Most Content Management Systems (CMS's) will keep you out of the search engines. It's as simple as that.
Site-Ezy creates pages which are "search engine friendly". The page URLs dynamically assigned to Site-Ezy's pages are readable by the search engine spiders (or robots). Other CMSs generate URLs which the spiders can't read, so normally only your Home page is recognised. This means all the valuable content on your other pages is ignored, dramatically decreases your ranking. And with approximately 80% of all web traffic coming via search engines, a low ranking means lost revenue.
Site-Ezy really can be the difference between a page 1 ranking and a page 101 ranking.
