Multiple Home Page url'S and Redundant Host Names 
Автор: Giulio V.Google Analytics informs me of these two issues
"Multiple Home Page URL'S and Redundant Host Names"
This has been going on for a long time and I'm getting concerned this could be a problem of Duplicate Content that may be hurting my SEO.
Also on another website analysis test by Neil Patel it tells me the similar situation.
2 PAGES WITH DUPLICATE META DESCRIPTIONS - Distributor of Auto Body Repair Equipment and Aluminum repair equipment for the repair of collision damaged vehicles. Established since 2002 https://prolinesystems.net/ https://prolinesystems.net/index.html
2 PAGESWITH DUPLICATE <TITLE> TAGS PAGE URLTITLE2 pages Body Shop Equipment - Body Shop Equipment https://prolinesystems.net/index.html https://prolinesystems.net/
I have had this issue for quit some time, when I look at my Site Map I do not see anything I can change.
Why are there two versions showing up? And how did this happen?
https://prolinesystems.net/index.html and https://prolinesystems.net/
So, How and Where do I go to correct this?
Thank you for your support. Giulio
This happens because Google looks at your domain and your index.html separately and sees them as different pages. To get around this, you can enter <link rel = "canonical" href = "https://www.yourdomain.com ″ /> in your index.html so that there are no differences between the domain and the index.html. You write the code in the properties of the page in the area before the </head> tag.

Hi Franz,
Thank you for your reply. Where exactly is the Index of my site and what about two versions of my site showing as www.prolinesystems.net and http://prolinesystems.net? How do I fix this.
So maybe if you could be so kind as to provide step by step instructions, would be very much appreciated.
I am not as advanced as some of you folks and my fear is than I may do something wrong.
The index.html page is the start page of the project. In "3 Sitemap" it is the page with the little house. There you choose Page Properties and then the option Advanced. You enter the code in the area before the </head> tag.
You fix the two versions of your Website as follows:
There may be a setting in your provider account where you can check the box for "force https"!
If your provider does not have the option to force the redirection to the https page, you have to create a .htaccess file yourself. To do this, use the Windows editor to create a file with the following content:
RewriteEngine On
RewriteCond %{HTTPS}! = On
RewriteRule ^ https: //% {HTTP_HOST}% {REQUEST_URI} [L, R = 301]
These save, for example, as htaccess.txt. Then rename it to .htaccess (yes, the point must be in front) and load it into your server directory (where you also upload your homepage). This means that every call to your site is automatically directed to the https site.
