Welcome! Here is some feedback, questions, comments, etc. for you. Hope this helps:
1. your main site needs more seo and/or evergreen content on it. It looks like everything there is a review or promotion, but there is no static content that you’re using to target specific keywords.
2. You should get a navbar on your site – looks like all of your internal pages are accessible from the footer only
3. After you do the above, use better H1 tags. Here is a resource for you
4. The e-cigarette banners seem a little out of place. Do you have data supporting the cross-over between gambling and e-cig?
5. You should be collecting e-mails as much as possible. This will help you to build a database that you can remarket to rather than relying on only those who visit your site
