Hi, I going to promote 2 completely different services on adwords. I have a dilemma: 1. Put both landing pages (mini-sites) on the same top domain as subdomains. 2. Create 2 different sites on different domains. Can adwords dislike the option of 2 different services on subdomains with same master domain - both in the same adwords account? Can this lower my general quality score? I hope someone can help me understand this. Thanks
About quality score.... it is depends upon no of factors. Also take care of this factors. You can check here about quality score https://support.google.com/adwords/answer/140351?hl=en About whether you should go with landing page with subdomain or with different domain, its up to you. If your site theme is same then I suggest put it as in same domain.
