Hi,

My website is based on android apps and I write only original content there on a regular basis. I want to publicize the good work. So, I thought I will put links in the comments of other similar websites directing users to my website. I don't mean to overdo it. I will use it selectively only for good posts of my website, and will give links in the comments of other 5-6 websites.

I intend to do this by giving very short description of what url is about and the url itself, in the comments of other websites I've handpicked.

So, my Question is: Whether I should give a plain url of my website (which will show my website's name and full address of the post)? Or I should use url shorteners like bit/ly or any other?

I would like to know whether any one of the above will affect Google's understanding of my website in a negative way.

I hope I have clarified my view. Please let me know if you need more details.
