Price is the first filter and it is rarely shown. Monthly rates with what each tier includes, and whether a contract is required, is searched constantly, and a gym that hides it behind a trial pass loses the comparison silently.
The new year is not a season, it is the season. Search volume multiplies for a few weeks, and pages published in December are the ones that capture it while everybody else is still writing an offer.
Classes reach a different person entirely. Somebody searching for a particular class, a beginners' course or a specific discipline is not shopping for a gym and would never type the word, but they join one to attend.
Hours settle it for many people. Early opening, late closing and weekend times decide whether somebody on shifts or with children at school can use the place at all, and those details outrank the equipment list.
