if your site doesn't have much pages, do a Sitemap and google will easily find everything, if you have hundred of thousand of pages it will take a while before google indexes your site fully

Google crawling is the action that Googlebot does on your site: it's goes from page to page following links on those pages. There are no "links that must be included". Your internal linking structure is entirely up to you and it should be driven by your SEO strategy.

As a rule of thumb, you want every page on your site to have at least 1, but better 2 links pointing to it. This is to ensure that Googlebot will find each page and has the chance to index it.

Another thing that you will want to do is to submit your sitemap.xml to Google in your Webmasters account.

The only way Google can find a page in your website is if there is a link to it. weather externally internally or from a submitted sitemap. Generally the more links you have the more Google will find your site and see the links and give it some authority.

Just make sure the links you are getting are good quality, not spam and targeted properly.
