what do you recon guys, what is the best way to set up a blog? as a part of your website or as a separate website on a separate domain? so www.domain.com/blog vs www.anotherdomain.com
If it is related to your website and you need content to improve the rankings of your main site then site(.)com/blog is a good option. Also, it'll b easy to promote the blog this way when compared to setting up a new site. But, if the blog content is not related then obviously you need to setup it at a new domain and promote it accordingly.
