Know-How Exchange : SEO/SEM

Make sure you have lots of high-quality relevant links to each page you want Google to see. You might even want to have Adwords campaigns for each page too.

Remember that Google wants searchers to find what they're looking for, so you want to have a significant presence for each search term, and you want good message-match for each keyword, descriptive/ad copy and landing page.

Make the contents relevant and salient ... BUT, it's a mistake to put machines ahead of the needs of people.

Google posts some information pages, this is from one of them:
"Google is a fully automated search engine that uses software known as 'web crawlers' that explore the web on a regular basis to find sites to add to our index. In fact, the vast majority of sites listed in our results aren't manually submitted for inclusion, but found and added automatically when our bots crawl the web."

Here's more:
"Although Google crawls billions of pages, it's inevitable that some sites will be missed. When our spiders miss a site, it's frequently for one of the following reasons:

The site isn't well connected from other sites on the web.
You've just launched a new site and Google hasn't had time to crawl it yet.
The design of the site makes it difficult for Google to crawl its content effectively.
Google received an error when trying to crawl your site."

Add all the Pages you want Google to see i.e. Index in Sitemap. Add the XML sitemap in the root folder of your website and verify it by visiting domainname/sitemap.xml
Also, Add Sitemap in Google Search Console (Google Webmaster Tool)
Add sitemap URL in a robots.txt file which will be placed in the root folder of the website.

These two things will help you to provide all your website URLs to Google.
