Excited levels in ${}^{111-121}\mathrm{Ag}$, odd-$A$ isotopes populated following spontaneous fission of ${}^{252}\mathrm{Cf}$ have been studied using high-fold $\gamma$ coincidences measured with Gammasphere array of Compton-suppressed Ge spectrometers at Argonne National Laboratory. The experimental information on these nuclei reported before has been corrected and extended. In the work we discuss the evolution of triaxiality in odd-Ag nuclei. Relative positions of the $\pi p_{1/2}$ and $\pi g_{9/2}$ shells defining the $Z=40$ gap when approaching the $N=82$ closure, the $\pi 1/2^{+}\left[431\right]$ intruder bands, the three-quasiparticle configurations, and the so called $j-1$ anomaly in odd-Ag nuclei are also discussed.
