Last semester, I decided to stop guessing about SEO and actually measure what worked. My blog about sustainable campus living was getting visitors, but inconsistently.
The experiment setup
I wrote eighteen articles over twelve weeks, each targeting different keyword approaches. Six articles used keywords every sixth sentence. Six placed them every twelfth sentence. The final six focused on semantic variations instead of exact repeats. I tracked rankings weekly using a free position checker and logged organic visits in a spreadsheet.
What the numbers showed
Articles with keywords every sixth sentence ranked faster initially, hitting page two within eight days. But they plateaued there. The every-twelfth-sentence group took nineteen days to appear but climbed steadily to page one over six weeks. The semantic variation articles performed best overall, with four reaching top five positions by week eleven.
The pattern I noticed
Search engines seemed to reward articles where I explained concepts thoroughly using different phrasing. My post on composting used the exact phrase campus composting twice but included related terms like food waste reduction, organic recycling bins, and dormitory sustainability eleven times. It outranked my earlier piece that repeated the target phrase eight times in similar length.
Now I write for understanding first. I mention my main topic naturally in the opening and conclusion, then spend the middle section exploring related ideas that someone searching that topic would want to know. My average time-on-page increased from one minute to three, and monthly organic visits went from thirty-eight to two hundred and sixteen.
