Can you add keywords into the title tag and/or h1 after indexing or will this trigger a penalty?
On a Wordpress website which is about 3-4 months old, a customer has created several key service pages without putting all of the proper keywords into the title or h1. For example, for an English course, he has a title "learn English for life Company name location" without any mention of the word course. The word course does, however, appear on the page a few times.
If he adds course into the title and / or h1, will this trigger a penalty??
