Plz tell me what are Tags in Wordpress blog ? Why you use tags Assume i have a category Good Morning SMS in wordpress blog, Now when i add good morning sms messages in that category should i have to add good morning tags with each sms post in that category or only add good morning tag with only one sms post ? When anyone will click on good morning tag in tag cloud he will see only posts where i have added good morning tags or will see all good morning sms messages ? Can i add tag in post which didnt have that word in post, for example if i make good morning sms post which didnt have good morning word in whole sms post then can i add good morning tag in that post ? Plz explain Tags for wordpress in details and how to use these, i need complete tag guide, if anyone help i will be very thankfull.
