Hi consumption of Traffic. Suggestion Pls…

I’m running my webpage with 5GB of hosting and 10GB of traffic and recently my visitors jumped to 5000 unique visitor a day. then it was not enough and i paid more for 25 GB traffic.

Now it’s coming to 30GB and i cannot understand it. There is no video except youtube, flicker etc. which i don’t host.

I don’t publish pdf files to be downloaded.

Is that number and traffic reasonable or there might be any other problem related to hotlinking.

– I disabled hotlinking by htaccess.
– I’m using CLOUDFLARE CDN with Rocket Optimization which make my webpage ever faster.

Thanks for your comments and suggestions
