I have an HTML website which is on a subdomain. Under it i've added a directory which consists a Wordpress Blog.

HTML site: he.mydomain.co.il
Blog : he.mydomain.co.il/blog

I would like to get the SEO benefit from the blog to my HTML website.

Is there anything in particular i should do in order to achieve that ?

Is the sitemap of the HTML website should contain the WP blog ? if so how i can do that ?

any tips will be appreciated..

Thanks in advance..
