Basically I am asking is whether Google et al are going to treat my webpages developed through wordpress in the same way as they would treat other websites with a *.com? Also, as far as SEO goes do I have to jump through some additional hoops if I am working with a wordpress site ? Would I have any advantages instead ? 
Is it better in terms of SEO if I develop my Website meant for marketing my service on a regular .com domain compared to a wordpress site?
