As an Ad network I'm facing lots of advertisers coming to me, and telling me they want to promote their business and simply get more traffic running on their website and collect leads.
I think there is 2 good ways to do so:
1. If you don't want to deal with creating landers and more, You can just launch a pop campaign and redirect them to your signup page. If the traffic is specified and you know your audience it can work. I have several clients doing so.
2. you can promote an offer and ask people to download it and submit their email.
Do you get clicks from Google search engine for your travel website?
The best way to get customers for kind of this website is getting organic traffic or if you can not do SEO, you can try to buy advertising on websites that related to travel.
first you need to have an email marketing service provider or popularly known as autorespoder. Second you need to have a landing page to get leads. There's a lot of autoresponder and landing page builder you can choose from.
Autorespoder that you might use.
Landing I know that a lot people use and very happy with the service Leadpages.net. By the way there's an autorespoder that have a built in landing page builder on their platform getresponse and convertkit are examples of that.
I personally use convertkit because of its user friendly interface and good deliverability rate when sending emails to your leads.
You can try to create a blog on your website and create relevant articles. Also, you can do some activities in social media - create pages for your website, fill it with content.
Also, you can run ppc campaigns to drive traffic to your website
