I examined your site looking for a reason and here is what I think:
- the domain is registered while ago , however there are not many pages indexed, also I
changed the content of the site.
- the blog you have , has very few articles yet - less than 40 , which is since July, which means that there is no content frequently updated. This tells the bots that there is no need to crawl the site so often.
- the content that is present might be duplicated at other place, "more important" from your site
- you may try to add some meta tags , at least description and
