Hello I have a very important question to ask that is. How much keyword can i stuff on Meta Keyword tag? Is there any limitation? Do i have to add Meta Keywords on every page? What all tags should i optimize?
Meta Keyword tags are not very valuable anymore. You should fill them out, and optimize them, but DO NOT keyword stuff them or spend too much time on them. Specific answers to your questions: 1) Just use the main keyword once in the meta tags 2) Yeah, but it should be tailored to the specific post, not the entire page. 3) All of them. You're best bet is to just use a plug-in (assuming you're on wordpress) and let it do the work for you. Michael
