Is there any chance to get rank in first page of Google without backlinks?

If you want first page rank.. you need to have a website people WANT to visit, and do... plain and simple. Unless you do you don't deserve page one rank.

My doubt is one of Competitor website have no worthy backlinks and DA, PA also less compared to the my website. He is appearing top 1st in result Page. I Don't know the reason. that's why am asked that question.

Don't overlook the obvious... web bots scour the sites... people click on those links to your site... if people keep doing it you move up on the page.

What you submittied for your website and how it is worded also is key.. You can get page one without ANY backlinks... and those can be counter productive (back links, because they screw the sites you put them on so they HIGHLY frown upon it).

Its not ONE simple thing.. but multiple things... you can tune, wait a month and see if you go up or down.. tune some more wait another month and see...

I along with a business partner managed to get page one rank on a website using NO backlinks.. paying no placement fees.. based purely on content in about 3 months time from first going live.

Its also possible, your competitor actually has a better website. You can't let pride prevent you from seeing what they might be doing better.

To get rank in the webpage you need to do various off page activities...
Activities such as
Forum posting
Question and answer
Search engine submission
Directory submission
Social bookmarking
Doing these activities their will definitely be achange in your page rank.
