hi every one honestly speaking i am new in this field, Here i just want to know that how to improve my website Page rank/ SERP and how can get more traffic on my site.?
Mostly, you will have to remove all the spam (spam posts, spam links) from your site. Make sure your site has good, unique content (as much as possible). There are a few more things you can do to improve your PR as described here: https://forums.digitalpoint.com/threads/how-to-improve-serp.2703790/ (scroll down to the post #5).
On the basis you have attempted to previously build backlinks using grey hat methods, the description above provides strong advice. To second the above, your content needs be contextual and relevant throughout, introducing odd subjects, random posts and details will only deter a strong ranking. When building links aim to gain contextual, relevant links from other sites in a matching / very similar niche. Good luck with the development and welcome to digitalpoint.
Well, you most of the good answers are already given by @qwikad.com and @-bank- but I would also like to add few points here and that is you also need to keep your eyes on the upcoming trend if you want your self to be visible in the eyes of the search engine. Keep updating your content i.e. by the means of blogging share something new to you visitors, in this way they keep looking for you even if your out of the search results. But I don't think that you are going to looses visibility as Google loves fresh content.
couldn't agree more, you have to be as much trendy as it's possible, and it won't hurt to additionally send some social signals about what's new on your site, but I don't mean spamming the hell out, just create fb tweeter etc accounts for your site and every time you post/change something, try to inform about it there also
Check your content and backlinks. Also pay attention to your On-Page (title, description, alt tags for images, title tags for links, H1 tag for your main keyword, H2 for your secondary keywords and good keyword density) and Off-Page (quality backlinks using DIFFERENT methods -> Social Bookmarking sites, forums, blogs, web2.0, directories, etc.) SEO!
