I used Google's search results feature to find the number of community posts that include the name of girls groups in their title. I set the following search parameter (site:[site URL] intitle:[hangul name of girl group]) for each group.
According to the results for one month, the groups with the most post titles mentioning their name are in this order:
1. Brave Girls
2. ITZY
3. Aespa
4. TWICE
5. Oh My Girl
6. Black Pink
7. STAYC
As expected Brave Girls comes way ahead, especially with the general public. In fangirl dominated communities Aespa and ITZY come on top. Due to a prolonged hiatus Black Pink is the least mentioned compared to the other Big 3. And it's expected for STAYC to come last (nugu company, rookies) but they aren't that far behind Oh My Girl in the total, with more interest in for them in Instiz.
