Add a USB mic

Some users on Zoom, Skype, and other online meeting platforms are often asked to repeat themselves and have to turn to directly face the laptop to be heard. Business users often set up a laptop with the Zoom call and a connected monitor to view web pages or files during the meeting. But, in that case you are not always facing your laptop and the laptop microphone may not pick up your voice well. The relatively small expense of adding a USB microphone to your laptop will solve that problem, besides much improving the quality of your voice. You don't need to be a podcast star to benefit from that external mic. My preference is a Blue Yeti, but there are many good ones.

Move your laptop up

Finally, Zoom users often set their laptops so that they are looking down at it, as you would normally do when typing. However, this generally results in an unflattering view of your face as the other meeting participants are in fact looking up your nose. Better to set your laptop on a shoebox or get a laptop stand to raise it a little higher so that you are facing the laptop camera without looking down.
