No. You're describing keyword stuffing with extra steps.

Here's what actually happens: headers exist to map the document for a reader skimming and for a parser building an outline. When all six H2s contain the same phrase, you've destroyed the map — every signpost points the same direction, which is the same as no signpost.

Google reads headers as structural context, weighing the words there slightly because they summarize the section beneath. Slightly. Not as a tally of how many times the phrase appears in elements.

The section that ranks for a long-tail query usually does so because one H2 happened to phrase the exact question a searcher typed — variation, not repetition, is what earns the passage-level matches.

Write headers a human would actually use to find their place. The repetition you're proud of reads as desperation to a parser.

(If your outline is unreadable with the keyword removed, it was never an outline.)
