I have a website, and I've build a blog for that website that is located: www.mywebsite.com/blog Will the pages that I will be posting in that blog count as new unique content pages that are updated daily for that website? I know that for google you must update your website with new pages very often. Will it be okay for google to post pages there? Will that make my website bigger with lots of pages?
Yes it does. I have several blogs and the individual pages definitely get counted, but you need to make sure your blog pages have similar keywords to gain maximum benefit from them.
