Short and simple! When you have two identical pages on your website and somehow you have to include both URLs for users, all you have to do is to include the rel canonical tag to the preferred version so that Google finds out that what the original page is and will rank accordingly.
Google will no rank both pages containing the same content but it will still b available for users and search engine will not hurt you for having a duplicate content on the website.
Hope this helps!

The rel="canonical" attribute should be used when there is a set of pages with the same or highly similar content.
This could be for example a category page which lists the products in different orders on different pages with for example URL parameters. (http://www.example.com/products.html?order=popular VS http://www.example.com/products.html?order=newest)It could also be product pages appearing several times at different URL's (http://www.example.com/product1.html AND http://www.example.com/category1/product1.html AND http://www.example.com/brand1/product1.html)
In both of these cases Google would index all versions of the page and duplicate content issues will arise. Duplicate content can really harm your rankings. In situations like this you could use the to indicate to Google that they should index the page listed in the canonical tag and not the one they are currently viewing.

The canonical tag is used to tell search engine crawlers (Googlebot, Bing bot, etc) that the page they are viewing should be indexed using the value of the canonical tag.
Say the bot is crawling http://www.domain.com/page.html?var=1, a canonical there could have "http://www.domain.com/page.html" as the value to tell search engines that http://www.domain.com/page.html is the page they should be indexing.
It does not guarantee that the engine will in fact index that URL, but it helps avoiding duplicate content issues.

Use of subfolders for my casino directory
Been trying to find an answer to this for some time, so I hope someone can lend me a hand.. I've started building out my casino website Nerdybet, which will list regulated gaming vendors within each US state. A part of the idea is to create a high level web directory of legal betting sites. Now, say I want to list all legal casinos within a specific US state. What's the most search engine friendly way to build out the hierarchy? To clarify, this will be the main casino directory page: https://www.nerdybet.com/gambling-sites-directory Based on that, I can now pick either: a) Nerdybet.com/gambling-sites-directory/stateX

Sitemap error is reported when using a sitemap-index generated by Yoast
I've installed the Yoast SEO Plugin for wordpress and I've setup the sitemaps using it. I saw the tool has generated the Sitemap index file http://www.phraseexpander.com/sitemap_index.xml with different indexes for posts and pages I've submitted that to google and it's indexed. When I use Seoquake to check my website, I see that it says that the sitemap is missing (in fact http://www.phraseexpander.com/sitemap.xml) is returning 404. Shall I fix that? Shall I do a 301 redirect in my .htaccess file to http://www.phraseexpander.com/sitemap_index.xml Thanks.

Events in Wordpress Creating Duplicate Content Canonical Issues
Hi, I have a site which uses Event Manager Pro within Wordpress to create Events (as custom post types on my blog. I use it to advertise cookery classes. In a given month I might run one type of class 4 times. The event page I have made for each class is the same and I duplicate it 4 times and just change the dates to promote it. The problem is with over 10 different classes, which are then duplicated up to 4 times each per month. I get loads of duplicate content errors. How can I fix this without redirecting people away from the correct page for the date they are interested in? Is it best just to use a no follow for ALL events and rely on the other parts of my site for SEO? Thanks, T23
