I found a website this AM and when I checked the source there were 2 sets of keywords. Also, there were more than 7 in use at each line. They are number one listed in their category on Google. If this is acceptable and the spiders soak up all what's to prevent people from putting more lines down to enhance their Google position?
Thanks, Giddyup

Only one set of keywords in a website source and these are limited in a website. if there is no limit in a website then google not accept it.

That certainly makes sense to me. So, how do they wind up listed in the top slot. Does the spider do the top one and ignore the second?

keywords must relate to site text
keyword farms, get blacklisted from se results
