Domain Level Redirects - HTTP and HTTPS
-
About 2 years ago (well before I started with the company), we did an http=>https migration. It was not done correctly. The http=>https redirect was never inserted into the .htaccess file. In essence, we have 2 websites. According to Google search console, we have 19,000 HTTP URLs indexed and 9,500 HTTPS URLs indexed.
I've done a larger scale http=>https migration (60,000 SKUs), and our rankings dropped significantly for 6-8 weeks. We did this the right way, using sitemaps, and http and https GSC properties. Google came out recently and said that this type of rankings drop is normal for large sites.
I need to set the appropriate expectations for management. Questions:
- How badly is the domain split affecting our rankings, if at all? Our rankings aren't bad, but I believe we are underperforming our backlink profile. Can we expect a net rankings gain when the smoke clears? There are a number of other technical SEO issues going on as well.
- How badly will our rankings drop (temporarily) and for how long when we add the redirect to the .htaccess file?
- Is there a way to mitigate the rankings impact? For example, only submitting partial sitemaps to our GSC http property?
Has anyone gone through this before?

Interesting Answer Paul,
I am currently in a similar boat, just a lot smaller situation, but we haven't indexed our https pages with Google Search Console yet, currently fixing errors with our site first. Should I finishing fixing our http page and then do an https redirect and then remove the sitemaps from the http search console or will google be clever enough to realise?
Regards
Chris

Google has said that when they find the same page under both HTTP and HTTPS, they will try to return the HTTPS page in search (certain circumstances ap[ply). But the fact remains that you are making the search engines "figure it out" instead of giving explicit directives that ensure the correct behaviour.
I suspect the HTTPS split has already done its damage, especially with regards to backlinks now pointing at two destinations and thus splitting the authority. Which is likely the cause for your suspicion of the underperforming backlink profile.
So the process of getting the HTTP dupe resolved to HTTPS with the redirect should start delivering improvement as soon as the new crawling/indexing gets done. I strongly suspect this improvement will offset most if not all of the effect of the new HTTPS redirects.
There's no way to estimate the effect of the addition of the proper HTTPS redirect, but given that you're already in a compromised hybrid state, my strong suspicion is that it will actually improve the situation without much temporary drop at all. In essence, you've already experienced the negative pressure. The changes will serve to start to reduce the negative pressure immediately.
But this is my best assumptions. I haven't done an HTTPS redirect correction on such a large site. On the smaller sites I've fixed though, the uptick happened within a week or two. Though not dramatic improvements still beneficial.
The other thing to be aware of: Google has stated that when they do the reindexing to HTTPS, it's essentially like recrawling a new site. So they apply all the tests and quality checks to all pages. So if you have existing issues to clean up, do that before final implementation of the HTTPS redirect.
I'd be really interested to follow your results on this - sounds like a solid opportunity for a case study!
Hope that helps;
Paul

How Can I Redirect an Old Domain to Our New Domain in .htaccess?
There is an old version of http://chesapeakeregional.com still floating around the web here: http://www.dev3.com.php53-24.dfw1-2.websitetestlink.com/component/content/category/20-our-services. Various iterations of this domain pop up when I do certain site:searches and for some queries as well (such as "Diagnostic Center of Chesapeake"). About 3 months ago the websitetestlink site had files and a fully functional navigation but now it mostly returns 404 or 500 errors. I'd like to redirect the site to our newer site, but don't believe I can do that in chesapeakeregional.com's .htaccess file. Is that so and would I need access to the websitetestlink .htaccess to forward the domain? Note* I (nor anyone else in our organization) has the login for the old site. The new site went live about 9 months before I arrived at the organization and I've been slowly putting the pieces together since arriving.

Switching from HTTP to HTTPS: 301 redirect or keep both & rel canonical?
Hey Mozzers, I'll be moving several sites from HTTP to HTTPS in the coming weeks (same brand, multiple ccTLDs). We'll start on a low traffic site and test it for 2-4 weeks to see the impact before rolling out across all 8 sites. Ideally, I'd like to simply 301 redirect the HTTP version page to the HTTPS version of the page (to get that potential SEO rankings boost). However, I'm concerned about the potential drop in rankings, links and traffic. I'm thinking of alternative ways and so instead of the 301 redirect approach, I would keep both sites live and accessible, and then add rel canonical on the HTTPS pages to point towards HTTP so that Google keeps the current pages/ links/ indexed as they are today (in this case, HTTPS is more UX than for SEO). Has anyone tried the rel canonical approach, and if so, what were the results? Do you recommend it? Also, for those who have implemented HTTPS, how long did it take for Google to index those pages over the older HTTP pages?

Client wants a seperate .tv domain for their media/videos instead of a subdomain/subfolder. What is the best way to pass of link equity to a new domain?
We have a client that wants to place their video content on a .tv tld instead of a subfolder/subdomain in their .com website. They believe that the .tv domain will better represent the media experience of their business. We can understand this client's position however we are concerned about their .tv domain will lose out on the link equity if it were no longer placed in the .com's subdomain/subfolder. Here are our questions: 1. What would be the best way to pass of link equity from .com website to a new .tv domain? Should we just have a video link on the .com website that 301 directs to the new .tv domain? 2. Is there any SEO benefit of having a .tv domain for Google Video queries or even Youtube? 3. Is there any long term value of having two different websites? For link equity purposes we understand that it would be better if everything was in a .com. However is a .tv domain ideal for a better representation of their media content? We appreciate any feedback.

Duplicate pages with http and https
Hi all, We changed the payment part of our site to https from http a while ago. However once on the https pages, all the footer and header links are relative URLs, so once users have reached the payment pages and then re-navigate back to other pages in our website they stay on https. The build up of this happening has led to Google indexing all our pages in https (something we did not want to happen), and now we are in the situation where our homepage listing on Google is https rather than http. We would prefer the organic listings to be http (rather than https) and having read lots on this (included the great posts on the moz (still feels odd not refering to it as seomoz!) blog around this subject), possible solutions include redirects or a canoncial tags. My additional questions around these options are: 1. We already have 2 redirects on some pages (long story), will another one negatively impact our rankings? 2. Is a canonical a strong enough hint to Google to stop Google indexing the https versions of these page to the extent that out http pages will appear in natural listings again? If anyone has any other suggestions or other ideas of how to address this issue, that would be great! Thanks 🙂 Diana

Redirection to mobile site
Calling all SEO ninjas! I'm currently developing single web pages for various clients which function as abbreviated versions of their main websites. They are all related & under a single domain. When a user visits these pages on a mobile device, CSS is used to display mobile friendly versions of these pages. My clients are thrilled with these mobile versions and now want to also redirect mobile visitors from their main site (which is not mobile optimised) to these pages. My questions are: Are there any negative implications if we did this? ie. redirecting to a different domain What is the best method for redirection? eg. JavaScript Can this be achieved by adding a single line of code to their main site Can this be done in an SEO friendly way so that the redirection acts like a backlink? Many thanks.
