More often, we see domain strategies employed to boost organic SEO traffic which leads to us creating multiple landing pages with optimized CTAs (Call To Action) to improve conversions. These sites all have on-page SEO applied so that they’re properly indexed and then a traffic generation program to drive more visitors to these targeted URLs.
It’s very common to build landing pages for Pay Per Click campaigns or for Demand Side Platforms (DSPs) running paid traffic campaigns like Display ads and Video Pre-Roll ads to boost conversions for these efforts instead of driving traffic to the webpages only since we can run A/B tests between both to assess which performs better.
