1. Star Generator: It generates a big list of urls with stars in between. This can help you get a decent amount of traffic for a website but at a much cheaper price on Leadimpact.
2. Domain Variation: Similar to the star generator, this generates a list of Domain Variations on which you can bid to get cheaper traffic. As Leadimpact's matching criteria is based on 'string' match, it doesn't understand whether you are bidding for a domain or not.
3. Preview URL: You can use it to see how your Landing page will look in a Leadimpact pop-up browser. For this, I used other tools earlier but it showed a pop-up for 800*600 resolution whereas most of the Leadimpact pop-ups have a viewable area of 775*450. So, I made it accordingly.
Let me know how it works for you!
