Khansaccounts,

Definitely improve it...

Build more onsite content (diverse content, such as written content, video content, images) around your primary target keywords. Also place outbound links to your other relevant inner pages and to relevant homepages and inner pages of authority sites from time to time...

Use your secondary keywords (diverse combination of generic keywords, branded keywords and commercial keywords that aren't in the title, meta description and tags of your onsite content) as anchors of links pointing to your content pages (diverse combination of inbound links to your homepage and to your relevant inner pages). Build these links on heavily trafficked homepages and inner pages (combination of dofollow and nofollow, more homepage dofollow links, better) of niche-relevant sites, blogs, Web forums and social networks with decent DA and PA...

Share your onsite content across heavily trafficked sites with decent DA and PA (as syndicated content, but a few syndicated copies would be fine) and in relevant social networks (share most of your onsite content in your Facebook page and so on)...

for start its good, get more authority backlinks and do internal linking.

You people are such sheep. Stop following the crowd and think for yourself.

The DA and PA do not matter. Focus on traffic and rankings. DA and PA do not make you money.

OP Why don't you start a SEO campaign for the site?

DA / PA or TF / CF is important but how much is enough for your website depends on your competition as well.

To help increase them, you need to get good quality links. Also be reminded that DA/PA can be easily manipulated. So do some proper research on them.
