I checked out your site at ahrefs.
I see an increased ahrefs rank in avg 3 months (your site went up in about 597,079 positions).
Since about 17 April i see a decreased number in referring pages. You lost about 450 referring pages to your website.
Ahrefs shows me that you have about 179 different websites (not webpages) that have backlinks to your site.
I read somewhere that google started to "punish" sites that use a pop-ups. You have this "Enquire Now for Best Chardham Yatra". Check this info, it might be something that drags your site down.
Your site looks outdated.
There are problems with the mobile version of this site. Google pays much more attention to it that it used in the past. fix it.
