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.

Redirect and ranking issue
Hi there - was wondering whether someone might be able to help. For a period of a day and a half, all the traffic to our website's blog articles were mistakenly being redirected to our homepage. A number of these articles ranked in the top 5 in Google worldwide for their targeted keywords, so this was a considerable amount of organic traffic that was instantly being redirected. It was a strange site glitch and our web team rectified the error, but now all these articles have disappeared from Google rankings (not visible anywhere in the first five pages). I'm presuming this must be linked to this redirect issue - we've been advised to wait and see whether Google restores these rankings, but I'm still concerned as to whether this represents a more serious problem? We have re-indexed the pages we are most concerned about, but am not sure whether there is anything else obvious we should think to do. If anyone has any thoughts, I'd be happy to hear them!

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?

Backlinks that go to a redirected URL
Hey guys, just wondering, my client has 3 websites, 2 of 3 will be closed down and the domains will be permanently redirected to the 1 primary domain - however they have some high quality backlinks pointing the domains that will be redirected. How does this effective SEO? Domain One (primary - getting redesign and rebuilt) - not many backlinks
Technical SEO | | thinkLukeSEO
Domain Two (will redirect to Domain One) - has quality backlinks
Domain Three (will redirect to Domain One) - has quality backlinks When the new website is launched on Domain One I will contact the backlink providers and request they update their URL - i assume that would be the best.0 -
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?

Is there a limit to Internal Redirect?
I know Google says there is no limit to it but I have seen on many websites that too many 301 redirects can be a problem and might negatively affect your rankings in SERPs. I wanted to know especially from people who worked on large ecommerce site. How do they manage internal redirect from one URL to other and how many according to you are too many. I mean if you get a website that contain 300 plus 301 redirections within the website, how will you deal with that? Please let me know if the question is not clear.

What to do with 302 redirects being indexed
Hi there, Our site's forums include permalinks that for some reason uses an intermediary URL that 302 redirects to the URL with the permalink anchor. For example: http://en.tradimo.com/learn/chart-analysis/time-frames/ In the comments, there is a permalink to the following URL; en.tradimo.com/co/50c450005f2b949e3200001b/ (there is no content here, and never has been). This URL 302 redirects to the following final URL: http://en.tradimo.com/learn/chart-analysis/time-frames/?offset=0&limit=20#50c450005f2b949e3200001b The problem is, Google is indexing the redirect URL (en.tradimo.com/co/50c450005f2b949e3200001b/) and showing duplicate content even though we are using the nofollow tag on these links. Ideally, we would directly use the last link rather than redirecting. Alternatively, I'd say a 301 redirect would be preferable. But if both aren't available, is there a way to get these pages out of the index? Is the canonical tag the best way? I really wish I could just add /co/ to the robots.txt file, but I think they would still be in the index, right? Thanks for your help!
