I want to change all of the title tags on my website by adding a couple of more keywords (not keyword stuffing) but our previous media company chose words that were not aas relevant as ones I found. However I was warned this is a bad idea, it will make traffic drop and if it works we will only see about 5% increase to pages. Please advise. Should I change them and hwo should I do it? One by one slowly while changing content to match or all at once?
