As i observed in many blog, after panda and penguin updates some people are still writing primary keywords in bold. Is that really helping? Please tell me.
This is not matter. Your SEO work should be good. for example if you are doing link building then take link at those sites which are relevant to you and having proper domain name, having good back links etc.
Irrelevant words should not be made bold. On the other hand, if relevant keywords are made bold and user experience is good, your page will definitely rank.
no need to bold the keyword but its is good. plz make submission on high pr site and reputed site...................................
This is not matter and no need to bold. google want only quality work and relevant links. content should be unique and updated.
