When deciding whether or not to have a blog on a subdomain, it is important to consider the following:
1. Do you have the resources and bandwidth to maintain a separate blog for each domain? If so, then having a blog on a subdomain is likely the best option.
2. Will your readers be able to find your blog if it’s hosted on a subdomain? If not, then you may want to consider hosting your blog on a domain that is also hosted by your hosting company.
3. Will you be able to rank higher in search engine results if your blog is hosted on a domain rather than a subdomain? This will depend on your Target market and the keywords that are associated with your niche.
4. Is having your own domain more important to you than ranking higher in search engine results? If so, then hosting your blog on your own domain is likely the best option.
