help for my website which is PR 1 and good traffic?

I think you are so much confused about your site. Your title and comment both are saying different things.

Anyway to better ranking in Google first of you have to do a proper on page optimization to make your website SEO friendly

On page activities includes:

1. Content Optmization
2. Keyword Research
3. Prepare Meta tags
4. Heading Tags
5. Internal Linking
6. Image optimization
7. Check URL structure
8. Add Google Analytics
9. verify your site in Google webmaster Tools
10. Upload Sitemap.xml file
11. Upload Robots.txt file

I think this is enough for on page.

After completion of on page activities try to build some quality backlinks with different off page activities. But remember whatever the link you are generating it should be PR1 and above.

To increase PR you need to maintain the quality of your site. so don't do the unethical SEO only use pure white hat SEO.
