“Well, that is the way as to how SEO actually is preformed, once your website is to the top spot, you can go for and make any changes to content what so ever.”
Ah, no. With Respect, but that is
not the way SEO is performed. You have to optimize it, yes, but if you turn a site into search engine fodder, you are going to lose any and all clients or prospective clients because they would not want to be associated with someone that is clearly out there only to manipulate search engines.

That can also have a really bad impact on your online reputation because if people can openly see that you are trying to manipulate search engines, what's stopping you from doing it in your own business? Even if you weren't responsible for optimizing it in the first place.
When you optimize a website, its to make sure its found in a search performed by prospective clients, and search engines alike. It
has to be optimized primarily for visitors. Making sure that any content can be easily read and is not just one string of keywords one after the other, or even worse, leave a visitor wondering what language the site is written in and trying to load it into google translate to figure out wtheck is going on with it.
If anyone follows that method of optimization, you have my innate sympathies, because all that is going to do is kill your site (oh yes, Google in particular will ice your site faster than you can blink), but any prospective clients will simply go to your competitors, and that is
if they can still find your site once google's gotten hold of it.
