Switching from Http to Https, but what about images and image link juice?
-
Hi Ya'll.
I'm transitioning our http version website to https. Important question:
Do images have to have 301 redirects? If so, how and where?
Please send me a link or explain best practices.
Best,
Shawn

Shawn124, whenever you move from HTTP to HTTPs, you'll need to set up the 301 permanent redirects for pages on the site only. The other elements, such as images, JavaScript (if they're external files), and .CSS files will need to be changed only in the code so that they reference the new HTTPs URLs, and not HTTP.
If you load an HTTP element (such as an image that uses the full URL in it's reference rather than the image filename only) on an HTTPs URL, then the browser will give you an error. So generally you need to do two things:
-
set up 301 Permanent Redirect for the page URLs.
-
search the entire website for all references to HTTP and change them to HTTPs (unless you're linking out to an external site).
If the site is in WordPress, you can use the Search and Replace plugin to replace it all at once in the database.

If you 301 redirect all HTTP URLs to HTTPS On the origin server,
To Move the origin server the HTTP to HTTPS On the origin server your redirects on your images will follow
#1
NGINX
Add the following to your Nginx config.
server { listen 80; server_name domain.com www.domain.com; return 301 https://domain.com$request_uri; }
Apache
Add the following to your
.htaccess
file.RewriteEngine On RewriteCond %{HTTPS} off RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI} [R=301,L]
(TOOL Apache htaccess to NGINX config tool https://winginx.com/en/htaccess)
#2
Search and replace the old HTTP:// URLs to New HTTPS://
http://mydomain.com
tohttps://mydomain.com
http://www.mydomain.com
tohttps://www.mydomain.com
Use CLI or https://interconnectit.com/products/search-and-replace-for-wordpress-databases/
#3
Alert Google that you are migrating to HTTPS https://www.google.com/webmasters/tools/home?hl=en
You will have no issue with your images.
Your link juice will flow as it did before because Google is no longer penalizing multiple redirects (So they SAY BUT don't over use redirects) keep them to a minimum, please.

https://www.deepcrawl.com/knowledge/best-practice/https-dilemma-security-seo/
#4
If on WordPress using proxy or just have insecure content use
Really Simple SSL: https://wordpress.org/plugins/really-simple-ssl/
Your insecure content is fixed by replacing all HTTP:// URLs with HTTPS://, except links to other external domains. Everything is done dynamically.
If using a Photos on a WAF or Pull CDN Force HTTPS
Connections#5
For example, if you're using a CloudFlare for Photos? You would use page rules to force a 301 redirect HTTPS
https://tools.keycdn.com/curl see #9 in https://www.maxcdn.com/one/tutorial/edge-rules-recipes/
#6
301's will not lose link juice see:

Test using https://www.deepcrawl.com/ & or https://www.screamingfrog.co.uk/seo-spider/

