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".

Missing 301 redirects
I just had a developer friend call me in a panic, because they had gone live with a new site and found out (the hard way) that they had missed some pages on their 301 redirects. So the pages are appearing in Google but serving 404s. Ouch! So their question was: other than running a report for 404 errors in something like Screaming Frog, is there a way to hunt down ONLY pages serving 404s, then export to CSV so they can be redirected? Anyone got any tricks up their sleeve?

How should I set up a domain redirect
A client has 2 domains that he wants to use for the same site. At the moment one domain is just an abbreviation of the main domain (not sure why) as follows: www.mygreatpropertycompany.com
Technical SEO | | davidmaxwell
www.mgpc.com (just redirects to the above) He is complaining that when he searches for 'mpc' there are no results (at all) so I'm wondering what the best approach is.There is currently nothing on the main domain that refers to 'mgpc' in it's abbreviated sense - the only place it's being used is the company's email addresses (info@mgpc.com). The redirect is simply a html file in the root of www.mgpc.com as follows: Is there anything I can do to help him out? (this is one of those 'doing a friend a favour' tasks!) Thanks!0 -

Redirecting Several Hundred Pages
As of May 21st 2013 (Penguin 2.0 update) we hit a triple-header and I think we can now officially dubbed the "KING OF GOOGLE PANALTIES"! 😞 -July 2012 - recieved 2 "Unatural Links" email -April 2012 - 20% traffic hit -May 21st 2013 - 35% traffic hit We have/had lots of very low quality links using the same anchor text as well as about 150 very low quality articles and almost 100 categories w/several hundred products that recieved little to no traffic. We have spent the last several weeks cleaning up our link profile and were highly successful in getting most of them removed and have kept detailed reports for our Reconsideration Request for the manual "Unatural Links" penalty. We have also went a step further and have completely redesigned the site that is now much faster/better on-page seo with new, high quality articles and are removing all the low quality articles, categories and products but we are unclear what to do with these. Which brings me to my question. Should we redirect these pages back to the home page or just let them go to 404 error? I have been doing lots of reading on this subject but there doesnt seem to be any good answers. From what I read, neither are good choices and I cannot decide between the lesser of the 2 evil's ..so any help with this would be greatly apreciated! Note:

-These category and product pages have absolutly no inbound links (link benefit) and in my opinion are only sucking off link juice and generating little to no revenue. There are also no similar categories or products that these could be redirected to. For example, redirecting dog toys to the dog bed category just sounds like it would increase our bounce rate. -Again, the articles also have no link benefit and only a small handful of the articles actually generate any traffic to speak of (several thousand visitors per year) and the rest generate less than 1000 visitors per year. All have high bounce rates and low conversions. It would be nice to keep them live as I think some are okay and could be rewritten/re-purpose over time but maybe in light of our Panda penalty it might be better to just to save them offline, let them go to 404 errors and rewritten/re-purpose them another time? -We did create a very nice 404 page with category navigation and huge search bar so I am leaning more toward this option.

IP redirects
My website, on a .com domain, displays a different language/content depending on the IP of the user. For example, if someone is browsing my web from Spain, it will show the spanish content, and so on. Does anyone has an idea on how will Google index my pages? Their servers being located in the US, I assume the bot will only crawl and index the english content. How can I tell the bots to do the same for the other languages/content? Thanks!

Redirecting According to the occasion
We have loads of different departments that relate to specific occasions (e.g. Christmas, mothers day, father day etc), they all have good PR and inbound links etc and most of them rank well for the specific occasion. What I was thinking is that I could redirect all of the occasions that aren’t in use and send the traffic to the valid occasion live at the moment. So I would 301 all the Christmas pages to our valentine’s day main page. Then once valentines is gone I will redirect Christmas and valentines to the mothers day main page and so on. So this would be constantly switching as different occasions come along. Can you see any possible negative problems? Is there any chance that if I redirect Christmas for example, and then when Christmas comes we remove the redirect, could it harm the Christmas page?

Question about domain redirects
One of my clients has an odd domain redirect situation. See if you can get your head round this: Domain A is set-up as a domain alias of Domain B Entering domain A or domain B takes you to default.asp on domain B. The default.asp includes VB script to check the HTTP_HOST variable. It checks whether the main doman name for domain A is present in the HTTP_HOST and if so redirects it to domain A/sub-folder/index.htm. If not present it redirects to domain B/index.htm. In both cases the redirect uses a response.Redirect clause. I think what is trying to be achieved is to redirect requests to Domain A to a sub-folder of Domain B. It works but seems extremely convoluted. Can anyone see problems with this set-up? Will link juice be lost along the redirect paths?
