Hello again. Thanks again for the panel on answering SEO questions.
If you rank for a particular long tail keyword on a particular post, what are the SEO penalties, if any for adding or changing the words of other posts to accommodate those keywords?
Of course, those words should be relevant. Therefore, if one or two words do not fit, then it will not be added. What I mean is adding or changing words without radically changing the main idea of the post.
