I'm going to be reselling some services from graphic design to SEO to locals and international businesses as well. I'm also going to add a blog to the business website to help with the rankings but also to share my experiences and opinions on marketing etc. Question is, will the website be profitable at a later date if I decide to sell it? Like on flippa etc provided that the blog gets good amount of traffic and readers OR should I create the blog on a subdomain such as "blog.mywebsite.com" I just want to know if it will be profitable as a regular business website with a blog rather than making the blog separate. Thanks.
