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".

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?

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!

301 Redirects, Sitemaps and Indexing - How to hide redirected urls from search engines?
We have several pages in our site like this one, http://www.spectralink.com/solutions, which redirect to deeper page, http://www.spectralink.com/solutions/work-smarter-not-harder. Both urls are listed in the sitemap and both pages are being indexed. Should we remove those redirecting pages from the site map? Should we prevent the redirecting url from being indexed? If so, what's the best way to do that?

How to change 302 redirect from http to https
Hi gang. Our site currently has a 302 redirect from the HTTP version of the homepage to the HTTPS version of the homepage. I understand this really should be changed to a 301 redirect but I'm having a little trouble figuring out exactly how this should be done. Some places on the internet are telling me I can edit our htaccess file to specify the type of redirect, however our htaccess file seems to be missing some of the information in theirs. Can anyone tell me what needs to be changed in the htaccess file - or if there's a simpler way to change the 302 to a 301? Many thanks 🙂 htaccess: BEGIN WordPress RewriteEngine On RewriteBase / RewriteRule ^index.php$ - [L] RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule . /index.php [L] END WordPress EXPIRES CACHING ExpiresActive On ExpiresByType image/jpg "access plus 6 months" ExpiresByType image/jpeg "access plus 6 months" ExpiresByType image/gif "access plus 6 months" ExpiresByType image/png "access plus 6 months" ExpiresByType text/css "access plus 10 days" ExpiresByType application/pdf "access plus 10 days" ExpiresByType application/x-shockwave-flash "access plus 10 days" ExpiresByType image/x-icon "access plus 6 months" ExpiresDefault "access plus 2 days" EXPIRES CACHING

Max Number of 301 Redirections?
Hi, We currently made a re-design of a website and we changed all our urls to make them shorter. I made more than 300 permanent redirections but plenty more are needed since WMT is showing some more 404s from old urls that I hadn't seen because they were dynamic. The question is, please, is there a limit? I think we have more than 600 already. We don't want to create a php commando to redirect all the old ones to our home, we are redirecting them to their correspondent url. By the way, Im doing them with the 301 method in .htaccess. Thanks in advance.

Redirecting HTTP to HTTPS - How long does it take Google to re-index the site?
hello Moz We know that this year, Moz changed its domain to moz.com from www.seomoz.org
Technical SEO | | joony
however, when you type "site:seomoz.org" you still can find old urls indexed on Google (on page 7 and above) We also changed our site from http://www.example.com to https://www.example.com
And Google is indexing both sites even though we did proper 301 redirection via htaccess. How long would it take Google to refresh the index? We just don't worry about it? Say we redirected our entire site. What is going to happen to those websites that copied and pasted our content? We have already DMCAed their webpages, but making our site https would mean that their website is now more original than our site? Thus, Google assumes that we have copied their site? (Google is very slow on responding to our DMCA complaint) Thank you in advance for your reply.0 -

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!