"Making the switch from HTTP to HTTPS
- Start with a test server. This is important because it lets you get everything right and test without screwing it up in real time. Even if you are doing the switch without a test server, there’s almost nothing you can do that you can’t recover from, but it’s still best practice to have a plan and have everything tested ahead of time.
- Crawl the current website so that you know the current state of the site and for comparison purposes.
- Read any documentation regarding your server or CDN for HTTPS. I run into lots of fun CDN issues, but it can also be straightforward.
- Get a security certificate and install on the server. This will vary depending on your hosting environment and server setup too much for me to go into details, but the process is usually well-documented.
- Update references in content. This can usually be done with a search-and-replace in the database. You’ll want to update all references to internal links to use HTTPS or relative paths.
- Update references in templates. Again, depending on how you deploy, this might be done with Git or simply Notepad++, but you’ll want to make sure references to scripts, images, links and so on are either using HTTPS or relative paths.
- Update canonical tags. Most CMS systems will take care of this for you when you make the switch, but double-check, because that’s not always the case.
- **Update hreflang tags **if your website uses them, or any other tags such as OG tags for that matter. Again, most CMS systems will take care of this, but it’s best to QA it just in case.
- Update any plugins/modules/add-ons to make sure nothing breaks and that nothing contains insecure content. I commonly see internal site search and forms missed.
- CMS-specific settings may need to be changed. For major CMS systems, these are usually well-documented in migration guides.
- Crawl the site to make sure you didn’t miss any links and nothing is broken. You can export any insecure content in one of the Screaming Frog reports if this is the crawler you are using.
- Make sure any external scripts that are called support HTTPS.
- Force HTTPS with redirects. This will depend on your server and configuration but is well-documented for Apache, Nginx, and IIS.
- Update old redirects currently in place (and while you’re at it, take back your lost links from redirects that haven’t been done over the years). I mentioned during the Q&A portion of the Technical SEO Panel at SMX West that I’ve never had a site drop in rankings or traffic when switching to HTTPS, and a lot of people questioned me on this. Due diligence on redirects and redirect, chains are likely the difference, as this is what I see messed up the most when troubleshooting migrations.
- Crawl the old URLs for any broken redirects or any redirect chains, which you can find in a report with Screaming Frog.
- **Update sitemaps **to use HTTPS versions of the URLs.
- **Update your robots.txt file **to include your new sitemap.
- Enable HSTS. This tells the browser always to use HTTPS, which eliminates a server-side check and makes your website load faster. This can also cause confusion at times, since the redirect will show as 307. It could have a 301 or a 302 behind it, though, and you may need to clear your browser cache to see which.
- Enable OCSP stapling. This enables a server to check if a security certificate is revoked instead of a browser, which keeps the browser from having to download or cross-reference with the issuing certificate authority.
- Add HTTP/2 support.
- Add the HTTPS version of your site to all the search engine versions of webmaster tools that you use and load the new sitemap with HTTPS to them. This is important, as I’ve seen traffic drops misdiagnosed because they saw the traffic in the HTTP profile drop, when the traffic in reality moved to the HTTPS profile. Another note for this is that you do not need to use the Change of Address Tool when switching from HTTP to HTTPS.
- Update your disavow file if you had one for the HTTPS version.
- Update your URL parameter settings if you had these configured.
- Go live!
- In your analytics platform, make sure you update the default URL if one is required to ensure that you are tracking HTTPS properly, and add notes about the change so that you know when it occurred for future reference.
- Update your social share counts. There’s a lot of gotchas to this, in that some of the networks will transfer the counts through their APIs, while others will not. There are already guides for this around if you are interested in keeping your share counts.
- Update any paid media, email or marketing automation campaigns to use the HTTPS versions of the URLs.
- Update any other tools such as A/B testing software, heat maps and keyword tracking to use the HTTPS versions of the URLs.
- Monitor everything during the migration and check, double-check and triple-check to make sure everything is going smoothly. There are so many places where things can go wrong, and it seems like there are usually several issues that come up in any switch to HTTPS.
One question I’m often asked is if incoming links should be cleaned up. This is a tremendous amount of outreach and effort. If you have time, then sure; but most likely you’re busy with other things, and I don’t feel it’s necessary. However, you should update the links on any properties that you control, such as social profiles."

Unless you have to modify whatever system it is powering them, do you have a CDN? Or using something like AWS S3?
If so your images should move with the rest of the site. If you're posting them on a content delivery network or an AWS S3 whatever it is you must redirect that as well.

juice will not be lost long is you tell Google your moving the site see the URL below for how to redirect
Some of the systems will have buttons where you'd just click HTTPS others will require you to put the code into the system. I have posted the code below for Nginx as well as Apache.
Redirect from HTTP to https
This last bit will help you tremendously when you’ve not updated every single link on your site yet. You can just add a straight server level redirect from HTTP to https. In NGINX, we do this by having two servers defined in our config, the “right” one; that listens on port 443 and a simple one that listens on port 80 (standard HTTP) and has just this:
server {
listen 80;
server_name yoursite.com www.yoursite.com;
return 301 https://yoursite.com$request_uri;
}This seems to be the fastest way of doing this in NGINX, in Apache you’d do something like this:
RewriteEngine On
RewriteCond %{HTTPS} off
RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI} [R=301,L]- Tools

How to force SSL with. htaccess
If you want to force your entire website to go through https, you can add these rules to your .htaccess file:
| |
RewriteEngineOnRewriteCond%{SERVER_PORT}80RewriteRule^(.*)$https://yourdomain.com/$1 [R,L]
|
If your site is in a subfolder, use this code:
| |
RewriteEngineOnRewriteCond%{SERVER_PORT}80RewriteCond%{REQUEST_URI}folderRewriteRule^(.*)$https://yourdomain.com/folder/$1 [R,L]
|
Only replace yourdomain.com with your actual domain name.

