Any shortcuts??

Is there is any simple methods to get more clicks to the website though the site is at 3rd page of SERP result?

Look into conversion rate optimisation. Play around with the title and description of your page to create something that piques the interest of the searcher.

As Zwielicht said, improving your page title and meta description can potentially increase your CTR.

Drive traffic to it. Social Media, Forums, Q&A sites, Advertising, even blog commenting. Just get the word out there and direct people to your site.

1. Speed your site
2. PageSpeed Insights - your site needs to score well on a technical level
3. Click throughs - when people see your result in Google, it needs to get clicked
4. Content - Google needs to see quality, authorative content
5. Inbound links - other quality/respected/high ranking sites need to link to your content
6. H1 on page or next relevant keyword
