The tourism niche is quite hard to handle nowadays, I am also working on my own website of this kind, if you would like to talk more please let me know. Just some tips, start making guest posts on relative websites/blogs with dofollow backlinks, as many as you can, promoting your Tour Packages, I am sure that if you work on it, leads will start showing, just need to give it time.
You Need a website make more Attractive First of all your Header not give best Impression and second you use the Simple Colour you need combine colour and third one is that you need change the Banner with you logo then You feel your site Perfect every point of view then try directing some traffic for increase the website back links..
First, what is your sales process? Do you call or email back someone who has submitted a tour query? If so, change the form to better suit that process. I would remove the top section of the form, add an optional 'tour requirements' box, and have the form content say 'Let us call you'. A/B test that with your current form to see how it converts. This type of form has worked really well for a lot of my client websites in terms of generating leads.
Your site is very nice, but i think you do something changes in that. To make a LOGO as per your business site. Please add flouter image when cursor move on header. Please make home page with small detail regarding tour package and also offer any lowest special package any destination. Please add light color instead of existing color. You also add image about destination where any one click to it. Example when I saw about Goa Tour there is no anyone image about beach. And also make it look attractive and advance technology, so someone to like this. All the best.
I think your site could use a redesign of the logo, a better background, better menu, and a re-design of the colors. The layout is there, but needs to be fine tuned.
