Hi Danijela, I have an ambitious suggestion for you and it's something I'm about to initiate.
Start a podcast and interview as many influencers in your niche. If they have 10,000. followers or more than interview them. Their follower will come to your site to hear their favorite influencer's interview with you.

The benefit to you is free traffic, image ten, or twenty thousand people seeing your offer and subscribing to your mail list.

And you won't even need to write an ebook they will join your mail list just to hear who you're interviewing next.

I have other ideas PM me and we can talk more.

what about a few checklists - with this changing climate for travel people need ot be able to take what is needed and that has changed
so something that poeple can refer to as they are getting ready to make sure they haven't forgotten anything would be useful....
good luck

Hi Danijela, your book could be based on, "The Psychology of Travel". This would be a great combination on what you want to write about and it will relate to your travel niche website.

I agree with Diane. Good luck.

Hi - ideally, you need to write your own e-book to attract subscribers. You need to offer something original that they can't find elsewhere.
