Hello is there a software that will allow you to design a perfect landing page that give you the best quality score that you pay the least amount of money in Adwords cost. I was told that there is.
You were probably told about XSitePro. However, don't expect to push a few buttons and be provided with a site that gets a high quality score. No software does that. You still have to design the site and construct the Adwords campaign. In other words, only by your own actions can you expect to secure that high score. The software will not do it for you. Don't look for the easy road. There isn't one.
Ive heard decent things about LPgen, honestly it'd be best to come up with a landing page template you can use for each landing page you need. Then you can just change the content/keywords/images/etc... everytime you need a different page. I just did a post on landing page guidelines, and will do a series of 10 posts on perfecting a landing page ... check out my blog
