Redirect to http to https - Pros and Cons
-
Hi,
I know its best practice to redirect a website from http to https, instead of having many entry point to your website. When a website has been running for a long time on http and https, what are the SEO Pros and Cons of implementing a redirect from Http to Https?
-
Do you know how long it takes Google to drop pages from Google's index/cache?

(1) no, if you link to an insecure page it counts against you. Since a user or search engine would have to load and visit the insecure content to find the canonical (as that's where it would be), it does not mitigate this. You'll just have to hope it doesn't end up happening too much. Canonical tags only stop content duplication, they have no impact on SEO authority merging or insecure links
(2) If the HTTPS URLs are pretty much exactly the same as their HTTP counterparts and you 301 HTTP to HTTPS, the SEO authority should flow across to HTTPS instead. Canonical tags are not proven to do what 301s do, so you may end up in a mess with those. Most sites experience a slight dip moving from HTTP to HTTPS via proper 301s, however it's not large and doesn't last long if the 301s were done well. Staying on HTTP in the long term, you will lose a lot of rankings (gradually, over time). Since you will be constantly losing, it puts your site's progress 'on hold', so the small dip from moving from HTTP to HTTPS is the 'lesser of two evils' (IMO)
(3) Both. It will reduce the number of times Google crawls HTTP, but only after pages on HTTP are dropped from Google's index / recent cache

Thanks for the answer. However, have two more questions: (1) Will implementing canonical tags limit the temporary disruption and (2) If backlinks are pointing to http will these be lost or transferred, i.e. will https pages have less equity or inherit equity of the http pages. Finally, will redirecting to https reduce the number of times Google crawls your site or will google still crawl http until all http pages in the Google cache are removed?
-
Or in NginX format which is usually faster
-
There are no cons that I can think of, a simple script in a sites htaccess file is the best was to implement the redirection.
-
The idea of HTTPS has always been a good one, and most leading businesses implemented it a long time ago.
However, somewhat recently, Google announced that HTTPS is a ranking factor.
Obviously, that got SEOs talking about and debating the subject.
At the time, it was a very small ranking factor, affecting less than 1% of global searches. Even now, it’s not a big factor.
However, security is something that Google takes very seriously, and it’s likely to become more important in the future.
Some SEOs jumped right on it and made the switch.

This is a very solid answer. One additional point is that without a forced structure, Google can 'catch out' your secure site linking to your insecure site. Say you have a blog and a post in the blog links to one of your pages, that link is probably created as 'absolute' in your CMS. So suddenly, when you load that blog post on HTTPS, you can see a link pointing to HTTP. Google doesn't like links pointing to insecure content, so over time the situation snowballs and you lose a lot of trust
-
If your current pages can be accessed by http and by https, and if you don't have canonicals or redirects pointing everything to one version or the other, then one very significant "con" for that approach is that you are splitting your link equity. So, if the http page has 50 inbound links, and the https has another 50, you would do better to have one page with 100 inbound links.
Another difference is how browsers show/warn about non-secure pages. As well as any ranking factor they may associate with secure. Again, in favor of redirecting http to https. The visual handling can also impact conversion rates and bounce rates, which can in turn impact ranking.
As far as cons to redirecting, one would be that you might expect a temporary disruption to rankings. There will likely be a bit of a dip, short term. Another is that you will need to remove and then be careful about accidentally adding any non-secure resources (like images) on the https pages, which will then issue a warning to visitors as well as possibly impacting ranks. There is some consensus that redirects (and canonical links) do leak a very small amount of link equity for each hop they take. So, that's another "con". But my recent experiences doing this with two sites have been that after the temporary "dip" of a couple of months, if done properly, the "pros" outweigh the "cons".

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?

Should we set up redirects for all deleted TAGS?
We recently found our site had 65,000 tags (yes 65K). In an effort to consolidate these we've started deleting them. MOZ is now reporting a heap of 404 errors for tag pages. These tag pages should not have links to them so not sure how come they're being crawled. Any suggestions from experience in this area would be useful.

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 | Feb 21, 2023, 1:08 PM | 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 -
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.

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