If I nofollow outbound external links to minimize link juice loss > is it a good/bad thing?
OK, imagine you have a blog, and you want to make each blog post authoritative so you link out to authority relevant websites for reference. In this case it is two external links per blog post, one to an authority website for reference and one to flickr for photo credit. And one internal link to another part of the website like the buy-now page or a related internal blog post. Now tell me if this is a good or bad idea. What if you nofollow the external links and leave the internal link untouched so all internal links are dofollow. The thinking is this minimizes loss of link juice from external links and keeps it flowing through internal links to pages within the website. Would it be a good idea to lay off the nofollow tag and leave all as do follow? or would this be a good way to link out to authority sites but keep the link juice internal? Your thoughts are welcome. Thanks.

Will I lose Link Juice when implementing a Reverse Proxy?
My company is looking at consolidating 5 websites that it has running on magento, wordpress, drupal and a few other platforms on to the same domain. Currently they're all on subdomains but we'd like to consolidate the subdomains to folders for UX and SEO potential. Currently they look like this: shop.example.com blog.example.com uk.example.com us.example.com After the reverse proxy they'll look like this: example.com/uk/ example.com/us/ example.com/us/shop example.com/us/blog I'm curious to know how much link juice will be lost in this switch. I've read a lot about site migration (especially the Moz example). A lot of these guides/case studies just mention using a bunch of 301's but it seems they'd probably be using reveres proxies as well. My questions are: Is a reverse proxy equal to or worse/better than a 301? Should I combine reverse proxy with a 301 or rel canonical tag? When implementing a reverse proxy will I lose link juice = ranking? Thanks so much! Jacob

Null Alt Image Tags vs Missing Alt Image Tags
Hi, Would it be better for organic search to have a null alt image tag programatically added to thousands of images without alt image tags or just leave them as is. The option of adding tailored alt image tags to thousands of images is not possible. Is having sitewide alt image tags really important to organic search overall or what? Right now, probably 10% of the sites images have alt img tags. A huge number of those images are pages that aren Thanks!

Website Redesign, 301 Redirects, and Link Juice
I want to change my client’s ecommerce site to Shopify. The only problem is that Shopify doesn’t let you customize domains. I plan to: keep each page’s content exactly the same keep the same domain name 301 redirect all of the pages to their new url The ONLY thing that will change is each page’s url. Again, each page will have the exact same content. The only source of traffic to this site is via Google organic search and sales depend on the traffic. There are about 10 pages that have excellent link juice, 20 pages that have medium link juice, and the rest is small link juice. Many of our links that have significant link juice are on message boards written by people that like our product. I plan to change these urls and 301 redirect them to their new urls. I’ve read tons of pages online about this topic. Some people that say it won’t effect link juice at all, some say it will might effect link juice temporarily, and others are uncertain. Most answers tend to be “You should be good. You might lose some traffic temporarily. You might want to switch some of your urls to the new structure to see how it affects it first.” Here’s my question: 1) Has anyone ever done changed a url structure for an existing website with link juice? What were your results and do you have a definitive answer on the topic? 2) How much link juice (if any) will be lost if I keep all of the exact content the same but only change each page’s url? 3) If link juice is temporarily lost and then regained, how long will it be temporarily lost? 1 week? 1 month? 6 months? Thanks.

Switching from .co to com?
I have a site that does pretty well on a .co domain, but would like to switch to over .com (we own the .com already). If we were to transfer .com and 301 redirect all the .co pages over to their .com version, would we suffer at all? What would you guys recommend?

Do 404 Pages from Broken Links Still Pass Link Equity?
Hi everyone, I've searched the Q&A section, and also Google, for about the past hour and couldn't find a clear answer on this. When inbound links point to a page that no longer exists, thus producing a 404 Error Page, is link equity/domain authority lost? We are migrating a large eCommerce website and have hundreds of pages with little to no traffic that have legacy 301 redirects pointing to their URLs. I'm trying to decide how necessary it is to keep these redirects. I'm not concerned about the page authority of the pages with little traffic...I'm concerned about overall domain authority of the site since that certainly plays a role in how the site ranks overall in Google (especially pages with no links pointing to them...perfect example is Amazon...thousands of pages with no external links that rank #1 in Google for their product name). Anyone have a clear answer? Thanks!

Image Maps
Hey forum, I'm curious about Image Maps. Few things I'm not sure about: 1. Will the links be followed? If so, will Google respect rel="nofollow"? 2. Will the image be considered 1 image? (indexed as image, etc.) Or will each map segment be treated as a separate image? 3. Any other SEO pros\cons to consider when adding an image map to an existing page? Thanks, Corwin.
