I run a jewelry website which gets fairly consistent conversions of 1-1.5% out of about 10k visitors per month. The last few weeks, however, our conversions have dropped to closer to 0.3-0.5%. No major changes have been made to the website, no change in traffic/traffic source; is this normal? Any idea what could've caused the sudden drop in conversions? Any help or suggestions would be greatly appreciated.
