Google has a help page about this exact issue.

• [*]Google may have indexed your page under a different version of your domain name. For example, if you receive a message that http://example.com is not indexed, make sure that you've also added http://www.example.com to your account (or vice versa), and check the data for that site.
  [*]If your site used to be indexed, but no longer is, you can read more about possible reasons for this.
  [*]If your site is new, it may not be in our index because we haven't had a chance to crawl and index it yet. Read more about how to tell us about your site.

One issue that's not mentioned on Google's help page is a poor internal link structure. You can read more about internal links here:

As I mentioned in my response to your PM, I'm posting what I sent you because I prefer having something to reference when another member inevitably asks why their pages aren't indexed.

To start off, make sure that you've set a canonical version of your site in your Google Search Console account. This page will tell you exactly how to accomplish this.

Once you've done that, ensure that you can only access your site from your canonical URL. For example, if you set http://site.com as your preferred domain, http://www.site.com should redirect to the naked version of your URL.

I can't exactly tell you how you should be building Internal links without seeing your website (I don't have the extra time to look at your site), but if you were using Wordpress, this related posts plugin is an easy solution to that problem. As a general rule, I like to organise all of the sites I manage by placing pages and articles in the appropriate subfolder (e.g., site.com/blog/article. site.com/services/service1).

There's also the issue of low quality pages not being indexed due to either page-level penalties, site-wide penalties, warnings, or algorithmic penalties. While algoithimic penalties don't show up as a penalty in your Google Search Console account, you can rule out the others by checking the manual actions and security issues tabs.

Something I forgot to mention in the PM was crawl issues. If Google can't crawl the page, it won't index it. Check the crawl errors tab in your Search Console account and try to ascertain if and why Google is having trouble crawling your site. Moz has an article that goes over this in more detail. https://moz.com/blog/how-to-fix-crawl-errors-in-google-webmaster-tools
