There are special techniques in order to have your web site appear in the search engines for the appropriate keywords.
For example, just using a large amount of keywords in the meta tags
for the web site will not necessary result in better placement for those
keywords. Especially if the website content is not considered relevant
this might yield negative results and affect your web site ranking.
Above all, you should strive to enter only keywords that are absolutely relevant to the content provided on the web pages.
