Include Keyword Synonyms in H1 and H2 Tags
I usually use my exact keyword in my page’s H1 and H2 tag. But if I feel that the page is over-optimized, I’ll replace the exact keyword with a synonym instead.
So if my target keyword was “Low Carb Desserts” I’d use a term like “Sugar-Free Desserts” in an H1 or H2 tag.
Simple.
