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?

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.

WPEngine Causing Redirect Chain
Hi guys, Had a quick question that I wanted to verify here. After reviewing a Moz report we received some redirect chain error on all of our sites hosted with WPEngine. We noticed that the redirect chain appears to be coming from how the domains are configured in their control panel. Essentially, there is a redirect: from staging/temp -> to live from non-www -> to www SSL redirect from http -> https The issue here is that the non-www is redirecting to www and then redirected again to https://www According to support the only way to get rid of this error is to drop the www version of the domain and to host everything under https://domain.com. To me it seems very odd that you cannot just go from http://non-www to https://www in just 1 301 redirect. Has anyone else experienced this or am I just not looking at the situation correctly?

301 redirects delay in picking up
Hi I have been involved in the redesign/development of a website which has up until now had a lot of international traffic. On day of migration I uploaded all the 301 redirects to the website (wordpress) using Simple 301 redirect plugin. I tested a number of them and they appeared to be working. I also submitted the new sitemaps to Search Console. Since migration international traffic - particularly from countries such as india, Phillipines, Sri Lanka etc have significantly dropped off whereas the local traffic and some of the international traffic such as USA has remained fairly consistent. Looking at Analytics and entrances recently it appears as though search results are/were showing a number of pages with 404's (one in particular which received significant traffic and for which I had created a 301 redirection) - I have checked this page using the old url and it re-directs correctly for me and today asked a colleague in India to also check - he is getting the redirection fine. Does Google.in take a significantly longer time to pick these up in search results? Or am I missing something?

Can I remove 301 redirects after some time?
Hello, We have an very large number of 301 redirects on our site and would like to find a way to remove some of them. Is there a time frame after which Google does not need a 301 any more? For example if A is 301 redirected to B, does Google know after a while not to serve A any more, and replaces any requests for A with B? How about any links that go to A? Or: Is the only option to have all links that pointed to A point to B and then the 301 can be removed after some time? Thank you for you you help!

Delete 301 redirected pages from server after redirect is in place?
Should I remove the redirected old pages from my site after the redirects are in place? Google is hating the redirects and we have tanked. I did over 50 redirects this week, consolidating content and making one great page our of 3-10 pages with very little content per page. But the old pages are still visible to google's bot. Also, I have not put a rel canonical to itself on the new pages. Is that necessary? Thanks! Jean

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 do I redirect index.html to the root / ?
The site I've inherited had operated on index.html at one point, and now uses index.php for the home page, which goes to the / page. The index.html was lost in migrating server hosts. How do I redirect the index.html to the / page? I've tried different options that keep giving ending up with the same 404 error. I tried a redirect from index.html to index.php which ended in an infinite loop. Because the index.html no longer exists in the root, should I created it and then add a redirect to it? Can I avoid this by editing the .htaccess? Any help is appreciated, thanks in advance!

301 Redirect vs Domain Alias
We have hundreds of domains which are either alternate spelling of our primary domain or close keyword names we didn't want our competitor to get before us. The primary domain is running on a dedicated Windows server running IIS6 and set to a static IP. Since it is a static IP and not using host headers any domain pointed to the static IP will immediately show the contents of the site, however the domain will be whatever was typed. Which could be the primary domain or an alias. Two concerns. First, is it possible that Google would penalize us for the alias domains or dilute our primary domain "juice"? Second, we need to properly track traffic from the alias domains. We could make unique content for those performing well and sell or let expire those that are sending no traffic. It's not my goal to use the alias domains to artificially pump up our primary domain. We have them for spelling errors and direct traffic. What is the best practice for handling one or both of these issues?
