes. Example:
Technical SEO | | IceIcebaby
current URL: www.example.com/action/best-movies
new URL: www.example.com/action/best-action-movies
(the current would be ranking for "best action moves" whereas the new would include the actual "best action movies" KW) Let me know if I can clarify, thank you!0 -
Canonical redirects
Hello, I have a quick question: I use wordpress for my website. I have a plugin for translating the website in other languages. Thus, I have 2 versions of urls, one with /en, one without (original languale). This has been seen as duplicate content. I have been advised that the best to do is to use canonical redirect. Should I use it on the general header.php (the only header I can find in the CMS), or should I redirect each page singularly? I believe the second is the best way, but I can't find headers and txt documents for each page in my FTP. As well I have seen this post, in which is explained that canonical redirects can be done directly in the general header.php http://www.bin-co.com/blog/2009/02/avoid-duplicate-content-use-canonical-url-in-wordpress-fix-plugin/ Is it true? You have any suggestion?

Redirects in site map
I have a site with the ace/sef ( creates friendly URLS) in a large data base site. It creates a site map dynamically. Yet I realize one issue which I am trying to think through. I recently changed my urls to include an ID number example: homepage/houses/1134-big-blue-house The prior url was: homepage/houses/big-blue-house the original url above redirects to the new one with the ID like I want. However the site map has both URLS in it which go to same page I am not sure but it seems rather stupid to have the new URL and OLD redirected URL in the site map. Yet beside stupid I am wondering if this is duplicate content and will cause a penalty from the google bot. What is your opinion ?

Will a 303 redirect hurt us?
Our membership based website is using a 303 redirect to handle the redirection of users back to the login page when those users try to access a page behind the logged in firewall. Said another way, if a user is not yet logged in, we redirect them to the login page using a 303 redirection. Unfortunately, Googlebot get this redirection too and after a recent audit, we're thinking this isn't the best way to handle this. For pages which require a user to login first, should we: A) index and 303 redirect to the login page (what we are currently doing) B) index and 302 redirect to the login page C) noindex those pages D) Remove any special treatment and let Google figure it out. Thanks in advance for your help! David

Redirects
If I redirect page A to page B does page A need to exist before Google sees the redirect. Or can I just put up a redirect and delete page A. If the page doesn't need to exist: You have all your redirects in place for a website. You want this website to redirect to another website. You completely delete the website and put up the htaccess, there should be no problem with this, because the redirects are in place correct? Thanks

Compare URLs with 302 redirects
Hello I have a store which was developed in Magento. I have about 8300 errors like this: URL: http://www.theprinterdepo.com/catalog/product_compare/add/product/100/uenc/aHR0cDovL3d3dy50aGVwcmludGVyZGVwby5jb20vcHJpbnRlci1wYXJ0cy5odG1sP3A9NA,,/ 1 Warning 302 (Temporary Redirect) Found 3 days ago <dl> <dt>Redirects to</dt> <dt>http://goo.gl/XMaZg</dt> <dd>Description</dd> <dd>Using a 302 redirect will cause search engine crawlers to treat the redirect as temporary and not pass any link juice (ranking power). We highly recommend that you replace 302 redirects with 301 redirects.</dd> </dl> <a class="more expanded">Minimize</a> These URLs, are generated by magento by the COMPARE feature. In my store we bought an extension called SEO Enterprise Suite and I asked the developers(www.mageworx) about this error. Their answer is: Sorry for the late reply. Our extension adds NOINDEX,FOLLOW tag to compare and cookies pages so that they won't be indexed. I do not think that these redirects can hurt your SEO because these pages won't be indexed at all. The question is: What should I do? Is there anyway that SEOMOZ ignores these URLs? What should I do next, I just dont like to have that HIGH number of errors and warnings. Thank you

302 Redirects for Minor Pages
301 redirects are clearly preferable to 302 redirects for pages that need to be indexed by search engines. If I have 302 redirects to minor pages not getting much traffic regardless of the code, how important (if at all) is changing the redirects to 301? Thanks!
