Should i get links to my sub-pages also?

i am a bit confused , as i have been doing seo like this all the time , i was making a site and getting links to that website with the keywords i am targetting... but i have read in some posts that i need to get backlinks to the sub-pages also ..

For example if i make a site (using a CMS) with hundreds of pages and i get links with the keywords i am targetting , is this enough? The main page has some content about the keyword i am targetting but the sub-pages also have .. will the sub-pages get neglected?

 

If your subpages are well linked with each other then they wont be neglected. You can create a sitemap and submit it to google etc for better indexing.

If you can manage to get some backlinks for your subpages, it'll be better, but it isn't mandatory.

 

You should, without a doubt, develop links to every page you have optimized.

 

If you can get back links to your internal pages, though difficult, nothing like it.

 

If i have a site with 1000 pages with all aiming same keywords , i should get backlinks to all of them ? I think if i make all the pages linked well , with a sitemap , it is enough.

 

why do you have 1000 pages all targeting the same keyword?
