Welcome to the Q&A Forum

Ternit, I would ignore a blog.wordpress.com.  This isn't giving you any natural traffic.  You want the blog on your site. I seem to agree with everyone that your goal should be to focus on optimizing your current website with keyword rich titles, h1s, meta description, and meta tags. If you have any pictures on these pages, I would also look into title tags and alternate title tags. Also if you don't have any social media accounts set up, do this now and make sure that you have plug-ins in place, to make your content is easily shareable.
