I currently have text articles about various topics on my site - for this example say I have written about "Negative Reinforcement". This article is live over a month now and getting listed on the first google page with an added keyword which the article is specifically related to.
Now I want to create an infographic related to the same topic "Negative Reinforcement" - but I want to call the page this infographic will go on "Negative Reinforcement Infographic" while the article is currently called just "Negative Reinforcement".
Neither page will have duplicate content from each other. The article is 2,000+ words so I don't want to throw more into it by adding on the infographic and I want to specifically create the infographic as linkbait and on a stand alone page.
I am curious if adding another page with such a similar title and H1 have any negative effect ("dilute" the strength of the other article), for example will google take having two different pages with such a similar heading as potential keyword stuffing and penalise the site?
