If you mean 'is your profile a blog' I would say 'no' HubPages is not a 'blog' as such. It is a Publishing site. For you to 'publish' something you will need to 'start a new hub' and write something on a topic, maybe your books and then 'publish' your hub.
Google will then index your Hub and hopefully people searching on their Google search engine will find your Hub and pay you a visit. You should also 'share' your Hubs with other sites like Twitter and Facebook. This will attract more visitors :-)
