How To Stay Off Of Google's Radar
The final alternative method is the most expensive but gives you quite a bit of flexibility. You can use a service like Leadpages.net. If you are not familiar with Leadpages, they are a third party service where you can create very professional looking sales pages and choose where you want to host them. To stay off of Google's radar when creating a page through leadpages, you will want to use the page directly from their site.
They also have a blank template so if you wanted to create a review page for your PPC campaign that doesn't look too sales-like, that can be accomplished as well.
Leadpages does give you the ability to download the generated code and then incorporate it into your website. Further, they have a WordPress plugin where you can incorporate the generated page from within your Dashboard. But for this strategy you won't be using that. You will simply use the URL that they provide. It is hosted on their site and that is the benefit of this method.
The downside to this approach is it costs $37 per month to be a standard member of Leadpages. You can save some if you choose the yearly plan.
This is the most costly method to implement. One feature that they recently added is the ability to split test pages but this is for premium members only and the cost for that is obviously higher.
