SEO - 2 websites in the same domain

Question

I have my domain (http://www.foobar.com, for example) and my website talks about technology. I want to have another website (with other content, not about technology) inside of it (http://www.foobar.com/loremipsum). I can find http://www.foobar.com in Google Search, but http://www.foobar.com/loremipsum no ... What should I do to index this website? Thank you.

update

My main site (http://www.foobar.com/, a WordPress installation) has an .httaccess:

# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>

# END WordPress

Does it affect the index of http://www.foobar.com/loremipsum ? Thank you.

Answer 1

1) Submit the main page to Google directly

2) Submit an XML sitemap

3) Link to those inner pages from anywhere. The main website or any other external website will do.

FYI, ideally you'll get a second domain name for that website. It will give you more SEO opportunities and make it clearer to users that these are two separate websites.

update

That will have no effect on the indexing of those pages
