Keeping up with your keyword density is very important because it is the numbers of times you see a certain word appear on a web page. Only use your keywords though where they are needed, because you don’t want to overdo it, or it will be denied and be considered spam.
In today’s virtual world the spam or unwished-for messages is a genuine issue. It seems the spammers are using autoresponders to do their dirty work. This is bad for everyone who uses an autoresponder with good objectives. Their messages are often understood as spam making the owner wonder what’s wrong at times. Sometimes a user may also wonder why their messages are blocked or reported as spam.
