As well as the other suggestions above, if you take a look at the waterfall on GTMetrix, WebPageTest and Pingdom, they show two other issues:
1. Your server is slow to respond (the time for the first byte of data). This ranges between 1-5 sec. Not satisfactory. I would do some testing with a default theme loaded (e.g. Twenty-Fifteen), and also try testing with the P3 Profiler to see if any plugins are resource heavy. If you can optimise your site as suggested above and rule out any theme or plugin placing a heavy load on the server, then you would have a strong case to take up with your host (who might offer to move the site to a different server (good sign), or suggest that you pay more to upgrade your hosting package (bad sign)).
2. You seem to have 2 slow calls to gosocial.in/call/medianet/ I can’t see any obvious advertising on your page. Perhaps you could try deactivating the plugins to see which one is making these calls.
Good luck!
