There are lots of different ways to increase your website traffic. The first way to increase traffic would be to start A/B testing with creatives to see which designs perform better. You can then continue to improve and tweak the highest converting ad sets throughout the campaign.
The second way to increase traffic to your website would be to increase the CPM price of each ad set, as this opens up your ad sets to higher converting ad formats. If you have tight geo-targeting preferences, including a few more countries can help to increase daily traffic.
The most obvious way to increase your incoming traffic would be to increase your daily budget, so you can increase your exposure across multiple platforms.
