Since bolding a keyword within the content of a page can help boost that page a tiny bit in search results, is it okay to bold the keyword everytime it shows up on a page, or is it better to do it just once? I'm not sure how far one can go with that before a search engine may consider it spam. Also, since italics also help with search engine placement, can one bold and italicize the same word to help get it better SEO, or is it better to choose one or the other? Thanks for your help. :)
