I have been working on a project to build up a website and since the delay for the initial launch of the website were short, I wanted to have some minimal content on the website ASAP  so that the website could have a good ranking in Google when it will launch. The bad part in the story is that I had some page with a lot of Lorem Ipsum online. When I realized that it was a pretty bad idea to have pages with a lot of Lorem Ispum, it was too late. The top keyword that Google had found for my website where nearly all Lorem Ipsum. Now, it's a bit less dramatic since the real keyword I am working toward have gone up, but nonetheless I still have a good percentage of keyword that are Lorem Ipsum.Should I be worried about the situation and what can I do to make those Lorem Ipsum keyword disappear or be less significant ?
How to clean the Lorem Ipsum of my keywords for my site?
